It is recommended that the lead lands are Non
The land pad should be Solder Mask Defined
Solder Mask Defined (NSMD). The solder resist
should be pulled away from the metal lead lands
by a minimum of 0.025mm to ensure NSMD
pads.
(SMD), with a minimum overlap of the solder
resist onto the copper of 0.05mm to
accommodate solder resist misalignment.

6A Highly Integrated SupIRBuck
Ensure that the solder resist in between the lead
lands and the pad land is ≥ 0.15mm due to the
high aspect ratio of the solder resist strip
separating the lead lands from the pad land.
