SN74CB3T16212ZQLR - Materials Declaration

Hello,

My customer is looking the tin/silver/copper alloy content (in percentages) of the lead free solder balls used in the TI SN74CB3T16212ZQLR. They need to find out the percentages, which usually show up in a Materials Declaration Data Sheet for the package.  They are looking to find out if it is SAC405 (4% silver), SAC305 (3% silver), SAC105 (1% silver) or some other combination of alloys.

Thanks,
Alex
