Supplier and Process Quality Audit for Semiconductor Packaging and Testing: Tool Calling and Plugins

Data for this category is primarily collected from wafer test maps, Manufacturing Execution System (MES), bonding and molding equipment, ATE testers

What Data for This Category Looks Like

Data for this category is primarily collected from wafer test maps, Manufacturing Execution System (MES), bonding and molding equipment, ATE testers, X-ray/SAM inspection equipment, and customer specification documents. Daily maintained documents include packaging process cards, bonding and molding parameter tables, incoming wafer maps, test program version files, yield reports, and failure analysis reports. Data update frequencies cover per batch of materials, per chip test, and daily summary. Fields include chip batch number, test bin distribution, equipment parameter thresholds, and more. Adaptation to multi-source heterogeneous data structures is required.

How These Characteristics Create Constraints for Tool Calling and Plugins

Multi-source heterogeneous data sources require tool calling plugins to support integration with industrial device APIs, MES interfaces, and document parsing tools, adapting to different communication protocols and data formats. The high-frequency update frequency requires that tool calling context length be strictly limited, to avoid model context overflow caused by excessive data volume. Diverse document types and fields require tool parameters to cover specific fields such as chip batch number, test program version, and yield indicators, to ensure accurate extraction of required information during audits. Additionally, support for alignment operations between wafer maps and physical batches is needed, to match the association between incoming material information and test results.

Configuration Settings

This configuration applies to FastGPT v4.17.0.

Configuration ItemRecommended ValueRationale
Maximum Context Length8000–12000 tokenSingle batch of packaging and testing data has a large volume, to avoid truncation caused by exceeding the model's bearing capacity
Tool Calling Retry Count2–3 timesIndustrial device calls may experience temporary network fluctuations, reducing invalid process interruptions
Tool Calling Timeout30–60 secondsEquipment such as bonding machines and ATE testers require a certain amount of time to respond, and excessive time will block the overall audit process
Workflow/API tool selectionautoAutomatically select the tool suitable for the current task, no need to manually specify the calling object
Workflow/API function-call configurationstrictStrictly verify the parameter format of tool calls to ensure compliance with the field requirements of packaging and testing documents
Plugin Data Format ValidationEnabledAlign the field specifications of structured data such as incoming wafer maps and test program versions

Three Common Misconfigurations

  • Context overflow error occurs during tool calling, with logs showing content length over limit. The cause is failure to limit maximum context length; data such as yield reports and failure analysis reports for a single batch of packaging and testing has a large volume, exceeding the model's bearing capacity.
  • Tool call parsing fails, returning Tool call Parser related errors. The cause is that the content returned by the inference model is wrapped in think tags and placed in the content field, which does not meet the preset tool call format requirements.
  • Forwarding error occurs after configuring the MCP server, returning a long error code. The cause is that the aiproxy key forwarding rules are not configured correctly, causing the model request to fail to be forwarded normally to the target service.

How to Verify Proper Configuration

  • Submit simulated data for a single batch of packaging and testing, check whether the tool call can automatically trigger the corresponding data extraction or device query action.
  • View the tool call log, confirm that the parameter format meets the preset field requirements of the packaging and testing documents, and there are no parsing errors.
  • Test the timeout and retry logic of tool calls, simulate temporary network fluctuations, and check whether the retry can be completed according to the configuration and valid results are returned.
  • Compare the configured context length with the actual size of a single batch of data, confirm that no out-of-limit situation occurs.
