Some Class 3 customers don't want their products to be comingled in assembly processes with Class 2 products.

Are you capable of doing Class 3 products? Does the design, bare PCB board and assembly meet the requirements of Class 3?

We have some new customers that are requiring class 3 IPC standards, and my question is, how would that translate into a labor rate increase as compared to class 2 rates? I'm assuming the labor quote would increase by at least 15-20%, if not more. An

Can I apply IPC-610 class 3 workmanship standards to an assembly made with a IPC-600 class 2 PCB?

Hi Scott,Thank you for the response. I was also thinking the same that the assembly will no longer be Class III. Thanks again.

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

Check out IPC-A-600. Revision G (July 2004) section 3.2.3 (surface) and section 3.2.4 (internal) give min/max thicknesses for various weight copper. The min also changes depending on what class (1-3) standard you are working to.

The closer your inspection the more defects you will find, the more rework you do the possible cost you will add and the potential increase of damage you could do to your products if rework is not up to a machine copyable standard. "Is there any in

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

How about rework (touch-up) for Class 3? Some say that you are not allowed to rework anything for Class 3. Though I have not found any proof for this 'requirement' in the standards.
