Airtightness Test for Intelligent Wearings

In this era of rapid development of science and technology, people are increasingly inseparable from electronic products that can bring convenience to people. The smart bracelet is one of them. Shenzhen in September is changeable and hot. In this hot climate, people often sweat, and the smart bracelet they often wear is also the most vulnerable to sweat.

Product to be tested: middle frame of smart bracelet

Water is the enemy of electronic products. Whether it is sweat, rain or domestic water, its service life will be shortened after invasion. Therefore, for people who are prone to sweating or often like outdoor sports, the waterproof function of the smart bracelet is extremely important. Today we will take a look at the case of air tightness and waterproof detection of the middle frame of the smart bracelet.

Waterproof detection mold for the middle frame of the smart bracelet

The customer requires that the middle frame of the smart bracelet should be waterproof to IP68. According to the requirements, Unielmeasurement has used the following equipment and solutions:
Solution: adopt direct test method, with test pressure of 500KPA, inflation time of 10S, pressure stabilization time of 10S, test time of 5S, and upper leakage limit of 0.09KPA. The test mold is designed according to the structure of the middle frame of the bracelet. The mold is used to seal the upper and lower sides and the periphery of the bracelet. The instrument inflates the periphery of the bracelet according to the set parameters, stabilizes the pressure, and tests. OK or NG is determined by monitoring the change of air pressure.
