I agree, low melt solder is the best approach. Having said that the way you're supposed to use the solder sucker is to heat the joint with the soldering iron and once the solder is molten you quickly remove the soldering iron and put the solder sucker fully perpendicular against the board and release it so you're covering the entire hole and pin with the solder extractor. When you do it in that manner it's actually pretty effective.
I have been getting into appliance control board repair because of you. It is absolutely wonderful to see your approach to this. A lot of Maytag, Samsung, LG and GE customers I have are thanking me, but they should be thanking you. You are an absolute artisan and I wish you nothing but the best, sir.
50 yrs ago I used solder-suckers and the procedure was to quickly remove the iron to fully encapsulate the joint with the nose of the solder-sucker for maximum suck. When I was faced with doing hundreds of through-hole component desolderings, I spent $375 for a de-soldering gun. Best tool purchase that I'm still using today.
Next episode of NorthridgeFix with Big Boss on vacation: Fixing a Boeing CH-47 Chinook helicopter, customer came in said he dropped it on the ground and no longer turns on, paid extra for expedited service and wants it done by yesterday Jokes aside, love these unusual repairs!
I want to say something that not many may think to mention.. but I really hope that you are staying happy and healthy Alex -- eating right, sleeping enough and getting a walk or run every other time as I know sitting at your workstation saving lives day in day out, week in week out is great BUT, you need your YOU-TIME! You have no idea how much you are a lifesaver - not only to the people you actually repair their devices but even to us, thousands of miles away who can watch your content and feel good that there is another good soul out there literally saving the world, a device at a time.. :) Keep up the good job champ and may you always be healthy.. as you seek happiness in what you do.. which you do so well!
I just recently repaired the exact same board and relay for my daughters dryer, it seems to be a common issue for theses boards due to vibration. Her relay was still good, I just had to add a wire. As always, nice job Alex!
It's not vibration it's aging of the contacts, they increase in resistance and get "hot" this causes expansion and stress on the pin nearest to the contact. That's why it's the same pin most of the time.
About giving good advices: here in Germany we have a saying for this: "Eine Ameise will einem Adler das Fliegen beibringen." Translated it means, an Ant wants to teach an Eagle how to fly ;-) Good work Alex!!!!
Some people just don't understand that there is a difference between repairing for a living and repairing for a hobby. Keep up the great videos, and thanks.
Appliance tech here. I do this relay replacement in the field about once a month for these whirlpool dryers. The quickest easiest way was with a Hakko FR-301 desoldering iron, which can also be used to resolder the new relay. Another note: I've also desoldered that wire connector pin. It happens when you get chatty with your customers.
Solder sucker is an useful tool for bigger THT solder joints. It is very helpful to add some silicone rubber tube onto the tip and let it 1-2 mm longet than the tip. It allows you to put the tip into really sealed contact with the hole without sucking too much air from around the joint. When sealed properly, the sucking efficiency is highly improved.
If more people here in America were like this guy, we’d be out of problems! Excellent and no-nonsense approach. Found by accident, subscribed on purpose!
Fantastic content! Your attention to detail and clear explanations really make the complex repair process seem manageable. I learned so much from this-thank you!
Hi Alex. Great job, but I always wrap the wire around the relay pin. This is how I make a "sub pin hole". Is very handy and also better covers the relay pin. Think of it as a pin hole. Keep making good videos as they are very educational and include various tips and practices. Best regards from Belgium. Andy.
That type of failure of a soldered joint on a relay or inductor is usually caused by metal fatigue of the solder, due to vibration and lack of mechanical support of the component. I would always put some hot melt glue or similar around the relay to take the vibration stress off of the soldered joints.
How do you know that the old relay failed? It looked to me that the relay pin was burned due to arcing at the failed soldered joint the heat from the arcing would also cause the track to lift from the substrate.
Or excessive current flow, and oxidisation of the solder. I recently replaced 4 identical relays on a solar inverter, and there would have been no vibration in that.
