It seems to me that this is one of the first recorded cases in history of Quality telling Manufacturing NOT to rework an assembly!

(grinning) Boy I bet that sent some heads spinning...it was of course said off the cuff...so relax... My question would be what affect will there be on the exposed copper over time? Will, or could this lead to reliability issues later? If that amount of exposed copper is allowed, and it reliability including normal function is not affected then leave it alone...to mess with it may only cause more expense...if reliability could be affected...then perhaps it needs to be addressed...it's all about weighing the factors involved... Now, for those production types whose head exploded on that first paragraph...duct tape wrapped tight around the skull will contain the gray matter...just a thought...

There is some copper exposed by the body, but the lead in the solder connection is good. Per IPC-610, if copper is exposed due to deformation or nicks/gouges >10%, it is a defect. We have absolutely no deformation in these component leads. My decision was to leave them in the board. We have a Mfg. Engineer who wants to have them all replaced. He feels I have interpreted the IPC-610 incorrectly. I feel that this is unnecessary rework that could damage the PCB. Any supporters out there? Connie M.
