 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.

 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.
