Electronic Test Probe Double-sided Spring Pogo Pin SCPA057 for 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. SCPA057 series is a medium-sized one in all semiconductor test probes. Both plungers are movable. 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. Its parameters are as below. Materials (plated) Barrel: Ph, Au on Ni Plated Bottom Plunger: BeCu, Au on Ni Plated Top Plunger: BeCu, Au on Ni Plated Spring: SWP-A/B, Au on Ni Plated Electronic Specification: Current Rating: 3 Amps Contact Resistance: 100 milliohms, max Bandwidth: 5 GHz at -1dB Propagation Delay: 24 ps Inductance: 1MHZ at -0.03664 uH Captance: 1MHZ at -0.704638 uF Specifications: Full Stroke: 0.63 mm Rated Stroke: 0.5 mm Spring Force: 45 ±13 gf at load 0.5 mm Mechanical Life: about 200000 cycles Company Information: Centalic Technology Development Ltd. was founded in 1980.
