I train people to solder and have for 25 years, very good technique. One tip for you; if you use solder paste for the whole assembly you can re-flow small boards on a hot plate. This is a very effective method and I have used it many times for building voltage controlled oscillators and other sub assemblies that solder to a larger PCB. Preheat a piece of 1/8" thick aluminium sheet to hold the part being soldered and remove it with the part, this will slow cooling and prevent thermal shock to the components. Multiplayer ceramic chip capacitors are particularly sensitive to thermal shock.

IC socket is also subject of poor contact due oxidation (simple pull out and put back in works but it would require to open a case of the device). Beyond oxidation issue the socket has a price and on mass production it could come to million dollars extra cost.

Huge Kudos to the youtube algo for putting this in my list!! As a newb hardware junky (software and trad IT all my life) learning the ins and outs of soldering is top of my list! I soldered my first thing last week, oled to a four pin header for a custom raspberry pi case. Before doing so, I soldered two wires together... The big win for me? The board came with a straight four pin header. I didn't like the real estate in the case so I wanted a four pin with an angle (45? 90? I suck at degrees, so yeah, bent). I had a box of components, one was ultrasonic, had the header I needed so? I desoldered it, and soldered it to the OLED! WORKED LIKE A CHARM! Best part was my lead wires then ran down the wall of the case to the GPIO on the pi! Such a cool thing! Anyhow, last Kudos to you. GREAT CONTENT AND YOU ALWAYS TEACH ME SO MUCH! THANK YOU!

Yeah and would REALLY suggest using hot air (or skillet/hot plate type heater) for QFN parts, although not killing things does take some (lots and lots and lots of) practice. Its far too easy to miss align something with a 0.5mm pin pitch but if you get it all up to temp the liquid solder's surface tension will pull the part into the right place if the pads are correct. As for getting it up to temp with hot air, a pcb will dump a lot of heat into any surface its placed on, an air gap will help this a little.

You should never bend a pin more than you have to. Repeated bending stresses the metal and can cause failure. Besides, in a manufacturing setting, you would want proof that you clinched it.

Yeah, it was an old Dell tablet which the repair shop had given up on, so I think it was worth the lesson that some components might melt under the hot air station, but it could still have been avoided if I had seen this video beforehand. A micro-USB port was probably also the wrong part to start with considering the amount of pins it has so tightly together, a smd resistor or a full size USB port would probably have been an easier place to star.
@Firecul
@Firecul 6 років тому
Yeah micro usb really isn't the easiest to start on. I actually gave up reattaching a socket a few years ago, I just soldered the wire straight on to the pcb. I only got away with that because the wire was thicker than the gap normally taken by the socket so functioned as a pretty effective strain relief. I actually reused the socket to test phone chargers after I soldered some wires to the pads on the bottom of the socket.

My two cents on the matter: -To solder TQFP, I think it's easier to put a little bit of solder on one pin, then pull the excess on the other pins on the same side with the tip of the soldering iron. If there isn't enough solder for all one side, just add a little bit more, and pull it again until you're satisfied with the result. And if there's too much solder, remove all the solder from your soldering iron, then use the tip to remove a little bit of solder from the pins. Just repeat until the excess is gone! -For SMDs with only two leads, like resistors and capacitors, you can impress your friends by using two irons at the same time! Put a little bit of solder on both the solder pads, put your component roughly in place, then melt both solder pads at the same time, with one iron in each hand. The component should magically align without doing anything more! It sounds like it's quite hard to do, but to me, it's waaay easier and faster than placing the components by hand. You can just add solder to all the pads, put every component vaguely in place, and then perfectly solder dozens of components in a minute!

The most important thing to realize with soldering is that it's not about smearing the solder into place, but about letting surface tension do the job for you. That's why even a huge solder iron tip can handle much smaller SMD components fine. The surface tension will even center SMD components for you on the pads.

Camera-based microscopes are cheap, but a pain to work with. There's always a significant delay so when you need to move something, it's hard to tell when you need to stop moving it until it's too late. And a single-lens microscope has no depth perception, making it hard to position your tools where you want them. Use a camera-based one when you want to examine an item or show it off to others, but use an optical (preferably stereo) if you need to actually work on what you're looking at.

