Minimum Component Spacing with Minimum Solder Mask Width of 4mils | 16 May, 2014

Desire to push the spacing limit as usual. If I place two 0402 components spaced 7mils between the edge of the two components adjacent pads, which allows for 4mils solder mask webbing between component pads, what would the risk be? Potential for solder shorting, potential for insufficient solder on of the two pads, and/or both?

Consider this combination: * IPC-7351B - Generic Requirements for Surface Mount Design and Land Pattern Standard * IPC Tools & Calculators [ipc.org/contentpage.aspx?pageid=PCB-Tools-and-Calculators ] * Component fabricator suggestions
