In the development of high-end production of board-to-board connectors, what measurement standards are used by manufacturers?

The advantages of board-to-board connector patch terminals are flexible and convenient, fast transmission speed, wide range of applications, practicality, and popular in the end market. Board-to-board connectors are mainly used in digital products, drones, car recorders, video cameras, etc. Board-to-board connectors tend to be more and more sophisticated and high-performance development, so the direction of development of board-to-board connectors has also turned to small-pitch, low-height and multi-polarization. Board-to-board connector flexibility and transmission performance as well as miniaturization, thin features can be well adapted to the development of intelligent equipment changes, to maintain a strong connection, but also to minimize the product and equipment to take up space.

For board-to-board connector testing, Lianxin Technology has a board-to-board high-current shrapnel micropin module that meets the above test requirements. As a transmission medium with strong conduction function, the high-current shrapnel micropin module has already taken the advantage from the shape structure, with one-piece shrapnel structure, gold-plated and hardened processing, enhanced conductivity, no current attenuation in the transmission process, electrical stability, and good connection function. Board-to-board connectors are male and female seat pairs, plugging force is an important mechanical properties, in the test for the male and female seat connection and current transfer is also required to maintain stability. Another advantage of the shrapnel micro-pin module is that it can be used with different head types to cope with the board-to-board connector male and female seat test, specifically as follows: with serrated shrapnel contact board-to-board connector male seat, and the top of the male seat shrapnel multi-point contact, to maintain the stability of the contact; with a pointed type of shrapnel and the board to board connector female seat to maintain contact on both sides, so that the connection to maintain long-term stability. Board-to-board connector test considerations 1, pay attention to the pin and spacing board-to-board connector pin number, pin spacing is the basic basis for connector selection, choose how many pins of the connector according to the number of signals connected to the number of pins should not be too much for some chip connector pin number. Because in the SMD welding process due to the role of high temperature connector plastic will be deformed by heat, the middle of the bulge caused by the pin soldering. 2, pay attention to the electrical properties of the connector's electrical properties mainly include: limit current, contact resistance, insulation resistance and resistance to electric strength, etc. When connecting high-power power supply, you need to pay attention to the connector. Connection of high-power power supply need to pay attention to the limit current of the connector; transmission of high-frequency signals such as LVDS and other signals need to pay attention to the contact resistance. Connector usually has a low and constant contact resistance, generally tens of mΩ to hundreds of mΩ ranging from 3, pay attention to the environmental performance according to the specific application environment. If the application environment is more humid for the connector's moisture resistance, salt spray resistance requirements are high, to ensure that the connector's metal contacts are not corroded. In the field of industrial control on the connector vibration shock performance requirements are high, so as not to connectors in the vibration process to fall off. 4, pay attention to the mechanical properties of the connector mechanical properties, including unplugging and mechanical anti-dumbness, etc., mechanical anti-dumbness of the connector is very important, once inserted in reverse is likely to cause irreversible damage to the circuitry.
