Load and Unload Solder Paste from the Solder Paste Printer#

Overview#

This feature enables the load and unload of solder paste consumable materials on Solder Paste Printer machines, triggered by Fuji Nexim equipment events.

Relevant Artifacts#

Name Type Is Mandatory Data Type Description
IoTMetadataDefinition SmartTable Yes Metadata configuration used to enable or bypass the solder handling feature per resource.
IoTFujiNeximHandleSolder DEE Yes Attaches or detaches solder paste material from the target consumable feeder on a specified MES resource.
/IoT/FUJI/SolderPasteFeederType/ Config Yes Determines the target consumable feeder.

How It Works#

When a LOADSOLDER or UNLOADSOLDER event is received from the Fuji Nexim equipment, the following steps are executed:

Area Feature Checks#

  • Resolves the MES Sub-Resource Name using the pattern: FUJI_LineNameMachineName_{EquipmentLineName}_{EquipmentMachineName}.

Resource Feature Checks#

  • Checks whether the UseFujiToHandleSolder feature is enabled for the resolved MES Resource in the IoTMetadataDefinition Smart Table.

MES Operations#

If the feature is enabled, the Automation Controller calls the DEE IoTFujiNeximHandleSolder, which performs the following:

  • Validates the solder material identified by SolderID and confirms its Product matches SolderName.
  • Determines the target consumable feeder using the configuration key /IoT/FUJI/SolderPasteFeederType/.

  • Performs the operation based on the Operation input:

    Load:

    • If the material is already attached to the correct feeder on the correct resource, no action is performed.
    • If the material is attached to a different feeder, it is detached first.
    • If the target feeder already has a different material attached, it is detached first.
    • The solder material is then attached to the target feeder.
    • If the material does not exist in MES, an error is thrown.

    Unload:

    • If the material is not attached, no action is performed.
    • If the target feeder does not belong to the resource, no action is performed.
    • Otherwise, the solder material is detached from the target feeder.

  • Sends a LOADSOLDER_ACK or UNLOADSOLDER_ACK message back to the equipment with:

    • A result (0 = Ok, 1 = NOk) for the operation.

Error Handling If any step fails during the DEE operation (e.g. material not found, feeder not found, configuration missing), the operation is considered failed and an error is returned to the equipment.

Bypass Condition If UseFujiToHandleSolder is set to False or is not defined in IoTMetadataDefinition, the DEE call is bypassed entirely and no MES operation is performed.

Assumptions#

The IoTMetadataDefinition Smart Table must be configured with the following entry for each station:

Resource ResourceType Area Name Value
