We swapped our previous probes for the PT062B80-2300A across six ICT fixtures running 800+ boards per shift. False failure rates dropped by roughly 35% in the first month. The probes held stable contact resistance past 120,000 cycles before we saw any drift. We used to rebuild fixtures every 10 weeks. Now we’re pushing past 16 weeks on the same probe set.

Our EV power module validation fixtures need probes that carry 2+ amps and survive thermal cycling from −40°C to 80°C. The PT068B60-1605E handled both without contact resistance exceeding 40 mΩ across the full temperature sweep. We ran 15,000 cycles under those conditions, and the probes stayed within spec. That consistency made a real difference during PPAP qualification.

Single-ended FAQs

What is the smallest plunger diameter available for single-end probes?

We manufacture single-end probes with plunger diameters as small as Ø0.15 mm at a ±0.01 mm tolerance. At this scale, the probe fits test point pitches down to 0.50 mm for fine-pitch BGA and QFN package testing. The PB031B570B-35A delivers 35 gf spring force at this diameter. That is enough for oxide penetration while helping protect the bond pad.

How long do single-end probes last in a production fixture?

Cycle life ranges from 20,000 to 200,000+ insertions depending on plunger diameter, plating thickness, and spring force. Match the rated durability to your fixture’s expected lifetime test count. A line running 500 boards per day needs probes rated at 100,000 cycles minimum.
