Top 5 Reasons for Using Stiffeners on Flexible PCBs

Written by Zachary Walker
Posted on December 5, 2023 at 9:12 AM

A stiffener is defined as a piece of material adhered to a flexible printed circuit board that rigidizes one zone of the board. While a stiffener holds no electrical value to a PCB, it does maintain a crucial part of most flexible PCBs in the market by hardening that portion of the board.

Pros and Cons of Using Flexible PCBs In Your Application

Written by Zachary Walker
Posted on October 19, 2023 at 8:57 AM

Applications that rely on printed circuit boards (PCBs) to control functions can experience difficulties when having operating components or when designed in slimmed or smaller sizes. Standard rigid circuit boards have to be made in specific sizes and dimensions, which can make it difficult when designing working components that could scrape against and damage the PCB.
