Hi, I'm going through the final process on DRC and checking with the manufacturer's hole sizes. I realized I started to include a hole size that I can use on 4L but not supported on 2L. I'm trying to find a DRC setting to specify the minimal acceptable drill size.
Just wondering if anybody knows if there is one?
I feel there should be one, but I don't seem to find a place for it. I can see the Design Status Report that tells me how many there are - but not where they are and how to generate it. I'm actually generating a DRC error it by changing the annular hole size on the via with the smallest hole to generate an error - but that could have other impacts. Many thanks for any pointers.
There is no way of specifying a minimum hole size. In fact this allows you to set a hole size of zero if you want no hole at all. You could of course set up hole sizes you wish to use in different technology files, I.e 4 layer technology and 2 layer technology.
Thanks - thats why I couldn't find it :) It is working for me to have adjusted the annular ring size of the smaller via, that then causes an error. Then I can visually examine pads again. The issue overall of course is that I need to meet a spec - all drill holes a certain size or larger Neil
