Automated Test Equipment tests whether parts failed or passed a test. During the test process, large amounts of data are collected and saved for statistical analysis. By analyzing this data, production errors can be detected at an early stage and corrected accordingly.

With yieldPower it is possible to do statistical analysis on data, which is generated by automated test equipment.
yieldPower is a desktop based application which is ideal for use by engineers on the work floor or test engineers in a fabless environment.

Statistical Process Control

yieldPower uses methods which are part of Statistical Process Control (SPC). SPC allows users to analyze production information and apply those results for production control. The combination of reading and analyzing ATE tester data, combined with SPC analysis, makes yieldPower the ideal software tool for the ATE industry.

STDF and CSV Data Input
yieldPower uses STDF or CSV formatted input.

• The STDF data format, which was developed by Teradyne, is the de-facto standard widely used throughout the ATE industry.
• CSV is known as comma separated file format. It can be handled by most spreadsheet programs.
