Packages - Network Model - BGA_Network

Packages - Network Model - BGA_Network enables you to create geometry and boundary conditions to represent a ball grid array network.

Name	The Name appears in the Project Manager window, history tree, and 3D Modeler window.
Plane	Plane specifies the plane on which to create the package.
Junction Details	Under Junction Details, specify the junction power and capacity.
Board Side	Under Board Side, specify which side of the package the board is located.
Position and Size	Under Position and Size, specify the starting coordinates for the package geometry relative to center of the 3D Modeler.Also specify the length of the package and leads in each coordinate direction.
Top Inner Region	Under Top Inner Region, specify the length of the inner region on the top side of the package.
Bottom Inner Region	Under Bottom Inner Region, specify the length of the inner region on the bottom side of the package.

Solder

Under Solder, specify whether or not to model a solder block and specify the number of rows, rows to be suppressed, and number of central rows. Also, specify the dimensions of the solder balls, including pitch, diameter, and height. Also, specify the material for the solder balls.

Network

On the Network tab, enter the thermal resistances for the network nodes.
