Tips on how to start with microsoldering

Hello,

I am looking forward to learn microsoldering as I already have some experience with replacing iPhone parts and that would give me completely new opportunities. First of all, I know this isn't a thing you can master within a day or something but I'm really willing to learn it and prepared to spend weeks and months doing so.

Equipment-wise there are some sites on the internet that offer guides on which equipment is the best and what to pay attention to, so that's not the problem. But to practice the skill I really don't want to use intact logic boards as I'm sure I will burn a few at the beginning. So I would like to know if you can tell me if there is a good source to get damaged logic boards from? On eBay for example I didn't find much and the one I found also was kind of expensive (25€).

And the second question would be, if I work with damaged logic boards, how do I see if I'm doing the right thing? I mean I wouldn't recognize if I'm damaging it even more as it was already damaged before... Or are you able to see from the outside if you damaged the logic board, like obvious burned IC's or something?

Thanks in advance!

@vorsichtkarsten my suggestion would be to get tools that you are comfortable with. Everybody has their own technique and does things a bit different. I have seen people do amazing repairs with a department store soldering iron and a wrapped around copper wire to create a J-tip. If you are planning on doing a lot of repairs, stick with brands that will be around for a while. Those are companies like Hakko and Weller, that way you have some parts and supply support for later on. iFixit has some great tools https://www.ifixit.com/Store/Tools/all?d...=on|on here] I still use an inexpensive Aoyue rework station and separate soldering station. Are the temperatures always accurate? Probably not, but I use an external thermometer to verify. Same goes for my IR rework station and various other tools. So, I found a workaround to get my repairs to last. The importance is that those tools work for me, even so they may not work for you or anyone else. My advise, find the tools that work for you. Whatever brand you choose, I would suggest a soldering station, hot air rework station, Hot tweezers and definitely a magnifying source (Microscope etc.). The parts you do not want to take shortcuts on are the solder, solder paste and good flux. Remember, I am just a hobbyist and do not make a living with that. You most likely will get a different answer from the "Pro's" on here. you cannot learn how to solder by watching youtube videos. You will have to go out there collect all kinds of old boards and practice, practice, practice.

The only way to know if your soldering worked, is when your board works again. You will need schematics, the ability to understand those, board layouts for those boards and at least a decent multimeter. This is just to get started to test boards for short circuits and failed components.