Solder suckers are very effective and quick for removing through-hole components. The problem here was the protective coating. The transparent coating over the board is called "conformal" coating and is available as a spray-on product.
Solder suckers are just junk. I’ve tried giving them a fair shake, I really wanted them to work. I’ve tried probably nearly 20 kinds of them. I’ve tried adding extra solder, I’ve tried adjusting the heat from the iron to keep the solder flowed longer, I’ve tried adding extra flux to help the heat remain, I’ve tried putting the sucker perpendicular to the board (which is nearly impossible under microscope). They are just junk. Plain and simple. There are much better methods available. The poster above me is absolutely right, the solder is cooled and hardened before the sucker even becomes perpendicular. But thank you for explaining what the word “perpendicular” means, none of us had any clue 😂
I went to a computer/digital tech school from 96 to 97. We were issued a case with all the tools we needed and a breadboard. That exact solder sucker was in that tool case, and I still have it. Only rarely used it.
I have to comment right away after i hear to my big boss idol about complaints.. You know guys there's alot of technician around the world but all i can say is,, THERE'S NO TECH IN THIS WORLD LIKE THIS GUY REPAIRS IN EXCELLENT QUALITY! Why i said excellent? Well i'm also a technician and i lack of tools to do the job in quality because of the pricey tools. Aside of tools this guy has a proof of working a device thru video and uploading at youtube. Man i wish you a good health and happiness on your family. Keep up the good work and make your customer happy. Man im so jealous hehe.. Much love from Philippines Lapu-lapu.
Solder sucker is good, maybe, it's because you are used to in using the solder wick,I've been fixing electronics for 37 years, using the conventional way, still using the solder sucker, I don't have enough money to be a "high tech" technician, but I always make sure that my costumers are satisfied....,no backjob, Americans are always for the pay....sorry for that.....we are of a different race.....I am proud to say, I am a pure Filipino, and you are, I am sorry, I don't know if you are a true blooded American....✌️...anyway, congratulations, and I admire you for fixing troubles in less than 30 minutes👋👋👋👋......I am one of your subscribers.....🙂
Solder sucker works fine, when you need desolder any tht components, but after sucking solder jonit you need still using solder wick but save them. Solder suckre works better when you mixing unleaded tin with leaded. Regards 🙂
I have the same machine and have had to do this repair on my machine as well. exact same board. I've also replaced the pressure sensor and still have to replace a few caps on another board for a common SUDS F35 Error. always a great feeling when you can repair our own household items.
Your jokes are sometimes difficult to distinguish from your regular analyses. It's not that you can't joke, it's just you're the type of person we like to always take seriously. You keep us on our toes. My grand dad was similar. I could never tell when he was being serious or was just taking me for a ride.
I replaced this same relay on our dryer. Old one fried, I heard a pop & smelled smoke. I took the dryer apart & found part of the board fried next to the relay. I put a new relay on & "jumped" a wire were it fried on the board. Working fine for 3 years now, still working now.
Great repair and at the end of the day you are educating them and me. They make the world going. We cannot live without them? We all have something to complain in life. Both solder sucker and braid have its application and I use both.
Its nice to see you are being cautious about exposing us to the UV light at the end. Enough people must have complained about being exposed that you are starting to listen. :)
You are awesome technician. I love watching your videos. You are my main reason why, I got into repairing electronics as well. I hope to mee you one day!
I'd just like to take a moment and thank you for uploading videos over the weekends. Just feels like hanging out with a friend and shooting the breeze for 10-15min each time, even if you cant hear me. Whats your plan for the old scope camera you have sitting on the bench? Backup or another station maybe??
I'm not a RUclips whiner and you're amazing but the coating on a dryer board subject to high humidity was worth it. I wish I could fix stuff as well as you can, you've taught me a lot, Thank you.
