Impact of Assembly Cycles on Copper Wrap Plating

The PWB industry needs to complete reliability testing in order to define the minimum copper wrap plating thickness requirement for confirming the reliability of PTH structures. Predicting reliability must ensure that the failure mechanism is demonstrated as a wear-out failure mode because a plating wrap failure is unpredictable. The purpose of this study was to ...

A Study on Effects of Copper Wrap Specifications on Printed Circuit Board Reliability

During the manufacturing of printed circuit boards (PCBs) for a Flight Project, it was found that a European manufacturer was building its boards to a European standard that had no requirement for copper wrap on the vias. The amount of copper wrap that was measured on coupons from the panel containing the boards of interest was less than the amount specified in IPC-6012 Rev B, Class 3. To help determine the reliability and usability of the boards, ...

Printed Circuit Board Quality: Copper Wrap

Motivation: High reject rates for PCBs due to specification non-conformances ... Multiple rebuilds causing impactful schedule delays + Copper Wrap + Wicking + Etchback + Annular Ring ... Are rejected boards reliable? ... What are PCB quality requirements for? + Reliability: fewer cycles-to-failure? + Manufacturability: define threshold of modern manufacturing capability?
