Where is a via naming convention at?

The anti-pad is for both Positive and Negative planes and it represents a very important value in the pad stack, especially for vias.

If the anti-pad diameter should not be larger than the pad annular ring + trace space.

You do not want to run high speed signal traces over a plane anti-pad. The plane is the signal return path and trace couples with the plane.

In the via pad stack, you have to define the pad, hole, anti-pad and direct plane connect (flood over) for a normal copper pour plane flood.

Isn't it time to drop the zz from the following via naming conventinon:  via-xx-yy-zz  where xx is the pad diameter, yy is the hole diameter and zz is the anti-pad diameter?  We haven't been using negative planes in years and I believe most EDA tools have gotten away from them too.  Thoughts.]]> Tue, 13 Dec 2016 14:05:40 +0000 https://www.PCBLibraries.com/forum/via-naming-convention_topic2038_post8354.html#8354 <![CDATA[OrCAD Layout : OrCAD Footprint for Hirose Connectors]]> https://www.PCBLibraries.com/forum/orcad-footprint-for-hirose-connectors_topic1246_post4895.html#4895 Author: Nick B

The FP Designer feature in the PCB Library Expert can create every Footprint for every Hirose connector.

The Parts on Demand (POD) will have hundreds of thousands for mfr. part numbers and we'll try to get several thousand Hirose connectors uploaded in FPX format for free download for the Library Expert users.
