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
- 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
CLK Measurements
- Frequency measurement
- Rise time
- Fall time
- Positive Edge Peak
- Negative Edge Peak
PSU Measurements
- Programmable No Load Limits for Vmax and Vmin
- Programmable Load Limits Vmax, Vmin, Imax, Imin
- Verification of up to 6 PSU per BIB
- Current step back in increments of 0.5A until Vmin limit is reached
Front End Software
- Base Boards
- Base boards are available for most BIB styles
- Base boards accept standard Slot Verifier board
- Allows testing of drivers from multiple system types
