Descipriton of the water testing of ASICS at Glasgow

Introduction

The following is a decripton of the setup used to test wafers of ABCn ASICS at Glasgow.

The setup uses a Cascade semi automaitc propbe station, with a cutosm built probe card. The probe card is connected to a PCB driver card, which sends signals and data to and from the PC. 2 NI cards are used for signalling, voltage sourced for power, multimeters for measuring the DACs and an adapted verstion of SCTDAQ is used for control software

Hardware

Driver Card

Connections

• 2 64 pin twist & flat cables
  • Connects the Driver card to the probe card
  • Supplies the LVDS, CMOS signals, control lines etc
• DB9 -> 4 Banana leads
  • 2.5V provides ABCn power
  • ~4.5V for driver board (locally regulated). Taken to 3.3V, 2.5V & 2.0V by local regulators
• Lemo 2 pin
  • Analogue output
  • Multiplexer out from ABCn to multimeter
  • Bandgap reference for Vreg on ABCn
• 2 Large multi pin connectors
  • connected to NI cards in PC
• PL7
