Design

 

 

 

 

 

Hardware Design & Fabrication

  • Selection of appropriate Tester platform capable of handling the product for the agreed Test Plan Matrix
  • Design of the product hardware load board schematic and the Adaptor Board for interfacing with the DUT.
  • Selection of Manual Test Socket, Handler Contractor Mechanism inclusive of the Mechanical interface design
  • Design of the probe card based on the die pad layout and suitable interface with the Tester Load Board.
  • Fabrication of designed hardware modules like Load Board, Manual DUT Board, Handler Interface Board & the Probe Cards

 

Program Development & Debugging

  • Development of the test program code for the designed hardware schematic as per the agreed Test Plan Matrix conditions.
  • Debugging of the program using the constructed hardware modules and known good products
  • Verification of test measurement data for each parameter
  • Refinement of hardware or test program depending upon the product characteristics & the observed values, for better performance
  • Test Time Optimization is considered as part of the program debugging

 

Product Characterization & Correlation

  • Verification & Refinement of the developed application program and set-up using Correlation Units provided by the Customer, wherever available.
  • Correlation of Tester measurements with Bench parameter values in case of non-availability of known correlation units
  • Electrical Characterization of New products for various parameters & input conditions.
  • Statistical Analysis of the measured values & Determination of test limits
  • Generation of Schmoo & Statistical distribution plots wherever possible for review by the Design team
