system-level synchronization to ensure that mechanical fit and electrical connectivity are maintained across all interfaces. Cadence Design Systems +1 Key Components Child Boards: The individual PCBs (e.g., Motherboard, Daughterboard, Wi-Fi module). Interconnects: Board-to-board connectors, headers, or ribbon cables. System Enclosure: The mechanical housing that defines the physical constraints for all internal boards. Cadence Design Systems +1 2. Design Workflow and Best Practices Designing for multi-board systems involves several critical phases beyond standard layout: A. Logical System Connection Before physical layout, designers must define the logical "wiring" between boards. Net Management: Mapping signals from one board's connector to another to verify mating and pinout accuracy. Unified Library Management: Ensuring that component symbols and footprints are consistent across the entire multi-board project. Nine Dot Connects +1 B. 3D Integration and Collision Detection A primary benefit of MBA software is the ability to place and check components in a 3D environment. Altium Mechanical Clearance: Visualizing obstacles to avoid errors during initial placement. Collision Testing: Checking for intersections between 3D bodies, such as tall capacitors hitting a neighboring board or enclosure wall. Connector Mating: Verifying that male/female connectors align perfectly in 3D space. Altium +2 C. Rigidity and Stability Because multi-board systems often face mechanical stress, the assembly must account for: Vibration Mitigation: The enclosure and mounting points must protect the assembly from shock. Panelization: Ensuring the panel design is not too large for the board thickness to prevent "bounce" or flexibility issues during manufacturing. Cadence Design Systems +1 3. Documentation and Manufacturing Handoff Detailed documentation is essential to prevent assembly errors at the contract manufacturer (CM). 11 sites The Role of CAD in Design: Synthesizing ECAD and MCAD Feb 16, 2023 —
