 J Micro Technology is a worldwide supplier of probe station and text fixtures for advanced semiconductor devices and packaging products. We supply the necessary accessories to bring the precision of coaxial/coplanar microwave probes to non-coplanar test structures through precision low cost thin film network (TFN) "adapters,” ProbePoints and affordable microprobing test fixtures and probe stations. We are breaking unprecedented barriers in performance and compatibility in the industry to provide faster, more accurate testing using the latest technology.

We have provided engineers and researchers in government agencies, universities and materials research industries with state-of-the-art equipment and innovative solutions since 1993. Our products produce measurable, consistent results with delicate, valuable materials and remove undesirable variation and uncertainty. Leverage affordable, top-quality engineering tools in your tests to reach successful developments and actionable information faster, even working with tight deadlines and budgets.

Equip your workspace with cutting-edge technology anywhere in the world with a single click. Browse our extensive selections of ProbePoint stations and accessories to find the right size, device and fitting for your function. Our stations are ideal research and teaching tools as well as key sources for production and development. We work closely with clients to ensure top performance and compatibility, as well as quick, reliable shipping, and we are happy to answer any questions you may have.
