Hello,

PN TLC7705QD bondwire changed from Au to Cu per PCN # 20120808000 issued from CY 2012. The part mass changed because of this bondwire change ? If it did, please provide the mass of device with gold bond wire and with copper bondwire.

Thanks,

Hi! The part mass change from Au to Cu wire is not significant or negligible. The mass of the leadframe & mold compound are the significant ones compared to the wire.

ok, thanks for the information! Please, confirm that TLC7705QD device has a mass with copper bondwire of 0.09675304 g. Also, can you please provide the mass of the device with gold bondwires. The change is negligible, but currently an analysis is needed of both devices and the mass needs to be compared.
