I guess the question is why you are applying OSP?  OSP is normaly applied
over bare copper.  If the flex is copper and just these pads are gold then
I still don't see a problem with coating the gold pads as well.

Does any one have any experience they care to share with OSP over
electroplated gold bond pads (on FLEX)?
It would save us 5 cents each if the gold pads didn't have to be masked
before the OSP is applied...
Thank you for your help!
Sincerely,
