　　How to check the board to the pogopin connector and the production process

　　The mechanical life of the board-to-pogopin connector refers to the life of the number of insertions, and the industry standard generally specifies 500 to 1000 times. When the specified mechanical life is reached, the contact resistance, insulation resistance and withstand voltage of the metal shell and the plastic shell should not exceed the value specified in the standard. So next, I will introduce how to check the pogopin connector of the board and the production process.

　　1. The voltage applied by the observation board to the pogopin connector shall not exceed 50% of its rated voltage.

　　2. The installation size of the board-to-pogopin connector is for inserting headers and soldering to the PCB. The length of the solder feet above requires that the exposed part of the PCB is greater than 0.5mm.

　　3. Board-to-pogopin connector with dense precision. When the PCB space allows, try to choose the model with positioning pins, which is convenient to operate when manual soldering is required.

　　4. Check if there is a foolproof design.

　　5. Check whether the material used in the pogopin connector contains lead.

　　6. The contact pressure of small board to pogopin connector is small. When using low current and voltage, it is recommended to use gold-plated or silver-plated connectors to avoid affecting the film resistance.

　　7. Observe the mating height of the board and the pogopin connector, and pay attention to whether it meets the soldering height of the components around the PCB. The mating height must be greater than the soldering height of the components around the PCB to ensure that there is a certain amount of room to ensure that there is no interference. Special attention should be paid to the height error of the components after the PCB soldering.
