Area arround pin- PCB designer

KrzysztofB

Hello Everyone,

I have problem with pins that I used as mounting holes.

Some addidional copper void area is arround and I do not want it.

That component is not only mechanical pin, because I have added
it to schematic and grounded. 

Where I can find option to make that void area disabled?

I am using PCB Designer Professional 16.6.

Best regards,

Chris

  • There are two different possibilities.

    1. You define a pad (hole) without copper and include a keep-out area in order to prevent copper to reach the drill area.

    This pad is then used exclusively for mechanical holes (that has no pin number) Not connected to a net.

    Or

    2. You define a pad with copper the "normal" way and add this as a pin into the schematic and symbol. Then you will have a choise wether you want to connect it to a net (GND?). Handy for eg. DSUB-connectors that wants to have GND connected to the shell.

    In order to totally flood the copper in such a pad/mounting hole: Select EDIT | Properties, and select "PIN". There will be a list of possible properties, amongst them "Dyn_Thermal_Con_Type". Select "Full Contact".

    This can be set already at the symbol creation time when doing library work. Handy also for arbitrary GND-connected mouning holes that is to be added to a design.

  • You could also have a Route Keepout shape as part of the symbol. Open the filename.dra (mechanical symbol) and make sure all the layers are turned on, you should see a copper rectangular shape on Route_Keepout/All. Delete this and then save the symbol and refresh it in the design.
