CEM-3 CCL from Wuxi Chifeng Metal Products Co., Ltd is a flame-retardant glass epoxy copper clad laminate designed for PCB applications, combining bleached fiberglass cloth with flame-retardant epoxy resin and electrolytic copper foil. The material is supplied in standard sheet sizes of 40x48 inches with board thicknesses of 0.8 mm, 1.0 mm, 1.2 mm, 1.5 mm and 1.6 mm, and copper foil options of 18 µm, 25 µm, 35 µm or 70 µm. Available in white or yellow, it balances electrical performance with cost efficiency for mid-range electronics manufacturing.
The laminate’s composition delivers high dielectric strength and dimensional stability, with low bow and twist characteristics that suit high-precision PCB fabrication. Typical industry use includes consumer electronics like computers and audio devices, where its flame retardancy meets UL 94V-0 standards and its mechanical strength supports multi-layer board designs. As a mid-tier alternative to FR-4, it offers a standard TG (glass transition temperature) of 120-130°C, which is typical for general-purpose applications.
This product is primarily sourced by manufacturers of automotive control units, industrial equipment and consumer electronics seeking a reliable, cost-effective base material. Trade terms often include MOQs based on pallet quantities, with packaging in moisture-barrier cartons to prevent delamination during transit. Buyers typically confirm copper thickness tolerances and dielectric constant values before bulk orders, as these directly impact signal integrity in high-frequency applications.

Before placing an order, verify the supplier’s UL 94V-0 certification for flame retardancy, as this is a non-negotiable requirement for most electronics applications. Additionally, request test reports for dielectric strength, peel strength, and glass transition temperature to ensure the material meets your PCB design specifications. Confirm whether the copper foil thickness and board thickness tolerances align with your manufacturing tolerances.
Discuss logistics details such as Incoterms (FOB, CIF, or CFR) and port of loading, as Wuxi’s proximity to Shanghai or Ningbo ports may offer cost advantages. Lead times for CEM-3 CCL typically range from 4 to 8 weeks, depending on order volume and custom specifications, so factor this into your production schedule. Clarify whether the supplier can provide partial shipments or requires full container loads.
Conduct incoming quality checks for dimensional stability, bow and twist, and copper foil adhesion upon receipt. Use industry-standard test methods like IPC-TM-650 for peel strength and ASTM D150 for dielectric constant to validate performance. Ensure all documentation, including material safety data sheets (MSDS) and certificates of conformity, is provided with the shipment to avoid delays in customs clearance.