I really like your videos I have learned so much from those videos I had business in Libya fixing gaming consoles PCs phones but in war I had accident I stopped working for awhile till I recover . but I used this time to learn more and thanks to you sharing this knowledge I know and I'm sure that that when I'm back I will be like next level from all I have learned . Much Thanks And keep up the Better Than Factory Work .
PCBs that are used in most Whirpools are known to have really hard solder and their holes have rings on the both sides.The best way to desolder with a hand vacuum pump it is also to add lower temperature solder and heat it up well.Usually 60/40 or 60/37 works well for me.
I bought a really high quality solder sucker before finding your channel, and it was the same story, if you didn't have a lot of solder on the joint it wasn't effective, and it never fully removed all of the solder, there was always a little bit left in the holes you had to heat to remove... Then I found wick, but didn't have good flux 🤣 everyone starts somewhere, but your channel has helped me tremendously increase my ability to troubleshoot an issue, and save time through more effective applications
Good story. It is not uncommon for a hole to look empty of solder after sucking and/or wicking, yet the component seems to still be stuck (especially PTH DIP packages). This is because the leads of the component usually TOUCH the hole plating someplace, and a solder bond remains at those points. My preference is to remove component with low melt solder (which is super easy on both the PCB and the component), THEN clear the holes of solder. The net cost of repair is slightly higher, but the finished repairs are invisible; i.e. you cannot tell where the repair occurred 👍.
After watching all your videos for so long took me awhile to finally decide to fix my Nintendo SP which wasn't charging for years and after my first attempt its finally fixed. :)
Hi Alex I'm from Durban South Africa,Humans have more complaints than solutions,I'm a avid follower of ur you tube videos, thanks for the great videos and ur advice, Thanks Raj Singh
I repaired my board by just soldering the burnt spot .. a search found the solution and it seems the power surge of a relay is too much for a trace... it was years of use before it failed....i tried resoldering first as that was the common repair... it has worked perfectly for 2 years now... another repair option was a Wire to replace the trace or just wiring in a relay externally to board.... not an expert like you but hey it was a working dryer after and saved me $$ I been repairing stuff for over 50 years and fixed a Security problem on my car with a resistor ( another Search tip that worked )... the other option was about $400 in parts/programming that was the repair told to me from Mechanics at Dealerships ( friends )... i took the less than $10.00 option ( i bought a pack of resistors after a multimeter showed me the resistance i needed ) ...it ran perfectly after that and fixed the Crank No Start issue.... 🇨🇦🤓🤟
Sucker does a good job if you point it "vertically" right at the joint, not from the side when it just "gasps" air around. I actually have exactly the same kind of sucker.
I did this repair myself on my Whirlpool dryer. There were a few videos online about it. Turns out most people don't need the relay replaced, they just need to scrape back some of the protection film and then re-melt the solder to the blow pin of the relay. Worked for me without replacing the relay... just the solder connection had popped.
Great Video Alex! Strangely enough I recently replaced 4x relays which look identical on a solar inverter repair. I also had to repair a few tracks that were burnt out due to high current flow so I used 2.5mm2 solid copper wire to beef up the tracks. Great Job. Well Done!
I used to work this kind of job many years ago and now I'm an avionics technician... I miss this job. A week ago I went to visit my sister and her induction cooking plates weren't functioning and the smartphone of my niece... Last time I repaired something, was so long ago, that there weren't any induction cooking plates yet and that was my first, but it wasn't something complicated and the problem was similar to this board. And I managed to fix the smartphone, all done on a kitchen table with not many tools to choose from.
9:15 A small "C clamp" works great too in situations you cant (or dont want to) put your hand close to the work area. Can pick up a nice light weight small one from harbor freight tools, or any other tool place pretty much. Just be sure to not twist the thing down and crush a component.
In my former job, I liked to use a Weller rework station with vacuum pump for desoldering. It was very convenient to use it sometimes, but I wonder how practical and economical this kind of equipment is when it comes to daily use. Alex, have you had any experience with this kind of equipment?
