Flexible Printed Circuits - Copper Conductors (FPC)

Flexible Printed Circuits - Copper Conductors (FPC)

Parlex reliably packages circuitry in limited space with Rigid-Flex or solves a crosstalk shielding issue with Multilayer Flex Circuitry. Our flexible printed circuit capabilities includes a wide range of design choices including line spacing, materials, surface finishes and panel sizes. Parlex is experienced in servicing multiple industries including Automotive, Industrial, Home Technologies, Medical and Life Sciences. Parlex engineers collaborate with customers to address the most demanding flexible circuit designs and we have the manufacturing expertise to support the project from prototyping to mass production.
