It's OK to have sponsors, it helps the channel and it's also related to electronics! Keep on the good work!
I don't mind sponsors too, when it is an item I can use. I do have a problem with the ad's that don't have a thing to do with the video, like a moving ad or health ad that's showing bed bugs, that have nothing to do with what they are selling.. I know he can't pick the ad's.
Thank you. One thing for sure I will always keep things relevant on LER when the choice is within my control
@@LearnElectronicsRepair 🙂 your welcome. been learning more on LER vs any other RUclips channel, I even got a few meters to help me out, once I can stand for longer times and lift up more then 8 1/2 lbs. Before finding LER, I got one PSU running for 6 months more before it blew out something else, now I know what to check, thanks.
Hi Richard, I just wanted to say I adore your channel and have learned so much from you. I recently started a job involving power electronics, and I have been using your channel to learn and review practical things so I can eventually diagnose and repair stuff around the lab if needed. I’ve also been learning to solder large-ish SMD components on aluminum boards (basically what we had lying around unused), and your advice to switch to a chunky tip is life changing! I don’t have a bevel style, but the chisel style I’ve got at work is still a world of difference over the fine point! Today I successfully desoldered and resoldered a four pin chip on an aluminum board using your techniques! Previous attempts had me overheating and ripping pads off (a different board) lol. So again, thank you so much for your channel and all the solid education you provide people like me getting into the field. Ciao!
Thanks so much! I have been practicing desoldering and soldering tiny smd resistors on a pcb, in preparation for a repair I will do on my 1999 Buick Century instrument cluster, to fix my odometer display. So far, so good! I have the courage to try, and with a bit more practice, I will gain the confidence to succeed. Your video is very helpful, andI truly appreciate you sharing your knowledge! Lil hugs
Were you able to accomplish the repair?
Well, after ordering the right resistors, and practicing until I was very confident to begin, the new soldering iron that I bought 30 days prior, totally quit working, and I could not get a refund! I was so upset, and disgusted, so decided to just let it go for the time being...but shortly after that, my car blew the head gasket, so I sold it to my mechanic and bought a nice Lexus. I did give the resistors to the mechanic so he could do it before fixing it up and reselling. All of that for nothing! Oh well...thanks for asking! @@guyhappy60
Since watching your videos I’ve switched to a fat tip and it’s a complete game changer. So many times I’d resort to the heat gun only to make a mess, fat tip seems to do it no problem.
I'm not experienced in such fine electrical repairs but found this channel to follow along with on how to learn. I scored a free washing machine and upon inspection found it has a fried component on the circuit board. It appears to be a black 3 legged SMD ACS1086S transistor. It's the only part of the board that looks fried. I hope that my attempt to repair it is successful. Thank you for sharing your knowledge and expertise.
How much heat can you usually subject components to before they are damaged?
Unknown variables. Too many unknowns.
@Big Bass Yes, as a returning "enthusiast" I wondered if there was a new "rule of thumb" rather than having to consult various data sheets, thanks for your reply 👍
@@plaistow001 With modern components at least I think you will find the answer to your question is 'far more than you would expect'
@@LearnElectronicsRepair thank you!
I love chunky tips - no variations in temperature due to high thermal mass so very consistent results
"you must agree that looks, almost, professional" and it does indeed.
Thank you for this great instructional video
You rock!
I'm involved in the restoration of a 53 year old boat.. All the internals are past saving. (it looks like it was full of water for 10 years) For once a very useful sponsor.. Thanks.. I'll be checking them out when the time comes to make up a completely new wiring harness.
Why do you intend to have wire joints in a new harness?
@@alanrichardson1672 Because wires have to go through internal bulkheads.. it's not a rowing boat
BC2 is my go to tip! I use a reverse cross tweezers to help alignment when I'm adding caps in parallel and works great. I like the fact that the tip is just big enough to cover 2 0805's stacked.
Richard what about hot tweezers ?
I've never used them so probably would make a right pigs ear out of it. Maybe someone would like to send me some to review?
I've found this channel to be very educational, thanks!
Thanks Rich for sharing your expertise ..much appreciated..wishing you continued success.
Thanks for your support, it really is appreciated 🙂
I also use the BC3 tip for a majority of my work, Rich. The heat transfer is brilliant. I have the BC1 and 2, also. They get used on occasion.
