# Success Story - Optoelectronic Wafer Prober - LEDS

May 20, 2019

By [Denis Place](https://blog.semiprobe.com/author/denis-place)

**Customer Requirements:**

Using a semiautomatic 150 mm probe system the customer wanted to test light emitting diodes (LEDS) in wafer form, on 150 mm and 200 mm metal frames and plastic rings. The wafers needed to be tested from ambient to 200 C using a thermal chuck. The LED device would be tested using probe cards and stimulated from the top and bottom. The light output would be captured by an integrating sphere (cube) mounted on multi-axis pneumatically controlled stages that allowed the integrating sphere to moved in and out of position and up and out of the way for changeovers. Customized fixturing to address all of the requirements were required.
