Could somebody give me instructions how to solder computer chip on board?
I wouldn’t advise trying to solder a computer chip to your mobo. Most of the chips require you to lap solder the pins which are very close in proximity to each other lending the possibility of causing solder bridges. I hope you have a steady hand and the proper temperature on your iron which also has to be grounded to prevent any static discharge. Leave it to the professionals or get another mobo instead. All of the above is assuming you are talking about surface mount chips. Because most, if not all, mobos, are multi-layer boards and don’t have feed thru pins for computer chips or sockets. Improper heating from your iron can lift solder pads easily.
