Abstract

The invention relates to a high frequency-characteristic copper-clad plate manufacturing method. The method comprises the following steps: 1)a poly phthalazinone ether / epoxy resin blend is prepared; 2)a sol is prepared; 3)a prepreg is manufactured; and 4)the copper-clad plate is manufactured. As the epoxy resin is modified by poly phthalazinone ether, the manufactured poly phthalazinone ether resin-based high-frequency copper-clad plate overcomes defects such as high moisture absorption, poor processing property, poor impact-resisting property and high price of the existing high-frequency plate. In addition, the manufactured high-frequency copper-clad plate has the following advantages of excellent dielectric property and high glass transition temperature, excellent mechanical property and dimensional stability, excellent heat-resisting property, good processing property, and excellent flame-retardant property. The high-frequency copper-clad plate of the invention can meet requirements of manufacturing a high-frequency, high-speed and high-property circuit board.
