COMPANY

We build the test equipment, and we keep installed probers working

Probe-card test systems, equipment for the MEMS probe-card line, and the data layer and retrofits installed probers need. We build the test equipment ourselves.

Three things we do

The test equipment is designed and built here

We build the testers

What a probe card gets measured on, and how far the measurement goes, is decided by a machine we make.

We equip the card line

Equipment for a fourteen-station MEMS card line, incoming material through to shipment.

We bring old probers back

A prober whose mechanics are still good needs a data path, not a replacement.

How far it reaches

Channels are one scale; card pins are another

Tester channels: 16,384 is the standard configuration and 65,536 the maximum. A channel is a tester-side signal and is not a pin on the card - pin count is set by the device, and that scale lives on the product pages.

What a customer said

In the words of someone running a PCT5801

The PCT5801 probe card test system has exceeded our expectations in every aspect, from measurement accuracy to system stability and operational efficiency. Its advanced hardware platform, combined with intelligent software architecture, delivers consistent, high-precision results across complex test conditions. We are particularly impressed by the team's deep expertise and responsiveness; their ability to translate engineering challenges into reliable, production-ready solutions makes them a truly valuable partner in the semiconductor equipment space.