WELLER is a world class maker of soldering equipment. The soldering iron in this video is by Weller. They design tools to be used DAILY, by professionals.
I replaced Whirlpool boards in my previous appliances. I can't help but think this expedited repair cost more than a new board or even a used on Ebay. I would do this repair now but my skill level back then wasn't the same but mostly diag. skills. I do appreciate the content though. I have also used solder suckers in the past. I have a Metcal vac. desoldering unit but never actually used it as it requires compressed air. I believe there are now stand alone units. I think someone made a great comment that doing this as hobby like 99% of us and Alex doing it his way as a business is very different. I would defer to Alex's methods 100% over mine and or anyone else's. He knows what works for him. I watch another guys channel IC Weld and he has a great saying. "I'm not telling you how to do it. This is how I do it."
Many of these are discontinued and available parts have all but dried up. The control board for my Duet washer is now well over $300, and the motor controller comes in around $250. Ebay with optional 2 year warrantee for the win!
My Maytag epic dryer basically did the samething.the trace burnt up just from use. Used some Thick wire to patch the trace,then flooded the trace with solder to beef up the current capacity. planned obsolescence!! Every year like clockwork in sept-oct i have to replace the heating element,which is fine as i take the Opportunity to strip down the whole dryer and clean all the lint out.bout every 3 or 4 years i replace the belt,rollers etc. Just keep the parts i need on hand,and order replaces when i do the work. I refuse to move into a newer dryer as they are a pita to work on,have higher costing parts,and fail more often.
Grate job, Alex... it looks easy. But doing it is much more difficult. I'm still in training, but hopefully, I'll get there. Thank you for the contents. Keep it up
I solder maybe 20 things in my life.. but i watch you because of sense of humor (mostly) another great guy is Ave.. but you have a bit of russian accent. all the best from Croatia
Pro Tip with solder suckers. Melt a little extra solder into the location, then suck all that solder out. Solder suckers are not for every situation. They were designed for PTH, that's where they work best. Like everything else, it's a technique and a tool that takes practice.
Some positive vipes from me. Your Videos inspiriered me to run my own Business in Germany for next Year, because of your positive vibes and sharing your experience. It make me Happy to Solder! Currently I buy defect parts or search for defects to repair for free, to run my experience to make it better than Factory. :) Yesterday I repaired my first Hiroshima Nintendo switch Board with 10 Missing Pads out of your experience! I do it in 4h. I know this is not worth in Business, but it makes me better for later Business. :)
Nail polish does work, but there is a similar product that works better. If you go to a musical instrument store you can get liquid Nylon that classical guitarists use to strengthen their nails. It works surprisingly well.
"we got this board 2 days ago, we ordered the part right away, we got it the next day, and now we gonna invoice and mail it back to the customer" I expected it to end like: "and now we gonna charge $800 and send it back to the customer" :D
Hello Dear Alex great work, this is my specialty i repair every electrical PCB Board as i see this is the first time you have accepted a washing machine PCB board so it's different from computer repairing because components of computer boards only work by D.C. but components on an electrical PCB boards are working by both A.C. and D C.
this is a dumb question, but what does the solder mask look like from the side-view, is there a noticeable ridge/bump due to the added solder+ material, if that is the case how would you make it flat..?
I have question for you: When you work on PCB to do soldering and repair work, is your eyes will be concentrated on the work piece or on the telescope screen?
That was a great fix. I would like to know how would you repair a proprietary eprom chip? Could you ask the manufacturer of the board if they can send you a new Eprom chip?
Greetings. I must that that is absolutely a beautiful job. Previous to watching this video and hearing your explanations given about your reasons for using lowmelt solder, I was also wondering why you were not using solder sucker also. I can certainly see the value in you doing things the way you do. Thanks for sharing. Be blessed.
When i work on a board that was sealed, most of the time i use the mg chemical 422b formal coating, it stick to anything, you can spray a very thin coat and it dry in 10min, its literaly a silicon based product. you should try it someday, im sure you would like it.
