Hi Netters,

This is a question about assemblies being repaired because through holes are
damaged.

In IPC 7721, method 5.1 (no inner layer connection):

Should a jumper (or jumpers)be used to insure reliable electrical
conductivity for class 2 assemblies?
     How about class 3?

How about for method 5.2 (with inner layer connection)?

Thanks in advance for all answers,
