FPC/PCB Pads

1. Introduction to FPC/PCB Pads

Shanyo’s FPC/PCB Pads series contains several answers of the flexible circuit board and metal dome, among them there is single-sided flexible circuit boards, double-sided copper exposed FPC, rigid-flex PCBs (Rigid-Flex PCBs) others are multi-layer flexible circuit boards and flexible PCB metal domes with integrated metal domes.

The FPC/PCB pads use high­-precision etching and punching processes as well as top­ quality PI (polyimide) substrates, and a green surface treatment. They are light in weight, resistant to flex, highly conductive with good reliable touch feedback hence suitable to manufacture input components and connectors for numerous high-end electronic devices.

2. Features of FPC/PCB Pads

High-precision conductivity

Using high-quality copper foil and stable circuit processing, these FPC/PCB pads ensure low impedance and high reliability in signal and current transmission. Ultra-thin flexible structure: Thickness can be as low as 0.05mm, suitable for high-density, compact electronic product designs.

Highly durable metal dome contacts

FPC pads with integrated metal domes provide clear tactile feedback and long-lasting click performance.

Various layer counts and structures

Available in single-sided, double-sided, multi-layer, and rigid-flex structures to meet complex design requirements.

Environmentally friendly materials

Compliant with RoHS, REACH, and other environmental standards, suitable for SMT and reflow soldering processes.

Customized design services

Size, shape, circuit layout, and connection methods can be customized based on customer drawings and functional requirements.