Solder with flux core/fluxfree solder: some solder (duh, word repetition) have tiny channels inside them which contain flux (usually rosin). It helps in cleaning the soldered area and making a solder joint all the better. Flux-free solder doesn't have this; it requires the flux to be applied prior to soldering. (I imagine it may be useful where the PCB/components call for a definite/special type of flux. Practically useless in the DIY universe, but I'd be happy to be proven wrong :) )

Tell the good folks about bad soldering product. 90% of solder and flux is garbage from China. Here's how you will know: Every soldering iron including fixed temperature irons are hot enough to melt solder. If you can't melt fresh solder from the spool/coil then toss that solder into the trash immediately. Never overheat the tip just to melt solder, 300 degrees is more than enough. Too hot will destroy the stainless finish and it will begin to oxidize. An oxidized tip will not hold solder. Keep tips clean and always tin it. If you melt solder and it balls up and doesn't stick even with flux on a good tip, it is garbage solder. Toss it into the garbage. Never try to work with that crap. Many components out there use garbage solder. If you're trying to desolder and it won't melt, simply clean the area with alcohol, add flux, then melt fresh good solder on top of the old solder until it melts everything, then suction it away. Don't bother with braid, it will not absorb garbage solder. When in doubt, use leaded solder whenever possible. Give the folks some links to the best solder and flux.

Thanks for the advice on the braid, I tried desoldering an 11 pin coil from an old PCB using wick, adding flux and proper solder didn't help the wick absorb the remaining old solder. You can imagine how long that took. I disagree with the 300 degrees you mentioned though. In my experience it is often worthwhile to go to about 320/330 Celcius to increase the flow of the tin and flux. It is often preferable to introduce a little more heat for a shorter time instead of the other way around.

