> We are experiencing a strange failure in a circuit board and I hope
> someone can point out the failure mechanism.
> The boards in question fail with trace opens when cold, heat the pin with
> an iron and the open trace reconnects. The boards in question are 0.093"
> thick Getek, 6 layers (4 rout - 2 planes), with 0.015" trace and 0.010"
> spacing (we ain't talkin' high tech here :<) ). We have sectioned the
> holes in question and see really clean plating and pad junctions, no smear
> or nai-heading. Any suggestions as to cause?
