HDI R-F Multi-Layer PCB with HASL Finishing

The HDI R-F Multi-Layer PCB with HASL Finishing supplied by Xing Da Circuits Technology Co., Ltd. is a high-density interconnect board that incorporates a rigid-flex structure for demanding electronic applications. While the exact layer count is not disclosed, the board is described as multi-layer and supports high-frequency signals. The surface is finished with Hot Air Solder Leveling (HASL), delivering good solderability and corrosion resistance. Production is based in China, and the supplier markets the product for use in telecommunications, automotive and consumer electronics.

The board typically uses an FR-4 substrate, a standard material offering stable dielectric properties for high-speed designs. Typical copper weight of 1 oz/ft² and a standard board thickness of 1.6 mm are common for such PCBs, providing a balance between mechanical strength and signal integrity. Minimum trace width of 5 mil is achievable, and impedance control to 50 Ω is often provided as a standard option. The HASL finish aligns with industry practices for cost-effective solderability.

Potential buyers include OEMs developing smartphones, tablets, industrial automation controllers and automotive infotainment systems that demand compact, high-performance circuitry. Xing Da positions itself as a supplier capable of flexible MOQ and both prototype and volume production, though exact quantities are not listed. Importers should confirm trade terms, packaging format such as anti-static bags, and any required certifications before finalising the purchase.

Xing Da Circuits Technology Co., Ltd. is located at 49th Building New Zone, Dongfeng Village, Songguang Town, Baoan District, Shenzhen, Guangdong, China, 518105. The supplier holds a harbour trust tier but currently shows a response rate of 0 % with no average response time recorded, indicating that response metrics are not publicly displayed.

The company states that it offers HDI rigid-flex PCBs with HASL finishing and can serve industries such as telecom, automotive and consumer electronics. No specific certifications, MOQ or lead-time information is provided in the listing, so buyers should request these details directly. Xing Da emphasizes flexibility in order volumes and the ability to handle both prototype and mass-production runs.
