Semiconductor Test Probe Pogo Pin SCFE035 for Integrated Circuit 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 SCFE035 we will introduce is 0.35 mm in barrel diameter and 18 mm in total length. 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 The bottom plunger is made from SK4 plated with nickel and gold. The same is with the top plunger. The inner spring is made from music wire plated with gold and nickel. This probe pin could withstand the current up to 1.5 amps. The typical maximal contact resistance is about 150 milliohms. The plunger can be pressed at a distance of up to 1.5 mm. But it is better to be pressed at a distance of 1 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 1 mm, the loaded force is about 38 gf, which fluctuates to a tolerance. For details, please check parameters in below table. Materials (plated) Barrel: Ph, Au on Ni Plated Bottom Plunger: SK4, Au on Ni Plated Top Plunger: SK4, Au on Ni Plated Spring: SWP-A/B, Au on Ni Plated Electronic Specification: Current Rating: 1.5 amps Contact Resistance: 150 milliohms max Bandwidth: 9.3 GHz at -1dB Inductive Reactance: 1MHZ at -0.05517 uH Capacitive Reactance: 1MHZ at 0.462432 uF Specifications: Full Stroke: 1.5 mm Rated Stroke: 1 mm Spring Force: 38±11 gf at load 1 mm Mechanical Life: about 200000 cycles For more information, please check below catalog.
