How Do I Calculate the Trace Width for my PCB? Primary Software: Electronics Workbench>>UltiboardPrimary Software Version: 10.0 Primary Software Fixed Version: Secondary Software:
Problem: I am having trouble determining the trace widths to use in my PCB layout in Ultiboard. Where can I find some help on this? Solution: As a general rule of thumb, the minimum trace width you can use will be determined by the maximum current that will flow in that trace and the copper thickness or weight of the trace. PCB handbooks typically provide useful formulas and tables for you to reference. However you can also find in the internet many Trace Width Calculators you could use as well. Open your favorite internet search engine and type trace width calculator, this should return mutiple choices. However, you must note that some trace lines may require more advanced calculations such as transmission lines and differential lines in which trace length, impedance, copper characteristics, and so on, may be critical to enter into the equation. A PCB Handbook is the best reference you can get or the IPC-2221 standard spec. In other cases, you may want to calculate how specific settings of a trace may affect the electrical characteristics. In Ultiboard you may want to use the:
You can locate these calculators inside the Tools menu. These calculators will provide the results in the Results tab of the Spreadsheet View. In their dialogs, click Help to learn more about their functionality. Related Links: IPC Website Attachments:
