The FR‑4 copper clad laminate sheet supplied by Wuxi Chifeng Metal Products Co., Ltd is a glass‑fiber reinforced epoxy composite with electrolytic copper foil of 99.9 % purity. The product is offered in copper thicknesses of 18 µm, 25 µm, 35 µm and 70 µm, corresponding to approximately 0.5 oz, 0.7 oz, 1 oz and 2 oz per square foot. Board thicknesses range from 0.8 mm up to 1.6 mm, and sheet sizes are 37 × 49 in, 41 × 49 in and 43 × 49 in, with colour options of yellow or green. The laminate meets IPC‑4101 specifications for electrical performance and thermal resistance.
The material combines a glass fiber fabric substrate with epoxy resin, a construction that gives the board excellent thermal stability and machinability, qualities that are standard for electronic‑grade FR‑4 substrates. Typical industry grades exhibit a dielectric constant around 4.5 at 1 MHz and a glass transition temperature near 130 °C, which align with the performance of the sheets listed. The copper foil is applied to one or both sides, providing single‑side or double‑side configurations as required by circuit design. These characteristics make the laminate comparable to standard products sourced from major PCB material hubs.
Manufacturers of printed circuit boards for televisions, computers, communications equipment and industrial power drives commonly source this type of laminate. Importers should confirm the minimum order quantity, lead time and preferred Incoterms directly with the supplier, as these details are not disclosed in the listing. Payment terms, inspection requirements and any required certifications such as UL or IEC should also be clarified before contract finalisation. The supplier’s response rate is currently recorded as 0 %, so proactive communication is advised.

Before placing an order, verify that the laminate’s material data sheet cites IPC‑4101 compliance and includes the exact copper thickness, board thickness and sheet dimensions you require. Request a mill test report that covers dielectric constant, loss tangent, glass transition temperature and moisture absorption, especially if the boards will be used in high‑frequency or high‑temperature applications. Confirm that the colour and side configuration match your production line specifications to avoid downstream rework.
Discuss logistics early by asking the supplier which Incoterms they can offer, typical lead time from order receipt to shipment, and preferred payment methods such as T/T or LC. Because the supplier’s response rate is recorded as zero, establish a clear communication channel and agree
