Specifying Terminal Numbering and Package Material

PartQuest Portal Subscription: Essential tier

You use the Details page of the Footprint Creator wizard to specify the terminal (pin) numbering pattern and the package body material of a custom footprint you create for a PartQuest Portal part.

As you build a package, the right panel displays a top-down, two-dimensional (2D) preview of the package terminals. The position and terminals numbers appear as you specify them.

Tip

For more information about a terminal numbering or package material option, click the information icon () to display a cross reference to the section of the JEDEC standard that defines terminal numbering patterns and package body materials.

Prerequisites

  • You have logged into the PartQuest Portal website with your Siemens account. See “Signing In to the PartQuest Portal Application

  • You have successfully defined the terminals of the footprint in the Terminals page of the Footprint Creator wizard.

  • You have detailed package information from the part manufacturer.

Procedure

  1. From the Terminal Numbering Pattern section, choose a pattern.

    If a message appears to click the first terminal of the sequence, from the 2D package preview, click the first terminal.

    The wizard displays a sequence of terminal (pin) numbers in the 2D package preview.

  2. (Optional) Some complex packages require you to specify the location and label pattern of terminals. You use the 2D package preview to specify complex number value patterns.

    From the 2D package preview, perform any of the following:

    If you want to...

    Do the following...

    Set terminal (pin) number 1

    Right-click a terminal, and then choose the Set as First Terminal popup menu item.

    Select a range of terminals

    Click a terminal and then shift-click the last terminal in the range.

    Selected terminals appear shaded.

    Select a set of terminals

    Ctrl-click one or more terminals.

    Selected terminals appear shaded.

    Unselect terminals

    Right-click and choose the Clear Selection popup menu item.

    Reset terminal numbering

    Right-click a terminal, and then choose the Reset Number popup menu item.

    Specify a terminal number

    Click a terminal, and then from the Terminal Numbering Pattern section, click either the Assign button or a pattern button, select a value pattern from the dropdown list, and then type a value.

    If you choose a numerical value pattern, you can specify ranged numerical values (1-100), a list of comma-separated values (1,2,3), or a combination of both.

    If you choose an alphabetical value pattern, you can specify an upper or lower case range of alphabetic values (A-Z), a list of comma-separated, upper or lower case alphabetic values (A,B,C), or a combination of both. You can specify values to include and exclude.

    If you choose a custom value pattern, you can specify a list of comma separated values.

    Skip a terminal in the sequence of numbers

    Right-click a terminal, and then choose the Set as Missing popup menu item.

    Missing pins appear with a dashed outline.

    You can assign a number to a missing terminal but the wizard does not create a footprint pad it.

    Delete a terminal

    Right-click a terminal, and then choose the Set as Deleted popup menu item.

    Deleted pins appear with a dashed outline.

    You cannot assign a number to a deleted terminal and the wizard does not create a footprint pad for it.

    Reset a missing or deleted terminal

    Right-click a missing or deleted terminal, and then choose the Reset Missing/Deleted popup menu item.

    The wizard makes the terminal available for numbering.

    Exclude a terminal from numbering

    Right-click a terminal, and then choose the Exclude from Numbering popup menu item.

    The wizard labels excluded terminals as “NAnum” wherenum is a numeric suffix and creates a footprint pad for it.

  3. From the Package-body Material section, select the primary material that makes up the package body.
  4. Click Continue to Validate.

    Either the Footprint Creator wizard Validate page appears or a popup error message appears that indicates the terminal numbers that are missing or have conflicting values. Terminal numbering options with errors appear in red on the Details page.

Results

The wizard generates the terminal number pattern that you specified. You are ready to examine and validate the footprint.
