Advanced Flex PCB Manufacturing Capabilities

Layer Configurations

RAYMING excels in producing a wide range of flexible PCB configurations to meet diverse application requirements:

• Single-Layer Flex PCBs: Our single-sided flex PCBs feature a flexible dielectric base with conductive copper traces on one side, offering maximum flexibility and cost-effectiveness for simpler applications. These lightweight circuits provide excellent bendability while maintaining reliable electrical performance.
• Double-Layer Flex PCBs: Our double-sided flex PCBs feature two conductive layers with polyimide insulation between them, typically connected by plated through-holes. This configuration supports higher circuit density while retaining excellent flexibility.
• Multi-Layer Flex PCBs: Our 4-layer flex PCBs provide increased routing density and integration, making them ideal for applications in wearable devices, flexible displays, medical equipment, and automotive systems.
• Advanced Configurations: RAYMING manufactures 6-layer flexible PCBs that deliver optimal signal routing and power distribution while maintaining flexibility, perfect for applications requiring complex circuitry in a compact form. We also produce sophisticated 8-layer flexible PCBs, representing the pinnacle of flexible circuit technology with unparalleled complexity and performance in a pliable package.
• Rigid-Flex PCBs: RAYMING is a UL-certified rigid-flex PCB manufacturer offering up to 32-layer rigid and 12-layer flex capabilities, creating hybrid circuit boards that integrate rigid and flexible substrates into a single unit. These designs combine the stability of rigid boards with the flexibility of flex circuits, ideal for complex electronic applications requiring 3D design approaches.
