Import Copper Core Pcb With 3 Oz Copper Thickness — Buy in Bulk from Supplier in China

King Sun Pcb Technology Co., Ltd. manufactures a single‑layer printed circuit board featuring a 3 oz copper core and a total board thickness of 3.0 mm, produced in China. The substrate is standard FR‑4, a widely used glass‑reinforced epoxy laminate for electronic assemblies. Copper weight of 3 oz corresponds to approximately 102 µm, providing high current‑carrying capacity and reduced voltage drop. The board complies with typical industry requirements for prototype and low‑volume production.

The surface is finished with an organic solderability preservative (OSP), which protects the copper during handling and is common for lead‑free processes. A white solder mask covers the circuitry, and the board offers a thermal conductivity of 3 W/mK, facilitating heat dissipation in power‑dense designs. Minimum trace width and spacing are 2.7 mil, while the smallest drilled via is 0.15 mm, allowing fine routing. These parameters align with standard design rules for high‑performance single‑layer PCBs.

Potential buyers include electronics manufacturers, R&D labs and small‑batch assemblers that require heavy‑copper boards for power distribution or heat‑spreading applications. The supplier lists a quick‑turn capability, with a 1‑day turnaround for two‑layer prototypes, though exact lead times for single‑layer orders should be confirmed. Packaging is typically in anti‑static bags stacked on pallets, and shipping can be arranged under FOB Shenzhen or CIF Shanghai terms. Prospects are encouraged to request a material safety data sheet and a test report confirming copper thickness before placing an order.

King Sun Pcb Technology Co., Ltd. is situated in Zone B3, Huayuan Science Park, Baoyuan Road, Xixiang Street, Baoan District, Shenzhen, Guangdong, China, postal code 518102. The company is listed with a harbor trust tier, indicating participation in verified supplier networks. Its public profile records a response rate of 0.00, meaning response statistics are not available. The firm specialises in PCB fabrication, offering prototype and small‑batch production services.

The supplier highlights capabilities such as quick‑turn prototyping, a range of surface‑finish options and advanced hole technologies including blind and buried vias. No further corporate history, employee count or client list is disclosed in the source data. Buyers should therefore obtain direct confirmation of production capacity, quality management certifications and any applicable environmental compliance. All service descriptions are limited to the details presented in the listing.
