Product Description
Copper clad laminated sheets
Clad in Copper Laminate sheets are produced by pressing membranes of filler material impregnated with specially formulated phenolic resins under high pressure and heat and then bonding the layers together with electro-deposited copper foil to form a thermoset composite material. Provides good electrical, mechanical, moisture, and heat resistant qualities and can be used for hot and cold punching applications. Environmental elements such as humidity, temperature, corrosive atmosphere, and other factors impact the mechanical and electrical properties of copper-clad laminated sheets, among other things.

Their composition minimizes risk during operation, making them an optimal choice for manufacturers prioritizing both electronic performance and user safety.
Robust Construction & Reliable PerformanceEach sheet features a standard 35 m copper finish bonded to an industrial-grade epoxy resin with fiberglass, ensuring excellent dielectric strength and outstanding electrical insulation. The material structure supports high tensile strength and reliability, critical in PCB manufacturing and high-performance electronic assemblies.
Multi-Industry Applications & CustomizationPerfectly suited for PCB fabrication, electrical insulation, and prototyping, these sheets are widely used in electronic industries across India and beyond. With custom sizes available, manufacturers can tailor sheet dimensions for specialized requirements, enabling greater flexibility and efficiency in production processes.
FAQs of Copper clad laminated sheets:
Q: How are these copper clad laminated sheets manufactured for optimal quality?
A: The sheets are manufactured using a high-pressure heat bonding process, which firmly laminates electrolytic copper foil onto an epoxy resin base reinforced with woven fiberglass. This ensures consistent thickness, high bonding strength, and a smooth, burr-free edge finish.
Q: What are the main benefits of using these sheets in PCB manufacturing?
A: These sheets provide high dielectric strength, moisture and corrosion resistance, and excellent solderability, which are essential for ensuring durability and reliable performance in printed circuit board (PCB) applications. Their flame-retardant nature further enhances device safety.
Q: Where are copper clad laminated sheets commonly applied?
A: These sheets are primarily used in the fabrication of PCBs for electronic devices, circuit prototyping, electrical insulation, and various electronic equipment. Their quality and features meet the rigorous demands of industrial, commercial, and consumer electronics.
Q: What makes these sheets suitable for high-moisture environments?
A: Featuring moisture absorption under 0.02% and high insulation resistance, the sheets perform reliably even in humid conditions. The epoxy resin and fiberglass substrate also contribute to their high moisture and heat resistance.
Q: When should I consider requesting custom dimensions for these sheets?
A: Custom dimensions are ideal when standard 1200 x 900 mm sheets do not fit your specific project or production line requirements. Custom sizing optimizes material utilization and reduces manufacturing waste during PCB fabrication or electrical assembly.
Q: What process ensures the copper surface remains oxidation-resistant?
A: An optional anti-oxidation coating can be applied to the copper surface. This surface treatment helps prevent oxidation and corrosion, extending the sheets shelf life and improving long-term reliability in electronic assemblies.
Q: Are these copper clad laminated sheets compliant with environmental standards?
A: Yes, they comply with RoHS regulations, minimizing hazardous substances in their construction. Additionally, these sheets are recyclable, supporting sustainable and environmentally responsible manufacturing practices.
