FPC/CCS Design Technical Exchange Report: Key Points

This document is a technical exchange report focusing on the design of Flexible Printed Circuits (FPC) and CCS (likely Cell Contacting System) for new energy applications. It begins with an introduction to FPC, defining it as a flexible circuit board made by etching copper foil on polyimide or polyester film, offering high reliability and flexibility. Key features include small size, light weight, and high flexibility, enabling three-dimensional movement and integration. Applications span cameras, laptops, mobile phones, medical equipment, automotive electronics, new energy, aerospace, and military products. The report classifies FPC based on conductor layers, polyimide, adhesive, and coverlay openings, with scenarios for single-sided pads, double-sided pads with sufficient routing space, and rigid-flex designs. It also covers design key points and precautions, specifically focusing on FPC cantilever design, detailing cantilever types and considerations to ensure reliability and performance in demanding environments.
