  1. Introduction

Solder Paste is an application able to help plants to control the storage and use of Solder Paste materials to avoid human errors and lapses. The project has the standard process and creates error-proofing of Solder Paste control, to ensure plants comply with the varying Solder Paste part number’s storage life and use life limits, and ensuring a constant environment, to stop out-of-specs solder paste from being used in production.

This System provides a standard process that includes the following steps:

  1. Refrigeration In
  2. Refrigeration Out
  3. Thaw Start
  4. Thaw End
  5. Stirring Solder-Paste (Not support temporarily)
  6. Open Jar
  7. Load Solder-Paste
  8. Unload Solder-Paste
  9. Scan board
  10. Solder-Paste Scrap

Also supplies reports forSolder Paste status view and Solder Paste tracking.

  1. Configuration

Before starting theSolder Paste process, there are some system settings and material control to configure first;

The following are the detailed configurations:

  • System Setting: Set Solder On Board setting.
  • Material Labeling: Generate/print solder paste barcode/PN
  • Solder Paste Material Control: Set the control parameters of the solder paste material.
  1. System Setting

There is a switch in the System Setting function called ‘Solder On Board’ for users to set control of the Solder Paste material or not. To set the Solder On Board, follow the steps below:

  1. Select Administration --> Traceability Administration --> System Setting.
  2. Select the MSD Control tab.
  3. Set the value of Solder On Board.
  4. Click the Update button.

Figure 1: System Setting - Solder On Board

 

 

  • If the switch ‘Solder On Board’ is opened (Yes) then all solder paste related functions (steps) can be used normally ( the pages show, and can edit).
  • If the switch ‘Solder On Board’ is closed (No) then all solder paste related functions (steps) can not be used ( the pages show, but can not edit).

For the solder paste material control process, the value of Solder On Board must be ‘Yes’.

  1. Material labeling

Material Labeling is the function of printing material barcodes.

Note: There is one interface to import materials into the42Q Solder Paste database for some plants that do not use this material labeling function to generate material barcodes.

  1. Select Shop Floor Control--> Incoming Traceability --> Material Labeling.
  2. Select theReceipt Traveler No./ Number, press Enter key.
  3. Set the values of the material.
  4. Click the Submit button.
  5. The material barcode will be generated and the label printed successfully.

  1. Solder Paste Material Control

Solder Paste Material Control is the function that users can set or configure the Solder Paste material, such as Storage Temperature,Min storage time, ambient humidity, and floor life, etc.

  1. Select Shop Floor Control--> Production Control --> Solder Paste Material Control.
  2. Select theAdd/Edit/Delete to set the solder paste material control setting.

  • Solder Paste MPN: The manufacturer Part Number of Solder Paste material. It can not be blank.

There are four levels ofSolder Paste control.

  • N/A
  • Product Part Number
  • Family ID
  • Tag

For the same MPN (Manufacturer Part Number), the priority of the Solder Paste material control is; Production part number, tag, family ID, then N/A. That means the system will first use the Product/BOM part number level Solder Paste material control , if it is blank, then use the Tag level Solder Paste material control, then use Family ID level solder paste material control, and to use the N/A level Solder Paste material control the last.

Following is the description of the priority.

Priority Type Description Comment
Pri(1) Product Part Number The product Part Number is the BOM Part Number. This option means all the materials from this manufacturer part number (MPN) and in the Product/BOM part number use this solder paste material control setting.
Pri(2) Tag This option means all the materials from this manufacturer part number(MPN) and with this tag use this solder paste material control setting. Tag must have been defined at MDS.
Pri(3) Family ID This option means all the materials from this manufacturer part number(MPN) and with this Family use this solder paste material control setting. Family ID must have been defined at MDS.

Users need to define the Conduit and Conduit_ShopFloorID

At server information module.

Pri(4) N/A This option means all the materials from this manufacturer Part Number(MPN) use this solder paste material control configuration/setting.

If users select the radio button ‘Tag’, then there will be a text field item named ‘Tag’ and the values will show in a dropdown list. Note: The Tag is maintained at Part Maintenance in SFDC configuration. Users need to define the Conduit and Conduit_ShopFloorID at the Server information module. Figure 6: Server information example

  • Optimal Storage Temp: The optimal storage temperature of the Solder Paste material.
  • Storage Temp Dev(+/- ): Storage temperature deviation. This is the deviation temperature that can be upper or lower than the optimal storage temperature. If the real storage temperature for the Solder Paste material is not between (Optimal Storage Temp - Storage Temp Dev) and (Optimal Storage Temp + Storage Temp Dev) , the system will pop up error information.

 

  • Min Storage Time(Hr): The min time of the storage for the solder paste material. If the storage time is less than the mini-storage time, the system will pop up error information for it.
  • Min Thaw Time(Hr per KG): The min time of the thaw for the solder paste material. If the thaw time is less than the mini thaw time, the system will pop up an error information for it.
  • Max Storage End Thaw End Time(Hr): This time is the max time of all the process for the solder paste material. From refrigeration in,refrigeration out,thaw start,thaw end,open Jar, load material till to scan board.
  • Max Allowed Thaw Cycle(Count): The max thaw times for the solder paste material. For example: if max allowed thaw cycle set to 2, that means this solder paste material can have 2 thaw processes. If more than 2, the system will pop up error information.
  • Enforce Stirring: Not supported yet.
  • Min Stirring Time(s): Not supported yet.
  • Max Stirring Time(S): Not supported yet.
  • Stencil Life(Hr): This time is the Solder Paste material that stays at the stencil. Once the Solder Paste material is loaded on the production line workstation, the system will start to count the time.
  • Stencil Idle Time(Hr:): Not supported yet.
  • Stencil Idle Max Tim(Hr): This time is to control the time between scanning two boards. The system will start to count time once the first board is scanned.
  • Recycle Life(Hr):// Not supported yet.
  • Floor Life(Hr): The floor life of the Solder Paste material. The system will start to count the time when the material was opened (open jar).
  • Shelf Life(Day): The shelf life of the Solder Paste material. The system will start to count the time when the material label generated (The create time of the material barcode).
  • Ambient Humidity Low Limit(%): The lowest ambient humidity of the solder paste material.
  • Ambient Humidity High Limit(%): The highest ambient humidity of the solder paste material.
  • Ambient Temp Low Limit(%): The lowest ambient temperature of the solder paste material.
  • Ambient Temp High Limit(%): The highest ambient temperature of the solder paste material.
