Flexible Circuit Board Material

Flexible pcbs with various types of stiffeners.

Flexible circuit board material.

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. You will find flex pcbs inside most cellphones or similar miniaturized gadgets. Aluminum on pen material conductors copper is the most widely used conductor and comes in various thicknesses to meet each customer s requirements. Multilayer rigid flex pcbs also include prereg fiberglass as middle substrate layers.

In a rigid flex design the flexible part of the board resembles a typical flex circuit. Only one flexible conductive layer with two insulating layers on each side. Single layer flexible pcb. Flex circuit boards come in different types.

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. Just like standard pcbs these rigid areas often have fiberglass as a substrate material. Flexible substrate material such as fccl coverlay prepreg and solder mask and reinforcement board have to feature fire resistance and be halogen free. Stiffener material can be used to add addition durability and abrasion resistance.

Double layer flexible pcb. In summary if you have flexible circuit design or flexible printed circuit board needs we can help. Outer layers may have exposed or covered pads. Produce your own single sided flexible printed circuits using a solid ink printer copper coated polyimide film and common circuit board etching chemicals.

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. You can etch flexible circuit boards using a 3d printer. Additionally working components in the machinery or product may rub against the circuit board and cause excessive wear and tear. Diy flexible printed circuits.

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. Two flexible conductive layers separated from each other with an insulating layer. A wide variety of materials and configurations are available to address the needs of today s design applications. Pyralux laminates for flexible and rigid flex pcbs dupont has long been a market leader in laminates for flexible and rigid flex pcbs.

Material selection is determined by the combination of the electrical mechanical bend requirements and cost considerations of a specific design. Meanwhile the rigid sections have similar materials to standard rigid pcbs.
