Embodiment Construction
[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0016] Such as figure 1 Shown: An automatic test system for probe life, such as figure 1 As shown, the high-frequency response force sensor 1 is placed on the platform, and the single probe or multiple probes 2 to be tested are loaded into the probe holder 3. According to the size of the probe 2, its diameter is generally 50-300 Micron, the probe holder 3 that fixes the probe 2 can fix one or more probes 2 in a probe holder 3 at the same time to meet the simultaneous measurement requirements of a single probe and multiple probes. The circuit board 10 on the fixture 3 leads the electrode of the probe 2 out, and then connects with the four-wire tester 8 through the probe electrode lead-out line 4 connected to the circuit board 10, and collects the contact of the probe 2 through the four-wire tester 8. The change of resistance, the pro...
