I have a LG Plasma Z-Sus 6871QZH060B that has a shorted IPM I have neverremoved one before. I Added some fresh solder to all the pins then tried my Denon SC-7000 solder sucker gun works. Not all the solder was removed from around the pins on the through hole eyelets. I then used flux and solderwickbut not all of its coming out from around the*pins.My*cutters will not reach under the heat sink to cut the pins to the IC. Some holes are clean others are not no matter what I try. I am not too proud to ask for help.

Re: Desoldering TV IPM Modules
Use a hair dryer or a heat gun on low setting to pre-heat the pins and solder. It's worked well for me: http://www.youtube.com/watch?v=Y8MNQYXw8E0Last edited by capkid; 12-13-2013, 12:20 AM.

I'm working on another Lenovo E14 gen 2 AMD here which has a ton of errors with the factory soldered DDR4 ram chips. I do have a donor board here from which I'd like to use the modules and swap them. Unfortunately, the modules are glued down with underfill, which i have never worked with before.
I tried with a lot of heat on the donor board but the modules won't come loose.
Are there any hint or tricks when it comes to dealing with underfilled chips/ic that could help here
Thanks

Hello everybody,
One of my friends brought me his brother's laptop to repair, I'm the third person who put the hands on this laptop (he tried to convince his brother to take it to me for the ram upgrade, dust cleanup and thermal paste replacement but he wanted to make it to his university friend... sorry if I say that, but we saw the result).
The laptop is a Lenovo IdeaPad Gaming 3 15ARH05 with AMD Ryzen CPU and Nvidia GPU.
I'm going to give a quick recap of what happened before I got this laptop for repair to make clear the situation.

Hello all,
Does anybody have a schematic and/or boardview of the Gigabyte GA-H110-D3A mainboard available? It would really help me out big time...
This board was donated to me in a known non-working state. In its previous life it was used as a mining board, so I suspected bad caps and a relatively easy fix. My intention is to use the fixed board as a testbed for a Truenas or Unraid build. The previous owner told me that the mainboard started to act 'weirdly' after replacing the originally installed Celeron for an i5-6400, varying from starting up irregularly to not at... -

Can someone recommend any good UV solder mask? But i need a solder mask that will stand high temperetures. The thing is...sometimes i have a bigger cooper ripped from the board, lets say mosfet pad... i reconstract it with cooper sheet, then i "glue it" with solder mask...then i use UV light...and let it cool a bit. After, i try to clean the cooper of extra solder mask..and till that part all is ok. But, when i use a soldering iron to solder that pad/cooper...the solder mask gets weaker or destroyed and finally the pad is ripped again from the board .
Is there any solder mask...
