PCB traces serve as conduits for signals—be it analog,digital,or power—linking different points on the circuit board. In scenarios where design specifications demand enhanced speed, reduced noise, or the management of high current or voltage, selecting the appropriate trace widths and types can take precedence over minimizing the manufacturing costs of the bare PCB or the overall dimensions of the board.
This article explores:
- The definition of trace width and its meaning in PCB design
- Specific trace requirements that may increase PCB manufacturing and testing expenses
- Illustrations of various trace widths and thicknesses
- The methodology for calculating PCB trace width
- The approach to determining PCB trace resistance
- Considerations for trace spacing and length
- The role of ground-filled traces and planes
- Optimal practices for routing PCBs
