Import Cu-Pcb — Buy in Bulk from Supplier in China

Cu-PCB from Shenzhen Chuangsanxin Technology Co., Ltd. is a printed circuit board constructed with a pure copper substrate measuring 69mm x 69mm and a thermal conductivity of 400 W/m·K. This design eliminates the need for aluminum or FR-4 heat spreaders in high-power electronics, offering direct thermal dissipation from components to the board surface. The material is not clad or laminated - it is solid copper, optimized for thermal management in compact devices.

The copper substrate is electrochemically refined to ensure high purity, reducing impurities that can degrade thermal performance. Unlike standard PCBs with dielectric layers, this variant has no insulating substrate beneath the copper, allowing direct mounting of heat-generating components. This construction is typical in high-efficiency LED drivers, power amplifiers, and electric vehicle controllers where thermal runaway must be prevented.

Buyers include manufacturers of industrial power supplies, automotive electronics, and telecom base stations requiring compact, high-reliability thermal solutions. Orders are typically placed in panels of 10 to 50 units, with custom dimensions available on request. The supplier does not specify minimum order quantity, plating finish, or surface treatment in public data. Buyers must confirm copper thickness, flatness tolerance, and surface roughness before production.

Shenzhen Chuangsanxin Technology Co., Ltd. is located in Shajing Street, Bao'an District, Shenzhen, China, and operates as a manufacturer of copper-based printed circuit boards. The supplier's profile indicates a harbor trust tier and imported supplier classification, suggesting formal export registration. No details are provided on factory size, production capacity, workforce, or certifications. The listing offers no client references, export history, or quality control documentation.

The supplier does not claim ISO certification, RoHS compliance, or any third-party testing. All technical claims, including thermal conductivity, are presented without supporting data sheets or test reports. Buyers should treat the 400 W/m·K value as a product specification and request independent verification before production. Communication response rates are unavailable, indicating direct inquiry is necessary for technical confirmation.
