Hello Tom, Yes. In fact, I would recommend it. The thin sliver of solder mask that you may be able to achieve in between the pads of such devices tends to break away anyway and becomes a problem.

Is it ok to block open the solder mask on gull-wing i.c.'s with .4mm AND .5mm pitches? It seems to get enough web in between the pads to stick will cause a LPI registration thats too tight, with possible smearing. And if you make the pads themselves too narrow -- thats another problem.
