In this paper, the micro dissection technology of printed circuit board and its application are discussed in detail. Scope: Jia - Bao Yue - Theme: plate, copper plate hole without adverse side, One, 200 times The quality of the boards used in the PCB will directly affect the quality of the boards and the quality of the products. Heavy impact on product quality. Figure 1.2.3.4 is the fact that the printed board hole is not copper scrap due to plate factors. The fact that there is no copper scrap. Figures two, 100, two, Analysis: Figure 1.2. When the microscope is enlarged 100 times, it is found that the resin is very loose, and there is an empty hole. It is found that the resin is loose and has voids. Two, in drilling, the high-speed rotation of the drill knife will inevitably move loose resin, resulting in rough hole wall, measurements will pull loose resin, resulting in rough hole wall, 1.2 roughness of 66 - 99UM. Roughness exceeding standard, 66 - 99UM. Roughness roughness requirements
