Re: gEDA-user: thermal vias in pcb

So, anyway, should I specify some kind of pin with clearance smaller than the pad? How can I keep pcb's DRC from whining? I'm sure the answer is simple but I'm not sure how to approach it. TIA, dave One way I can think of is the way a connector with many redundant connections to the same

Re: gEDA-user: thermal vias in pcb

I use a number of parts with backside thermal pads. Draw the rectangle as you describe to comfortably surround the vias. Then with the mouse over the rectangle hit 's'. This will flood the thermal reliefs on the vias. If you want to ever de-solder the part from the back, make sure the pad on t

What is the easiest way to create "thermal vias"? Not a via with a thermal relief -- I can do that :) .. but a via with no thermal relief punched into polygons on both sides of the board that ends up getting filled with solder to help create a large thermal mass to be used as a heat sink. The
