Traces - Thermal and Impedance Calculations   Message List  
Reply | Forward Message #587 of 601 |
To what point (or end) should I be concerned with thermal dissipation and
impedance values in the traces on my board? How do I calculate these values?

- The two boards I am designing are 2" x 4" and 2" x 6" in size.
- I am using some RS-232 and USB stuff mostly.

... The thermal issues depend entirely on your design. But if you aren't doing anything weird, RS-232 and USB shouldn't require any thermal consideration. ...

Greg, Overall power dissipation depends mainly on component size, placement and air flow. A few large parts, spread out over the board, can obviously dissipate...
