92 DESIGN007 MAGAZINE I JULY 2021 Flex007 Feature by Andy Shaughnessy I-CONNECT007 Rigid-flex circuits have become almost ubiq- uitous over the past decade; most personal electronic devices contain at least one rigid-flex circuit. But there's a downside to rigid-flex: Re- spins are almost a given with rigid-flex designs. And rigid-flex re-spins can be quite expensive, since this technology costs quite a bit more, on average, than flex or rigid boards. In this free 22-minute on-demand webinar, Flex & Rigid-flex DFM Analysis, Kevin Webb, an NPI technical marketing engineer with Siemens EDA, explains how using Valor NPI early in your rigid-flex design flow can help you reduce your rigid-flex re-spins, or possibly even eliminate them completely. Webb discusses how Siemens' drive to "le- shi" manufacturing information into the designer's hands allows rigid-flex designers to make more informed decisions early in the design cycle, where mistakes are less costly. Webb walks the user through a typical rigid- flex design, explaining how Valor NPI is opti- mized to work with rigid-flex circuits. e Rigid-Flex Design Without Re-Spins—A Webinar Review
