Shop Floor Configuration Defect codes Maintenance  Version MES 15.79 Revision G1        

 

Introduction

42Q’s powerful data collection system collects critical information from a plant’s shop floor, utilizing shop floor data collector, an intuitive tool developed by 42Q’s experienced manufacturing team. The aggregate information is stored in a cloud database, and available to MESWeb, where quality reports are generated. The 42Q system uses manual and automated barcode scanning to collect data for a product line or plant. Thus, 42Q plays an important role in maintaining unit histories and directing product movement on the manufacturing floor. The current version of 42Q includes configuration capabilities, which provide access to all sub-modules pages and their functionalities (view, add, edit, print/generate output files). 

 

 

Defect Codes Maintenance

Defect and Repair Codes are maintained through Defect Codes Maintenance from the Shop Floor Configuration Maintenance module.

This module allows defects found after a component is manufactured to be recorded. According to the number of records, the operator will be able to identify a defect to a specific component and reference that defect in the future.

 

To access Defect Codes Maintenance, navigate to Shop Floor Control > Configuration > Shop Floor Configuration > Defect Codes

Note: A user only has access to the modules assigned to his/her profile.

 

 

List Defect Codes

To list Defect Codes, click on Defect Codes Maintenance in the Shop Floor Configuration menu.

The list of defect codes is displayed:

 

Figure 1: Defect Code List

 

The user is able to Add, Import, Print/Export, Edit and Delete Defect Codes.

 

• Defect Codes beginning with "B" are displayed in blue.
  • These codes are known as Process Indicator defects. Process Indicator codes do NOT negatively affect process yield. A process indicator is only used to document a marginal attribute to indicate that it was noted, reviewed and found to be acceptable by the reviewer. Documentation of process indicators provides a measure of the frequency of marginal attributes.
• Defect Codes beginning with "K" are displayed in green.
• All other Defect Codes are displayed in black.

 

Note: All defect codes that begin with the letter B are called process indicators. They are unique in that they will not impact yield and they will not trigger a failure in Shop Floor. Any defect code that begins with K is a standard defect code, which will result in a failure and impact the yield. B defect codes are used to indicate the current condition of a process.

 

 

 

Add Defect Code

This functionality adds a defect code in the system.

To add a Defect Code, select the Add button. The Defect Code Form is displayed:

 

Figure 2: Add Defect Code

2. Populate the mandatory fields (indicated in red) to add a Defect Code. If the mandatory fields are not populated, an error message displays.

 

Defect Code: must be four unique characters

As a general rule:

• Defect Codes that begin with “B” represent Process Indicators. For example: B174 Probe Mark. Process Indicator codes do NOT negatively affect process yield. A process indicator is only used to document a marginal attribute to indicate that it was noted, reviewed, and found to be acceptable by the reviewer. Documentation of process indicators provides a measure of the frequency of marginal attributes.

 

• Defect Codes that begin with “K” represent 'Symptom Codes'. For example: K001 BootStrap Failure. Symptom Codes define the symptom of the failure, not an actual defect. Symptom Code defects negatively affect the process yield the same as all other defects.

Defect Codes that begin with “R” represent Repair Codes. For example R001 Replaced Missing Components. Repair Codes are used to indicate specific repair activity for a recorded defect. For example, the Repair Code for the “Missing” defect code may be “Replaced Missing Components”. The four character Repair Code is used in place of “Yes” and/or “No” for defect repair activity.

Defect Description: Intuitive Description of the defect, limited to 30 characters

String 1 and String 2: Editable user-defined fields.

Code Type: Defect Code, Repair Code, or Symptom Code

 

Note: Align the Code Type with the Defect Code formatting discussed above.

 

3. Select Save to add Defect Code, or select Cancel to cancel. The new Defect Code list is now displayed in the defect list.

 

 

Edit Defect Code

This functionality enables the user to edit the available fields to update a Defect Code.

Note: Be aware that modifying Defect Codes will affect the historical defect information for any serial number with the defect recorded. Take care when editing to avoid changing the code description in such a way that it is completely different than the original. It is best to create a new Defect Code in this situation.

 

To edit a defect code, select a defect and click the Edit button. The Defect Code Form page is displayed.

 

Figure 3: Edit Defect Code

 

Make desired updates in the Defect Code Form and click on Save to confirm the updates.
