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.

2, welding temperature curve is not correct, prone to Weld, solder balls become brittle as a result of long-

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.
