These offcuts provide reliable electrical insulation and thermal conductivity, with dielectric properties tailored to specific electronic design requirements. The material is supplied in standard packing formats, with flexibility for bulk orders.
FR-1 offcuts are typically phenolic-based, offering cost-effective solutions for single-sided PCBs, while FR-4 offcuts use epoxy woven glass for higher performance in multilayer boards. CEM-1 and CEM-3 are composite laminates combining paper and glass fibers for balanced mechanical and electrical properties. Typical industry values for FR-4 include a dielectric constant of 4.5 at 1 MHz and a glass transition temperature of 130°C.
These offcuts are used in computers, telecommunications, automotive electronics, and industrial control systems, where space efficiency and material consistency are critical. Withus International, based in Incheon, South Korea, offers these materials for global supply chains, with standard packaging and trade terms available upon request.

Before ordering from Withus International, verify the grade of copper clad laminate offcut and its specific properties, such as dielectric constant, glass transition temperature, and flame retardancy. Request material safety data sheets and test reports to confirm compliance with your application’s standards, especially for FR-4 or CEM-3 used in high-reliability sectors like automotive or telecommunications.
Clarify logistics details including lead time, Incoterms (e.g., FOB Busan or CIF to your port), and payment terms. South Korea’s primary export port for such materials is Busan, so confirm loading and shipping schedules. Discuss packaging requirements to prevent damage, as offcuts may have irregular shapes and sizes.
Quality checks should include visual inspection for delamination, copper cladding defects, or resin voids. For FR-4 offcuts, test the dielectric constant using ASTM D150 and verify the glass transition temperature with differential scanning calorimetry (DSC). Request a certificate of conformance for UL 94 V-0 flame retardancy and ISO 9001 quality management standards where applicable.
