Flex Circuit Materials

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.

It s important to be aware of the materials used in flexible and rigid flex circuits. 9 µm to 10 oz. 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.

Although they are small and light weight they are durable and capable of handling high density. 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. Flexible circuits pose unique challenges for metallization.

Tech etch uses this film as the base layer on single metal layer flex circuits and for inner layers of multilayer circuits. Materials used for flex circuit boards. 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. All the materials in multilayer flex laminates must be chosen to combine mechanical flexibility with sufficient electrical performance.

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. They absorb shock and vibration easily in high stress applications. We can use flexible circuits in a variety of applications. The tight bending radii present in many design configurations require flexible metal layers with high electrical conductivity.

All flex is a flexible printed circuits manufacturer that has consistently delivered high quality flex circuits for two decades. 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. Different forms of copper may be used including half hard rolled annealed and electro deposited. Each element of the flex circuit construction must be able to consistently meet the demands placed upon it for the life of the product.

Flat flexible circuits are able to fold into nearly any shape due to their flexibility and smaller size. The conductive layer may also be made of alternate materials such as beryllium. 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. Insulator materials polyimide film is the most common insulator material used for flex circuits.

Typical single layer flex circuit stack up.
