Spring Pogo Pin Semiconductor Test Probe SCPC028 Applied to IC Inspection
Semiconductor test probes are usually called double-ended pogo pins. Common tip styles include B, J, J1, U, U1, etc. All of the probes are extremely thin and miniature, however, the requirement for their test accuracy is very strict. They are mainly applied to the fields of semiconductor tests and frequency tests of communication devices, for example, the frequency tests of mobile phones, walkie-talkies, computers, etc.
This product SCPC028 we will introduce is 0.28 mm in barrel diameter. It can be applied to the tests of products which requires relatively high accuracy, for example frequency tests of semiconductor and communication devices. Developed and manufactured on our own, this product takes the lead in the test industry. Our complete production lines can also meet the needs for mass production.
The barrel of this double-ended pogo pin is made from phosphor bronze plated with gold or gold clad phosphor bronze. The bottom plunger is made from beryllium copper plated with nickel and gold. The top plunger is made from SK4 plated with nickel and gold. The inner spring is made from music wire plated with gold and nickel. This probe pin could withstand the current up to 2 amps. The typical maximal contact resistance is about 150 milliohms.
The plunger can be pressed at a distance of up to 1.05 mm. But it is better to be pressed at a distance of 0.7 mm at most in working environments. Otherwise, the spring will probably be damaged severely under constant pressure. When the plunger is pressed at a distance of 0.7 mm, the loaded force is about 25 gf, which fluctuates to a tolerance.
