Package Warpage Qualification Criteria

Problem Statement

  • Current standard is not adequate to predict good yield results at 1st and 2nd level assembly
  • Measurement methods (dimensional and test) not common


  • Define the qualification method and criteria; e.g., sample size, precondition, variations of material and processes (1st and 2nd level)
  • Establish measurement methods

Expected Output

  • Procedure and criteria reference for OEM and suppliers

Statement of Work

  • Statement of Work - Package Qualification Criteria to Ensure Acceptable Warpage Performance for 2nd Level Assembly (Version 3.0; September 21, 2010)
  • Note that this project is the first phase of what later became known as the Warpage Characteristics of Organic Packages projects (see links below)
