Advanced probe and measurement systems targeting Micro Display applications


VEGA Series

High performance Laser Diode probe & test solutions


GEMINI Series Overview

Micro LED (µLED) is a disruptive optical technology breakthrough in the display industry. Micro LED displays offer tremendous potential for consumer/ display/ automotive applications because they are brighter, faster, and longer life compared with other emissive devices.

With years of experience and customer interactions gained in Optoelectronic devices testing, MPI introduces the GEMINI series wafer probers to provide fast, efficient, and precise measurement to help you tackle the Micro LED test and measurement challenges.

GEMINI Prober Series Key Features

Excellent alignment accuracy thanks to the combination of accurate probing tables, fully integrated control software and a finely tuned motorized positioning system.
Highly precise probing capability for Micro LEDs with very small pad sizes and pitches down to the micron scale.
- Sophisticated needle force control
- Accurate thermal control
- Anti-vibration solutions for different test environments
- Probe contact compensation

Integration of probe cards or micro-positioners for reliable Micro LED backplane measurements.
- Ability to test optical devices with complex pad layouts with ease
- Flexible probe sequence management

MPI SIRIUS prober control software provides comprehensive control functions from basic wafer alignment, mapping, probe mark inspection to the deployment of MPI’s advanced Needle Alignment Mechanism (NAM) technology.

The STARGAZER Photonics Test System features a user-centric design that can be flexibly configured and programmed according to your unique test requirements.

Flexibility: With support for multiple test recipes, the user can flexibly select or modify the workflow or edit parameters according to the product and tests being performed.
Production Management: Manage lab/production data via the intuitive and easy-to-use software interface. Integrated real-time system monitoring and reporting enable a smooth and fully unattended test process.
