thanks a lot :) it is very clear to understand. I exported those layers for the 1st pcb of my project.
I'm going to post another question about freerouting.net and native autorouter in kicad :) talks soon julien --- In [email protected], "gharlandau" <gharlan...@...> wrote: > > Hopefully the following details will provide some additional clarification > about the differing natures and roles of the solder mask and paste mask > layers. > > An example of where details on a solder mask layer and (associated) paste > mask layer would *not* be the same involves (surface mount) pads which form > part of an edge connector.
