Success Story - Double - Sided Optoelectronics Wafer Test System

May 13, 2019
The customer wanted a manual double-sided probing (DSP) system to test silicon photonic chips and wafers using probe cards and manipulators. The top side of the device would be biased and the backside of the device had a light output that was captured by a detector. The detector was mounted on a manual X,Y, Z and theta stage. The devices tested had a variety of dimensions so a universal mechanically clamping chip carrier was designed to hold the devices. Carriers for different size wafers were also required