That solderstick looks like a game changer
"A bad workman always blames his tools," because he doesn't bother getting the right ones. Sage wisdom right there
Lots of ways to do this, and it all comes down to personal preference. For hand soldering 0402 up to SOIC, I get great results with a 0.8mm chisel tip (Hakko 900M-T-0.8D) under magnification. Easy peasy.
And this is exactly what I am😉 saying - find a method/tip that works best for you and stuck with it until you can do it almost without looking
It is totally alright to make some money, to pay bills and cover your time. Thanks for the instructional video.
Such a good technique, I was sort of doing that my self when I didn't want to but it didn't occur to me that I should actually do it when I'm removing a shorted component to save blasting everything with hot air. The only problem I can think that would come up is if its a really densilty populated area around a microchip but I think at that point I could just come in from the top and get the solder heated on both pads either side.
Also having some inverted tweezers where its by default grips and you have to squeeze them to open them apart are quite handy for handling SMD components. They have ceramic ends on them.
Yeah I have some of those inverted tweezers but they are not fine enough for this sort of work - do you have some very fine tip inverted tweezers, I would be interested in trying some.
@@LearnElectronicsRepair I have 1 set being the white ceramic inverted tweezers which I got from Amazon, I also modified them a bit because for smaller SMD components they would grip to tightly so I used bluetact to adjust the strength. This was for hand soldering 0402 components because I can imagine with the hotair gun it would easily melt the blue tact.
I also have another pair which I got from ebay which have a slider that allows you to adjust the strength and lock them which are jewelery industrial tweezers, these do have a very fine tip on them.
which reminds me I will have to look at what other tools jewelers use because I am still struggling with handling 0201 SMD components and havn't really come up with a good solution yet, even with using inverted tweezers. Anything above that size though is fine.
I was also using a magnet to get the SMD to sit flat while I would grip components with either tweezers, it just made it a little easier than having them fly into a portal and never see them again.
i also own ksger t12 soldering station and i usually used D style chips, and K type tips for smd qfn packages.
These are all great videos I learned a lot. keep up the good work
I use the chisel tip for everything as well.
That sounds like the golfer's saying, "A bad golfer always blames his clubs." Or the weather, or other people standing nearby, or the ball, etc.
Hello Richard! You can slightly bend the sharp tip by pliers, like Sorin do! This way much better to use it)
Or just buy a bent one - actually that is my second favourite tip since I was forced to try it on a sponsored video recently 😉
Hi bud I got a gpu rtx 3070 ti suprim it will load up to the window but as soon as you go to try watch a RUclips video or really load anything my screen goes black and cut out I was just wondering if you had any idea of what could be wrong with my gpu cheers buddy p.s love your video's
Hello how much heat can these surface mount components take before frying them? Is it better to go in high for a short time or low temp for a longer time?
What do you recommend for pulling the aluminium dome out of a tweeter that has been pushed in by a child? Would a SMD vacuum tool with a little sucker on the end work?
i got some of those solder sticks. the are quite decent. howeve i dab on a touch of flux to aid flow.
Please order test ksgr green or black soldering iron handles named carbon fiber. Some say it gets too hot, others like it very much.
I've looked at those carbon fibre handles and always fancied trying one, if I have some money to spare I will get one
I had nightmare experience with tiny smd capacitors and resistors and chips. It was a mess, very hard to clean, even worse many missing.
Sponsored videos are all fine long as they are not those scammy things out there.
Think they done away with those become a “Scottish Lord” with just 1 sq foot of disused brown-land on the Outer Hebrides. Lest we forget the penny auction sites. Haha
Cool stuff
Are you not afraid of damaging parts when applying heat? I just bought a light reflection sensor and in the datasheet it mentions quite a low maximum lead temperature, about 260 degrees C.
Thanks for a very useful video any chance of following it up with identifying smd components resistors are fine but caps dont appear to have any identifier, transisitors sot packaging seem very confusing i was trying to fault find on something recently and the device was marked 6B with a 5 rotated 90deg . thanks again
Unfortunately the MMLC capacitors have no markings - but there are some things to talk about regards SMD resistors, I'll do that on a future video
Hey all. Won't it ruin the caps when it's being desoldered that way?
Richard I use the 245 sk tip to remove the parts it goes on both pads on most parts it too it rather chucky and the knife is ez to get into places 73 n4jrs
Could you try the same test again using a type k (knife) tip? I'd be interested in seeing how that works.
Yeah I can do that
why does the component have to be perfectly flat?
Hi, is it possible for you to show us how to remove and replace a CPU socket on a motherboard ?? Thanks !
