I have a question regarding mechanical holes: How do I create "stepped holes"? (Hopefully this is the right expression!?)
What I mean: I want to create a bore hole with different diameters from both sides - for example the pcb has a thickness of 3mm. The hole should have a diameter of 10mm in the upper mm, afterwards it should have a diameter of 5mm for the remaining 2mm.
I need this for ceramic inlays. Our pcb manufacturer can do this - but how do I create that padstack?
Thanks in advance!
In reply to kabalee:
i need a hole like the one in the picture:
In reply to TooBorg:
Another method could be to create a through-hole of 5mm and a blind hole of 10mm (you probably would get a DRC that you could waive).
In reply to Randy R:
i chose to create those holes with the smallest diameter and with a big keepout. and then i will rely on an autocad drawing.
