Is there any thumb rule for it or any calculator. I know about calculators which calculate the trace width depending on the layer stack up for different layers and different configurations. But, how do we estimate the trace width for a given net based on its current carrying capacity? That is how to determine the trace width given its current carrying capacity? Thanks for all your responses in advance. _____ Do you Yahoo!? ---------------------------------------------------------------------------- ----- DesignerCouncil Mail List provided as a free service by IPC using LISTSERV 1.8d To unsubscribe, send a message to [log in to unmask] with following text in the BODY (NOT the subject field): SIGNOFF DesignerCouncil.
