According to the current living habits, waterproofing has become an indispensable basic requirement in our lives. Stability and durability are the requirements for strict quality control of each product. Its components and the product itself must meet the waterproof standards of IP66, 67 or even IP68. Therefore, it is particularly important to judge whether the product can meet this standard. The airtightness test of smart watches is a rigorous integrity assessment applied to smart watches and their internal containers. The airtightness test is mainly to check whether there is leakage in the connecting parts of the smart watch and whether it can meet the waterproof level requirements.
