Flexible printed circuit boards (FPC) are made with flexible insulating substrates, offering advantages that rigid PCBs cannot match. They can bend, wind, fold, and be arranged in any spatial configuration, enabling three-dimensional movement and stretching for integrated component assembly and wire connections.

• Reduces electronic product volume significantly
• Ideal for high-density, compact, and highly reliable applications
• Widely used in aerospace, military, mobile communications, laptops, and digital cameras
• Can replace multiple rigid boards and connectors
• Single-sided circuits are perfect for dynamic or high-flex applications

• Superior Flexibility: Withstands repeated bending without cracking
• Thermal Stability: Operates up to 260°C, suitable for soldering
• Electrical Properties: Low dielectric constant maintains signal integrity
• Chemical Resistance: Resists moisture, UV, and harsh environments
• Dimensional Stability: Low thermal expansion minimizes distortion

Flex PCB manufacturing involves specialized photolithographic technology with precise control at each stage:

• Design preparation with specific flex PCB considerations
• Photolithography and etching with dimensional accuracy challenges
• Plating and surface finishing processes
• Multilayer construction with precise alignment
• Precision cutting and shaping techniques
• Component assembly and electrical testing
