2. Intersil Pb-free products employ special Pb-free material sets; molding compounds/die

attach materials and 100% matte tin plate termination finish, which is compatible with

both SnPb and Pb-free soldering operations. Intersil Pb-free products are MSL

classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free

requirements of IPC/JEDEC J Std-020B.