Two relays were replaced on my oven's PCB due to a power surge caused by a storm. * The oven was ON during the storm Also a relay was replaced in my Onkyo stereo amplifier due to the same lightning storm. * The Onkyo receiver was OFF during the storm. (** I recommend turning off devices at the breaker electrical panel or unplugging the device during a big storm. Unplugging the devices is sometimes not practical due to the location of the outlet and the number of devices requiring to be unplugged)
Most likely unleaded solder. I also use low temperature solder. My experience I tin the legs of the relay first. Sometimes it’s hit/miss if you don’t tin the legs. I have used discarded solder wick and an exacting knife to redo the trace.
I agree, low melt solder is the best approach. Having said that the way you're supposed to use the solder sucker is to heat the joint with the soldering iron and once the solder is molten you quickly remove the soldering iron and put the solder sucker fully perpendicular against the board and release it so you're covering the entire hole and pin with the solder extractor. When you do it in that manner it's actually pretty effective.
Agree
And adding more solder is helpful when using solder sucker.
Was gonna write th same
@@requiem4adreamc I sometimes use a toothpick to enlarge the hole in the board while the solder is still hot. Works great.
Agree, sucker is usuable specially when brandNew like that one. But like this bro just said, you must retire tip when using socker
I have been getting into appliance control board repair because of you. It is absolutely wonderful to see your approach to this. A lot of Maytag, Samsung, LG and GE customers I have are thanking me, but they should be thanking you. You are an absolute artisan and I wish you nothing but the best, sir.
I think he made several careers.😂
I learned today: don’t need a sucker and don’t be stupid
Oh it was really neat watching you repair the board!!!!

Exactly this, even to use a solder sucker it requires technique. Alex didn't use it that well.

Pro Tip: Add fresh solder to joint before solder sucking. I do this all the time, works very well.
Solder suckers are just junk, bro. You can do the same thing but better, with other methods. Pro tip from a bigger pro than you. Trust me.

it was years of use before it failed....i tried resoldering first as that was the common repair... it has worked perfectly for 2 years now... another repair option was a Wire to replace the trace or just wiring in a relay externally to board....
not an expert like you but hey it was a working dryer after and saved me $$
I been repairing stuff for over 50 years and fixed a Security problem on my car with a resistor ( another Search tip that worked )... the other option was about $400 in parts/programming that was the repair told to me from Mechanics at Dealerships ( friends )... i took the less than $10.00 option ( i bought a pack of resistors after a multimeter showed me the resistance i needed ) ...it ran perfectly after that and fixed the Crank No Start issue....

Sucker does a good job if you point it "vertically" right at the joint, not from the side when it just "gasps" air around. I actually have exactly the same kind of sucker.
I did this repair myself on my Whirlpool dryer. There were a few videos online about it. Turns out most people don't need the relay replaced, they just need to scrape back some of the protection film and then re-melt the solder to the blow pin of the relay. Worked for me without replacing the relay... just the solder connection had popped.
Great Video Alex! Strangely enough I recently replaced 4x relays which look identical on a solar inverter repair. I also had to repair a few tracks that were burnt out due to high current flow so I used 2.5mm2 solid copper wire to beef up the tracks. Great Job. Well Done!
I used to work this kind of job many years ago and now I'm an avionics technician... I miss this job.
A week ago I went to visit my sister and her induction cooking plates weren't functioning and the smartphone of my niece...
Last time I repaired something, was so long ago, that there weren't any induction cooking plates yet and that was my first, but it wasn't something complicated and the problem was similar to this board. And I managed to fix the smartphone, all done on a kitchen table with not many tools to choose from.
9:15 A small "C clamp" works great too in situations you cant (or dont want to) put your hand close to the work area. Can pick up a nice light weight small one from harbor freight tools, or any other tool place pretty much. Just be sure to not twist the thing down and crush a component.
