Flex Circuit Materials

The conductor layer is usually made of copper of thickness varying from oz.

Flex circuit materials.

Tech etch uses this film as the base layer on single metal layer flex circuits and for inner layers of multilayer circuits. Flat flexible circuits are able to fold into nearly any shape due to their flexibility and smaller size. We have responded to market demands and now offer heated circuits and deliver in high volume as well as prototypes from our two minnesota production facilities. Flexible circuits pose unique challenges for metallization.

Different forms of copper may be used including half hard rolled annealed and electro deposited. They absorb shock and vibration easily in high stress applications. Although they are small and light weight they are durable and capable of handling high density. Typical single layer flex circuit stack up.

If you are looking for more information about flex circuit construction methods we recommend seeing our technical article on the latest material and construction methods provide the highest. We can use flexible circuits in a variety of applications. All flex is a flexible printed circuits manufacturer that has consistently delivered high quality flex circuits for two decades. Enabling 5g networks and evs the laminate market is evolving to support the needs of high speed high frequency circuits that connect 5g networks and power the next generation of consumer electronics.

In addition the material must work reliably in concert with the other elements of the flexible circuit construction to assure ease of manufacture and reliability. The conductive layer may also be made of alternate materials such as beryllium. Common flex circuit material stack up below you will find some examples of common material stack ups for flex and rigid flex circuit board construction. Materials used for flex circuit boards.

The tight bending radii present in many design configurations require flexible metal layers with high electrical conductivity. Copper can be an ideal material when deposited in a manner that is compatible with the flexible circuit manufacturing process which is often done on roll to. Even though you may generally allow the fabricator freedom to select the materials based on your application ignorance will not protect you from field failures of the final product. 9 µm to 10 oz.

Materials in flat flexible circuits include bare copper tin plated copper acrylic pressure sensitive adhesives polyester photoinduced electron transfer polyethylene naphthalate tin. Flex circuit materials and construction. Fr 4 and prepreg combine to make up the insulating layers in the rigid portion of a rigid flex circuit. All the materials in multilayer flex laminates must be chosen to combine mechanical flexibility with sufficient electrical performance.

Each element of the flex circuit construction must be able to consistently meet the demands placed upon it for the life of the product.
