Unless this can be tracked down to to the same via on all PCB's with a mechanical process flaw, it is difficult to find all the bad or about to fail vias. 2. it is possible to run a jumper wire but if the cause is bad plating or fractured vias, it will not work Best course of action is to salvage the 2 expensive parts, if possible. ______________________________________________________________________ This email has been scanned by the Symantec Email Security.cloud service.
