Slot Verifier Board

Problem

Customer requested a method of automating the test and verification of driver boards in their burn-in system. Currently this is a manual process, requiring each PSU and CLK signal to be measured and recorded manually. In a fully loaded system this could be over 2000 measurements

Solution

Abrel developed the Slot Verifier Board, which automatically measures and records the system driver board parameters

Overview

Capture

  • Provides performance checks of each slot in any Burn-in Oven
  • Checks the functionality and provides a load to each PSU
  • Programmable limits for all Pass / Fail data
  • Verifies and measures all clocks coming from the driver board
  • Functional check for modules such as SPI / I²C and other custom modules
  • Plug and play Base Board for most common BIB styles
  • Front End Software control and data logging capability
  • Slot setups can be defined and easily reloaded
  • Multiple oven setups can be defined and reloaded at any time
  • Modular Card capability that suits specific Driver boards
  • Extremely fast and accurate method of verifying oven functionality and performance