First of, Lead is toxic, it will make your brain mush and stoopid Always wash your hands and don't eat and solder, and when working with flux, don't breath the flux, or else you'l get asthma over longer periods, not even if it smells nice, get a fan with a well ventilated room or cleaning system and blow the fumes away. In any case, in case anyone comes across my comment and you are looking for good solder, look for things such as: Sn63Pb37 "63%Tin 37%Lead": This alloy is a eutectic mixture, so it will melt a lower temperatures (185 Celcius or 365 Farenheit) than any other tin alloy, is easier to work with, as it melts faster and solidifies all at once, which keeps your boards and tips good for longer (as lower heat at a shorter time is better) and gives you shinier and prettier and stronger joints. Sn62Pb36Ag2 "62%Tin 36%Lead 2%Silver": This is probably the "best" alloy you can find, it is also a eutectic alloy mixture and has a slightly lower melting point than Sn63Pb37 and can make better and stronger joints, but to be fair, the big difference in price (you are gonna pay a *lot* ) and the small difference in result when you do soldering good (bad technique ruins everything), makes it in My opinion not worth it compared to Sn63Pb37 for 'general' use. Sn60Pb40 (60%Tin 40% Lead): The 'standard' solder you are probably gonna find the most, it is a good alloy, it is cheap and you can do jobs with it and will be fine, melting temperature is higher (190-200 Celcius or 374-392 Farenheit) than Sn63Pb37 and is slightly harder to work with since it may needs longer to melt, which may be less good for your board and it solidifies slower, which may give you less shiny and slightly weaker joints, Sn60Pb40 is absolutely not bad, but just get Sn63Pb37, it's better and easier to work with. Sn99.3Cu0.7 (99.3%Tin 0.7%Copper) or Sn96.5Ag3Cu0.5 (96.5%Tin 3%Silver 0.5%Copper) Now something you need to know, in some places like EU, the use of lead is forbidden in production and most local shops and some online probably won't sell solder containing lead. This has to do with environmental reasons and the fact lead is very toxic and destroys your brain (you not OK, reatard? i am wood. stupid) if you it gets in your body (Just *Properly* wash your hands Everytime and don't eat and solder and clean everything the solder and your dirty hands touched). Lead-Free is may be harder for beginners to work with since it's harder to make good joints as you need higher temperatures and it melts slower and solidifies slower, which is worse for board, your tip and the flux fumes will stink worse (just always get a fan or cleaning system to blow away fumes, breathing it in is never good for you and can get you asthma at some point). However Lead-Free solder is not bad, with the right technique, you can make good joints as good as leaded solder, you should use good flux whenever possible, as it removes oxide and makes all solder flow better and cleaner and shinier. Though, you can't mix leaded and lead-free solder, doing so will make bad contacts, if that is the case, just clean the contacts and reapply the solder. Lastly, compared to leaded solder, your joints may get issues like Tin Wiskers over the years. Anyway, for good or the best brands you want to go to, look for Kester, that is arguably the best brand and everyone's first choice when possible. Otherwise Multicore or MG Chemical are also good brands I heard. You can purchase these from big distributers like Digikey, Farnell, Mouser, Amazon, etc. For the easiest to work with solder that gives you awesome joints (granted use it safely when it contains lead, as that stuff is very toxic), look for Kester type 44 or 275. The difference is the flux type used, flux helps remove oxide, which helps bind solder better and gives you much better joints. 275 is no-clean flux, which doesn't Eat/Corrode your board if you leave, doesn't mess up conducting of components, thus doesn't 'need' cleaning, but dirt and dust may stick and make your joints look nasty, it is also much harder to clean, especially after you leave it after it too long 44 is Rosin Core, this gives is easier to clean than 275 and is top notch at removing oxide and helping you achieving shinies, but you must clean all flux leftover with isopropyl or flux remover, as when you leave it, it Will eat/corrode your board and may mess up conducting of contacts. For Lead-Free that is easy to work with and give you good results, look for Sn96.5Ag3Cu0.5, for leaded look for Sn63Pb37. And when soldering, you may need to set your temperatures little higher, as melting temp when hand soldering may differ, but don't set it too high, as you burn the flux and get more bad fumes, more easily damage the board and ruin your tips faster. Hope you find this useful, for more resources, look for Louis Rossman and watch at Great Scotts video's Also look around 'reddit.com/r/soldering/'.

Flooding all of the QFP pins with solder, then using solder wick is not ideal for overheating the chip. With a dab of flux, decent soldering station / tip, and finer solder, it's really not that hard to quickly solder each pin, even on those small TQFP chips. Or, use a "hoof" style tip, and drag-soldering technique. Best not to dwell the heat onto the pins for too long, especially with the mass of a big blob of solder.
@electronash
@electronash 6 років тому
For QFN chips though - yeah, they suck. lol I had to solder one the other week which had a thermal pad underneath. I used regular solder, but added a tiny bit too much to the thermal pad on the PCB, so the chip sat slightly above the pads on one corner. I had to redo it, but it was OK after. You can reflow the pads around the edge with the right sized chisel tip though, or a pointy hook tip. (which is the tip of choice for Louis Rossmann. You don't necessarily need quite as much flux as he uses, but hey, it works. lol)
@ianmontgomery7534
@ianmontgomery7534 4 роки тому
It shouldn't if you use a wave tip as the heat is is over three or four pins at a time and you shouldn't need any wick. It is fairly common practise to drag solder these chips.

be careful when wicking the TQFP not to apply too much pressure or you are going to bend your pin, i did it once on a processor chip with a very small pin pitch on a LCD TV motherboard, then it broke off and its a disaster to fix

I once forgot to use flux, and my solder got dry. Then, I remembered how you said that flux makes sure that solder only sticks to the iron, lead or pad. So I pulled out my flux (which already hardened but melted when I heated it with my iron) and used it well.
@captainweird1822
@captainweird1822 5 років тому
A little helpfull tip, if you have multiple parts you want to solder at once, bending the wires to hold it to the board while you solder can get messy. Use blue tack on the other side of the board to hold them. That’s what I do and so far it’s never failed me, just make sure not to touch it directly with the iron :)
