Contact Quality & Prober Z Height Setup
AutoZ is a production setup software tool designed to remove the time‑consuming bottleneck of repeatedly verifying contact quality. Maintaining consistent Z‑height across different test environments and high‑density probe cards is difficult, often leading to poor contact or probe‑tip damage from overdrive. AutoZ minimizes setup time and protects probe tips by ensuring accurate and consistent Z‑height settings.
Customer Challenges
-
Manual Z‑height adjustment is slow, inconsistent, and error‑prone.
-
High‑density probe cards are difficult to manage manually.
-
Overdrive risk leads to costly probe‑tip damage.
-
There are no traceability for Z‑height settings.
Value to Customer
Efficient and Automated Z‑Height Optimization
-
AutoZ identifies the optimal Z‑height efficiently, replacing manual adjustments and significantly reducing setup time and engineering effort.
Stable and Repeatable Contact Quality
-
Standardized Z‑height across operators, shifts, devices, and environments ensures a consistent and reliable contact window.
Improved Test Performance and Yield Stability
-
Consistent probe‑to‑wafer contact reduces variation and failures, delivering more stable wafer‑sort performance.
Lower Maintenance Cost through Probe‑Tip Protection
-
Built‑in overdrive control prevents excessive force, protecting needle tips and extending probe card lifetime.
