    My fave soldering station now is the Yihua 982. I bought it with the C210 handle and then bought the c245 handle and tips set for both. I use the c 245. It is very fast at heating up and goes to 200c when the handle placed in the rest. I have a few T12 kits and plenty of tips, few different displays for the T12 tips, Parkside soldering station which I bought off ebay for next to nothing as it didnt have a tip and a Draper soldering station too. I have the cheap 5w USB iron and also the TS101 portable with extra tiups and dont use it. I tinned it and made a case storage for it but never used it..

      I've seen the 982. It looks pretty good. Ill be the first to admit I'm a bit of a Yihua fan. Everything I've had of theirs has worked really well, apart from issues with the iron which has been down to the generic tips I bought for it. I think for the price, they do some great stuff. But then again, I don't have any expensive stuff to compare with. That said, they do the job 😊

      @@RetroComputingReboot Those type of irens you have are veery slow at heating up. Thge Yihua 982 with the JBC style tips heat up around 5 - 6 seconds and ready to start soldering. I found hte cheap T12 irons are quick heaters and plenty of styles of tips. I have made a few of the kits and 3d printed cases for them instead of buying them. They are cheap, reliable and good to use. But, the Yihua 982 has to be my fave now. I had 3 of the T12's set up on a shelf and always had my goto one and didnt use the others at all. I taught myself to solder as I couldnt if it meant it would save my life before. I found out by error how to make sure a tip was clean, tin it before putting the tip to a piece then applying the wire. I could solder printed boards, but I couldnt tin wire. I was doing it wrong or not manage at all. Now with the 982, I am finding it easy. I have a tube of flux but hardly use it. I have a lot of soldering wire that I bought from China, supposed ot be flux cored, but haedly any flux in it, and I have my goto wire which is silverline. Cheap, but has good flux core and leaded.

      @ianallen2 I do fancy a 982. I think in reality though it would wipe out my budget for these vids for some time. But who knows, I love new stuff 😂
      There's a certain joy to soldering when it goes well. It's one of them things that seems incredibly simple, which it sort of is, but there is a real skill to it that I'm still learning to master 😊

    On the second leg of the transistor you got too fast on the third leg moving the second leg while it was solidifying, making the second solderjoint brittle.
    Also try to work faster, adding a little more solder the first time.
    To not overheat the component, apply a 4 second rule max. of soldering the joint. You can, for example, place multiple components and switch between every leg soldered to give the component time to cool.
    Furthermore, 360 degree celcius is way too hot. Check the specs of the solder and look at the size of the pads/tracks. You might need a little higher temperature only when the groundplane is very large.

  • @philipburrows
    @philipburrows 7 месяцев назад +1

    You could try the cheap solder on the hotter temperature and see how it flows, because a lot of cheap solder acts like lead free solder where a hotter iron is needed to get a good solder joint.
    On the iron itself measure the heating elements outer diameter and get tips with the inner diameter is nearest to the diameter of the heating elements outer diameter.

    • @RetroComputingReboot
      @RetroComputingReboot  7 месяцев назад

      I went for upping the temperature and it literally obliterated the tips in a relatively short period of time. Wasn't a good feeling either.
      As for the tips, it's not that simple. Getting that sort of info isn't that easy and I doubt the manufacturing tolerances would be as tight as perhaps a Hakko. I don't know though as I've never had a Hakko or similar, but I'd expect so

    The problem with the cheap solder on ebay & amazon is that you can never know if it's what it says it is! I have seen solder advertised on amazon as "60/40 lead free" - which is an oxymoron! I use the loctite multicore crystal 400 (60/40 3% 'no clean' flux) stuff available from CPC/Farnell in the UK as well as Mouser and the like for reasonable price, and can't remember the last time I used external flux during soldering! I had the same epiphany as you coming from a cheap lead free reel. It really is night & day both in terms of ease and the nice shiny result. Welcome to soldering nirvana :)

  • @stevenbliss989
    @stevenbliss989 7 месяцев назад +2

    The trick is to NOT NOT NOT put the solder onto the tip,
    ...put it on the pad and wire at the same time (mostly, with some ever so SLIGHTLY and SHORTLY touching the tip to start the melt & heat transfer cycle).

