Does any one have a general cost percent going from class 2 to class 3 for the same Assembly.. Or, general up charge percent when biding class 2 vs class 3?

We expect aerospace to be IPC-A-610, Class 3 and J-STD-001, Class 3. The above quality statement stecifies: * "IPC 610, Class 2 acceptability." This is unclear. Should this be "IPC-A-610, Class 2 acceptability?" * No class for J-STD-001. Should we a

I can't say I've ever heard that you shouldn't rework class 3 products. Since class 3 and class 2 are inherently inspection standards, rework might be required to meet class 3 specs. In the past, that has been an issue, as everyone wants to produce

I have asked that same question to a co-chair of the J-STD-001 committee who in turn checked with personnel at IPC. The answer I received is that yes you can apply the Class 3 assembly requirements using a class 2 PWB but the resultant assembly will
