[ABSTRACT]Inordertorealize thechip-based design of thetransducer bridge of initiators and improve the processing accuracyand eficiency，asilver-palldiumaloyfimwasusedtoprepareachip-based initiatortransducerbridge，and the performanceresearch was conducted.Theresults indicate thatthe prepared chip-type silver-paladiumaloyfilmtransducer bridgecan improve theaccuracyof 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）and2.9A（50 ms），with a maximum non-fusing curent of1.3 A sustained for5 minutes，reaching 215.13 （20号 C peak temperature.Thesafetycurrent forthealoyfilmbridge-based transducerinitiators is1.3-1.6A，meetingthe safetyrequirementsof1A，1W，and5min forinsensitive initiatiors.Itcould successullyignite lead styphnate（40mg）and B/KNO 3 （180 mg）charge sequences with reliability. It provides technical references for the standardized design and application of high-efficiency and high-precision bridges in initiators.
