Visual inspection criteria for are: - Flat surfaces, top and bottom (especially no convex doming - difficult to achieve if boards are HASL finished, but not impossible). - Surfaces flush with the rest of the board. - Good plating adhesion over the top. - No apparent shrinkage from the hole sides. Our boards are subject to vibration testing, so we examine boards for any cracking of the epoxy-filling.

Besides the cross-sectional, thermal-shock, etc etc....what are some other tests performed on this type feature???
