a copper clad laminate is introduced . cyclic olefin copolymer fabric functions as a base fabric for manufacturing the copper clad laminate to reduce dielectric constant and dissipation factor of the copper clad laminate . the flame - retarded curing agent included in the resin for use in manufacturing the copper clad laminate is halogen - free and does not cause environmental pollution . the cyclic phosphate structure of the flame - retarded curing agent enhances thermal stability and chemical stability of the copper clad laminate thus manufactured . during the manufacturing process of the copper clad laminate , an annealing process is performed while thermal curing and lamination is taking place to prevent bending otherwise resulting from a difference in thermal expansion coefficient between cyclic olefin copolymer fabric and glass fiber fabric .
