One of the central features in the MECODES collaboration environment is the common PCB library management system. This is a key element in ECAD/MCAD collaboration. MECODES links ECAD footprints and schematic symbol from ECAD authoring tools with CATIA V5 or CATIA 3DEXPERIENCE 3D model of the electronic parts. MECODES delivers more than 3000 3D ECAD CATIA parts which are linked with ECAD library.
The PCB library has a component update feature for users who want to extend the library with new components or modify existing ones. One of the most important features is the link between 3D component representation (MCAD) and electrical component representation (ECAD) which includes a schematic symbol for each component. The created common library stores also the transformation matrix which is controlling the component placement into the model of CATIA V5 and 3DEXPERIENCE, thereby reducing the risk of misplacement of components on the PCB.
Because of the miniaturization and the very limited space in products clearance control is one of the most important features. It prevents clashes, reworks and enables higher quality products.
MECODES allows defining space and distance rules between:
- two ordinary components
- two electronic components of the same kind or different types
- any electronic components and any mechanical component and all of them with the housing
A challenging task in mounting real physical boards with the mechanical housing is to ensure that the PCBs fits the mounting constraints as well as the electrical and thermal requirements. Important electrical and thermal requirements are verified by the simulation composed mechanical and equipped PCB(s). It is essential to transfer the copper in all layers to receive realistic simulation results which will allow being produce integrated electro-mechanical products. The MECODES solution allows designers to implement in the integrated model all vias filled with copper in addition to the copper traces on the different layers of the PCB stack.
