Fellow Technets, A question was posed to me by a customer claiming that IPC-R-7221 stated that a maximum of 1 rework per board for class 3 was acceptable. Specifically they stated that this means only 1 solder joint per board could be touched up. I have been searching high and low for IPC-R-7221 but to no avail have yet to find the existence this publication. My questions are: 1. Does IPC-R-7221 exist? 2. If so, can anyone support or refute the claims of only being able to touch up 1 solder joint on a class 3 assembly? Any help or input would be appreciated.
