San Francisco Circuits is pleased to publish the important factors that drive trace width, length, and style during the PCB design process.

August 5, 2020 - San Francisco Circuits (SFC) shares in a recently published article entitled, "The Importance of PCB Trace Widths in PCB Design," that there are a variety of applications that demand specific trace layout characteristics and how or when to incorporate them into PCB designs. A specific PCB application will determine trace widths and trace types in a PCB design and a balance should be maintained between PCB fabrication cost, board density/size, and performance.

The purpose of a PCB trace is to connect any kind of electrical signal - analog, digital, or power - from one junction to another. And if a PCB has specific design requirements such as speed optimization, noise or coupling mitigation, or high current/voltage, the trace widths and types might be more important than optimizing for manufacturing cost of the bare PCB or overall board size.

There are a number of trace-related specifications in PCB fabrication. The following trace-related specifications begin to drive up bare PCB fabrication costs. The costs become considerably higher due to tighter PCB tolerances and higher end equipment needed to both manufacture and inspect or test the PCBs:

• Trace widths narrower than 5 mils (0.005")
• Trace spacing closer than 5 mils
• Via holes with a diameter smaller than 8 mils
• Trace thickness thinner or thicker than 1 ounce (which equates to 1.4 mils)
• Differential pairs and controlled lengths or trace impedance
