This video of your 's Sir Alix can give me lot of help specially by using hot air machine. I had not training o nore been attended any seminar. I bought my hot air machine this June of 2021 and no idea on how to use it and on what temperature i use to be. But now because of your video i now know on how and what. I been a tv and audio technician for more than 33 years. I only base on my experience and my technique and as a home base electronics shop owner and technician. Thank you Sir Alex because of your tutorials i learned so much. Keep safe.
With a two sided device, there is usually no need to apply low melt solder to both sides. Only one side would need to have low melt solder applied. Melt the low melt side first then when you heat the other side, the same result will result. This saves money and clean up time.
is there a comprehensive list for solders that are considered low melt solder? trying to figure out how to go about the research or where to find the info.
As an amateur repairing only my own electronics I have been using kapton tape to protect surrounding components from the heat of the reflow gun while using only the small nozzle in close quarters. I'll definitely try using some of my low melt solder next time. I mainly replace charge ports on my wife's tablet at least a few times a year because she uses it a lot to play games on and always has it connected to the charge cable. My reflow gun made the greatest difference regarding success rate during the port or part removal process while sparing the pads on the boards to boot. I tried using a cheap desoldering station earlier that melted the solder then vacuumed it up and it always seemed to leave just enough solder residue to keep the part from releasing. This cost me a pad or three that I had to spend more time repairing. Yes, the solder wick does an awesome job clearing those little holes that those tiny prongs of the charge port stick into before soldering.
Very good demonstration! I've soldered stuff very long as a hobbyist but never thought of low melt solder. I'll sure try that on one fix I have waiting for some desoldering and resoldering.
Irony. I discover your video today. Yesterday I bought three bags of Rose's metal from an eBay seller in Moldova. Rose's Metal is not anything dangerous or rare or unique. It's simply no more than little ingots of Lead, Bismuth, Tin. 50g sells for $6 Rose's Metal is my favorite low melt solder. It forms a perfect eutectic blend with OEM ROHS no-lead solder. Chipquick and the like cost much MUCH more for some reason. Maybe the same reason that Rose's Metal is treated like some National Security controlled substance top-secret threat to our supposed free market economy? Chipquick and the like have a corner on this market that depends upon this Rose's Metal and knowledge of it to remain obscure. Another expensive consumable that we use is WAY over-priced...and what do you know; it's kept safely in a convenient shroud of mystery. The soldering FLUX that we use. Most of us follow Louis Rossmann's recommendation to use Amtech 559. Many of us stick to Chipquick flux. They're both great. Neither are cheap. But I then watched Sorin (Electronics Repair School) remove the sorcery from the secrets of our flux that we use. He introduced me to Colophony. You mix it to the consistency you want with the same 99% alcohol you already have. Colophony is tree sap. That's the secret behind flux. The same seller on eBay. 200g is $6.
I've heard of rose's metal but never really used it. I may order some, try it and report back. As for Colophony, you are 100% correct, but there is more to a good flux then just Colophony and Alcohol. Otherwise all flux makers would have good flux. I've used flux that takes great effort to remove after application, or burns fast, and / or release smelly fumes when burned, and some just doesn't have the right consistency, some are clean some are no clean . Amtech seem to have a good formula that works and considering that it comes with the syringe, reasonable quantity and price, i don't see a reason why we need to reinvent the wheel, spend time mixing and possibly have something not as good for just a little saving. on the other hand, I don't think it hurts to try it out and see how it works out.
I will try Colophony when it arrives. In our flux we need good scrubbing action (removal of oxides, corrosion) and we don't want heat of working with it to turn it into tar. We don't want acid continuing on after we're done working with it. We also don't want it to be runny and to run away and evaporate under hot air most of the time. We sometimes want slightly paste-like consistency to hold chips in place for us so the component doesn't blow away and start a hide-n-seek session. (That always happens when you don't have replacements for unknown value components). I, too will put this stuff through thorough testing. To the best of my knowledge and abilities, of course...
You were saying in one of your other videos that low melt solder would have to be completely removed before soldering a component in place of the one removed. Can low melt solder be present in the insulation of a component on the pcb?
I bought my first soldering station not 2 long ago, practicing on old stuff I like it. I'm native n we don't have people around here that know this stuff. They just throw there things away n get another.
Another reason low melt solder stays liquid for so long is that a normal solder iron is much hotter than needed to melt it. So it gets super-heated and stays above it’s melting point for a long time.
Melting temp for Sn63/Pb37 is 183 degrees Celsius (361 Fahrenheit). It is a "eutectic", meaning it becomes liquid at the same temperature it solidifies. In the solder business back in the 1981-83 time frame we called it a "plastic range". The difference in melting temp and solidification temp.
Thank you very much for this experimental video. I was wondering if you ever tried using KEK Solder Paste and if so, I would really appreciate it if you can do a video showing ur experience and to elaborate your thoughts on this type of syringe solder flux compound.
Do you provide or have you thought about doing a full course on electronics repair, starting with the basics (tools required, components and how to tell them apart , etc) then moving to more advanced repairs? I would pay for a comprehensive course like this.
I spent 2.5 hours yesterday trying to remove the connector on my son's Nintendo switch because I tried to use the leaded/unleaded method. I have brought shame and dishonor to my family :)
When you re-solder the chip do you use same low melt solder alloy? For example for PS4 hdmi pins what solder do use? I know low melt solder is useful for removing chip or joint easily but do you use same low melt solder for resolder? Thanks for help!
No, only use the low melt for removal. It does not have the holding strength when cooled and would be a waste of money (since it costs so much by comparison).
I like your channel and character because you are explain whatever needs and don't hide anything to keep it for yourself nice bro I learned a lot from you and because I know you are believe in God and religion I say God Bless you
Have you ever done an a full explanation of the 1.05 volt power rail on a laptop and do you have to have a processor in place to fault find on the motherboard also what should be a typical resistance for this circuit. If you have done a video on this can you point me to it as I have a dell motherboard (09909-1 DG15MB 48.4HH01.011) that a repair shop stated was unrepairable after liquid damage even though the motherboard showed no obvious damage and am using it as a learning module for myself.
I've looked everywhere for days and can't seem to find anyone in Australia selling low melt solder only one close to it are welding rods but they claim to be low temp and melt at 400c which isn't low. If anyone can help me find a seller in Australia would much appreciate it id love to buy from Northridge but it'll cost me $50 to get it posted to Australia .
As I'm not from America, I can't purchase low melt solder from you. So, can you tell me what is chemical composition of this low melt solder so I can find it here?
You’re very generous with your knowledge and you do an excellent job explaining and it is easy for me to understand. Thank you.
Finally a video that explains how to.... A very big Thank You !!!
I have been repairing rohs soldered components for years and never knew about these techniques using low-melt solder. Thanks for sharing!
25 Years of using solder and working on electronics, never have I ever used low melt solder. It's going to be a game changer. Thanks
This channel is going places, thank you

