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...

Vias and Through-Holes in a Flexible Circuit

I heard one of our Applications Engineers describe our product as “making sandwiches”. It is a pretty good metaphor as it helps visualize a cross section of a printed circuit with several layers of dissimilar materials. Most flexible circuits and PCB’s have multiple...

Cost and Price of a Flexible Circuit

In the right application, flexible circuits can reduce wires, eliminate connectors and rigid circuits. They might also simplify component assembly and reduce wiring errors. But competitive products such as rigid circuits, wires and connectors also have their place in...

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 on Flexible Circuits

Flexible circuits are ideal for applications that require bending and twisting. This flexibility gives designers options that are not available with the typical printed circuit board. This does not mean that a flexible copper trace will never crack, as like most...
