We have already mentioned the sealing test of smart watches before. Due to the particularity of its structure, it requires professional testing to support the security of smart watches.For manufacturers, its high sealing is conducive to production safety. For consumers, the good sealing of smart watches is conducive to ensuring its accuracy during use. In addition to conventional sealing testing, the normal use of smart watches under deep water has also become an issue of increasing concern, and the detection technology of smart watches at 50 meters underwater is becoming more and more mature.

Recently, Hirays Technology has conducted research on the deep-water sealing test of smart watches and has made considerable achievements. This time we will analyze the deep-water sealing test of smart watches.

1. Difficulties in detecting smart watches

1. Smart watches have a high degree of precision, and their waterproof performance needs to be considered during production. Therefore, they have a solid appearance and usually have no obvious gaps. During inspection, they still need to be customized according to their appearance;

2. This test is conducted to simulate the sealing condition of a smart watch 50 meters underwater. Therefore, during the test, the instrument needs to output gas with a certain pressure value for detection, and the non-destructive nature of the test must also be taken into consideration.

1. Due to the high overall precision of smart watches, indirect detection will be used this time.First of all, Hirays Technology will customize a special mold according to the shape of the smart watch. The smart watch is placed in the mold and fits the inner wall of the mold. It is more conducive to closing the mold during inspection, which is beneficial to the subsequent inspection steps;

2. Whether the smart watch can be used normally fifty meters underwater must pass the sealing test of this process.Before the test starts, certain parameters need to be set to keep the instrument stable when testing it through the pipeline; and the smart watch must be tested under a gas with a pressure equal to that of fifty meters deep water; when the upper and lower molds are closed, the instrument will input clean and impurity-free gas into the interior of the mold through the conduit;

3. When the air pressure reaches the set value, the inside of the mold will be in a constant state. At this time, the precision sensor will determine whether the gas leakage of the smart watch reaches the standard in this environment. If the sealing of the smart watch is not good, the leakage value displayed on the instrument will become larger and larger, and the pressure value will decrease at the same time.At this time, it can be determined whether the smart watch meets the standard. Its leakage value is greater than the standard, which means that the air tightness test fails.