Thank you very much for this lesson! I will be buying low melt solder and the hot air station from your site. Thanks again!!!
Maşallah Bro . Thanks from Germany for showing the benefits of this type of Solder since i been a soldering noob as an electrician here !!

I tested low melt solder this week for the first time after seeing you using. It's kind hard to get used to it, but after that, it's pretty useful :)
There is always something to learn from you.Thanks from România!

In some boards the canal is so tight that low temp can't cross to the other side.

I feel stupid, but I need to ask,... Why does my solder not HANG on my iron? it seems to avoid it at all costs.
Very good demonstration! I've soldered stuff very long as a hobbyist but never thought of low melt solder. I'll sure try that on one fix I have waiting for some desoldering and resoldering.
Great video man. Wish i knew this much when tackling my dead laptop with standard equipment. It remained a dead laptop which i threw away.
please give a setup tour all of your components like soldring iron, voltage injector etc

What an excellent explanation and demonstration
That's good video. I bought the Mechanic i Soldering XW and has good results. Alternatively, we can use low melt solder paste with a bit of mess.
a very interesting video for me about Lohman's solder.. thanks..greetings from Croatia !!
Thanks!
Thanks for going out with that precious learning. 💪
Your videos are very helpful to learn what takes experience and time! great. thank you because it helps a lot.
Im still learning and i learn alot from watching this video
Great tutorial! Thank you very much. Always learn when I watch your videos.
Thanks my man! Learning myself. This helped tones
this video deserves more likes
Thank you for the video. I learned so much. I greatly appreciate it.
Excellent job, I am sure came from many years of experience.
I really liked this video, I never used low melt but it looks really convenient in some circumstances

I have learned lots from u thanx for ur tutorials
i always use this technique it works great
Great educational video as always
Nicely demonstrated. I have an interest in the Weller soldering station you use. Would be nice to see the micro-pencil in action? Thanks again.
Weller have been *THE* soldering station for many decades. Their top-end equipment remains without peer.
How strong is this solder, I want to use it for a m.2 connector and nvme mounting stud?
Also might use it for a 40 pin connector in my phone.

I've never wanted to call a shop with a you tube question so bad before.
Have you ever done an a full explanation of the 1.05 volt power rail on a laptop and do you have to have a processor in place to fault find on the motherboard also what should be a typical resistance for this circuit. If you have done a video on this can you point me to it as I have a dell motherboard (09909-1 DG15MB 48.4HH01.011) that a repair shop stated was unrepairable after liquid damage even though the motherboard showed no obvious damage and am using it as a learning module for myself.
If you can put heat you can also use hotair to delay the solidification
Next lesson, please: replacing BGA (ball grid array) chip.
Thank you.
my question answered. thanks
Hello. Good video. Can you provide insights on what low melt solder you recommend and I presume your temperature is stated in degrees. ?

...ya know what? I'm not even surprised -_-
LOL
Great teacher thanks sir
All time best my idol 🤩💯👍🏼

THIS is an interesting topic.
If Low Melt solder melts around 100degrees (I assume this is celcius), can CPU melt it then?
Yes
