Recommended maximum paste thickness is 0.25mm
Devices can be cleaned using standard industry methods
and solvents.
Note 1:All temperature refer to topside of the package,
measured on the package body surface.
Note 2: If reflow temperatures exceed the recommended
profile, devices may not meet the performance
requirements.
