CCL FR4/CEM-3 Copper Clad Laminated Sheet
The CCL FR4 and CEM-3 copper clad laminated sheets from Ztelec Group are glass fiber reinforced epoxy composites bonded with electrolytic copper foil of 99.99% purity. FR4 provides UL 94 V-0 flame retardancy and dielectric strength of 14-18 MV/m, while CEM-3 offers a cost-effective alternative with comparable electrical properties for multilayer PCB applications. Both variants are manufactured via hot pressing of prepreg sheets coated with copper foil on one or both sides, ensuring consistent thermal stability up to 130°C for FR4 and 105°C for CEM-3.
FR4 sheets typically use 106, 1080, or 2116 glass fiber styles with resin content of 40-50%, while CEM-3 substitutes the core with cellulose paper for weight reduction. Copper foil thickness ranges from 18µm to 70µm, with standard surface treatments like HASL, ENEPIG, or OSP applied post-fabrication. Industry-standard tolerances for thickness are ±0.05mm, with copper weight deviation limited to ±10% of nominal values.
These laminates serve as the base material for single-sided, double-sided, and multilayer PCBs in consumer electronics, automotive ECUs, and telecom infrastructure. Buyers typically source full sheets of 1220x1830mm or 1000x1200mm, with MOQs starting at 50 sheets per grade. Lead times for standard grades are 20-30 days from Zhengzhou port, with FOB or CFR Incoterms commonly used for bulk shipments.

Sourcing CCL FR4/CEM-3 Copper Clad Laminated Sheet from Ztelec Group - China Import Guide
Before ordering, verify the exact glass fiber style and resin content for your application, as these directly impact mechanical and electrical performance. Confirm whether the laminates meet your required flame retardancy standards, such as UL 94 V-0 for FR4, and request test reports for dielectric strength and thermal stability if not provided.
Clarify logistics details, including lead times for your specified grade and quantity, as these can vary based on copper foil thickness and sheet size. Standard lead times are 20-30 days from Zhengzhou port, but custom specifications may extend this. Discuss Incoterms (FOB or CFR) and payment terms upfront to avoid delays in shipment.
Inspect incoming sheets for thickness uniformity, copper weight deviation, and surface defects using industry-standard gauges. Request certificates of conformance for copper purity (99.99%) and flame retardancy. For critical applications, perform additional tests such as peel strength and solderability to ensure the laminates meet your PCB fabrication requirements.
