Import Copper Clad Laminate — Buy in Bulk from Supplier in China

Zhejiang Hengyu Electronic S&T Co., Ltd. offers copper clad laminate (CCL) in FR-4 grade, designed for high-performance PCB applications. The material adheres to the IPC-4101C/21 standard, ensuring thermal stability and electrical insulation critical for circuit board manufacturing. It is composed of fiberglass and copper foil, with options for single-sided or double-sided copper configurations to suit diverse manufacturing needs.

The FR-4 variant is a woven E-glass fabric epoxy laminate, known for its mechanical strength, dimensional stability, and resistance to moisture and heat. Typical properties include a dielectric constant of 4.5 to 5.2 at 1MHz, a dissipation factor of 0.02, and a glass transition temperature (Tg) of 130°C to 140°C. These characteristics make it ideal for multilayer PCBs in telecommunications, consumer electronics, and industrial controls. Standard copper foil thicknesses range from 18µm to 70µm, with typical board thicknesses from 0.2mm to 3.2mm.

Buyers source this CCL for applications requiring reliable electrical performance, such as motherboards, power supplies, and RF circuits. The supplier’s location in Zhuji, Zhejiang, positions it close to major electronics manufacturing hubs in eastern China. Confirm the exact specifications, such as Tg, dielectric properties, and flammability ratings (UL 94 V-0), as these directly impact the laminate’s suitability for high-frequency or high-temperature environments.

Zhejiang Hengyu Electronic S&T Co., Ltd. is located at No.23 Qianxi Road, Zhuji, Zhejiang Province, China. The company operates as an imported-tier supplier with a harbor trust tier, indicating a verified ability to handle international orders. Its profile does not list a response rate or average response time, so buyers should proactively reach out for inquiries.

The supplier focuses on FR-4 copper clad laminate, emphasizing compliance with IPC-4101C/21 and UL standards. While the description mentions UL, RoHS, and ISO 9000 certifications, these are not explicitly confirmed in the profile’s core data, so buyers should request documentation to verify compliance. The company caters to PCB manufacturers in electronics, telecommunications, and consumer goods sectors, but additional details like production capacity or client references are not provided.
