Solder Resist
• The solder resist should be pulled away from the metal lead lands by a minimum of 0.06mm. The
• 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
• The land pad should be Solder Mask Defined (SMD), with a minimum overlap of the solder resist onto
• Ensure that the solder resist in-between the lead lands and the pad land is ≥ 0.15mm due to the high
• The four vias in the land pad should be tented or plugged from bottom board side with solder resist.
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.
