Hello Michael, Interesting article I came across some time ago that may be of some use to you with respect to heatsinking. I think that it was referenced on the IPC TechNet.
www.geocities.com/Heartland/Hills/5131/thermal.htm Increased copper weight may help you as well. Be aware of your PCB's ambient conditions as well. Temperature rise of traces due to current will be additional. Make sure you keep well away from your board material's Tg. (I usually spec a minimum Tg of 140C.) Avoid going through the board using just the plating of a via wall. (make sure there is a lead in the hole) CTE of boards in the z-axis is worse than in x or y. regards, Phil. -----Original Message----- From: Michael Biggs [mailto:[EMAIL PROTECTED]] Sent: Thursday, 18 July 2002 05:48 To: 'Protel EDA Forum' Subject: [PEDA] 90 degree C? Hi all, Anyone run very hot traces @ like 90 degree C on there PWBs and or use surface mount heat sink around the component( like a D-PAK)? Thanks for any response. I know this is a Protel questions group but everyone seem knowledgeable in design layout.
