Import 4l Flex-Rigid Board — Buy in Bulk from Supplier in China

The 4L Flex-Rigid Board from Shenzhen Hemeixin Electronic Co., Ltd. integrates rigid FR-4 layers with flexible polyimide substrates, bound by a standing PP prepreg with a Tg of 170°C. The copper layering is configured at 1/0.5/0.5/1 OZ, corresponding to 35 µm, 17.5 µm, 17.5 µm, and 35 µm across the four layers. With an overall thickness of 1.00 mm ± tolerance, it supports dense interconnects in compact form factors where mechanical stability and dynamic flexing are both required.

The board uses a standard FR-4 epoxy glass composite for the rigid sections and polyimide film for the flexible parts, with a coverlay finish for environmental protection. Typical applications demand IPC-6013 Class 2 or 3 standards for reliability, with controlled impedance traces and fine-pitch components. The flex sections are usually rated for 10,000 to 20,000 bend cycles, a standard benchmark for consumer and automotive electronics.

This configuration is widely adopted in telecommunications, automotive electronics, and wearable devices where space constraints and vibration resistance are critical. Buyers typically source these boards for prototypes and mid-volume production runs, with packaging options including vacuum-sealed trays or anti-static bags. Lead times and MOQs are negotiable directly with the supplier, as are Incoterms such as FOB Shenzhen or CIF to major ports.

Shenzhen Hemeixin Electronic Co., Ltd. is based in Shajing Street, Shenzhen, Guangdong Province, with its registered address at South of 5th Floor, 7 Building, Wanxia Industrial Park, Tongfuyu Industrial Area. The company operates as an imported-tier supplier on the platform, indicating it is established for cross-border trade. Its trust tier is classified as harbor, reflecting a baseline level of verification for international buyers.

The supplier’s profile does not list a response rate or average response time, so direct contact is required to confirm technical details, lead times, or trade terms. The listing provides no additional information about production capacity, certifications beyond ISO and SGS mentions in the source text, or specific client references. Buyers should treat the supplier as a potential partner pending direct verification of its capabilities and documentation.
