Abstract: In this paper, the SMT attachment nozzle travel profiles are optimized for SAW filters, and some of SMT nozzles are comprehensively evaluated. The experiment results show that the SAW filter die drop & crack issue can be significantly solved during Backend assembly, by proper SMT nozzle selection and die placement process optimization.

Key words: SAWfilter, SMT, dieattachnozzle, dieattachparametersetting
