Abstract
Design of experiments have been done by using Minitab statistical software to improve the reliability and product quality of domestic ceramics packages, which are used for aluminum wedge bonding process. And intuitive analysis and variance analysis of the design of experiments results of CQFP84 domestic ceramic package, which are used for aluminum wedge bonding process have been done. Ultrasonic power, ultrasonic time, bonding force and ultrasonic power ramp time on the effect of the bonding pull and its significant level have been discussed. The study shows that the second parameter of bonding pressure and ultrasonic power, and the first parameter of ultrasonic power ramp time have significant influences on bonding pull. Better bonding process parameters are obtained as bonding pull for a reference index. Bonding pull is obviously enhanced through validation experiment, and its dispersion has been improved significantly.关键词
