Update 16: Updated plug-ins from release 10.818.23272 to 10.890.23450

Date: 6 February 2012

Key highlights

Improvement to impedance and width calculations

This release delivers enhanced control for High Speed signal routing in Altium Designer through improvements in the application of trace routing rule calculations. These can be found in the Impedance Formula Editor in the Layer Stack Manager, which now offers more accurate default formulas for impedance and width calculations. View BugCrunch report #201

Specifically, to provide better control for material layers, new variable keywords have been added to the equation Helper including:

ErAbove; ErBelow – define material above or below the trace.
DielectricHeightAbove; DielectricHeightBelow – define dielectric thickness above or below the trace.

Export Free Pad Holes

Altium Designer's support for STEP files allows detailed and accurate modeling data to be interchanged with mechanical CAD and 3D modeling programs. When defining an OutJob for exporting STEP files, a new option has been added to "Export Free Pad Holes" in addition to the existing options to export electrical and mechanical component holes. Designers using Free Pad Holes for board mounting or other purposes can now easily pass this information into the MCAD domain via an exported STEP file.