I did try that on an old video with basic tools. I didn't end well. I should revisit that and try again
ruclips.net/video/x9Xiv19Kx-8/видео.html
Also this one may interest you: LGA Socket Broken Pin Repair
ruclips.net/video/oiBqW22Wl2s/видео.html
Note the production quality on my old videos is not so good as the later ones, it's been a learning curve
Heya, a bigger tip brings heat in much more easier that's a fact. but still everyone has to find his own way how to solder I guess
Great video Richard. I tend to use 1.6mm tip to do most of my rework, but I will try a chunkier tip and see how i get on.
By the way, you failed to mention two tools you used throughout your video and that was the twicers and the magnification unit you use. A little recommendation on those tools would be appreciated.
Tweezers*
@@dvsr5296 Agreed - I will do it
i think heating the pad for so long will destroy the pads in low quality boards.
For me. Easiest tip is the bc3
And totally my favourite too, I found this by chance when I could not be bothered to swap the tip for a fine tip one day, and thought, 'well that worked better than I expected' so tried it a bit more and now I am totally sold on it
Maybe u wanna try c4. It bigger
The one thing you did not do was test the removed components to see if they could be reused ?
To be honest that wasn't within the scope of this video, I was just trying to show how to desolder and solder them.
Hi Please stop the advertising adds As I just skip over and use FREE adblocker plus and get no youtube adverts
If you do not like advertising fine just skip it but do not tell him to stop because it funds the channel you airhead !!!!
@@Dutch-linux I have a right to my views, As have you, to your views about Advertising. Better to have air in the head than nothing at all, Really shows your intelligence bully level when people resort to name calling for every one to see what you really are. PS is this a 15 minuet argument or have you paid for the full hour.
OK, let's talk about this. So you think I should stop all monitization on this channel and do all of this for nothing (no money to pay my bills and enough spare to live, from the advertising that you don't want to see) because when I have the audacity to try to get some income for all the effort (currently 60 hours or so a week I am putting into LER) then it annoys you. And it seems you have some likers/thumbs up too who agree with you.
Fine, no problem obviously you think that every time you watch one of my videos it is totally worthless, you gained no pleasure from it and learned nothing from it. I will actually agree with you as I dislike ads possibly as much as you do (unless I find them relevant to me). If you remove your ad blocker when you are on my channel then maybe you will pay me 10 cents a month or similar if you watch all my videos. If you don't then I earn nothing from you. Now I will ask you a honest question and would like an honest answer, Do I entertain you or educate you enough to be worth a few cents a month or is the answer no? I accept you don't like ads but actually there is another solution, block all the ads and then pledge me €1 a month on Patreon. Or maybe what I am trying to do is totally worthless. Would you work those hours and if your boss thinks you should do it for free, are you OK with that? Also I deliberately put chapters on this video, which I do not usually do, to let you skip over the solder sticks advert, though actually IMHO they are rather useful otherwise I would not have agreed to the promotion in the first place
Or why not suggest to me another way I can put as much time an effort into this, because I really enjoy doing it, and still let me make enough money to live off (I have no desire or interest to be wealthy) and I will try that instead and not annoy you any more if it works out.
@@LearnElectronicsRepair Your videos are worth every penny you can get from your sponsors and more and that is still under valuing your videos and skills - RUclips are the ones at fault with there enforced adverts and pittance in payment to it's hard working video contributors like yourself, If it was not for the video makers youtube would flop over night. So that is why I posted my comment about adverts. But it is your channel to make videos as you see fit and youtubes website and it will never change But can only get worse !
@@uksuperrascal I do agree with you, unfortunately I have no control (unless I am wrong) about the type of ads that YT insert in my videos. I wish I did or at least could narrow the selection down to 'tech'. Clearly there is some sort of selection process as a reasonable proportion of the ads I see in my own videos are electronics related, but then I see ads for travel travel related stuff for example. Also different viewers must be getting different ads (type and quantity) as I do see a proportion of ads in Spanish but I guess that is based on my location. While typing here I just saw a mid roll ad for fork lift trucks, tractors and diggers on this video. Quite how that fits the channel or my personal viewing profile, I have no idea.
One thing I do control is anything I accept for sponsorship or reviews. You may be surprised how many offers I turn down, mostly related to 'generic consumer electronics' and sometimes to 'software keys' or weird stuff like wall art made from exploded smart phones! Anything repair or electronics hobby related i generally accept
