Import 4-Layer Pcb With Osp Surface Finishing — Buy in Bulk from Supplier in China

This is a 4-layer printed circuit board with OSP (Organic Solderability Preservative) surface finishing, produced by Xing Da Circuits Technology Co., Ltd. in Shenzhen, China. The board offers a finished thickness range of 0.5 to 6.0 mm, with a maximum panel size of 450 mm x 500 mm for multilayer configurations. It uses FR-4 as the base material, with options for CEM-1, CEM-3, high TG FR-4, and halogen-free variants.

The PCB supports advanced features such as buried and blind vias, controlled impedance, and BGA compatibility. Copper thickness in holes exceeds 20 µm, and the board achieves a shape tolerance of ±0.13 mm with hole tolerances of ±0.076 mm for plated-through holes and ±0.05 mm for non-plated holes. Solder mask colors include green, yellow, black, white, red, and blue, with profiling options like punching, routing, V-CUT, and beveling.

Typical applications include consumer electronics, industrial controls, and telecommunications, where short lead times and RoHS compliance are critical. The supplier offers standard vacuum or plastic bag inner packaging with outer carton protection. Buyers should confirm specific requirements for high-frequency or HDI applications, as these may involve additional testing or material grades.

Xing Da Circuits Technology Co., Ltd. operates from Shenzhen, Guangdong Province, China, with its facility located in Dongfeng Village, Songguang Town, Baoan District. The company is positioned as an imported-tier supplier, indicating a focus on serving international buyers. While its response rate is currently listed as 0.00, the profile confirms it holds certifications such as ISO9001:2000, ISO14001, UL, SGS, and RoHS compliance, which are critical for PCB buyers requiring adherence to quality and environmental standards.

The supplier’s production capabilities cover a broad range of PCB types, including rigid, flex, flex-rigid, and HDI boards, with surface finishes extending beyond OSP to HASL, chemical gold, immersion silver, and gold plating. Payment terms include T/T, L/C, and Western Union, with FOB Shenzhen and Hong Kong as standard shipping points. The absence of a stated MOQ or lead time in the profile suggests these are negotiable and should be confirmed directly with the supplier.
