    How to correctly desolder through hole IC?

    Hi!

    I tried to desolder through I had IC that I wanted to replace but failed. And now I came here to learn what's the correct way for doing this. I tried to use soldering wick but the capillary force kept solder in the hole. With soldering wick I only managed to remove the part of solder that was outside the hole. But the solder that was inside the hole never got out. And of course when I moved on to next pin the solder in previous hole hardened again so no matter how many times I did all the pins there was still solder in holes.

    Question 1: what would have been correct way of desoldering this IC?
    Question 2: I tried to pull the IC with pliers while heating the pins from the other side but it did not help either. And as a result, I now have some pins stuck in hole together with solder that came off from IC when I pulled it. what would be correct way to remove these?

      Guide to transplant MEC1503 EC chip and EEPROM reprogamming for T14s gen 2 and X13 gen 2
      by acedogblast
      This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.

      There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as...

      Best way to solder LVDS connector for beginner (and qfn) ?
      by corrize
      Hello, I'm a beginner for micro soldering. Right now I have some difficult to solder a qfn 20, I guess I put too much solder on the thermal-ground pad, the result is a corner of chip wich don't touch the board (last try).

      I use a wire solder with hot air, I tin the board and chip before with iron and I use good flux.

      I will have to solder a LVDS connector (40 pins, laptop pc), I saw a solder paste in seringe, good quality (it does not scatter).
      See the test :

      UV solder mask - high temp resistent, recomendation?
      by myth77
      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...

      BGA solder balls not connecting - help pls
      by petemanuk
      So I though in my spare time I’d set myself up repairing motherboards mainly pin damaged lga1151 sockets types.

      I’m using an achi ir sc pro rework station (gave up on my Achie ir6500 - don’t recommend)

      I’ve managed to get my rework profile somewhere in the correct region (after a lot of trial and error) to get the old sockets off and reflow new ones back on again, the problems I’m getting is not all of the solder balls are re-attaching when re-flow occurs. I know this because when socket is removed pads still look clean and have no solder...
