Jack, you've been the "new guy" for the eight years or so I've known you.
Hopefully you can settle down now :-)

Just remember copper clearance and solder mask on all of the layers based on
the size of the screw head, not the hole. Your note sounds fine.

Your old buddy,

Subject: [DC] PCB countersunk holes


I have never been asked to provide countersink mounting holes on a PCB
before.
Since I have never had a drafting class, can I ask if any of you typically
do this?
I was just going to add a note to the fabrication dwg saying:

x.) Countersink mounting holes (8X) 82 degrees x .230 on component side.

Is this adequate?
Are there any "gotchas" I need to keep in mind?

Jack (the new guy)
