* Finally, when soldered by hand, do the problem pads take solder? Yes, the XRF analysis will be interesting.

I have a customer with up to 8% scrap from one board supplier and 1% from another supplier for solder dewett and no wet over ENIG finish with mask defined pads. Initially I suspected mask residue on pads because of the no wets but I have come to find

Tenting a via refers to covering via with soldermask to enclose or skin over the opening. A via is a hole drilled into the PCB that allows multiple layers on the PCB to be connected to each other. A non tented via is just a via that is not covered with the soldermask layer. Leaving these vias exposed or covered has pros and cons depending on the your design and manufacturing requirements.

The evolution of soldering processes in the Microelectronics Industry has made a paradigm shift away from Sn/ Pb to Pb-free. Compounded with advancements in miniaturization, Pb- free soldering's higher re-flow temperature and the nature of solder has resulted in poor reliability relative to: mechanical strength of the solder joint, warpage and thermal cycling performance. In response, YINCAE engineered low temperature solder joint encapsulation adhesives.

Mid-chip solder balling is a defect typically associated with solder paste exhibiting poor hot slump and/or insufficient wetting during the reflow soldering process, resulting in paste flowing under the component or onto the solder resist. Once molten, this solder is compressed and forced to the side of the component, causing mid-chip solder balling.This paper documents the experimental work performed to further understand the impact on mid-chip solder balling from both the manufacturing process and the flux chemistry.
