Re: Part 2: Using PCB Layout Software: Schematic Capture & Component Libraries

NO RATINGS
To the question about using CFD to do thermal model. I've done some and have used consultants who specialize in it.  Here's my take on the subject. If it's a straight forward application, just measure the temperatures with a thermocouple and extrapolate. If it's complex geometry you might want to model it. But what you get out of it depends on what you put in. You still have to prototype it and get some anchor points and verification for your thermal model. Sometimes the answers are about what you expect. Sometimes experience helps you know what to expect. There are some rules of thumbs for power supplies: efficiency, power/square inch, should guide you on whether and how big a heat sink you need. I believe Ron goes over these in his book Practical Design of Power Supplies.
