Starlino has a neat technique for making a cheap breakout board for lead-less QFN chips. In brief:Drill a hole in a proto board so that the chip barely fits inside and has its connections on the same plane as the board. Fill gaps with epoxy or putty.Tape over everything except one pad and and small path to the proto board.Use a conductive ink pen to lay a path. Remove tape before the ink dries to keep from breaking the pathway when it hardens. Wait for it to dry and repeat on the other pads.The best part is that no hot air or breakout board is required.
