Production

The Parts Traceability System (PTS) is one of the applications within the MES suite of tools. It was developed to meet the demands of customers to provide component level traceability as well as to provide quality controls. This system plays a very important role in automating the production lines and raising productivity as well as enforcing rigorous product quality control. It has been implemented to many plants across the globe. This application and the features it provides continue to evolve, as the changing technologies used for the SMT process equipment tools become more detailed and rich in functionality.  There is and will continue to be a requirement to support the older technology tools. We strive to provide the flexibility to support each of the line types and provide the different and many levels of traceability required for the business.

MSD (Moisture Sensitive Device)

General Notes

This Work Instruction is a basic general training guide and is not meant to teach the process flow for individual plant or department functionality. Individual Sanmina sites may have minor or specific process changes that will be documented at the site level.

 

Overview

The control of moisture-sensitive devices (MSDs) prior to SMT reflow is a critical assembly issue that has a direct impact on final product reliability and customer satisfaction as well as manufacturing costs. The guidelines for storage and handling of MSDs are clearly defined in the joint IPC/JEDEC standard J-STD-033.

At this system, the actions for the MSD materials contain:

• Open MSD package
• Dry Cabinet at 5% RH
• Dry Cabinet at 10% RH
• Dry Bag
• Out Dry Cabinet
• Bake
• End Bake
• Terminate MSD Control
• Load/Unload Material

The system allows users to handle the MSD by the actions, and the actions will change the MSD material status. Following is the MSD Status with Actions:

Seq	Actions	MSD Status after the action
1		Package not opened
2	Open MSD Package	Package Opened(manual)
3	Dry cabinet at 5% RH	Cabinet at 5% RH
4	Dry cabinet at 10% RH	Cabinet at 10% RH
5	Out Dry cabinet	Exposing
6	Bake	Baking
7	End Bake	Exposing
8	Dry bags	Dry Bag
9	Load material	On SMT(Auto)
10	Unload material	Pending
11	Terminate MSD Control	Terminated

Check MSD Status

This module is used to view the status of the MSD material.

 

1. To access the Check MSD Status page, navigate to Production --> '''100% Traceability'''-->MSD (Moisture Sensitive Device) -> Check MSD Status.

2. Enter the material barcode.

3. If the material is valid MSD material, the detailed information will display.

Figure 3: Check MSD Status

• If the operator enters a non-existent material barcode, the system will display the following message: "Material barcode not found".
• If the operator enters a non-MSD material barcode, the system will display the following message: "This material isn't MSD material".
• The operator can enter any MSD material which is in any status and related items. For example MSD level, floor life, current status and process time etc. can be all displayed.
• The pie chart located on the right displays the MSD expose time and the MSD remain time. It is a very easy and clear way for users to understand current material MSD status.

 

Pending MSD Handling

This module is used to handle pending/unfinished MSD material, which is in pending status or already expired.

Key in material barcode, system will check for MSD spend time.

1. To access the Unfinished MSD Handling page, navigate to Production -> 100% Traceability ->'MSD (Moisture Sensitive Device) ->' Pending MSD Handling.

2. Enter a MSD material barcode into the Material Barcode text box.

3. After entering the Material Barcode, click anywhere on the web page.  

Figure 4: Pending MSD Handling

 

4. MSD material information will be shown in the MSD Information box.

5. Select handling method from Process Status. Currently, provided the following four methods:

• Dry bags: to handle the MSD material which still not expired or in pending status
• Dry cabinet at 5%RH: it can dry unexpired or pending MSD material. It can also be used for large MSD material. 
• Dry cabinet at 10%RH: it can dry unexpired or pending MSD material. It can also be used for large MSD material.
• Out dry cabinet: If users submit the ‘Out Dry Cabinet’ action, the MSD status will be changed from ‘Dry cabinet at 5% RH’ or ‘Dry cabinet at 10% RH’ to ‘Exposing’ status.
• Bake: used to bake the expired MSD material.
• End Bake: If users submit the ‘End Bake’ action, the MSD status will be changed from ‘Baking’ to ‘Exposing’ status.
• Select an action and select Send to handle this MSD material.

 

Note: For any expired material, the user must select Bake Action.

 

Figure 5: Pending MSD Handling- Bake

 

If the user selects Bake material, the following options will be available:

• Bake Duration (hours): how long the MSD Material will be baked. (It can be changed.)
• Bake Time (h: m): system default current time. (It cannot change.)
• Customize Bake Information: only for special plants to customize the temperature and humidity.

Note: If users choose to Customize Back, they must input comments at the Comment edit field.

 For details about how to customize bake information, please review Customize Bake Time function.

• Standard Bake Information: if no special temperature and humidity, select the standard one from this box as stated.
• Select Send to Bake the MSD material.

 

Notes:

• If the operator enters a non-existent material barcode, the system will display the following warning message: "Material barcode not found".
• If the operator enters a non-MSD material barcode the system will display the following warning message: "This material is not MSD material".
• If the operator enters an MSD material and chooses process status Dry Bags then selects Send,the current MSD material will be put into dry bags for traceability.
• If the operator enters an MSD material and chooses process status Dry cabinet 5%RH or Dry cabinet 10%RH and selects Send, the current MSD material will be put into a dry cabinet for traceability.
• If a MSD material is in loading status for scanning, then the MSD material cannot be processed by this function.
• If a MSD material is already terminated in MSD control, then it cannot be processed by this function.

MSD Process for Loading Material

• If a new MSD material is loaded for the first time, then it will be treated as if the operator were opening the package immediately. The MSD level (user defined when printing label) and humidity (user defined in system setting) and temperature (user defined in system setting) must match at least one MSD floor life policy data record.
• If a MSD material is in baking status and the bake time is not completed, then the current material will not be allowed to load.
• If a MSD material is expired, then the material will not be allowed to load.
• If a MSD material is in baking status then its MSD start time will be modified to the current time.
• If a MSD material is in dry bag or dry cabinet, then its exposed time should not include time of dry bag or time of dry cabinet.

 

MSD Process for Unloading Material

• If a MSD material is unloaded, then its MSD status will be changed from open package to pending.
• If a MSD material is unloaded and its remaining quantity is zero, then its MSD status will be changed to a special status which stands for "quantity of current material is zero."

 

MSD Process for Scanning Board

• If one of all MSD materials for current workstation is MSD expired, then the current workstation scanning board is not allowed and corresponding error message is displayed.
• If current board is already MSD expired, then the current scanning board is not allowed and corresponding error message is displayed.
