Solder Resist
It is recommended that the lead lands are Non 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.
The land pad should be Solder Mask Defined (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.
