Introduction
Flexible printed circuits (FPCs) enable integration of electronics in bendable and dynamic applications through their thin, lightweight construction. Choosing a capable flex PCB manufacturer is key to get high quality circuits critical for reliability.
This article profiles the top 20 global flexible PCB manufacturers based on market share, capabilities, quality certifications, and industry reputation. The major evaluation factors are also outlined to help identify the right partner for your flex PCB needs.
Overview of Flexible PCBs
Flexible PCBs contain conductive traces etched on thin, bendable dielectric films like polyimide. This allows flexing, twisting or conforming to fit product enclosures.
Benefits:
- Thin and lightweight – thickness down to 12 microns
- Withstand vibrations, shocks, flexing movements
- Can be bent, folded, twisted dynamically
- Enables smaller, lighter, and more portable electronics
- Complex 3D interconnects and stacking options
- Used in challenging conditions – Temp, dust, moisture, chemicals
Flex PCBs are widely used in consumer electronics, medical devices, industrial equipment, aerospace avionics, and automotive designs. The ability to integrate flex PCBs during product assembly also eliminates interconnection cables simplifying manufacturing.
