Quoted from spikedbat:Well I'm not super comfortable but I was able to replace U18 last night. Had a little warm up soldering tutorial on replacing a header on another DE power supply. IC removal is not easy. At elast for me it wasn't. .....
DE Power Suplly is NOT a WPC CPU-Board!!!!
As said by homepin, let it be, if you have not enough experience, the traces on the WPC CPU-Board are soooo delicate, that you can destroy more than you think.
Homepin recommends using wick or a good solder sucker, BUT homepin is an absolut expert and he knows how to work with wick and a sucker.
I have seen many boards, where people with little experience destroyed the board by using a sucker (I have seen suckers, that were too strong and suck away the pad) or solder wick (often poeple work too hot and the pad is gone).
If you do not have a HAKKO 808 desoldering gun, I always recommend people with not so much soldering experience, to use the "needle-method" with a 0,8mm needle from your pharmacy. Imho, this is the most safe way, if you do not have the proper tools.
I have made a few years ago 2 videos, where I showed this way. Most importent is fresh solder!!!! And not too much heat!!!
And do not work in such a hurry I worked in my video, I only made this for demonstration purposes in an absolut hurry and my children were playing in the background
And remember: FRESH SOLDER!!!!!!!!
