Today, flexible circuits are used in nearly every imaginable type of electronic product. They represent the fastest growing interconnection market segment due to the many advantages of using flexible circuits in a myriad of electronic applications.

Cookbook

Single-Sided Flex Circuits

Single-sided flexible circuits consist of a single conductor layer on a flexible dielectric film with termination features accessible on from one side. Such circuits can be fabricated with or without protective coatings as cover layers or cover coats.

Applications:
Polyimide-Kapton with Acrylic adhesive / Two-way antenna pager / Printer cables
/ Automotive or general interconnects used in electronic devices.


 

Cookbook

Double-Sided Flex Circuits…

Double-sided flex circuits are constructed with two conductor layers, with or without plated through holes. Terminations for such circuits can easily be provided on either side of the circuit. As with single-sided flex, double-sided flex circuits can be fabricated with cover layers.

Applications:
Medical / Environmental / Test and Measurements / Automotive and other general electronic devices.


 

Cookbook

Rigid-Flex Circuits…

Rigid-flex circuits are of a hybrid construction consisting of rigid and flexible substrates laminated together into a single package and electrically interconnected by means of plated through holes. Such flexible circuit types have enjoyed tremendous popularity among military product designers, but have in recent years made gains in the commercial world. Rigid-flex boards are normally multilayer designs, however double-sided (tow metal layer) constructions are possible, and have been used in certain microelectronic applications.

Applications:
Aerospace, all types of electronics used in Military Devices, Consumer Electronics where feature and space is critical, such as laptop computers.


 

Cookbook

Sculptured Flex Circuits…

Sculptured flex circuits utilize a special patented construction yielding a flexible circuit wherein the copper conductor has different levels of thickness at different areas. This is accomplished by selectively etching the copper foil to different depths in different areas. Typically, bare metal contacts protrude from the edge to allow plug-in connections.

Applications:
General interconnects which replace crimping technology. Sculptured flex provides more reliable connection after assembly.


 

Cookbook

Multilayer Flex Circuits…

Flex circuits having three or more layers of conductors which are interconnected by way of plated through holes are referred to as multilayer flex. Layers may be continually laminated together throughout construction in such cases where maximum flexibility is required, and where flexing or bending occurs can be manufactured unbound.”

Applications:
High density SMT electronic applications / Automotive / Test and Measurement / Medical Aerospace.


 

Cookbook

Double Access or Back Bared Flex Circuits…

Double access flex, also known as back bared flex, are circuits with a single conductor layer which is processed in a manner that allows access to the conductors form both sides.

Applications:
Medical / Environmental / Test and Measurements / Automotive and other general electronic devices
