Hello,

Thank you for posting in Infineon community.

All metal surfaces are tin plated, except area of cut. Refer the below link for documentation

Thanks & regards,

Anil

thanks - that spec says it is a Tin finish, but do you know if that is considered a matte finish or a shiny finish?  The concern is tin-whisker growth, which is less with the matte finish than the shiny finish.
