Solder Resist

The solder resist should be pulled away from the metal lead lands by a minimum of 0.06mm. The
solder resist mis-alignment is a maximum of 0.05mm and it is recommended that the lead lands are
all Non Solder Mask Defined (NSMD). Therefore pulling the S/R 0.06mm will always ensure NSMD
pads.
The minimum solder resist width is 0.13mm. At the inside corner of the solder resist where the lead
land groups meet, it is recommended to provide a fillet so a solder resist width of ≥ 0.17mm
remains.
The land pad should be Non Solder Mask Defined (NSMD), with a minimum pullback of the solder
resist off the copper of 0.06mm 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 pad land.
Each via in the land pad should be tented or plugged from bottom boardside with solder resist.
