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 three power land pads should be Solder

Mask Defined (SMD), with a minimum overlap of

the solder resist onto the copper of 0.05mm to

accommodate solder resist mis‐alignment.

 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 power pad lands.
