Advantages of using shrapnel microneedle modules

　　In LCD screen testing and OLED screen testing, mobile phone LCD screen test fixtures and mobile phone OLED screen test connectors are very important, but too many companies ignore the importance of display screen testing, but they do not know that display screen testing is also linked to quality . The production process of LCD screens is very mature. In contrast, domestic OLED screens are currently in the development stage. In addition to the technical difficulties to be overcome, more of them want to reduce costs, improve product yield and production capacity, which highlights The importance of display testing.

　　In the LCD screen production process, most manufacturers pay great attention to product quality and efficiency. Of course, quality and efficiency are definitely two key indicators, because quality determines the manufacturer's shipment quality, and efficiency determines the manufacturer's production speed. Both It constitutes the core competitiveness of LCD screen enterprises. However, at present, domestic LCD screen manufacturers often only pay attention to the introduction and use of production equipment, but ignore the introduction of testing equipment, especially the latter, product quality control is still mainly completed by manual testing.

　　Although some manufacturers focus on product testing, in the testing of LCD screens and OLED screens, most manufacturers only focus on the electrical performance inspection of the display screen, the appearance inspection of the display screen, and the size inspection of the display screen; of course, these are definitely true , but after these tests, there are still more or less display screens after they leave the factory, and even to consumers, there are still various display problems, causing customers to complain or even claim for quality problems, so what is the problem? Although there may be various possibilities, there may also be problems with the display test connector.

　　In the test of LCD screen or OLED screen, the display test connector needs to be used, but most manufacturers still use the pogopin probe module for testing. Unusable, and the performance of pogopin in the pitch≤0.02mm field is also very poor, or even unusable. The existence of these problems makes the stability of the connector relatively poor. Based on the above situation, KZT Kaizhitong Microelectronics independently developed a high-current BTB/FPC shrapnel microneedle module to help companies provide better test solutions in test connectors or test fixtures. The high-current shrapnel microneedle module is integrally formed, which can cope with smaller pitches, has high test efficiency, high stability, can withstand a maximum current of 50A, and has a longer service life. The contact shape and overall height can be easily made according to customer requirements. There are also special corresponding methods for female BTB connectors, which are stable and reliable.
