It seems like as soon as I master some brand new technology, it’s time for the next big thing and I have to start all over again. Well my PCB designer friends, it’s time for you to learn the next big thing in PCB design, flex and rigid flex. In the fast growing world of PCBs, flexible PCBs are growing the fastest. The Internet of Things (IoT), wearable electronics, and flexible displays are all pushing the industry towards flexible and rigid-flex PCBs. That means it’s time for you to roll your eyes, let out a sigh, and start to learn the design principles for the next generation of PCBs.
