The listing offers FR‑4 copper‑clad laminate offcuts sourced from Wuxi Chifeng Metal Products Co., Ltd in Jiangsu Province, China. The material consists of a woven glass‑fiber cloth substrate impregnated with flame‑retardant epoxy resin and bonded to electrolytic copper foil on one side. These offcuts conform to IPC‑4101 specifications, which define the mechanical and electrical properties required for printed circuit board substrates. The supplier provides the sheets in standard panel dimensions and a range of copper weights, making them suitable for low‑volume production.
In the PCB industry, typical FR‑4 thickness lies between 0.8 mm and 1.6 mm, with a dielectric constant near 4.5 and a glass transition temperature around 130 °C, characteristics that match the offcuts described. The copper foil is usually supplied in 1 oz/ft² (35 µm) or 2 oz/ft² (70 µm) options, both of which are common for prototype and small‑batch boards. Because the material is a surplus from panel production, it can be obtained at a lower unit cost than full‑panel purchases, while still meeting the same performance standards.
Buyers such as electronics manufacturers, prototype developers and educational labs often source these offcuts to reduce material expense for short runs or experimental layouts. Trade terms are not disclosed in the listing, so interested importers should request the minimum order quantity, pricing and preferred Incoterms directly from the supplier. Confirming the exact panel size, copper weight and any required certification documents before placing an order will help ensure the material fits the intended design.

Before placing an order, verify the exact panel dimensions, copper weight, and any certification documents such as IPC‑4101 compliance or UL94 test reports. Because the product is sold as surplus offcuts, size and weight may differ from batch to batch, so a sample or detailed specification sheet is advisable. Confirm that the material meets the thermal and electrical requirements of your design before committing to a purchase.
Importers should discuss logistics details directly with Wuxi Chifeng Metal Products Co., Ltd, including the preferred Incoterms (for example FOB Wuxi port or CIF Shanghai) and the expected lead time for shipment of offcut material. Payment terms are not listed, so negotiate terms such as T/T, L/C or open account based on mutual trust and order size. Clarifying these trade conditions early helps avoid delays at customs or the port of entry.
For quality assurance, arrange a pre‑shipment inspection that includes visual checks for delamination, measurement of thickness, and verification of copper thickness using a micrometer. Request electrical testing such as dielectric loss and insulation resistance to confirm material performance. Obtaining the relevant test reports and certificates will provide confidence that the offcuts meet your project's specifications.
