Any hints/tips for removing a 5x5 ball grid array chip?
Removed in good order for re-use that is . No specialised tools available
and I'm not going out to buy any for a once in a year job. I have a few ideas but have never had to do it in earnest before. There is about 0.05 mm clearance space between the balls under the chip and about 5 x 5mm in size. A few minor SM can be removed from the opposite face of the board, multilayer and about 1mm thick |
