Problems solved by technology

At present, most copper-clad laminates use glass fiber cloth as a reinforcing material. However, the dielectric constant of glass fiber cloth is higher than that of resin substrates, and it occupies a higher volume fraction of copper-clad laminates, which directly affects the dielectric properties of copper-clad laminates.
At the same time, the laminated substrate made of alkali-free glass cloth impregnated with polytetrafluoroethylene dispersion emulsion and then hot-pressed has high insulation and high temperature resistance, but its rigidity is relatively poor, which affects the rigidity of the copper clad laminate as a substrate.

Abstract

The invention belongs to the technical field of copper clad laminates, in particular to a method for manufacturing a glass fiber cloth reinforced copper clad laminate. The prepreg is obtained, and finally the semi-cured and semi-cured copper foils are stacked, combined and pressed into copper clad laminates according to product specifications. By controlling the total integral fraction of the glass fiber cloth in the copper clad laminate, the invention adopts two prepreg treatments, reasonably controls the proportion of prepregs, and uses a silane coupling agent to perform surface treatment on the glass fiber cloth, and at the same time uses a modified ring Oxygen resin impregnated glass fiber cloth can effectively improve the rigidity, dielectric properties and insulation reliability of copper clad laminates, with reliable process and simple operation.

Description

technical field [0001] The invention belongs to the technical field of copper clad laminates, in particular to a manufacturing method of a glass fiber cloth reinforced copper clad laminate. Background technique [0002] Copper clad laminate is a kind of plate-like material formed by dipping the reinforcing material with adhesive, covering one or both sides with copper foil, and hot pressing, called Copper Clad Laminate (CCL), referred to as CCL. copper plate. Its only purpose is to make printed circuit boards (Printed Circuit Board, PCB). Reinforcing materials include cellulose paper, electronic glass fiber woven cloth, electronic glass fiber paper (non-woven fabric), synthetic fiber woven cloth, synthetic fiber non-woven fabric, and the like. The function of the reinforcing material is to make the copper clad laminate have a certain mechanical strength. [0003] With the development of high-performance, high-functionality and networking of computers and information commu...
