A kind of high frequency copper clad laminate and preparation method thereof |
| abstract |
The invention relates to a high-frequency copper-clad laminate and a preparation method thereof, so as to solve the problems of complicated process and material pollution in the production process of the existing high-frequency copper-clad laminate. The high-frequency copper clad laminate includes a glue-coated copper foil and a prepreg, and the glue-coated copper foil and the prepreg are alternately stacked in sequence. The preparation method of the above-mentioned high-frequency copper clad laminate includes the following steps: cleaning up the steel plate, the bearing plate, the upper buffer pad and the lower buffer pad; placing the lower buffer pad in the middle position of the bearing plate, and then placing the steel plate on the lower buffer pad; Place the glue-coated copper foil on the center of the steel plate with the rough side up and lay it flat; place the prepreg and glue-coated copper foil alternately in turn according to the set number of layers, and then place the upper buffer on the prepreg and glue-coated copper foil. Put the steel cover on the center position of the machine; set the pressing program of the hot press; send the material into the hot press; start the hot press, and the hot press will be processed to high frequency according to the set parameters through vacuum, heating and hydraulic processes. Finished copper clad laminate. |
