Pad cratering is a mechanically induced fracture in the resin between copper foil and outermost layer of fiberglass of a printed circuit board (PCB). It may be within the resin or at the resin to fiberglass interface. Do you have ever problems about pcb pads? please talk here.

Not all but some new boards we have had solder joint problems, for example some of the pads refuse to solder at all and the solder paste ends up attached only to the leg, reworking makes no difference and a variety of fluxes have failed. How can some high volume production boards work fine and these prototypes fail so badly. Can anyone offer an explanation?
