Hi guys
I'm pretty handy with a heat gun and consider myself quite skilled with a soldering iron
However a repair I am working on right now has me raising an eyebrow, or two.
It's a controller board of a 1Tb hard disk. The original one has a short circuit on the 12V rail that I have not been able to find. The owner wants to access the data on the drive.
I have a replacement working controller board (same make/model/revision) but I need to desolder the bios chip from the faulty board and use it to replace the bios ship on the good board.
Unfortunately the Bios chip is right near the SATA connector and I think that may melt during the rework process
The best idea I can come up with at the moment is:
1. Unsolder the Bios chip from the faulty board using the hot air gun.
2. Cut the legs of the Bios chip on the good replacement board near the body, then remove the legs from the PCB individually using my soldering iron.
3. Clean the PCB pads on the good board then solder the Bios chip taken from the faulty board using my soldering iron only and 60/40 solder.
Is that the way to do it without damaging the SATA connector or is there a better way?
Cheers