In my former job, I liked to use a Weller rework station with vacuum pump for desoldering. It was very convenient to use it sometimes, but I wonder how practical and economical this kind of equipment is when it comes to daily use. Alex, have you had any experience with this kind of equipment?
WELLER is a world class maker of soldering equipment. The soldering iron in this video is by Weller. They design tools to be used DAILY, by professionals.
Radio shack used to have a soldering iron with a solder sucker built into the tip.
Thank you because you talk about scam people on telegram. You make me feel good. Thank you again
I love your humor Alex. Most scientists don't get it. Don't let them wear you down.
I replaced Whirlpool boards in my previous appliances. I can't help but think this expedited repair cost more than a new board or even a used on Ebay. I would do this repair now but my skill level back then wasn't the same but mostly diag. skills. I do appreciate the content though. I have also used solder suckers in the past. I have a Metcal vac. desoldering unit but never actually used it as it requires compressed air. I believe there are now stand alone units. I think someone made a great comment that doing this as hobby like 99% of us and Alex doing it his way as a business is very different. I would defer to Alex's methods 100% over mine and or anyone else's. He knows what works for him. I watch another guys channel IC Weld and he has a great saying. "I'm not telling you how to do it. This is how I do it."
Many of these are discontinued and available parts have all but dried up. The control board for my Duet washer is now well over $300, and the motor controller comes in around $250.
Ebay with optional 2 year warrantee for the win!
glad he could save it from the landfill though
My Maytag epic dryer basically did the samething.the trace burnt up just from use.
Used some Thick wire to patch the trace,then flooded the trace with solder to beef up the current capacity.
planned obsolescence!!
Every year like clockwork in sept-oct i have to replace the heating element,which is fine as i take the Opportunity to strip down the whole dryer and clean all the lint out.bout every 3 or 4 years i replace the belt,rollers etc. Just keep the parts i need on hand,and order replaces when i do the work.
I refuse to move into a newer dryer as they are a pita to work on,have higher costing parts,and fail more often.
I use clear coat for automotive use to replace conformal coating. Worked fine so far.
I like it when you save the world from complaints 😂
You can seal the board (waterproofing) with plastic-spray. It’s like a thicker clear spray paint.
Do you use low melt solder to add the component back?
I really like the smile when you have a part fixed, It's nice to see how happy you are. :-D
that trace repair looks amazing, you're the Man!!
I 'think' the solder mask finished the job off perfectly 😆👌 ...enjoyed the video, thank you 👍
Hey Alex, Must say that was a "wicked" job!
When you are a newbie, a solder sucker can be life saver.
Grate job, Alex... it looks easy. But doing it is much more difficult. I'm still in training, but hopefully, I'll get there. Thank you for the contents. Keep it up
I solder maybe 20 things in my life.. but i watch you because of sense of humor (mostly) another great guy is Ave.. but you have a bit of russian accent. all the best from Croatia
On older audio boards the solder sucker usually rips the traces on the board. I avoid using it.
Honesty is the way to go! You earned a new subscriber man! And the joke was actually funny!
Pro Tip with solder suckers. Melt a little extra solder into the location, then suck all that solder out. Solder suckers are not for every situation. They were designed for PTH, that's where they work best. Like everything else, it's a technique and a tool that takes practice.
"Save the world from complaint" , LOL you are No 1 !!!!
This is why I have a Timer switch model, with filter you pull from the top of the unit, Simple and efficient.
Very nice job fixing it and explaining how to fix it.
Some positive vipes from me.
Your Videos inspiriered me to run my own Business in Germany for next Year, because of your positive vibes and sharing your experience. It make me Happy to Solder!
Currently I buy defect parts or search for defects to repair for free, to run my experience to make it better than Factory. :)
Yesterday I repaired my first Hiroshima Nintendo switch Board with 10 Missing Pads out of your experience! I do it in 4h.
I know this is not worth in Business, but it makes me better for later Business. :)
Always enjoy watching you work. Great Job🇧🇿
Nail polish works as well as conformal coating in my experience and can be used to cover up parts where the original conformal coating got removed.
