----- Original Message ----- From: "Trevor Page" To: Subject: Re: [EE] TO-220 heatsinking: THANKS! Only just catching up with email before going to bed. In all my designs where a heatsink is not needed (in theory) I place a copper pour as big as possible on the top and the bottom of the board, and leave enough room for a TV4 heatsink they only cost ~au$0.50 in qty's of 1000 and do for all the jobs I have needed where a heatsink is more a precaution than a requisite.
