All -

I need the forum's help on a quality issue that we are experiencing with one
of our customers.

Specifically, we have a customer that is rejecting board assemblies due to
chip-outs (nicks) in the adhesive coating on various resistors. We are
questioning whether or not these chip-outs in the coating are actually
defects.

IPC-A-610 Rev. D (section 9.2) does state workmanship parameters for
adhesive coating, but it only applies to 1206 and larger devices. The
devices in question are 0402's.

Our question: Is there an industry standard quality/workmanship
specification for adhesive coating on devices with a case size smaller than
1206?
I will provide Mr. Steve Gregory some pictures to add to his website, when
he has time.

Kind Regards,
Dacia
