Syntax

propVal = getantipads(pcbobject)

Description

propVal = getantipads(pcbobject) generates an antipads stack based on the number of signal vias and the number of conductive layers. propVal can be optionally customized and assigned to SignalViaAntipad.

This example shows how to use the getantipads function to generate an antipads stack

via = viaSingleEnded
via = 
  viaSingleEnded with properties:

                        GroundLayer: [3 5 9]
                          Conductor: [1×1 metal]

   Dielectric Layers
                          Substrate: [1×1 dielectric]

show(via)

Figure contains an axes object. The axes object with title viaSingleEnded element, xlabel x (mm), ylabel y (mm) contains 15 objects of type patch, surface. These objects represent Copper, feed, FR4, \infty board edge.

Example: via=viaSingleEnded; propVal = getantipads(via)

Data Types: sigle ended via

Output Arguments
