FAQ:
Why bga can't solder on pcb?
There are two factors:
1. if Part of it can't solder, most likely that bga do not align with pcb perfectly.
2. if whole one can't solder, it is because heating temperature too low for it, you will need to raise temperature or prolong heating time.
What cause bubble on bga or pcb?
1.Moisture on pcb and bga will cause bubble when heating, so dry them with oven before soldering / desoldering.
2.Temperature too high for them can cause bubble as well. Lower temperature or shorten heating time.
Can solder ball reuse?
Solder balls should not be used again once they touch flux. Because they will easily stick together once touch flux.
