Create a Color Coded step
A Color Coded step automates the color coding of parts to be placed or inspected and is typically used in PCB manufacturing. A Color Coded step type is used when some degree of automation needs to be added to the step and activity documents in the form of an active work instruction as shown in the following illustration. Color coded visuals are generated dynamically within a Color Coded step.
Log into the NPI client application.
Open a new process definition and create a new operation. (See Add a new operation to a process flow for more information.)
Double-click the operation to open it for editing.
Select the Add button under Step List in the Process tree, then select Color Coded Step.
Double-click the Color Coded step to open the Settings dialog.
Use the following tables to make your selections for the step on each tab of the Settings dialog.
When you're finished making selections for the step, select OK to confirm your choices.
Settings dialog - Basics tab
Option | Description |
---|
Name | The name of the step. To apply a step template to the step, select the Apply a Template button, select a step template, then select OK. To save the step as a step template, select the Save as Template button, enter a name for the template, then select OK.
For details about creating and saving step templates, see Create a process, step, or operation template. |
Default Instruction | Enter the default instruction for this step. |
Operator Interface Template | The Operator Interface template to apply to the step. See Operator Interface templates for more information. |
Assigned Workstation | The assigned workstation where the step and activities will be performed by a shop floor operator. See Create a factory and set up factory resources for more information. |
Any Order Mode (Activities can be viewed in any order) | All the activities associated with the step may be viewed in any order. |
Is Step Required? | The step cannot be skipped by a shop floor operator. |
Activities may be executed without starting a unit | Any activities associated with the step may be executed by a shop floor operator without first scanning or entering a UID to start the unit in production. |
Frequency | |
Do you want to require credentials? | |
Approval Process | Yes - An approval will be required for the specified activities before the step can be completed.
Select an approval process from the Approval Process drop-down. Select the activities that the approval will be required for: First Activity, Last Activity, or All Activities.
No - The shop floor operator won't be required to obtain an approval before completing the step and its activities.

Settings dialog - Color Coding tab
Option | Description |

Color Palette | The color palette to use for color coding parts. Select a color palette from the Palette Chooser drop-down. Select the Edit Color Palettes button to open the color palette editor where you can specify custom colors for parts.
To add, edit, or delete a color in the selected palette, select a color, then use the Add Color , Edit Color , or Delete Color button to make the desired changes. To change the name of a color palette, select the Change Palette Name button to the right of the Palette Chooser drop-down, enter a new name for the palette, then select OK.

Look Behind | The Look Behind feature is typically used in manual assembly operations where an assembler is shown the parts placed by the previous operator so that their work can be verified prior to performing their own tasks. Parts placed by the previous operator are color-coded/highlighted using a pre-selected Look Behind Color. |

Settings dialog - Activity Splitting tab
The Activity Splitting tab of the Settings dialog for a Color Coded step allows you to define or limit the number of color-coded parts to be displayed on each page. (Since the human eye can typically discern about 10 different colors at any given time, it is best to limit the Max Number of Items per Activity to no more than 10.) On this tab of the Settings dialog, you can also define the ordering and sorting of parts listed for each activity to help focus operator attention on a specific area of a PCB for placing or inspecting parts.
Option | Description |
---|
Group by | Side - (electronics) Specifies the side of the board to group activities by for color coding:
Mixed - Activities are grouped by both the top and bottom sides of the board. Top Bottom - Activities are grouped first by the top side of the board then by the bottom side of the board. Bottom Top - Activities are grouped first by the bottom side of the board then by the top side of the board.
Type - Specifies that activities are grouped by either Part Number or Reference designator for color coding. All Items on one Activity - Creates a single activity with all assigned parts listed. Max Items per Activity - Facilitates large numbers of items (for example, groups of like part numbers or references based on the grouping method) by setting the maximum quantity of items per activity. The smaller the number, the more activities are created. As the number increases, activities are created automatically. (The number of activities created depends on the total number of parts assigned to this operation divided by the Max Items per Activity setting.)
|
Sorting | Side - (electronics) Sorts activities by the selected side of the board for color coding:
Mixed - Activities are sorted by both the top and bottom sides of the board. Top Bottom - Activities are sorted first by the top side of the board then by the bottom side of the board. Bottom Top - Activities are sorted first by the bottom side of the board then by the top side of the board.
Region - Auto-generates activities based on either the whole board/panel or by dividing the whole board/panel into a customer-defined number of regions using a custom window size. Entire Board/Panel - Sorts activities for the entire board or panel. Custom Window Size - Sorts activities based on a custom window size you specify using X-axis and Y-axis coordinates. For complex PCBs, using a custom window size and serpentine pattern helps focus operator attention on specific areas of a PCB. You can also specify the Start Corner and Direction in which activities are sorted. Us the Adjust Independently check box if you want to adjust the X and Y axes measurements independently of each other.
Sort - Specifies the sorting order for the color-coded parts listed for each activity:
Alphanumeric - Footprint Name - Sorts parts alphabetically by footprint name. Alphanumeric - Part Number - Sorts parts alphabetically by part number. BOM Line Item - Sorts parts by BOM line items. Customer Part Number - Sorts parts by customer part numbers. Footprint Size - Sorts parts by the size of the footprint. Manual - Allows you to sort parts manually. Manufacturer Part Number - Sorts parts by manufacturer part number. Polarity - Sorts parts by polarity: positive (+) and negative (−). Quantity - Sorts parts by quantity. References - Sorts parts by reference designator. Socket - Sorts parts by socket type. X - Sorts parts by X-axis location. XY - Sorts parts by X-axis location, then Y-axis location. Y - Sorts parts by Y-axis location.
Use the ASC (Ascending) and DSC (Descending) buttons under Sorting to select the sort order for the parts listed for each activity. Select More Sort Options (...) to the right of the Sort drop-down to display two additional levels of sorting options. (These options also have ASC and DSC sort order options.)
