FR4 board, also known as FR4 sheet or fiberglass sheet, is a laminate made from glass fibre reinforced epoxy resin. The material offers a combination of high mechanical strength, flame retardancy and stable dielectric properties suited for printed circuit board (PCB) fabrication. Shenyang Youda Insulation Materials Co., Ltd. supplies the sheets in both standard 4 × 8 ft (1220 × 2440 mm) sizes and custom dimensions on request. Thickness options range from 0.5 mm to 3.0 mm, allowing designers to select the appropriate profile for their electrical requirements.
The epoxy‑glass construction gives a typical dielectric constant of 4.5 and a loss tangent around 0.02 at 1 MHz, which aligns with industry expectations for multilayer boards. Typical tensile strength is about 30 000 psi, and the sheets meet flame‑rating standards such as UL94 V‑0, providing reliable fire safety. The product is reported to comply with ISO and CE certifications, indicating adherence to recognised quality and safety norms. Standard packaging involves bundling the panels in wooden crates with protective film to prevent edge damage during transport.
Manufacturers of electronic assemblies, automotive electronics and industrial control equipment commonly source these FR4 sheets for their durability and electrical performance. The supplier offers FOB and CIF shipping terms, but exact incoterms, MOQ and lead‑time are not disclosed and must be verified with Shenyang Youda Insulation Materials Co., Ltd. Buyers should request a material test report, dielectric breakdown voltage data and a weight certificate for each batch. Confirming payment schedule, inspection point and any required export documentation with the supplier will help smooth the import process.

Before confirming a purchase, verify the exact thickness, sheet size and any custom dimensions to ensure compatibility with the intended PCB stack‑up. Request the material test report and dielectric breakdown voltage data to confirm that the electrical performance meets design requirements. Checking the supplier’s ISO and CE compliance certificates will also reduce risk of non‑conformity during import.
Logistics planning should include confirming the preferred Incoterm, expected lead‑time and the destination port. Because the listing does not disclose MOQ or payment terms, ask the supplier to detail FOB or CIF options, payment schedule and any required documentation for customs clearance. Aligning these details early helps avoid unexpected delays and costs.
Arrange a pre‑shipment inspection that checks panel flatness, edge quality and packaging integrity against the agreed specifications. Request a weight certificate and verify the presence of fire‑rating labels on the sheets. Maintaining records of these quality checks will support smooth customs clearance and provide a basis for any future warranty claims.