Nail polish does work, but there is a similar product that works better. If you go to a musical instrument store you can get liquid Nylon that classical guitarists use to strengthen their nails. It works surprisingly well.
the solder sucker works on the principle of a vacuum. you did not enclose the joint before activating it.
Nice work. Love the vocals👏
اكيد لبناني طريقة كلام لينانيه هذه 😂😂😂 بحب قناتك يا اخي كثير بحبها 😊
"we got this board 2 days ago,
we ordered the part right away,
we got it the next day,
and now we gonna invoice and mail it back to the customer"
I expected it to end like:
"and now we gonna charge $800 and send it back to the customer" :D
I think you did a great job Alex 😃😃
Hello Dear Alex great work, this is my specialty i repair every electrical PCB Board as i see this is the first time you have accepted a washing machine PCB board so it's different from computer repairing because components of computer boards only work by D.C. but components on an electrical PCB boards are working by both A.C. and D C.
I think bc he can repair without any assemble or disassemble. Firstly doing the jobs that no need to disassemble. Smart move. He using his brain 😁👍
this is a dumb question, but what does the solder mask look like from the side-view, is there a noticeable ridge/bump due to the added solder+ material, if that is the case how would you make it flat..?
I have question for you:
When you work on PCB to do soldering and repair work, is your eyes will be concentrated on the work piece or on the telescope screen?
ابداع لا ينتهي..شكرا اليكس
After I repair waterproof boards like this I apply clear nail polish over the joints. It seems to work fine on the repairs I’ve done.
Very good suggestion, my friend !!
Fun fact copper oxidation is called patina not rust. Rust specifically means iron oxidation. Science lol. Sorry if I am annoying had to.
Don't apologize for being annoying you can't help it.
How is that annoying, it’s a cool fact
I was going to say something along those lines, but I thought might be best not to lol
@@areyouserious3092 How nice of you
This time I enjoyed what you said more than what you did with the relay 😆
It's so funny the people that can't read dry humor 🤣 I love Alex's dry humor 🤣
That was a great fix. I would like to know how would you repair a proprietary eprom chip? Could you ask the manufacturer of the board if they can send you a new Eprom chip?
polishing is not free... I love it.
This dude will attempt to fix anything, love your vids!

Greetings. I must that that is absolutely a beautiful job. Previous to watching this video and hearing your explanations given about your reasons for using lowmelt solder, I was also wondering why you were not using solder sucker also. I can certainly see the value in you doing things the way you do. Thanks for sharing. Be blessed.
I just like seeing solder mask being applied because it's kinda cool.
When i work on a board that was sealed, most of the time i use the mg chemical 422b formal coating, it stick to anything, you can spray a very thin coat and it dry in 10min, its literaly a silicon based product. you should try it someday, im sure you would like it.
With the effects of inflation, repair "throw away" appliances is becoming more cost effective and desirable. Nice job again.
Considering this is not normally the sort of board you work on, you did a great job on it.
Not "you" but "we"!
Nice work, you can buy the conformal coating but it takes ages to dry
I would love to learn this craft. Any suggestions? I have access to junk ecms for heavy equipment so plenty of materials to practice with.
Plenty of videos on youtube about it. Just put it in the search box.
Two relays were replaced on my oven's PCB due to a power surge caused by a storm.
* The oven was ON during the storm
Also a relay was replaced in my Onkyo stereo amplifier due to the same lightning storm.
* The Onkyo receiver was OFF during the storm.
(** I recommend turning off devices at the breaker electrical panel or unplugging the device during a big storm. Unplugging the devices is sometimes not practical due to the location of the outlet and the number of devices requiring to be unplugged)
Most likely unleaded solder. I also use low temperature solder. My experience I tin the legs of the relay first. Sometimes it’s hit/miss if you don’t tin the legs. I have used discarded solder wick and an exacting knife to redo the trace.
