Rigid-flex PCB FAQ
1.What types of rigid-flex PCBs are there?

Rigid-flex printed circuit boards are mainly divided into three types, including single-sided rigid-flex PCB, double-sided rigid-flex PCB, and multi-layer rigid-flex PCB.

2.What are the steps in the rigid-flex PCB manufacturing process?
The rigid-flex PCB manufacturing process involves multiple steps including substrate preparation, circuit pattern generation, overlays, cutting flex, electrical testing, and verification.
3.What is rigid-flex PCB?

A rigid-flex PCB is a hybrid board that integrates components from a rigid board and a flex circuit. It offers several advantages, including improved reliability and reduced weight.
