BGA rework common problems
BGA rework common problems:
1, the maximum soldering temperature is not correct, Weld too low, too high even welding a short circuit
or even burn important original IC, chips.

term reliability is not high results.
3, hot air soldering, it may damage the motherboard components around, causing malfunction was extended.
4, small capacitors resistors and other components on the motherboard heat off, resulting in an incomplete
circuit board, resulting in malfunction was extended.
