Model Your PCB Supports with MCAD Integration in Altium Designer

Every electronic device needs an enclosure, which means some supports will be needed for the PCB to fit and secure the PCB into its enclosure. It sounds simple, but including precise PCB supports requires careful mechanical modeling to ensure there is no interference between components and various mechanical elements. This becomes even more important when we look at flex and rigid-flex board, which may need to move and bend during operation.

Altium Designer is the only PCB design application that helps solve this problem with a complete set of MCAD tools. Simply press a key on your keyboard, and you’ll see an ultra-accurate 3D model of your circuit board with realistic detail. You can also place your PCB supports, examine conformance to an enclosure, and export your PCB for modeling in an external MCAD application like SolidWorks. Altium Designer gives you everything you need to carefully design the mechanical aspects of your next circuit board.

ALTIUM DESIGNER®

The only PCB design application that includes MCAD features for PCB supports design, 3D component layout and routing, and exporting to other MCAD applications.

Any new modern circuit board design contains a broad range of components, and designers need to consider how their board will mount to its enclosure or how it fits in a multiboard assembly. Components like passives and specialized ICs or SoCs are standard in most designs, but PCB supports provide the attachment to your PCB enclosure. With the right design tools, a PCB layout can be designed with more than just mounting holes.

Instead of placing simple mounting holes in a PCB layout, designers can place a range of mechanical elements like connectors, screws, bolts, guide keys, posts, and much more. Doing this correctly requires a set of MCAD features, and these same MCAD tools can be used for much more complex PCB design tasks. Here’s why your design team needs a complete set of ECAD and MCAD tools and why these tools work best when they are integrated into the same design application.

Why PCB Designers Need MCAD Features

It seems like every year, new designs become more complex and contain more features packed into a smaller space. Every new design now have very specific electrical and mechanical requirements that need to be followed, yet most designers are still forced to use different programs to confront design challenges in each area. This reduces designer productivity and creates the potential for errors as neither program can work of the same file formats or design rules.

Today’s designers need a unified ECAD and MCAD environment to help them design and place mechanical supports in their board. When designers can access these features within their PCB design software, it’s easy to prevent mechanical interferences in simple rigid boards and in complex flex, rigid-flex, and multiboard assemblies.

Design Any Complex Assembly in Altium Designer

The ECAD and MCAD tools in Altium Designer are fully integrated, meaning users can access mechanical design tools alongside industry-standard ECAD features. This is exactly what designers need to create high-quality flex, rigid-flex, and multiboard assemblies. Designers can user Altium Designer’s comprehensive ECAD toolset to create circuit board layouts, and they can define board assemblies with MCAD tools in a single application.

Altium Designer integrates design data across tools and management features.

Placing and Viewing PCB Supports in 3D MCAD Tools

MCAD tools work with a number of proprietary and vendor-neutral file formats, but not all ECAD applications provide this same type of support. As a PCB design application that also supports mechanical modeling, Altium Designer also allows you to import 3D models of PCB supports and place them in your layout. Popular vendor-neutral file formats are supported, and connector extensions are available for integration with popular MCAD applications. What sets Altium Designer apart is the integration of these MCAD features alongside your ECAD features, allowing you to place any PCB supports or other mechanical components into your PCB layout alongside your electrical components.

Extreme ECAD/MCAD Integration in Altium Designer

Thanks to Altium Designer’s extreme level of integration, it’s easy to place any PCB support element or other mechanical element in a PCB layout without using a separate program. STEP models for these components can be instantly imported into Altium Designer and placed in a PCB layout by attaching these models to a mechanical component. The PCB support component can then be used in later designs as needed.

Altium Designer is one of the few design platforms that also supports a simplified integration with Solidworks. The Solidworks connector extension is available to all Altium Designer users, and this extension allows a circuit board layout or multiboard assembly to be exported for use in Solidworks. Designers can then create and model enclosures for their boards while also checking for mechanical interferences and verifying PCB supports placement.

Mechanical elements like screws, testpoints, connectors, and much more can be placed in your PCB layout and viewed in 3D.

Altium Designer’s Unified Design Environment

Altium Designer provides more than MCAD tools alongside PCB layout features. Altium Designer provides everything needed to take a new design from concept to finished product, and all without needing to exit the main application. Users can access the following set of design features:

  • A powerful schematic editor with a complete set CAD tools
  • 2D and 3D PCB layout features that provide ultra-accurate component placement
  • A simple but powerful routing engine that supports multi-Gbps signaling standards
  • Pre-layout and post-layout simulation and analysis packages
  • A complete set of manufacturing documentation tools and generators
  • Access to a set of managed component libraries with PCB footprints and ECAD data
  • And much more…

The power of Altium Designer lies in its rules-driven design engine, which automatically evaluates a layout as it’s created. This powerful engine allows every tool in Altium Designer to work off the same set of design rules and checks a design instantly during layout. PCB designers know that Altium Designer helps them stay productive.

Altium has Created a Complete PCB Design Platform

Thanks to the complete set of electrical and mechanical design tools, as well as integration with industry standard programs like Solidworks, Altium Designer users can take a new circuit board throughout the entire design process. Every aspect of simple circuit boards, complex multiboard PCBAs, and flex/rigid-flex circuit boards can be designed with extreme accuracy. Don’t get stuck using other design platforms that don’t help you stay productive, use the complete set of world-class design tools in Altium Designer.
