Front Screen Glass lens for iphoneX with OCA

                                                                                      The characteristics of the capacitive touch screen

The touch screen of a mobile phone can be operated by direct touch. The characteristics of the capacitive touch screen are ① can sense the human body current ② cannot be operated when wearing gloves ③ resistant to water stains, oil stains and other pollutants ④ requires frequent calibration ⑤ external inductance or magnetism When sensitive, it will make the touch screen malfunction.

This determines the necessity of mobile Phone Touch Screen reliability testing. The mobile phone touch screen reliability test project can be divided into three parts: optical & electrical performance test, mechanical performance test and environmental reliability test. In the test, a shrapnel microneedle module that can play a connecting role is needed to ensure the stability of the mobile phone touch screen test.

The one-piece gold-plated and hardened shrapnel microneedle module can exert excellent performance in the mobile phone touch screen test. In the mobile phone touch screen test, the shrapnel microneedle module can not only provide a stable connection function, but also transmit a large current. In the range of 1-50A, the current transmission of the shrapnel microneedle module is very stable, there is no current attenuation, and the overcurrent capability is strong. In addition, the shrapnel microneedle module also has a reliable solution for small pitches. The value range is between 0.15mm and 0.4mm, and the average service life is more than 20W times. The performance and adaptability are very good. . With the shrapnel microneedle module for mobile phone touch screen testing, the test efficiency has also been greatly improved, which is stable, reliable and efficient.
