FPC Double-Sided Flexible Circuits , FPC Double Side

FPC Double Side

The circuits have two conductive layers that are usually accessible from both sides. The main features include component assembly on both sides. Although, their capacity to flex reduces because of their thickness and complexity in design but their ability to interconnect between sides using plate-through hole helps to implement complex designs without compromising on flexibility.

Flexible circuit board (FPC) is mostly used in the applications and markets from medical equipment, telecommunications, compter peripherals, instrumentation and industrial. Our designing team provides layout design, life-cycle and environmental testing to our customer. At each stage, our quality team provides process improvement. We are the only choice for quick prototype, competitive price, and quick production.
