A brief analysis of the development direction of watch manufacturers

①True smart watch

Technological innovation and product iteration have improved user experience, and consumers are increasingly favoring smarter and more integrated health monitoring and exercise tracking functions.As 5G technology becomes more popular and AI functional applications expand, these will stimulate emerging markets and becomeAn important reference for customers to make purchase choices.

②Higher requirements in professional fields

The demand for health monitoring and exercise tracking is deepening, and the demand for specific scenarios is increasing.Smart watches require a certain degree of dust-proof and waterproof, while professional-grade sports smart watches have a higher pursuit of dust-proof and waterproof.

Note: 1ATM=100kPa≈10 meters water depth

       5ATM=0.5Mpa≈50 meters water depth

Pay more attention to sealing testing and optimize structural design

During the actual communication process with customers, Hirays summarized the changes in the manufacturer's philosophy, namely:Optimize structural design,Pay more attention to seal detection。

Here’s why:

↑SmartThe part of the watch to be tested (rendering)

1. Middle frame incoming material air tightness test: mainly detects the sealing condition between the buttons and the middle frame, and customizes the jig to seal the TP (screen) dispensing surface/rear shell dispensing surface.

2. Front shell module air tightness test: used to test whether the seal between the TP and the middle frame is qualified, and a custom jig is used to seal the dispensing surface of the rear shell.

3. Back shell incoming material air tightness test:Check the sealing degree between the TP and the middle frame to meet the standard, and use a customized jig to seal the glue dispensing surface of the rear case.

4. Air-tightness test of the rear shell heart rate mirror: Check whether the seal between the heart rate mirror and the rear shell is qualified, and use a customized jig to seal the speaker hole, MIC hole, barometer hole, balance hole, and rear shell dispensing surface.

5. Air tightness test of back shell components: Test the air tightness of back shell components such as barometer, speaker, charging pile, heart rate mirror, etc., and seal the MIC hole, balance hole, and back shell dispensing surface with a customized jig.

Links 1-5 all adopt the testing method of semi-finished products combined with high and low pressure. The testing instrument is HC-D high-precision differential pressure instrument. The low-pressure test pressure is 30KPa, and the leakage value shall not exceed ±30Pa; the maximum pressure test pressure is 12.5MPa, and the leakage value shall not exceed ±100Pa (60pa in the mold factory).
