As people pay more attention to health, outdoor watches have become a must-have for businesses.In the field of smart wearables, after so many years of iterative optimization, the original tasteless image should have been abandoned long ago. Intelligence and practicality are the greatest competitiveness.

Product to be tested: watch middle frame

Growing demand for smart watches，At the same time, problems arise.When wearing a watch, you will inevitably need to wash your hands or encounter rainy days. If the smart watch gets water, it will easily cause damage to the device.Among them, the waterproof middle frame of the watch is more important.Hirays Technology will share aAir tightness and waterproof detection of watch middle framecase.

In this case, the waterproof rating of the smartwatch isIP68，Based on this level, it is possiblePrevent playing with water, bathing, and swimming in daily lifeand a series of activitiesThe problem of water entering the middle frame of the watch occurs。Hirays Technology uses the following testing equipment and solutions for the watch middle frame:

Test plan: direct test method, customize the mold according to the structure of the middle frame of the watch, put the back cover of the watch into the mold, press the start button on the instrument and then the mold presses down to seal the back cover of the watch. The instrument enters the test program. First use-17KPApressure to inflate the watch cover10S, voltage stabilization10S,test5S, leakage value0.03KPA;reuse500KPAhigh pressure to inflate the middle frame of the watch10S, voltage stabilization10S,test5S, leakage value0.06KPA.According to the set parameters, the changes in air pressure in the product's inner cavity are measured to determine the waterproofness of the watch's middle frame.For products that exceed the upper limit of the leakage value or fail to reach the test pressure, the series will automatically determineNG。

The role of using a combination of negative pressure and high pressure testing: Due to the particularity of watches, if high pressure is used directly for testing, some leaking products may be pressed together by the high pressure, making the leaking part undetectable and reducing the quality of the product.Therefore, we choose the testing method of first negative and then positive. First, use negative pressure test to detect leaking products in time, and then use high pressure regulation to test to ensure that the waterproof standard of the watch can meet customer requirements.
