IPC guy,

What is the appropriate electrical test voltage values for;
Commercial?
Mil?

What is the appropriate electrical test resistance values for;
Commercial?
Mil?

What is the appropriate electrical test short circuit current values for;
Commercial?
Mil?


Why I ask is, we have had a board house send us specs on their
electrical test and they have specified a resistance threshold of
1K.
In other words the trace resistance may be 999 Ohms and it will pass.

My feeling is the trace resistance should be in the mili-ohms,
roughly .050 Ohms.

What does IPC-ET-652 or whatever document that applies state?
