Packages - DUAL

DUAL enables you to create geometry and boundary conditions to represent a DUAL 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 or Compact Conduction Model (CCM) and select a Symmetry.

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.

Leads

Under Leads, specify the number of leads, the direction in which the leads will point, the lead thickness and width, material, foot length, and airgap under the package.
