Narrow pitch

Narrow pitch

Tip shape of 4terminal sensing test fixture which uses 20μm probe.Minimum pitch between probes is 40μm.

Semiconductor and PCB are getting smaller by manufacturing technology progress. With these progress, narrow pitch of probes are also required for the probe card.This trend is expected to advance, especially in the field of logic IC.
We set a narrow pitch probe, and we achieved 40μm matrix as an actual minimum result. We can set a large numbers of probes in fixture, so that apply to from multi DUT test to wafer test.
