November 01, 2018

Success Story – Vacuum Prober – China

Customer Requirements:

• Semiautomatic vacuum probing system for testing MEMS wafers – Gyroscopes, Microbolometers
• Had to be able to mount blackbodies and a Polytec MSA-500 Vibrometer and interface with a Keithley 4200 parametric analyzer
• The system had to handle 100 mm, 150 mm and 200 mm wafers and operate automatically in a vacuum environment to 15x10-4 Torr
• Programmable manipulators with DC and High Frequency probe tips and probe cards with up to 24 connections
