HAPS Probe Station

4~12 inch set ups. Modular design, highly cost-effective and can be upgraded as your requirements changes.

In order to acquire accurate and reliable test results in the cutting edge tests, one of the key factors is to use a probe station system with ultra mechanical accuracy and stability.

HAPS is built on a granite base with less than 5 micron planarity. This design not only assures the high planarity in X-Y motion but also provides a rigid and stable platform for high accuracy tests. To achieve positioning accuracy, we use precise micrometer heads to drive spring loaded X-Y axes. With an air bearing X-Y stage, user will be able to move the X-Y in coarse positioning smoothly and quickly, thus greatly reducing set up time and improving test efficiency. One of the most common applications of HAPS is millimeter wave device characterization. The accuracy and stability act as an important role in protection of fragile and expensive mmW probes while producing reliable test results.

TWO Set Ups for HAPS

HAPS with a Slim scope is generally set up for High-performance RF, multi-contact/mixed signal probing, Single-ended broadband/mm Wave, THz, source/load pull, RF noise probing. All these measurements require the system to be ultra-accurate and stable for ensure reliable measurement output. Slim Scope and Super scope are interchangeable.

HAPS with a Super scope is generally set up for probing on tiny geometric structures of wafer level reliability
tests, failure analysis, high power tests, etc. HAPS’ intuitive manipulation enables users focus more on their measurements rather than manipulation. Slim scope and Super scope are interchangeable.
