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 in 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 an 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

MSD System setting

There are options for MSD Control at the system setting:  

• MSD Expire Warning: Default value is ‘NO’. This option is to define whether to give users the MSD will expire warning message when the load material. ‘Yes’ to send a warning email to users before the MSD Expire Warning Time.
• MSD Expire Warning Time: Default value is empty.

         If the switch ‘MSD Expire Warning’ is on then the configuration item ‘MSD Expire Warning Time’ can be used.

• MSD Expire Stop :If it is checked, all the production lines will check the MSD remaining time when load comp. Else only check the MSD remaining time of those configured in Production Line Settings.When loading material to fuji, request pts to do validation and get the expired time, “MSD Expire Stop”(0/1).

  Figure 23: MSD System setting

MSD Material on Split/Transfer Material

• New label after PTS Split 

          If the MSD material is split then the new MSD material will retain the parent MSD material-related MSD operation history records.

• New label in PTS after change item number 

          If the MSD material is changed part number then the new MSD material will retain the parent MSD material related to MSD operation history records.  

 

 

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 an MSD material is in baking status and the bake time is not completed, then the current material will not be allowed to load.
• If an MSD material is expired, then the material will not be allowed to load.
• If an MSD material is in baking status then its MSD start time will be modified to the current time.
• If an MSD material is in a dry bag or dry cabinet, then its exposed time should not include the time of dry bag or the 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.

 

 

MSD Process for Scanning Board via Fuji System/MES Connector

• The Fuji MSD control configuration will be able to configure based on individual SMT production line

Configuration 1: PTS System Setting →  MSD Expired Stop Set as Yes.

Configuration 2: MES Connector Traceability Configuration → MSD Control option been selected.

Configuration 3: MES Connector Production Line Setting → MSD Control option been selected 

The Configuration 1 will be similar to the main power switch for the entire building. The Configuration 2 will be similar to the main power switch for each apartment. The configuration 3 will be similar to each individual light switch for the apartment. In order to turn the apartment light on, all three switches will need to turn on at the same time. 

• The Fuji system will send out the MSD Material barcode id to the PTS web service for validation via the MESAgent app if the production line MSD control option has been selected. Therefore, the Fuji MSD control was able to be configured based on the production line a long time ago. From MES 15.69 the system has improved the MSD stop with the MSD control rule and the MSD stop will be able to be configured by individual production lines.
