Whenever you are doing hot air rework you should always use flux. It does two things. First it takes to oxidation and keeps it off the outside layer of solder. This causes of solder to melt easier and evenly, it also keeps the oxidation from interfering with the welding process. Secondly it helps protect the components around it from the head. You can also use kapton tape to help with that. Also another big thing to consider while doing hot air rework is the flow of air. It doesn't matter if you melt a solder of the other components around it. Surface tension will keep them in position. Unless the air flow is too high then it will just blow off components. Start with a lower air flow and then work your way up. Also never run the repaired equipment while it's still hot. Give it a minute or two under a fan to cool down. Don't use a cryo spray either. They have their place, but in this situation it might crack the board

Great video but please be aware that you CANT go up in Capacitance rating, you CAN go up in the Voltage rating without issues tho. If you do go up in capacitance value your machine will start doing weird things or not work at all. Btw, great removal technique, I use the same myself but I use my desoldering gun to remove the excess solder from the pads, then apply flux with a Flux-Pen and then only put fresh solder on 1 pad per cap. After that, you can push down on the cap while heating the pad with your iron and achieve a flat installation. then you solder the other side and your friends will think your recap was done by a Pro. :-)

I need to mention that through hole caps can also leak in the same way SMD caps do. This is especially common with old Low ESR caps inside switching power supplies like thos inside classic macs. The output filter caps on my Macintosh Classic I PSU actually leaked that way and ruined the hole PSU; fixing this took me several moths, since I also had to replace many other components from that area that have been destroyed by the electrolyte. And removing this old electrolyte is crucial (especially in high impedance circuits, but also anywhere else) since it's - as the name suggests - conductive. You need to use acetic acid (from vinegar essence) to neutralize it; just dissolving it with alcohol or removing it with dry cotton swabs is not enough. Also don't forget to remove any residue of the acid once you're done, since it will quickly corrode stuff. And one other thing: the electrolyte leaking from caps sometimes is invisible without removing the cap, since it often stays under the bottom side of the cap or - with SMD caps - between the plastic part and the actual cap sealing.

Easiest way of removing electrolytic capacitors is to twist them while holding the boot (plastic base) in place. The boot will break the legs out of the capacitor, not off the board. Then use copper solder braid to clean the pads off completely. Finally, apply flux to the pads, hold the new capacitor in place and tack-solder its legs onto the pads. This prevents excess solder from spreading underneath the capacitor boot and bridging the vias underneath or nearby the capacitor.

I had to replace an intel I/O chip on a mac mini once, I had never attempted it before but it wasn't too bad, I did have to use an oven to properly flow the chip which did work. I also had to replace two or three smd capacitors on the same board after baking. That late 2008 non working mac mini that I bought for only $30 over 3 years ago still works to this day! I find that if you do not have very fine solder ".5 mm or thinner" than just applying some solder paste to the pads and laying either the component or capacitor in place and quickly melting one side with a fine tip soldering iron is not too hard. Dental composite instruments can really help put the paste where you intend and solder paste leaves such a clean joint! But I have spent quite a few years repairing car audio equipment and have worked on many smd based amplifiers, so I was ready for the mac min! Another tip would be to buy a mixed lot of the capacitors where the ones you need are included, that way you can use the others for recapping or repairs.

You want the same capacitance when replacing the caps. Higher voltage ratings are fine though. Do yourself a favor and remove all solder from the pads before you install the new caps.

@@_derSammler Check out the chart in Afrotechmods' video called "Why electrolytic capacitors are actually kinda shitty 💩" While it's true that tants are much closer to AL electrolytics than the other types on the chart, the tants are still closer to every other type than they are to aluminum electrolytics. Let's say that your circuit was designed around the expected ESR and ESL of an AL electrolytic cap and then you throw a tantalum cap in there instead. Now the ESR and ESL have changed in a circuit expecting a certain ESR and ESL. The rest of the circuit doesn't get reengineered to compensate so inductance and resistance-sensitive parts of the circuit are potentially out of spec. If you are engineering the circuit for better long-term reliability then tants are the way to go but it's almost always best to stick with whatever the designer intended when servicing the caps in something else.

You yourself listed examples where it is not OK. Speaking of doing this for 30 years: you can’t just go up on every cap in an Atari 5200 or Commodore 64 for the same reason... those analog inputs use the pot with capacitors to adjust the frequency and determine position. I’ve taken advantage of this to repair new-old stock controllers where the resistance has dropped in the pots over time. Funny that you say it that way, “Electronics 101.” ;) The first thing he says is that it isn’t taught in school. Granted, the comments section is full of people saying otherwise." Emmett, fair enough, I agree that there's times when you shouldn't modify the rating and values of components. certainly in timing, and filtering circuits, as well as op-amp gain structures, etc... but in run-of-the-mill-bypass caps... no harm done. truth! you must learn the rules, and then discover when it is ok, to bend them a bit in the sake of immediacy...

I've recapped many of these, and other stereo equipment, and when I watch these videos I cringe a bit because you don't need to mess about with solder stations or hot air guns. It's not at art project! Just take a set of clippers and snip the top of the cap. Once you crush it, it will slide off easly exposing the pins. Then just lift off the plastic base over the pins, leading just the pins standing. You can then remove these really easily by heating them one by one with the iron and using a pair of pliers to pull them off the PCB. You generally don't even need to tin (re solder) the base before inserting a new cap. Just clean off the electrolyte. I've never broken a pad and I don't use flux - modern lead free solder has it already - and I use a cheap iron and solder remover gun. Also, don't replace SMD caps with newer SMDs. Just get cheap electrolytics. Much easier to work with and replace in future, if required. Tantalum caps are also a waste of money. Don't over think it!

Please be gentle when pulling up on those aluminum electrolytic capacitors from the board Sir. Those pads come off with very little ease. Much more so on older electronics, that have leaked electrolyte all over them. I saw you tug on one of those capacitors. You are gonna rip the pad off of the board, if you do that. I made that mistake with my NEC Turbo Duo game system, and probably depreciated its value by making such a terrible move on one capacitor mounting location. I had to find an alternate path to solder it to. Not only that, It was a real chore, to find a way to mount it securely to the board. Don't be afraid to get the hot air close to the board with one hand, and some tweezers with the other hand. Hold the capacitor you want to remove with the tweezers, and very gingerly, lift up on it, then apply the hot air moving back and fourth, as the hot air is gonna work its magic, melting the solder. The capacitor will come right off with very little effort.
