Problems solved by technology

The method disclosed in this technology has complicated process and high cost, and the thickness uniformity of the prepared substrate is difficult to control, the appearance is not smooth, and it is difficult to make high-layer PCB boards.
U.S. Patent No. 2539329 mentioned the method of pretreating PTFE glass fiber cloth paint sheets at 205 °C, rolling and then impregnating to improve the "mud crack" phenomenon caused by excessive thickness of PTFE coating. It is easy to fall off when dipping, and it is difficult to laminate at temperatures below 250°C

Description

technical field [0001] The invention relates to the field of electronic product materials, in particular to a fluorine-substituted vinyl polymer resin composition, a prepreg and a laminate. Background technique [0002] With the increasing development of wireless networks and satellite communications, information products are moving towards high speed and high frequency, and communication products are moving towards the standardization of voice, video and data through wireless transmission with large capacity and fast speed. Therefore, electronic products tend to be thinner and smaller, and are suitable for high-frequency transmission, and the wiring of circuit boards is becoming more dense and multi-layered. [0003] In order to maintain the transmission rate and maintain the integrity of the transmission signal, the substrate material of the circuit board must have a low dielectric constant (dielectric constant, Dk) and dielectric loss (also known as loss factor, dissipati...
