4. Let's say you want to apply it to the Net Class named POWER(6) - Click the dropdown in the Referenced Spacing CSet column, then select your preferred spacing constraint set. In this case, we go with DEFAULT (see below). Reason: Clearance and creepage are crucial for electrical safety, especially in high-voltage designs and harsh environments. Creepage travels along the surface of the PCB while clearance involves the space between in the air above the PCB. WARNING: As stated above, specific clearances and creepages are not addressed in OrCAD X. However, some kind of spacing needs to be established. Impact: Enhances product safety, reliability, and compliance with safety standards. Component Spacing: Minimum Distances Between Components to Avoid Interference and Facilitate Cooling Purpose: Ensures adequate spacing between components for assembly processes and thermal dissipation. Image: Diagram showing minimum spacing requirements between different component types on a PCB. Please follow IPC 2221 for spacing requirements, i.e. Edge-to-Edge (EE), Side to Edge (SE), Edge to Side (ES) and Side to Side (SS). Reason: Proper component spacing is crucial for manufacturing processes and thermal management of the PCB, especially during automatic soldering processes, manual soldering, and PCB Assembly. We will address both the 2D and 3D aspects of component spacing. 15 www.cadence.com OrCAD X Constraint Management Guide
