Packages - SOT
SOT enables you to create geometry and boundary conditions to represent an plastic encapsulated small outline transistor.
Use the navigation arrows on the image below to view each tab.
| Name | The Name appears in the Project Manager window, history tree, and 3D Modeler window. |
| Type | Type specifies whether the package is type SOT-23, SOT-223, or SOT-89. |
| Plane | Plane specifies the plane on which to create the package. |
| Mold Location | Under Location, specify the starting coordinates for the mold 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 Mold Height depends on the selected Plane. |
| Air Gap under Mold | Air Gap under Mold specifies the airgap under the mold. |
| Die Information | Under Die Information, specify the die height, material, and power. Also, specify the thickness and material of the die attach. |
| Lead Frame Information | Under Lead Frame Information, specify the lead frame length, width, thickness, and offset. |
| Lead Material | Lead Material specifies the material of the leads. |
| Location of Lead 2 | Under Location of Lead 2, specify the coordinate direction for the location of lead 2. |
| Lead Dimensions | Under Lead Dimensions, specify the lead thickness, widths, pitch, span, footprint, and projected length. |
