Beryllium Copper: Flex Circuit Manufacture - the classification and the essential

Thursday, December 10, 2009 at 3:07 PM

Flex circuits, flexible electronics and flexible circuits have been from the Institute of Printed Circuits as "agreement modeling of PCBs defined by a flexible base material with or without flexible cover layers". This is the technology that meets electronic circuits through the creation of components for high performance electronic materials for flexible basis.

Flex Circuit
Manufacture - The Essentials

The ability to successfully manufacture complex integrated flexible interconnect is caused by a beryllium copper number of elements. Here are some key elements in the manufacture of flexible circuits.

The ratings of the

Flex circuits are classified into three

beryllium copper

categories according to frequency of flexion divided in his life:

• Bend and will stay - a flexible circuit that is intended to collect, at beryllium copper, any flexion.

• Flexible - A circuit that is destined to be flexed hundreds of times in your life.

• Dynamic Flex - Flexible Circuits Flexible thousand beryllium copper times in your life.

All types of flex circuits have connotations of a different design. A flexible circuit can sided, double-sided, dual access, rigid or flexible multi-layer multilayer.

The materials used

A process for producing flexible circuits using plastic substrates such as polyimide (PI), polyethylene naphthalene (PEN) and polyester (PET). Other materials are gold, constantan, beryllium, beryllium copper and stainless steel and various metal sheets.

The wiring can with conductive silver ink or etched copper printed rolled beryllium copper annealed (RA) or high aspect ratio are copper (ED).

Flex - the applications are in abundance

Improved reliability

Although flexible electronic assemblies are beryllium copper common components beryllium copper in circuits that beryllium copper contain PCBs, but the substrates are developed using a much more flexible in nature. Eliminate wiring errors and Hubs for the use of tracks and beryllium copper, rigid multi-layer flexible circuits are much needed reliability citcuits flex

Portability

In the flexible circuit board may, in three dimensions, which can be easily beryllium copper installed in the room, suffocating be folded devices.

The union of moving parts

Join The coherent way to the moving parts will use the flexible circuit and dynamic. It makes sense to link UPS million.

Weight

Because of its Lightness and thinness compared to standard joints, advanced electronic devices using flexible circuits are lighter than 75%.
