Problems solved by technology

However, this manufacturing method must use flame retardants containing halogen (such as bromine), such as tetrabromocyclohexane, hexabromocyclodecane, and 2,4,6-tris(tribromophenoxy)-1 , 3,5-Triazabenzene, and these bromine-containing flame retardants are easy to cause pollution to the environment when the product is manufactured, used, or even recycled or discarded

Abstract

The invention provides halogen-free resin composition, and a copper clad laminate and a printed circuit board applying the halogen-free resin composition. The halogen-free resin composition comprises, by weight, (A) 100 parts of epoxy resin, (B) 1 part -100 parts of benzoxazine resin, (C) 1part -100 parts of styrene maleic anhydride, (D) 0.5 part -30 parts of amine curing agents, and (E) 5-150 parts of halogen-free flame retardants. By means of the specified constituents and ration, the halogen-free resin composition achieves the purposes of low dielectric constant, low dielectric loss, high heat resistance, and high flame resistance, can be manufactured into semi-solidified rubber pieces or resin films, and then achieves the purposes of being applied to the copper clad laminate and the printed circuit board.

Description

technical field [0001] The invention relates to a halogen-free resin composition, in particular to a halogen-free resin composition applied to copper foil substrates and printed circuit boards. Background technique [0002] In response to the world's environmental protection trends and green regulations, Halogen-free is the current environmental protection trend of the global electronics industry. Countries around the world and related electronics manufacturers have successively established mass production schedules for halogen-free electronic products. After the implementation of the European Union's Restriction of Hazardous Substances (RoHS), substances including lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls and polybrominated diphenyl ethers are no longer used in the manufacture of electronic products or its components. Printed Circuit Board (PCB) is the basis of electronic and electrical products. Halogen-free PCBs are the first priority to be re...
