This sounds a lot like a profile that is killing flux activity prior to wave immersion. What is your topside preheat temp just prior to hitting the wave? What type of preheat do you have, convection or radiant? Are you using a chip/turbulent wave

I have another question: Does the slope of the conveyor is an important parameter in the solder joint quality? What is the standard in degree? Does that parameter can resolve my problem of partial fulling hole (between 50 and 75%)?

Actually we're using ALPHA METAL Vaculoy 63SN/37Pb solder bars in our WAVE (ELECTROVERT ULTRAPACK 650C). With that solder, we use the ALPHA METAL LONCO SLS 65C flux. With this combination, we have many bridges and sometimes, the solder do not full co

When using high tin solder, doesn't proper specing to avoid the effects of tin whiskers become at least as large an issue as proper specing for defect-free wave solder processing?

Dave: You should see a solder smudge on the gold plating where the ball was attached, if there is (was) solder reflow during either the (1) BGA fabrication, (2) your BGA attach, and / or (3) your BGA removal. You rework will not remove the solder

IR reflow worked well for leaded solders but is not recommended for lead free reflow soldering. Your darker components (ICs) absorb more heat from IR than lighter colored ones (Rs & Cs). When getting all solder joints up to the proper lead free pea

Intermetalic Layer (IL). A compound formed at the interface of two different metals, whose atoms have an extremely high natural attraction for each other, so high, that they do not bond to other elements by any other means. Also, intermetalic compo
