Copper Wire for Wire-Bonded BGA and Leadframe QFP Packages Overview This qualification report summarizes the results of the reliability stress tests that were performed to qualify the copper wire used by wire-bonded BGA and leadframe QFP packages. Qualification Objectives Package Qualification Plan The objective of the reliability stress testing summarized in this document is to qualify the use of copper wire in wire-bonded BGA and leadframe QFP packages assembled by Xilinx-approved assembly suppliers in Taiwan and Korea. Specific reliability stress tests for qualification were run on selected qualification vehicles based on package type, package size, pin count, assembly site, and other known reliability risk factors. Reliability and Results Table 1 summarizes the results and test conditions for the reliability stress tests performed on the qualification vehicles. Based on the data gathered, copper wire demonstrates performance meeting the qualification requirements for use in wire-bonded BGA packages and leadframe QFP packages and is released for production use.
