Unnecessarily tight constraints on a PCB can drive up costs, while an insufficient set of physical parameters can mean that that PCB may not meet the necessary requirements in the field. The goal is to find an acceptable balance between precision and price.

The article covers:

  • Geometric dimensioning and tolerancing, including for mounting holes
  • Designing with a balanced layer stack-up
  • Two methods to ensure even metal distribution
  • The use of stiffener bars for increased stability
  • The advantages of metal core PCBs

The techniques outlined in this article will help designers maintain compliance, keep the board flat and enhance surface mount component assembly. To find out more, read the full article on San Francisco Circuits’ website.
