Why are the solder joints sharpened during PCBA processing?
The factors caused by the sharpening of the solder joints may be that during manual soldering, the soldering iron tip on the operator's hand is removed prematurely when the solder is not completely melted and fixed. The second is that the temperature during soldering is too low. But most of the reasons are that the flame iron head is removed too late, the welding time is too long, and the flux is vaporized, that is to say, the drawing tip is related to temperature and operation.
BQC think that the solution to this problem is: the welding time should not be too long. Once the phenomenon of sharpening occurs, it is only necessary to add flux and re-solder. In automatic welding, attention should be paid to the angle of the printed circuit board leaving the solder liquid level. Shenzhen BQC has specialized in PCBA processing for many years.
