electronics made easy
This is the old fritzing discussion forum. Search it for valuable information from 2009 to 2015.
I designed a very tight board. I used a custom SMD footprint that had extended lands so that I could hand solder them. I overlapped a via with an extended land. When exported to Gerber, the paste mask (for screening solder paste) covered the SMD land that overlapped the via. In other words, it seems that if a via overlaps the rectangle for an SMD land, Fritzing doesn't unmask the land for solder paste.
Not a big issue, just something to keep in mind and check. You probably should not put vias in SMD lands anyway.
