Thus, in the "Pads Mask Clearance" dialog I usually set the Solder mask min width to 4 mil and the Solder mask clearance to 2 mil (assuming the 3 mil max is an infrequent worst case). • Non solder mask defined (NSMD) • Solder mask defined (SMD) As their title indicates, NSMD contact pads have the solder mask pulled away from the solderable metallization, while the SMD pads have the solder mask over the edge of the metallization, as shown in Figure 4. You should check with your PCB manufacturer what expansion value you should use and what is the minimum solder mask sliver allowed. They are two- component, alkaline developable LPI solder mask products for flood screen and spray application methods. 508 mm solder-mask diameter. Minimum Character Height (Legend)-. solder paste, reflow profile, component placement, component clearance (standoff), solder mask definition, pad height, solder paste print thickness in mils, cleaning agent and cleaning equipment are important factors. I have defined the testpoints to have a 65 pad on the solder mask layer. The pads are exposed to allow you to solder parts to them. If the solder mask completely covers most or all of the pad, the SMT part will be completely disconnected from that pad. I’d want 5/5/5 mil trace/clearance/rings and 10 mil drills to be happy. solder mask is slightly larger than the copper pad, providing a small clearance between the edge of the solder mask and the pad. Nevertheless, should be ok for a prototype (solder blobs to the rescue!). Solder balling results when small spherical particles with various diameters are formed away from the main solder pool during reflow, and do not coalesce with the solder pool. Usually, the size of the opening in the solder mask layer is bigger than the size of the pads of the part being used.
