Copper Clad Laminate Sheet CEM3 from Wuxi Chifeng Metal Products Co., Ltd is a flame retardant glass fiber epoxy composite, bonded with electrolytic copper foil on one or both sides. The supplier offers standard sheet dimensions of 40 by 48 inches with thicknesses of 0.8 mm, 1.0 mm, 1.2 mm, 1.6 mm, and 2.4 mm, and copper foil options of 18 µm, 25 µm, 35 µm, and 70 µm. The material is supplied in white or yellow, with the epoxy resin formulation designed to meet electronic grade requirements for PCB manufacturing.
The laminate is reinforced with bleached glass fiber cloth, which provides mechanical strength and dimensional stability, while the flame retardant epoxy resin ensures compliance with safety standards typical for consumer electronics. CEM-3 is a standard grade in the industry, known for its balance of electrical insulation, thermal resistance, and machinability, making it a common choice for multi-layer circuit boards. Its low bow and twist characteristics reduce warping during processing, which is critical for high-precision applications.
This material is primarily used in the production of printed circuit boards for computers, telecommunications devices, and high fidelity audio equipment. Buyers typically source CEM-3 in bulk sheets for industrial applications, with trade terms and packaging tailored to the PCB supply chain. The supplier’s location in Wuxi, Jiangsu Province, positions it within a major hub for electronic materials manufacturing and export, facilitating logistics for international buyers.

Before placing an order, verify the exact specifications of the CEM-3 sheets, including thickness, copper foil thickness, and dimensional tolerances, to ensure they match your production requirements. Confirm whether the supplier provides certificates of conformity or test reports for the material, as these documents are essential for quality assurance in PCB manufacturing.
Logistics details such as lead time, shipping methods, and Incoterms should be clarified with the supplier. CEM-3 sheets are typically shipped as flat panels, so discuss packaging and handling procedures to prevent damage during transit. For international shipments, ensure that all customs documentation and import regulations for electronic materials are addressed.
Conduct quality checks upon receipt, including visual inspection for defects, dimensional verification, and electrical insulation tests if applicable. For critical applications, consider third-party inspection services to validate the material’s compliance with industry standards. Request the supplier’s recommended storage conditions to maintain the material’s properties before use.
