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.

After designing my custom PCB at first time,I've found a problem suddently.Some pads overlap on the PCB and become a large pad. I wonder whether I've made a mistake or not. If not, can I assert that it is just max tolerances?
