China is the largest connector Market in the world. BTB connectors are widely and intensively used in the field of mobile phones. They are mainly used for testing LCD, OLED screen, 3C lithium battery and camera. The process of 5g construction is faster and faster. In the era of nationwide network, mobile phone iteration speed is fast, and the requirements for connectors are also higher and higher.
At present, all kinds of consumer electronic products using connectors have integrated miniaturization, thinness and high performance, which promotes the development of the corresponding connectors to be short and the connecting parts to be narrow.
In view of the characteristics of small spacing and large current of BTB connector, KZT has developed a high current shrapnel micro pin module blade pin, which can perfectly adapt to BTB connector. The high current shrapnel micropipette module adopts high-precision mold opening, and the test module is standardized, which subverts the multi-component structure of the traditional probe module. The shrapnel type structure is adopted, and the minimum pitch value that can be adapted in the small pitch field can reach 0.15mm, with stable performance and outstanding performance.
The test of BTB connector shows that high current shrapnel micro pin module has obvious advantages
The high current shrapnel microneedle module is made of nickel alloy / beryllium copper, which has the characteristics of high precision, durable wear resistance. In the BTB test project for high current, the rated current is 3a, and the maximum constant current test can withstand 50A. During the test, the current is concentrated in the same material, the resistance is constant, the electrical property is stable, and there is almost no current attenuation.
High current shrapnel micro pin module is not only outstanding in the test of large current and small spacing, but also has a unique way to deal with the BTB connector male and female seat test. During the test, the male and female seats of BTB connector are tested with shrapnel of different head types. Sawtooth type is used for BTB male test, and pointed type is used for BTB female test.
BTB male seat test: the serrated shrapnel contacts the top shrapnel of BTB connector, and the micro pin module shrapnel contacts the top shrapnel of BTB connector at multiple points to ensure the contact stability. During the test of the female seat: the tip type bullet head is inserted between the bullet openings in the BTB connector, which produces a certain amount of opening to the bullet of the BTB connector, and the contact surface of the bullet of the microneedle module always keeps in contact with both sides of the bullet of the BTB connector.
The head of high current shrapnel microneedle module has a self-cleaning design, without manual maintenance, which can ensure the long-term stability of the test and reduce the test cost. Its integrated shrapnel structure has the characteristics of low processing difficulty coefficient, short production cycle and fast delivery time, which greatly improves the BTB connector test efficiency. This high current spring clip micro pin module is designed to adapt to BTB connector. It has stable connection function and can perfectly cope with small pitch, high current and male and female seat tests.
