Expertise
The mechanical engineering of semiconductor test, at depth
Narrow specialty, deep expertise — across front-end probing and back-end final test.
Technical domains
Where we go deep
Test sockets & contactors
Custom contacting for demanding applications — fine-pitch, high-current, high-frequency, high-temperature — with contact-force engineering at both extremes: 0.1–0.5N per-pin protection for fragile CSPs, and uniform 700N+ self-locking clamping for burn-in strips. Five patents in this domain alone.
Burn-in & strip-test systems
Complete strip-test contacting systems — the founder created a strip-test product line at a leading socket manufacturer, including the self-locking lever-cam mechanism published as EP3023801.
See the mechanism in 3D →DIB & load board mechanical design
Device interface boards engineered for stiffness, planarity, serviceability, and integration — including the Versatile DIB system developed for Infineon.
Docking & interface systems
The mechanical connection between tester and prober/handler, where microns of repeatability decide yield. Includes a patented tester-handler connection system (DE102019007618).
Thermal & environmental interfaces
Tri-temp mechanical design and a patented localized sealed-chamber approach (DE102019004446) for fast, low-latency controlled-environment testing without full-size chambers.
Contact-force & planarity engineering
The root-cause discipline behind non-electrical yield loss: force distribution, planarity drift, differential expansion — the failures that look electrical until you trace them to the interface.
Custom fixtures & test cell integration
Adapters, carriers, alignment tooling, and the integration engineering that makes the whole cell work.

How we work
At the mechanical-physics level, not the symptom level
We solve at the mechanical-physics level, not the symptom level. Many "electrical" problems — false fails, measurement scatter, yield drift — are mechanical at root: a force gradient, a planarity shift, an expansion mismatch. We design for your platform, your supply chain, and your maintenance reality, then document until your team owns it completely.
