This topic describes a typical procedure to define a new assembly using Gerber data. FactoryLogix uses a series of wizards to guide you through the steps to create a new product or assembly in the NPI client application.
Gerber files commonly used in PCB manufacturing are machine programs for photo plotters. Essentially vector-based drawings of each layer of the PCB, these files require additional processing referred to as digitizing in order to be used in FactoryLogix. The Gerber digitizer in FactoryLogix has several tools to assist with the digitizing process.
There are two main types of Gerber data:
RS-274D - these files require a separate aperture list which could be one list for all the Gerber files or one list for each Gerber file
RS-274X - these files contain embedded aperture lists
Create a new assembly
When you create a new assembly, only a name, revision level, and process revision level
...
are required. Other options allow you to assign a customer to the assembly and copy a BOM/CAD and/or a process definition from an existing assembly.
Log into
...
the NPI
...
client application.
Select Process Engineering
...
> New Assembly.
...
Enter a name for
...
the New Assembly

Load design files
The Load Design Files page is where you select a BOM, Gerber, and other supporting files for a new assembly. When you import files and folders, options at the top of the page are available to help you organize, select, and/or remove the necessary files and folders for the new assembly: View Item, Remove Item, Undo Delete, Select All, Remove All, Select Group, Remove Group. The available options depend on the files or folders selected on the page; use the check boxes to select or deselect specific files.
There are four general categories of files you can load:
BOM
ECAD
Gerber
Other
When you load design files, be sure to look in the File Type column and verify that each file type is identified correctly—especially BOM files that typically require cleaning and formatting. For example, a BOM may be loaded as an Unknown file type. Use the File Type drop-down to change design files to the appropriate (specific) file type for the product or assembly.
...
Note
...
For BOM files created in Microsoft Excel, FactoryLogix supports only Excel version 5.0 and higher files (*.xlsx format).
| Tip |
|---|
...
Tip You can also load a *.zip design file—the system will extract and list all the files contained in the *.zip file automatically. |
Under Importing File List on the right side of the page, select Add File, locate and select the BOM file for the new assembly, then
...
select Open.
...
Note
...
If you already have a folder containing the desired BOM and other supporting files for the assembly, select Add Folder in Step 1, then locate and select the folder to import. (The wizard page that displays after the import step depends on whether you import files one-by-one or all at once in a folder or *.zip file.)
If the BOM file isn't recognized, it displays as type Other. To change the file type for the BOM, select BOM File and note the addition of a new button for BOM Formatting.
| Info |

BOM text formatting
When you import a text-based BOM file to use for a new process definition, the BOM Text Formatting page displays in the Process Definition wizard.
Under Parsing Options, do one of the following to format the text file:
Select Fixed Width to create fixed-width columns for the BOM data, then enter the desired column width.
Select Delimited, then use the drop-down to select the delimiter used in the BOM file to separate the various data values (comma, semicolon, colon, bar, tab, double tab, space, or
...
| icon | false |
|---|---|
| title | Note: |
double space). If a delimited character
...
isn’t listed, you can enter it in the Delimited drop-down.
To save your text formatting for use with other text-based BOM files you import, select the Save
...
button, enter a Template Name, then select OK.
...
Note
...
If you apply a template to a text-based BOM but then decide you don't want to use the template, select the Delete
...
button.
When you finish formatting the BOM text, select Next to move to the BOM Formatting page where you can make additional modifications.
BOM worksheet selection
When you import a worksheet-based BOM file containing more than one tab/worksheet to use for a new process definition, the BOM Worksheet Selection option displays in the Process Definition wizard.
After you select the BOM worksheet file, select BOM Worksheet Selection on the left side of the wizard page.
...
The BOM Worksheet Selection page displays, allowing you to select the desired BOM worksheet for this assembly. The following illustration shows an Excel file BOM with two worksheets: AEGIS_CONSOLE$ and Sheet 1$.
...
Under Worksheets, select the worksheet that contains the BOM data for this assembly.
The Preview pane on the right side of the window shows you what the worksheet BOM looks like before further editing.Select Next to move to the next wizard page.
BOM formatting
When you create a new part or assembly in FactoryLogix NPI, the BOM Formatting page of the wizard lets you process complex BOM information into a more usable and organized format. The main goal
...
of BOM cleaning is to define the fields (columns) to import from the BOM and remove unnecessary information to make the BOM more readable before you publish it.
FactoryLogix has powerful tools to help you clean BOM files of non-essential information and add formatting to make the BOM easier to read and use. When you format one type of BOM, FactoryLogix has the ability to "remember" the cleaning process—that cleaning process can be applied automatically in the future for similar BOM files, saving you valuable time and effort.
