  • ECU de-soldering problems...

    hey guys, whats up? this probably doesnt go here, but i figured this forum gets looked at more than the others and i kind of need help fast. anyways, i was trying to de-solder the chip from my ecu to socket it, and first found that the chip was soldered top and bottom. so after we got all the solder out the damn thing wouldnt come out, it wouldnt even move. i tried sliding a piece of paper under it to find out that it had been glued from the factory. anyone else have had this problem?

    If you are sure you got the solder off of both side and the hole then its just the glue. You can carefully and slowly pull the chip off the board. It makes it much easier if you heat it up with a air dryer or heat gun to soften the glue. Just be absolutely sure the pins are free and not being held in by any remaining solder. IF you dont get them free they could take a trace with them and that sucks.

      Use toluene or xylene to disolve the coating on the board. It works quite well.

        thanx guys, after making sure all the solder was out and still not being able to pull it, i got my dremel and cut all the legs out and slowly pryed it out.

          It is not recommended to confirm proper installation by driving into walls or other barriers as this could cause personal injury or damage to the vehicle.

            That works too. I did that once and it worked quite well, but I was always afraid of hitting the PCB and cutting some traces.
