ECAD-MCAD Design Challenges § Problems faced in the design of products which have both Mechanical and Electrical Components: Thermal analysis of singular or multiple boards within their enclosures Small enclosures require accurate placement, keepins, keepouts. Connectors and mounting holes for the connector must move as one Assembly screw shorting electrical connection on PCB. 2 Alignment of optical sensing devices.

ECAD-MCAD Design Challenges A complex milled shield must align exactly with the PCB. Detailed electrical and mechanical data is required for accurate thermal or EMI analysis. Complete product modelling and some way of managing the process for traceability to reduce development time and prototyping costs. 3

EDMD – The Next Generation of ECAD/MCAD Collaboration § Advantages that EDMD brings over the current methodologies: § Incremental design allowing closer collaboration between the MCAD and ECAD engineer. § Ability to send notes/messages between MCAD and ECAD so they are aware of why changes are made. § Traceability of what was changed, by who, and why the change was made. § Developed by the Pro. STEP IVIP organization and is an active format. § More detail (such as copper and trace information) can be sent in the latest version of the format. 4
