4. Once you're happy with your constraints, go to the 3D Clearance > Design section and apply the appropriate constraint to the relevant objects (e.g. Component to Component, Component to Board, etc.) Impact: Components, cables and connectors can cause an otherwise functional PCB to not be viable for product use because of lack of ability to fit into a larger system. You may also have components that, due to their spacing, make it difficult or impossible to place them on the PCB without going in a certain order. Poorly 3D constrained boards are also at risk of components and your design enclosures colliding. Rigid Flex PCB Constraints Teardrops (Fillets) Please see the Teardrops (Fillets) section in the Manufacturing Section. Component to Flex PCB Purpose: Components need to maintain a certain distance from the flexible parts of a PCB. The Constraint manager gives you granular control over components to rigid-flex placement and positioning. To explore that: 1. Open the constraint manager. 2. Go to the worksheet found in 3D > 3D Clearance > Constraint Set > Component to Rigid-Flex. 3. In this worksheet, you can choose Add Row at the bottom of the window to open the Create Component to Rigid-Flex Clearances window. 43 www.cadence.com OrCAD X Constraint Management Guide
