Import Hdi Pcb — Buy in Bulk from Supplier in China

The Hdi pcb offered by Sun Light Pcb & Technologies Ltd. is built on an FR‑4 substrate and features a 3 + 4 + 3 layer stackup designed for high‑density interconnects. The finished board thickness is 1.0 ± 0.1 mm, with a minimum trace width and spacing of 0.10 mm each, and laser‑drilled vias as small as 0.1 mm. Surface finishing is ENIG, and the board supports blind and buried via technologies for complex routing.

In the broader market, HDI PCBs of this type commonly use a 35 µm (1 oz) copper weight and are manufactured to meet a 50 Ω ± 10 % impedance control, which is standard for communication equipment. Typical tolerances for overall thickness are ±0.1 mm, and visual inspection follows IPC‑A‑600 Class 3 criteria. ENIG finishes are preferred for their flatness and solderability, especially in high‑frequency applications.

These boards are suited to communication devices, networking gear, and advanced consumer electronics where signal integrity is critical. Importers should confirm the minimum order quantity, preferred Incoterm (FOB or CIF from Shenzhen) and any required packaging specifications before placing an order. Lead time and payment terms are not disclosed in the listing, so buyers need to verify these details directly with the supplier.

Sun Light Pcb & Technologies Ltd. is located at Xin, Nuo, Building, Fenghuang Western Area, Bao An Province, Shenzhen 518103 Guangdong, China. The supplier is classified as an imported tier with a harbor trust tier, and the platform records a response rate of 0.00 and no average response time, indicating that enquiries should be initiated proactively.

The company focuses on printed circuit board manufacturing, offering services from prototype to volume production, including multilayer HDI boards such as the one described. No additional certifications, capacity figures or client references are listed, so importers are advised to request capability statements and sample boards before committing to larger volumes.
