Absolutely agreed/understood/known. The intention here was to eliminate = the=20 need for a heatsink, or in the case of my breadboard, I do this to reduce= the=20 heat on each device to the point where I don't burn my fingers when I=20 occassionally touch it. Of course in other circumstances, a heatsink is=20 needed still, and then doing this is not as beneficial.
