Kevin,
Pls also consider whether there is some contaminant to dissolve from board
into the flux tank. For example, silicon-containing compounds may inhibit
the foaming properties of the flux

All,
我们公司最近波烽焊工序出了点问题,就是松香不能正常发泡,表现为松香在刚开始
使用的时候发泡很正常,但用了一两个小时之后发泡就不均匀、发泡很大.异致PCB板
经过预热后松香不能很好的挥发,残余松香附在触点上,后工序出现高不良.
请问如何解决此问题?如果分析松香是否有问题,可以从哪些方面入手?
Best regards,
Kevin Liang 梁益健
