Design and Performances of the Transducer Based on Chip-Type Silver-Palladium Alloy Film Bridge
摘要
Abstract
In order to realize the chip-based design of the transducer bridge of initiators and improve the processing accuracy and efficiency,a silver-palladium alloy film was used to prepare a chip-based initiator transducer bridge,and the performance research was conducted.The results indicate that the prepared chip-type silver-palladium alloy film transducer bridge can improve the accuracy of transducer resistance through laser trimming tuning technology.The resistance is 1 Ω,and the accuracy can reach±1%.The minimum firing parameters of the alloy film chip-based transducer were measured as 16 V(33 μF)and 2.9 A(50 ms),with a maximum non-fusing current of 1.3 A sustained for 5 minutes,reaching 215.13℃peak temperature.The safety current for the alloy film bridge-based transducer initiators is 1.3-1.6 A,meeting the safe-ty requirements of 1 A,1 W,and 5 min for insensitive initiatiors.It could successfully ignite lead styphnate(40 mg)and B/KNO3(180 mg)charge sequences with reliability.It provides technical references for the standardized design and appli-cation of high-efficiency and high-precision bridges in initiators.关键词
