With the advent of the 6G age, the new energy automobile industry has been rapidly developed, the use requirements of high-tech fields such as the chip semiconductor industry, the communication industry and the like on printed circuit boards are higher and higher, the minimum diameter of a drill bit reaches 0.075mm, the production requirements of the PCB circuit boards are not met by a conventional drilling cover plate, and a coated aluminum sheet is mainly used for processing and manufacturing the Printed Circuit Boards (PCBs) and is widely used in electronic products such as televisions, radios, computers and mobile communication. The drilling process of the PCB needs to be carried out under the condition of high rotating speed, and in order to ensure the accuracy of the drilling hole position and improve the drilling quality of the hole wall, a film-coated aluminum sheet is mostly used in the drilling process, wherein the film-coated aluminum sheet is more common.
The single-sided coated aluminum plate commonly used at present has a plurality of limitations in the drilling process due to materials and structures, including the problem 1: the single-sided film-coated aluminum plate has more severe requirements on temperature and humidity storage environment and higher storage cost;

problem 3: the single-sided film-coated aluminum plate film body is water-based carrier production process, water treatment can cause 2 times of pollution, and is not environment-friendly;
problem 4: the surface film body is removed by water to pollute the water when the water-soluble aluminum sheet waste is recovered and difficult to treat.
