pcbTraceCustom

Create custom trace

Since R2025a

Description

Use the pcbTraceCustom object to create custom traces for transmission lines.

Creation

Syntax

trace = pcbTraceCustom

trace = pcbTraceCustom(PropertyName=Value)

Description

trace = pcbTraceCustom creates a trace in microstrip form with default properties.

trace = pcbTraceCustom(PropertyName=Value) sets Properties using one or more property name-value arguments. For example, trace = pcbTraceCustom(TraceType = traceTapered) creates a custom trace with a tapered trace.

Properties

TraceShape — Shape of trace

traceStep (default) | shape object

Trace shape specified as a shape object.

Note

traceLine, traceRectangular, and tracePoint shapes are not supported.

Example: trace = pcbTraceCustom(TraceShape=traceRectanglular)

Data Types: string

Height — Height of trace from ground plane

0.254e-3 (default) | scalar

Height of the trace above the ground plane specified in meters.

Example: trace = pcbTraceCustom(Height=0.259e-3)

Data Types: double

GroundPlaneWidth — Width of ground plane

0.020 (default) | scalar

Width of the ground plane specified in meters.

Example: trace = pcbTraceCustom(Height=0.025)

Data Types: double

Conductor — Type of metal used in conducting layers

'PEC' (default) | metal object

Type of metal used in conducting layers, specified as a metal object. For more information see metal. The type of metal in a micrpcbTraceCustom object with default properties is PEC.

Example: m = metal('Copper');trace = pcbTraceCustom(Conductor=m)

Data Types: string

Substrate — Type of dielectric material

'Teflon' (default) | dielectric object

Type of dielectric material used as a substrate, specified as a dielectric object. For more information, see dielectric. The dielectric material in a pcbTraceCustom object with default properties is Teflon.

Example: d = dielectric('FR4');trace = pcbTraceCustom(Substrate=d)

Data Types: string

Examples

Create and Visualize a Custom PCB Trace

This example shows the creation of a default custom PCB Trace object

Create the object

trace = pcbTraceCustom;

Visualize the object

show(trace)

Create and Vizualize a PCB Custom Trace with a Tapered Trace

This example shows how to create a PCB custom trace with a specified property

Create the object

Set the Trace Shape property to a tapered trace

trace = pcbTraceCustom(TraceShape=traceTapered)

trace = 
  pcbTraceCustom with properties:

          TraceShape: [1×1 traceTapered]
              Height: 2.5400e-04
    GroundPlaneWidth: 0.0200
           Substrate: [1×1 dielectric]
           Conductor: [1×1 metal]

Vizualize the object

Use the show function to vizualize the object

show(trace)