    Something to bear in mind regarding the soft drink can shims: They are coated on both sides - outside with paint/print, and inside with a thin coating of plastic to act as a barrier between the often acidic drink and the metal of the can. If you can't source any un-coated metal to use as a shim, give both sides a brush with a wire wheel in a Dremel to get rid of a source of fumes and potential damage to the iron's heating element.

    @zx85 7 месяцев назад +1

    I never gave the solder I use a second thought, mainly because I got it well over 20 years ago - probably from Maplin. When the reel finally runs out you can be sure I'll follow your advice - something so core ('scuse the pun!) to working on electronics deserves to be an investment 👍🏻⭐

    • @RetroComputingReboot
      @RetroComputingReboot  7 месяцев назад

      Honestly James, it blew me away the difference. I've always gone super cheap with the solder and as such never appreciated the benefits of the good stuff. I'm not even adding flux now!
      The irony is there's loads of comments on the web stating to use good solder, I just chose to muddle on.
      When you work to a budget, there's always compromises to be made, but for me from now on this isn't one of them. I'll get myself a big reel of this at some point. I just don't know what to do with this big reel of cheap stuff 😂
      I found it interesting too on all the advice out there on temperature to use for the iron. I'm going to run at 360 C for a while and see how that works. The shim seems to be doing well at keeping the heat in the iron but I can see issues with that longer term, but it's nothing I can't manage, it's just going to make tip swapping more awkward. But that said, I very very rarely change the tip anyway 😊

Or maybe they can divulge the great secret of who this distributor is? But if you can't be bothered with any of this you can get fakes real cheap on aliexpress. Everything on the Internet is going to be fake. Amazon, ebay, ali, all of that is fake. £5 it's definitely a fake. Too much for a fake too. It should be more like £2 Real ones if you can get them are going to be at least £10 is my guess. Because real ones are $7.75 USD You got VAT and what have you. You're going to pay more there.

      I've definitely used the BC3 tips. They have worked quite well for me when I have but for reasons I can't really explain, I've gravitated to a preference of the chisel tip 😂

    • @brianparr988
      @brianparr988 7 месяцев назад

      Yes, exactly. I find you can get closer to the joint because of the sharper angle. I prefer a BC3 because it's thicker, offering more thermal mass, and doesn't lose it's temperature to the board as quickly. As you are probably aware, ground plane joints can be troublesome in this regard.

    • @RetroComputingReboot
      @RetroComputingReboot  7 месяцев назад +1

      @brianparr988 I have tried the BC3's for stuff on ground planes and I totally agree they work much better for that. Its just a pain swapping over the tips as it's just usually one or two joints I need to to so being lazy I usually just struggle with a chisel tip 😂.

    Depending on the circuit, just the 15pF on their own might be fine.

    • @stevenbliss989
      @stevenbliss989 7 месяцев назад +2

      REMEMBER, all parts have a tolerance! If the cap are 5%, that is +/- 0.8pF, i.e. 15.2pF to 16.8pF range! If it's 10% double that range!
      VERY FEW circuits require caps in high precision, so again, I suspect that regular 15pF could be fine.

    • @RetroComputingReboot
      @RetroComputingReboot  7 месяцев назад

      In most cases I'd agree. However, the specs were for 16pf on a 5% tolerance. Using a 15 pf would be outside this. Especially bearing in mind the tolerance is plus or minus, so with the 15, that could pull the value even lower

    You can get quite good cheap solder but it's definitely hit and miss, you need to test it to make sure it's good, you can usually tell by the amount of flux residue it leaves behind and the melting point.
    Also directly heated soldering irons like JBC T245 clones are miles better, no need to muck around trying to get good heater to tip contact it just works, you get near instant heating and can easily swap tips in seconds.

    What I'm seeing is you're feeding the solder to the iron tip. That's not good. The iron is just there to heat up the joint. You're soldering the joint. So you feed the solder to the joint. Solder goes to heat. Just what it does. You have the iron on one side of the joint and you apply solder to the other side of the joint. Try it. Really if you're practicing heat control you really don't even put the solder tip on the part lead. You heat the pad and let the solder wick the joint. Just don't feed the tip. If you do the solder will just ball up on the tip. You want the solder on the joint. So that's where you have to put the solder. Sometimes you have to feed the tip a little to wet it for heat conduction. But mostly you're going to be feeding the joint.
