Flexible Circuit Board Material

Material selection is determined by the combination of the electrical mechanical bend requirements and cost considerations of a specific design.

Flexible circuit board material.

Produce your own single sided flexible printed circuits using a solid ink printer copper coated polyimide film and common circuit board etching chemicals. Make flexible circuit boards using a 3d printer. Two flexible conductive layers separated from each other with an insulating layer. Flexible substrate material such as fccl coverlay prepreg and solder mask and reinforcement board have to feature fire resistance and be halogen free.

Selecting the optimum flex circuit board material is a key element to the success of a flexible circuit design. Meanwhile the rigid sections have similar materials to standard rigid pcbs. You will find flex pcbs inside most cellphones or similar miniaturized gadgets. 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.

Double layer flexible pcb. Additionally working components in the machinery or product may rub against the circuit board and cause excessive wear and tear. Multilayer rigid flex pcbs also include prereg fiberglass as middle substrate layers. Stiffener material can be used to add addition durability and abrasion resistance.

They can be made of very thin copper clad board material or even conductive fabric standard copper clad circuit board material fr4 of any thickness can also be etched using this method. Single layer flexible pcb. Only one flexible conductive layer with two insulating layers on each side. You can etch flexible circuit boards using a 3d printer.

Flex circuit boards come in different types. Outer layers may have exposed or covered pads. A wide variety of materials and configurations are available to address the needs of today s design applications. New type copper foil leading conducting material of flexible pcb is copper or copper foil and sometimes alloy is also used including aluminum nickel gold and silver etc.

In summary if you have flexible circuit design or flexible printed circuit board needs we can help. Our extensive family of pyralux interra and temprion branded products expands possibilities for flexible laminates embedded passives and thermal performance in demanding applications such as 5g networks. Aluminum on pen material conductors copper is the most widely used conductor and comes in various thicknesses to meet each customer s requirements. Pyralux laminates for flexible and rigid flex pcbs dupont has long been a market leader in laminates for flexible and rigid flex pcbs.

Flexible pcbs with various types of stiffeners. In a rigid flex design the flexible part of the board resembles a typical flex circuit.
