I'll try to be discreet. If there is no functional impact, then a "let
the chips fall where they may" approach is acceptable. If the part
markings are not visible or the vision recognition algorithm of an AOI
machine is impaired, then they may be a problem.

Subject: [TN] Repair Need for Inverted Chip Resistors

TechPros,

Can anyone tell me if there's a reliability concern with allowing chip
resistors to be mounted upside down?  Our current policy requires that
we repair these, and I feel that to be unnecessary.

IPC-A-610D shows this to be an acceptable condition on all classes of
product, and our customer has no specific contractual requirement.

I'd like to try to change this policy at our facility, and welcome any
commentary you might have on the subject.

Thanks in advance for your help,

Leland Woodall
