Catalytic anodes for electrodeposition: a study for acid copper printed circuit board (PCB) production

D.R. Gabe, A.J. Cobley

Insoluble anodes have long been used as an alternative to the preferred soluble types, primarily for their practicality and without great attention to their efficacy. However…

A variant of conductive filament formation failures in PWBs with 3 and 4 mil spacings

Keith L. Rogers, Michael G. Pecht

To show how the use of conductor spacings below 4 mil in printed wiring boards (PWBs) can introduce an unanticipated failure mechanism, leading to current leakage and short…

Conductive anodic filament (CAF) formation: an historic perspective

Laura J. Turbini

Conductive anodic filament (CAF) is a failure mode in printed wiring boards (PWBS), which occurs under high humility and high voltage gradient conditions. This paper aims to…

Tin whisker risk assessment

Tong Fang, Michael Osterman, Sony Mathew, Michael Pecht

To present a methodology, including the algorithms, to quantify the risk of failure from tin whiskers and to present a dynamic risk trend based on the distribution of each of the…

Experiences with peel strength

Rudolf Wiechmann

Peel strength numbers are part of a laminate's specifications and should characterize the specific bond performance (copper adhesion) under test conditions. Unfortunately, from…
