The pad and package dimensions and spacing are used primarily to showcase an effective design procedure in Ultiboard. Please note: The landpattern you are creating in this tutorial is not a commercial package.

Associating a landpattern with a Multisim symbol.

Saving the landpattern to the Ultiboard and Multisim database.

Using the Ruler Bars for Object Positioning.

This landpattern is created manually so as to precisely define the shape, size, and dimensions of a Surface Mount Device (SMD).The article will outline the steps to create a custom 20-pin SMD landpattern that can be associated with the custom component created in the Creating a Custom Component in NI Multisim tutorial.

This tutorial, Part 2 , outlines how to create a custom Ultiboard landpattern for layout. In this part, a pre-defined database footprint, or landpattern, is associated with the newly created component. Part 1, explains how to utilize the Component Wizard to create a custom component with a schematic symbol and SPICE simulation model. These two tutorials form a complete, A to Z guide for component creation, from the schematic symbol and simulation model to the final PCB landpattern.Ĭreating a Custom Component in NI Multisim and Create a Custom Component in NI Ultiboard are your resources on how to intuitively and quickly learn how to create your own custom components. The highly flexible database manager makes it easy to add a new SPICE simulation model, to a custom defined schematic symbol which can then transfer an accurate footprint to layout. The schematic symbol in Multisim is associated with an Ultiboard landpattern that is transferred to layout. NI Multisim and NI Ultiboard provide an integrated platform to design, simulate and lay out a complete Printed Circuit Board (PCB).
