Best Practices for Designing Rigid-Flex Boards
The folks over at TechnoTronix recently published the blog post, “Top things you need to know about the Rigid-Flex PCB Manufacturing Process!”
They do a great job of listing the most popular industrial applications and the advantages of rigid-flex PCBs. As TechnoTronix tells us, these types of boards are reliable and cost effective, which is why they are so widely used in the industry.
But there are best practices to follow when designing rigid-flex boards. The blog post gives a good top-level look at the design guidelines and details the manufacturing processes. If you’re looking for more in-depth instruction, IPC offers a six-week course, PCB Design for Rigid-Flex Boards starting on March 15, 2022.
This course covers basic and advanced flexible circuit design, materials, manufacturing processes and documentation, including IPC standards. Assignments include designing single and multi-layer boards, define stackups for signal integrity, assembly array and creating a documentation package, plus a final exam.
Our instructor, Kris Moyer, also suggests some supplemental materials that are resources every designer needs.
