Import 4 Layer Rigid-Flex Pcb — Buy in Bulk from Supplier in China

This is a 4 layer rigid-flex printed circuit board with 2 flex layers, combining rigid and flexible substrates in a single unit. The surface finish is immersion gold, a standard for reliability in high-performance applications. Minimum hole size is 0.35mm, while the minimum line width and space are 8 mils and 5.9 mils respectively, allowing for dense component placement. The rigid section measures 2.00mm in thickness, and the flex section is 0.24mm, with an overall board size of 397.89 x 555mm.

The rigid-flex design is built using FR-4 epoxy glass for the rigid layers and polyimide for the flex layers, a typical material pairing for this type of PCB. This construction supports dynamic flexing while maintaining structural integrity, ideal for applications where space and weight are critical. Industry-standard tolerances for such boards include ±0.1mm for hole position and ±0.05mm for layer-to-layer alignment, though exact values depend on the supplier’s manufacturing capabilities.

These boards are used in aerospace, medical devices, and consumer electronics where reliability and space efficiency are paramount. Buyers typically source them in panel sizes for assembly, with packaging designed to prevent static damage. Lead times and MOQs vary by supplier, but bulk orders often ship via sea freight under FOB or CIF terms. Confirm the supplier’s testing protocols, such as flying probe or fixture testing, to ensure quality.

Head Electronic Co., Ltd. operates from Dongguan, Guangdong Province, China, with its registered address at Room 1517, Caijing Business Building, Nancheng District. The company holds a harbor trust tier, indicating a basic level of verified information, though its response rate and average response time are currently not available.

As a PCB supplier, the company specializes in rigid-flex boards, with this listing confirming capabilities for 4-layer configurations with immersion gold surface treatment. No additional details about certifications, production capacity, or client base are provided in the available profile, so buyers should request these directly for further verification.
