[0003] When conducting hardness tests on existing solder resist films, it is necessary to manually use a variety of test pens of different hardness to scrape the solder resist film on the surface of the PCB circuit board. The process is rather cumbersome and it is not convenient to conduct chemical corrosion resistance and hardening degree tests at the same time, resulting in a slower testing process. In addition, there are many testing tools, which are not convenient to store and organize. Utility Model Content
