Quality issues are never black and white, however. The problem on two different boards presented could be from one issue, or from separate issues that both have that common symptom. Alternatively, one issue can be presented in many ways, with two boards in a batch showing differently, but sharing that common issue. Due to their complexity, rigid-flex and flex circuits can have a myriad of issues that could show up. And while they can have so many, most issues we encounter boil down to six quality issues. These quality issues can range from issues in the transition zone to stiffener to flex registration, cosmetics of the material and finished product, creases in the flex material, voids between the stiffener and the flex, and delamination at assembly. ### **Insiders Look:** - Issues in the Transition Zone - Creases in Flex Material - Delamination at Assembly - And more… ![Top 6 Quality Issues Seen in Flex & Rigid-Flex Printed Circuit Boards](https://info.epectec.com/hs-fs/hubfs/ebooks/top-6-quality-issues-seen-in-flex-and-rigid-flex-pcbs.jpg?width=400&name=top-6-quality-issues-seen-in-flex-and-rigid-flex-pcbs.jpg "Top 6 Quality Issues Seen in Flex & Rigid-Flex Printed Circuit Boards") #### Learn More About These Issues Fill out our short form to receive your FREE copy!
