Packages - FPBGA

FPBGA enables you to create geometry and boundary conditions to represent a fine pitch ball grid array package.

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.
Location	Under Location, specify the starting coordinates for the package geometry relative to center of the 3D Modeler.
Size	Under Size, specify the length of the package in each coordinate direction. The coordinate direction represented by Package Thickness depends on the selected Plane.
Model Specs	Under Model Specs, specify the Model Type as Detailed, Compact Conduction Model (CCM), Characterize JC, or Characterize JB and select a Symmetry.

Substrate	Under Substrate, specify the Number of Layers, Substrate Thickness, and Substrate Material.
Trace	Under Trace, specify the coverage percentage for the top trace, bottom trace, first internal layer, and second internal layer. Also specify the Trace Thickness and Trace Material.
Vias	Under Vias, specify the number of vias and via diameter and thickness.

Distribution	Under Distribution, enter the number of rows for solder balls, the Array Type. For a Peripheral Array, specify the number of rows to be suppressed and number of central rows.
Ball	Under Ball, specify the dimensions of the solder balls, including pitch, diameter, and height. Also, specify the material for the solder balls.
Mask	Under Mask, enter the solder ball mask thickness and material.

Die	Under Die, specify the length of the die in each coordinate direction. The coordinate direction represented by Height depends on the selected Plane. Also, specify the die power and material.
Die Paddle	Under Die Paddle, specify the length of the die paddle in each coordinate direction. The coordinate direction represented by Thickness depends on the selected Plane. Also, specify the die paddle material.
Die Attach	Under Die Attach, specify the thickness of the die attach material and the material.

Mold	Under Mold, select the material for the mold.
Wire Bonds	Under Wire Bonds, specify the diameter, average length, and material of the of the wire bonds.
