This product is a custom flexible printed circuit board (FPC) widely used in the consumer electronics industry, including smartphones, smartwatches, wearable devices, and compact smart products.

Manufactured with a green cover film (coverlay) as the main protective layer, this FPC supports high-density circuit routing with a minimum line width and spacing of 0.1mm / 0.1mm, while maintaining an ultra-thin substrate thickness of only 0.05mm.

Designed for applications with limited internal space, the board delivers stable electrical performance while enabling flexible installation and interconnection between functional modules.

Key Specifications

Product Features & Advantages

Ultra-Thin Structure for Compact Designs

With a substrate thickness as low as 0.05mm, this flexible PCB supports lightweight and ultra-slim electronic product designs where space optimization is critical.
