| Can anyone tell me if there is a reference for smt component height specs on the bottom side of a board, which will also go through wave soldering. A current design I am reviewing has tant caps(7343) and a crystal on the back side. Should I only b

Does anybody know if a contraption exists that will minimize a PCB's tendency to become slightly bent after reflow? We have a new product that we're planning to assemble in a couple of months. The board is 9.7" by 13.4" and it is imperitive that we

| Does anyone out there can let me know how to clean a Entek Coating Board if I have a misprint during solder paste printing? According to the guys at Enthone, squeegee most of the paste off, then use Kyzen Lonox (which only removes 3% of the coating

Our experience has been that mechanical crack occur vertically through the chip. In other words perpendicular to the board surface. You can sometimes tell through close inspection that the crack may have propogated from a point that the nozzle may
