Description

Technical Field

[0001] The utility model relates to the technical field of PCB boards, and in particular to a PCB board with an anti-leakage function. Background Art

[0002] The names of circuit boards include: ceramic circuit boards, alumina ceramic circuit boards, aluminum nitride ceramic circuit boards, circuit boards, PCB boards, aluminum substrates, high-frequency boards, thick copper boards, impedance boards, PCBs, ultra-thin circuit boards, ultra-thin circuit boards, printed (copper etching technology) circuit boards, etc. Circuit boards make circuits miniaturized and intuitive, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layout.

[0003] After searching, the patent with application number CN201922060846.5 discloses a PCB board with anti-leakage function. The isolation groove can form a certain space isolation zone between two components, effectively avoiding the erosion of acid, alkali and moisture, and the leakage caused by the accumulation of dust, thereby improving the one-time qualified rate of the finished circuit board test. The circuit board is installed through the isolation groove to improve the convenience of installation and enhance the anti-leakage function. However, during the installation of the circuit board, the circuit board is directly installed on the board. After the line on the circuit board is worn, it will be connected to the circuit board through the line, and finally the leakage is transmitted directly through the board, resulting in leakage. After the leakage, it will affect other equipment on the board. Therefore, a PCB board with anti-leakage function is proposed. Utility Model Content
