Creepage/Clearance PCB-to-PCB and PCB-to-Housing
« on: August 10, 2020, 10:15:17 am »
Hello,

I've been a long time silent reader of the forum, but this is my first post.

I'm dealing with the insulation coordination (clearance and creepage checks) for several AC-DC and DC-DC (~ 1kV DC) converters, each one of them consisting of several PCBs tightly fit in an enclosure.
One of the main standars I have to comply with is the EN 60664.
For the PCBs design I am working with Altium v20.

My main question is the following: has anyone encountered an automated way of defining and performing clearance/creepage rules checks for tracks and pads across PCBs or between a track/connector in a PCB and the housing connected to PE?

I can define a set or rules for each PCB and this works fine for that PCB alone, but then for the physical aseembly process some violations of the minimum distances arise due to PCB-PCB or PCB-Housing interaction.

Altium has introduced their Multi-Board projets which allow to perform 3D collision tests between PCBs, but no electrical rules checks so far.
The possibility of exporting the .STEP file to a CAD software like solidworks and check the assembly there (insulation wise) is not conclusive.

I wanted to know if anyone has encountered this issue and a potential solution, within Altium or outside it, I just want to hear your experience on the topic.

Thanks in advance
Cheers
