Abstract

The invention provides a halogen-free thermosetting resin composition, a prepreg comprising the same, a laminated board and a printed circuit board. The halogen-free thermosetting resin composition comprises the following substances serving as necessary components, in 100 parts of organic solid matters by weight: (A) 35-65 parts of halogen-free epoxy resin; (B) 10-35 parts of poly-phosphonate; (C) 10-30 parts of cyanate ester. The halogen-free thermosetting resin composition, the prepreg comprising the same, the laminated board and the printed circuit board have high glass transition temperature, excellent dielectric property, high peeling strength, high heat resistance, low water absorption and good process machinability, can realize halogen-free flame resistance and reach UL94 V-0.

Description

technical field [0001] The invention relates to the technical field of copper clad laminates, in particular to a halogen-free thermosetting resin composition and prepregs, laminates and printed circuit boards containing it. Background technique [0002] With the high-speed and multi-functionalization of electronic product information processing, the application frequency continues to increase, and 3-6GHz will become the mainstream. The substrate material will no longer play the role of mechanical support in the traditional sense, but will become a PCB and terminal together with electronic components. An important way for manufacturers and designers to improve product performance. Because a high Dk will slow down the signal transmission rate, and a high Df will cause the signal part to be converted into heat energy and be lost in the substrate material, so reducing Dk / Df has become a hot pursuit of the substrate industry. In this context, cyanate ester resins with excellent ...
