along withwearableThe booming development of the equipment market,Today's smart wearable devices are becoming more and more relevant to people's lives.There are many active people in all kinds of squares. If you look carefully, you will find that there are people wearing different devices among them. Smart watches are no longer a new thing.For smart watches and smart bracelets, waterproofing is a very important function: in addition to not having to take them off when washing hands and bathing, excellent waterproof capabilities can also make them suitable for professional sports such as swimming and diving.
Smart watch back cover charging contacts
Smart watches generally include an upper cover and a lower case. The upper cover and lower case are fixed to form a smart watch casing. In order to protect the electrical components in the casing,The back cover of a smart watch needs to have certain waterproof properties.The current waterproofing technology isThe joints between the upper cover and the lower shell are bonded and fixed through a glue dispensing process to form a sealed shell.This kind of waterproof structure is difficult to assemble and costly. It requires professional equipment for dispensing glue. After dispensing glue, the overflow glue needs to be manually wiped off. The labor cost is high and the work efficiency is low. After dispensing glue, the maintainability of the smart watch is poor and almost impossible to repair.
Back shell air tightness test mold
Hirays Technology has worked hard on smart watch waterproof testing, which is required for ordinary smart watches.IP68For the waterproof level, Hirays Technology uses the following testing equipment and testing plans:
Equipment used: Hirays classic series air tightness and waterproof testing equipment
Test plan: direct test method, using two procedures of high and low pressure for testing. Customize the mold according to the structure of the watch back cover. Put the watch back cover into the mold. Press the start button on the instrument and then the mold presses down to seal the watch back cover. The instrument enters the test program. First, use low pressure17KPAInflate the watch cover5S, voltage stabilization8S,test3S, leakage value0.03KPA;reuse500KPAhigh pressure to inflate the back cover of the watch8, voltage stabilization8S,test5S, leakage value0.06KPA.According to the set parameters, the change of air pressure in the product cavity is measured to determine whether the charging contact on the back cover of the watch is waterproof.For products that exceed the upper limit of the leakage value or fail to reach the test pressure, the series will automatically determineOK/NG。

So what is the role of using a combination of high and low voltage testing?Hirays Technology is here to answer your questions.
The role of using a combination of high and low pressure testing: Due to the particularity of smart watches, if high pressure is directly used 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.However, only using low voltage for testing would not meet the customer's standards.First use low pressure to test, so that leaking products can be detected in time, and then use high pressure to test to ensure that the waterproof standard of the watch can meet customer requirements.
