Success Story

Malvern Instruments have benefited from CADSTAR Board Modeler Lite by enhancing data collaboration between ECAD and MCAD, and improving manufacturing data.

As Electronics engineers we often perceive the electronics design encapsulated in the PCB assembly to be the core of the product. At Malvern Instruments, however, that is not the case as their advanced instruments are primarily mechanical in nature so the electronics forms a critical, but secondary, element of the finished product.


Once the physical characteristics of the board profile, keep-out areas and critical placements have been imported from the mechanical drawing and combined with design connectivity from the engineering schematic, the PCB Design Engineer can start the layout process.

When the initial component placement is complete the design needs to be checked to ensure no physical constraints have been broken. This is easily verified by creating a simple 3D model in Board Modeler Lite, importing the enclosure as a constraint, and using the powerful checking tools to ensure no collisions have been created. If any violations are detected, changes can be made in the 3D environment and automatically back-annotated to the PCB layout.

If more accuracy is required the simple block models can be replaced by accurate 3D representations that can either be imported from the wide range of freely available parts or created in Board Modeler Lite using the built-in parametric model generator.

Board Modeler Lite

Board Modeler Lite is a unique, stand-alone solution that bridges the gap between electronic and mechanical design. It is the most effective design review tool available, displaying both electronic and mechanical information in a single environment. Board Modeler Lite reduces iterations between departments, decreases duplication of effort, and provides greater accuracy.


  • The initial timescale was 36 months, however, the update has just been completed, 12 months ahead of schedule thanks in part to CADSTAR technology.
  • The Turret Control Computer now houses 98% less wiring than before.
  • Avoid costly mistakes and ensure the electronics fit the space constraints available.

“Using Board Modeler Lite in conjunction with CADSTAR PCB design and our 3D mechanical software, we can avoid costly mistakes and ensure the electronics fit the space constraints available. Our latest project included more than 20 PCBs, all of which fitted first time. The ability to fully characterise the 3D board with accurate models, plus the ability to check for and resolve clearance errors, helps us produce better documentation for test and assembly, and most importantly ensures we get easily manufacturable products in a shorter time. We also find that Board Modeler Lite is very useful as a design tool. It allows us to try multiple design ideas and develop virtual prototypes so that we can see what will and won’t work before they go to manufacture – which obviously reduces our costs.”
