Copper Thickness Requirements for Flex Circuits

There are many reasons an end user will specify the copper thickness of a printed circuit. The most obvious reason would be for current carrying capacity, but copper thickness also directly impacts thermal performance and impedance. All these are vital properties...

Flexible Circuit Design vs. Traditional PCB

It is common for many designers and engineers to think of a flexible circuit design as a printed circuit board (PCB) that can bend. While it is true that both PCBs perform the same electrical function, the structural and mechanical differences are significant, and not...

Soldering Flexible Circuits

The most common methods for component attachment on flexible circuits and rigid printed circuit boards involve soldering. The basic principles for soldering are the same for both flex and hard board, but soldering components to flexible circuits involves certain...

How to Avoid Trace Fracturing and Cracked PCBs

In most cases, you can trace cracked PCB or trace fracturing back to mechanical stress introduced through design choices, material selection, or packaging constraints that don’t fully account for real operating conditions. When copper in flexible circuits is...

Zero Insertion Force (ZIF) Connectors

Mating with Zero Insertion Force (ZIF) connectors is an increasingly popular termination for flexible printed circuits. Use of a ZIF connector eliminates the need for a mating connector. The flex end “mates” into the connector, usually located on a rigid board....
