    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!

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!

      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! @@Happyguy60

    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.

    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.

    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.

    • @LearnElectronicsRepair
      @LearnElectronicsRepair  Рік тому

      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.

    • @Ghost572
      @Ghost572 Рік тому +1

      @@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.

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.
