Why does the pogo pin get stuck?ground electrode manufacturer

　　Pogo pin, also known as PogoPin, pogo pin, thimble, charging pin, etc., has the characteristics of high life, high current, low impedance, corrosion resistance, etc. It is widely used in semiconductor equipment for connection.

　　In use, some customers will encounter problems such as the pogo pin compression is not smooth, the card pin is seriously bad, the preload is not smooth, and the needle cannot work normally.

　　Reason one:

　　Appearance status summary:

　　1. Sample 1 has obvious residual glue in the nozzle under the microscope, and the glue has been solidified and hard.

　　2. Sample 2 has obvious residual glue in the nozzle under the microscope, the glue is not completely solidified, and the needle shaft can move slightly.

　　Reason two:

　　Analysis: During the process of disassembling the needle shaft, the solid glue fell off, and the needle shaft was pressed and bounced back to normal.

　　Reason three:

　　Analysis: 1. After disassembling the defective sample 2, it was found that there was colloid on the needle shaft

　　2. Observe the spring and needle, no abnormality.

　　Summary: 1. The reason for the shrinkage of the needle and the stuck pin of the bad sample 1 is that there is a solid glue plugging the nozzle, resulting in

　　The needle shaft cannot be pressed properly.

　　2. The reason why the bad sample 2 is stuck is that the nozzle is blocked by the colloid, resulting in the stuck pin.

　　3. There is no process environment with glue in our production riveting process.
