Many of you already received communications about the move of the Cadence user community into cadence.com. And many of you have already joined, with over 4000 registrations in the first two weeks.

The new Cadence Community enhances the ability of Cadence users to connect and collaborate. In addition to moving the community into cadence.com -- enabling single sign-on for community, Sourcelink and Cadence events -- the new site is organized around nine technology segments, giving you easy access to product information, training, forums and blogs. Some of the new features include:
  • Ability to respond to posts via e-mail
  • Technology-specific blogs
  • Latest Web 2.0 social networking capabilities
  • Public profile options
  • Private messaging
  • Friends lists
Visit the new Cadence Community today at www.cadence.com/community and join the discussions!

Registration note: Due to the scope of the enhancements and the new SSO registration system, we were not able to migrate existing cdnusers.org member accounts. So new registrations are required, but this enables a broader set of functionality we think you'll enjoy.

Forum note: Under the guidance of forum moderators, we have taken the 20+ cdnusers.org forums and consolidated them into 11 forums on the new site. Posts have been brought over so you can leverage that posting history. CDNusers forums will be set to read only starting 7/30, and cdnusers.org will be redirected to the new community on 8/4.

Best regards,
Mike and Tom

I know I can create a padstack to accomplish this but, is there any way to select certain pins (press fit) within PCB Editor and attach a no-suppress property to them?

I'm not sure what you mean by ""press Fit"" pins or how you have managed to utilize a pad stack to get your results.
If you explain it in more detail as to what you would like to see, I'm might be able to request an enhancement to
implement what you would like to see.

According to IPC, components with compliant (press fit) pins should have full padstacks because of the force needed to insert the pins into the hole. If you suppress unconnected pads on internal layers, you could potentially push the barrel out of the hole. The pads act as an 'anchor' for the barrel of the hole.

What I was asking was, is there any way to 'edit properties' on specific pins within the design and attach a 'no-suppress' property to those pins. As far as I can tell, you can't, but your probably better off modifying the padstack and setting the internal layers to 'fixed' and then refresh padstacks in the symbol. This way you don't have to remember to do it for every design.
