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.
