Custom 0.5oz-3oz Copper Flex PCB Fabrication 1-8 Layers

The FPC three-layer board is made by pressing one inner layer and two outer layers, with surface treatment using a high weldability gold deposition process (environmentally friendly). The insulation material is made of polyimide with excellent flame resistance. This product has wide applications in high-precision and demanding electronic products.

Single-sided flexible circuits feature a single conductor layer on flexible dielectric film, with component termination accessible from one side. Commonly used with protective coatings, these circuits enable innovative applications like transparent LED films for automotive lighting and LED glass.

Double-sided flex circuits with two conductor layers typically include plated through holes, allowing component placement on both sides. This design simplifies crossover connections and is commonly used in applications like laptop mousepad-to-motherboard connections.

Multilayer flex circuits (three or more conductor layers) offer complex interconnection capabilities. Discontinuous lamination techniques can be employed in areas requiring maximum flexibility while maintaining structural integrity in other sections.

Rigid-flex circuits combine rigid and flexible substrates in a single structure, offering both stability and flexibility. Originally popular in military applications, they're now common in consumer electronics like laptops, particularly for hinged display cables requiring thousands of flexures.
