It's IPC-7721, not 7221.

|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.
|
|Best regards,
|
|Mike
