Design Guidelines: Basic Conductors

Patterning - All circuit designs contain critical dimensions necessary for compliance and performance.  It is important to consider these when designing the circuit to not add unnecessary cost to the design.  Conductor tolerances of <0.001" require more costly tooling to ensure compliance.
