Problems solved by technology

The main specifications are 7637, 7630, 7628, 7615, 1506, 2116, 2113, 3313, 1080, 106, 104, which are mainly used in the manufacture of copper clad laminates, but the high temperature resistance and corrosion resistance of existing electronic cloths still cannot meet our requirements. requirements, and in the actual processing of electronic cloth, folding operations often occur, so the coating is worn when the electronic cloth is folded and rubbed, resulting in serious wear of the electronic cloth coating but the operator is not clear, which will not only increase the The processing cost of copper clad laminates reduces the yield, and there are certain safety hazards. Therefore, the quantitative detection of the surface coating of electronic cloth has also become a problem that we need to pay attention to.
