PCB Stack

Video: Perform a thermal analysis on a component and printed circuit board

Use the PCB Stack physical property to:

• Model a printed circuit board’s complex in-plane conductivity in each layer and across layers without using 3D solid elements.

• Model the stack of a Printed Circuit Board (PCB) by defining the layers and the order of the layers. Model each layer by defining its materials and the trace area coverage percentage.

• Model detailed traces and vias information from ECAD models that are imported using the PCB Exchange application.

• Calculate and post process a detailed temperature profile in each layer that you define inside the PCB Layer modeling object.

Sample PCB Stack with top and bottom layers

The PCB Stack physical property applies only to 2D mesh collectors.

When you define the stack sequence, the first PCB Layer modeling object corresponds to the bottom layer (Layer 1).

PCB Stack orientation

A PCB Stack physical property contains PCB Layer and PCB Via modeling objects.

Note:

• You must define one or more PCB Layer modeling objects. A PCB Via modeling object is not required.

To model thermal and flow phenomena on a printed circuit board, you must create a Printed Circuit Board simulation object in addition to the PCB Stack physical property. A PCB Stack physical property is created automatically by PCB Exchange when you use the Thermal Solution command.
