The application of board to board connector in mobile phone basically focuses on the battery, screen, camera, fingerprint module, headset, button, and pressure button of the mobile phone. Linear motor and other components. Board to board connector has a stable electrical transmission and connection function and is an indispensable electronic component of a mobile phone. With the development of 5g technology, the hardware of mobile phone motherboards is constantly upgraded, including the development of three cameras and four cameras of mobile phone. The consumption of board to board connectors in mobile phone is also increasing. About 1 ~ 3 pairs of board to board connectors can be added for mobile phone, and 1 ~ 2 pairs of the board to board connectors need to be added for 5g antenna.

The use of the board to board connectors for Android phones is about 17.8 pairs, and most of Apple phones are 22 pairs, accounting for half of the use of internal connectors for mobile phones! It can be seen that the application of 5g Network + mobile phone multi camera and the new exchange trend directly drive the market demand for board connectors. In the field of mobile phones, the market situation of the board to board connectors in 2022 is very good.

As the board to board connector is widely used in mobile phones, its performance requirements are of course very strict. The board to board connectors used in mobile phones not only have strict technical requirements in production but also all raw materials are required to be particularly high-precision. Testing is the best way to check the quality and performance of connectors. The multi board connector in the mobile phone board is mainly small spacing and high current. It needs to adapt to small spacing and high current transmission and test the module of the multi board connector.

In the seat test of the board to board connector, sawtooth shrapnel can be used for the connection. In the seat test that plays the role of stable connection, pointed shrapnel can be used to maintain long-term stable contact. The good rate of the seat test is 99.8%, with excellent performance. The high current shrapnel micro pin module can test 4-8 pairs of the board to board connectors at the same time. The shrapnel head can be fully contacted with the male and female seats of the board to board connector. Different head types can also be applied according to the characteristics of the male and female seats to achieve correct connection and positioning.

In the small spacing, the high current shrapnel microneedle module can handle the minimum spacing value of 0.15mm, with good stability, no pin jamming, continuous needle current transmission, and can carry 50A high current at most. The current circulates in the same material, the voltage is certain, there is basically no current attenuation, and the connection performance is stable. The floating plate of high current shrapnel micro pin module adopts a special limit frame design. At the same time, it tests the multi board to board connector of mobile phones to ensure horizontal movement, automatically correct the deviation and ensure the stable connection between shrapnel and connector.

In addition to the above advantages, the average service life of the high current shrapnel microneedle module is 20W, which does not need continuous use and replacement, avoids material waste, greatly improves the simultaneous test efficiency of the mobile phone multi board to board connector, reduces the test cost, solves the test problems, and realizes the optimization of the test scheme.
