Dielectric Covering Options for Flexible Printed Circuits

The circuit traces of a flexible PCB often needs a dielectric covering to selectively protect the traces from shorting against a conductive surface or to prevent select areas from subsequent metal coating or plating operations. The dielectric will have openings that...

Creating the Cutline of a Flexible Circuit

One of the great features of a flexible PCB is that it can come in just about any shape or size. The final shape is defined when the completed circuit pattern is removed from the base substrate. Flex circuits are either fabricated in sheets or in rolls. There are a...

Conductor & Filleting Guidelines

This section of our guide addresses rules specifically pertaining to conductor and pad design recommendations. Due to the flexible nature of the material during both manufacturing and application use, the following information is recommended to produce the highest...

Imaging Process for Flexible Circuits

One of the first steps in fabricating a flexible circuit is to create a circuitry pattern. In order to correctly define the circuit pattern, one needs to understand the basic process for building a circuit. Processes tend to fall in one of the following two...
