Import Fr-4 — Buy in Bulk from Supplier in China

Shenzhen Hong Yunlai Electronic Technology Co., Ltd. offers FR‑4 laminate sourced from China, presented with a range of surface finishes that include OSP, shen jin, shen tin, shen silver, lead‑free, spray tin, and nickel‑gold plating. The supplier can produce boards with two to sixteen copper layers, allowing flexibility for simple single‑sided designs up to complex multilayer assemblies. Each panel is packed in a cardboard box lined with waterproof paper, protecting the material from moisture during transit.

FR‑4 is the industry standard glass‑reinforced epoxy laminate, characterised by a dielectric constant around 4.5 typical and a glass transition temperature of about 130 °C typical, making it suitable for most commercial electronics. Typical copper thickness for such laminates is 35 µm standard, providing reliable current‑carrying capability. The minimum trace width and spacing offered are 0.076 inches, matching fine‑line fabrication capabilities used in high‑density interconnects.

The material is commonly used for consumer electronics, automotive control units, and industrial control panels, where reliable electrical performance and thermal stability are required. Importers usually target OEMs, contract manufacturers, and PCB assembly houses that need consistent quality across large volumes. Since the listing does not disclose minimum order quantities, exact pricing, or lead‑time, interested buyers should contact the supplier directly to obtain a quotation and confirm trade terms.

Shenzhen Hong Yunlai Electronic Technology Co., Ltd. is located in the Baoan District of Guangdong Province, China, with the registered address Shen Cai Building 402, Fuyong Town, 518103.
