Electronics Forum / CAD / August 2005Thermal Relief in Protel
Hi All, I want to have a pad on the board with no thermal relief, connected to a plane. How do I do this in Protel 99 SE? Is there an option somewhere? Thanks, Brendon Brendon, First you must be sure if it is a plane or a poured polygon, there are two different rules. Under DRC rules ("D", "R") go to the second tab ("Manufacturing") and find the appropriate connection rule for either Power Plane Connection Style or Polygon Connect style. Write a rule for your pad that you want directly connected and set the connection type to "Direct Connect". You could write the rule for your PAD using the Footprint/Pad specification or you could make a Pad class that contains that pad and write the rule using the pad class.

Select the net and change the thermal relief type to direct connect. I am not sure if this will affect the whole net or if you can select one via or pin and change the scope of the rule.
