plasma cleaning

The results from encapsulation peel tests, die and encapsulant pull tests, bonding wire pull tests and C-Mode SAM ( C-SAM) examination are presented. This paper demonstrates that the optimized plasma cleaning process would enhance PBGA package qualification level and improve the process yields and productivity.

陈述了密封剥离试验、芯片和密封剂拉力试验、焊线拉力试验和C-模式SAM（C-SAM）检查的结果，证明了最佳的等离子清洗工艺会增强PBGA封装的定性等级，并提高工艺效率和生产率。
