What do you mean by clearance around the hole? If you mean the outer diameter of the countersink, that would be determined by the diameter of the head of the screw that you will put in the hole. -- Peter Bennett TRIUMF 4004 Wesbrook Mall, Vancouver, BC, Canada GPS and NMEA info and programs: http://vancouver-webpages.com/peter/index.html * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * To post a message: mailto:[EMAIL PROTECTED] * * To leave this list visit: * http://www.techservinc.com/protelusers/leave.html * * Contact the list manager: * mailto:[EMAIL PROTECTED] * * Forum Guidelines Rules: * http://www.techservinc.com/protelusers/forumrules.html * * Browse or Search previous postings: * http://www.mail-archive.com/proteledaforum@techservinc.com * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *

Re: [PEDA] Countersunk holes
Edi, A countersunk hole is simply a normal right cylindrical through-hole with an additional right conical section removed for accepting a flat head screw. The cone angle is typically 82 or 100 degrees. The diameter of the smaller end of the conical section is the same size as the hole and the diameter of the larger end depends on both the angle and the thickness of the material. The creation of a countersunk hole is performed using a special countersink drill bit or a drill bit and angle end mill in combination. -Original Message- From: Edi Im Hof [mailto:[EMAIL PROTECTED]] Sent: Friday, January 11, 2002 07:28 To: Protel EDA Forum Subject: Re: [PEDA] Countersunk holes At 12:39 11.01.02 +0100, you wrote: - Original Message - From: Edi Im Hof [EMAIL PROTECTED] Thanks to all for the answers.

Re: [PEDA] Countersunk holes
If it's for mounting holes then just ensure the clearance is sufficient and I can't see any problem. I've used csk holes for boards where vertical clearance is very tight. Steve.

Re: [PEDA] Countersunk holes
Sean. Yup been there done that. It worked out very well, the product is in production now, with no problems, at least not do to the contersunk holes anyway. Just talk to your fab house. I was doing a quite intelligent fan tray unit that had major height clearance issues so the PCB became an integral part of fan moutning etc. There was very little component area left on the board after all th eholes that were in it. Critical cooling issues. Countersunk holes were in fact needed. Dimension them just like you would in a piece of metal. But keep mind of what material would be left based on board thickness and type of coutersink etc. If I remember correctly they were considering plating these holes for chassis ground contact too. I'm not sure whether they ended up doing that or not but I believe th efab vendor said it was doable. Bob Robert M. Wolfe, C.I.D.

Re: [PEDA] Countersunk holes
Sean, I believe they can be plated but in previous post about fan tray a countersink for a flat head screws was used, and again I believe the answer was they could do it, not as sure about if you are looking at a countersink with verticle entry on edges. There might be a build up of in the corneres?? Which if countersink is big enough that may not be an issue. Talk to your fab vendor. Also another post point out a good point to make sure of proper clearance on all layers. Bob Robert M.

Re: [PEDA] Countersunk holes
I would forsee no technical problems in plating a countersunk hole, assuming that the boring is done before copper plating. As long as that hole processing comes before electroless copper, it *will* be plated. I suppose some processes might take the copper back if the bore wall was not protected during etch, but assuming that pad area in the artwork covered the bore area, I'd expect it to work. If you *don't* have pad there, then there might be problems. I would suggest, for fabricator convenience, using a unique hole size for the countersunk holes; a fab note can then refer to that nominal hole size and give special instructions. I'd make the hole size (what PRotel thinks is the hole) as large as the bore max diameter and the pad larger than that, this will ensure clearance on all layers including negative planes; I would not go below this in hole or pad size unless it was absolutely necessary, in which case one would have to be more careful when checking the design.
