With such a low standoff [eg, 1-2 thou of solder], we doubt that you can clean under QFN, either. For more, search the fine SMTnet Archives to find threads like http://www.smtnet.com/forums/Index.cfm?CFApp=1&Message_ID=19247

This year, MIRTEC will launch several new inspection machines equipped new cutting-edge technologies. MIRTEC is proud to be promoting these new machines in booth #1J10 at NEPCON China 2017, one of the biggest technical exhibitions of SMT and EMA, from April 25-27 at the Shanghai World EXPO Exhibition & Convention Center. MIRTEC’s new machines have been developed under a concept, ‘Perfect Inspection Solution’. This is an inspection concept involving the combination of 3D, 2D, and side-camera inspection.

Voids are a plague to our electronics and must be eliminated! Over the last few years we have studied voiding in solder joints and published three technical papers on methods to "Fill the Void." This paper is part four of this series. The focus of this work is to mitigate voids for via in pad circuit board designs. Via holes in Quad Flat No-Lead (QFN) thermal pads create voiding issues. Gasses can come out of via holes and rise into the solder joint creating voids. Solder can also flow down into the via holes creating gaps in the solder joint. One method of preventing this is via plugging. Via holes can be plugged, capped, or left open. These via plugging options were compared and contrasted to each other with respect to voiding. Another method of minimizing voiding is through solder paste stencil design. Solder paste can be printed around the via holes with gas escape routes. This prevents gasses from via holes from being trapped in the solder joint. Several stencil designs were tested and voiding performance compared and contrasted. In many cases voiding will be reduced only if a combination of mitigation strategies are used. Recommendations for combinations of via hole plugging and stencil design are given. The aim of this paper is to help the reader to "Fill the Void."

1.Vias near SMD pads: Solder can flow into the via after melted. As a result cold joint will appear in the end. Check the picture below. 2.Vias on SMD pads: Solder can flow into the via more easier after melted. Check the picture below. 3.Via opening without soldermask covered. When workers solder TH parts by hand, soldering iron can touch vias sometime, then tiny amounts molten solder will stay on vias. This can lead to electrical short easily. We recommend you make all vias tenting (covered by solder mask) if it is possible.
