What the Data for This Category Looks Like
PCB manufacturing quality traceability data sources include Gerber files, drill files, and BOMs provided by customers, plus outputs from CAM systems, production equipment parameters, bath solution test records, AOI inspection reports, electrical testing reports, and section analysis reports. Data updates are triggered per production batch, shift, or via continuous collection. Daily documents include engineering production instructions, drilling and lamination parameters, and chemical analysis ledgers. Fields include hole position coordinates, copper thickness values, inspection batch numbers, and must match equipment and process parameters from production links.
How These Characteristics Create Constraints for Tool Calling and Plugins
PCB manufacturing data is scattered and has inconsistent formats. Tool calling must adapt to parsing multi-source heterogeneous data, and plugins are required to natively read Gerber and CAM files. Data updates have batch-based and high-frequency characteristics. Tool calling must support batch task scheduling triggered by production batches to avoid mixing data across batches. Daily document fields vary significantly. Tool parameters must support custom field mapping, and fixed field templates cannot be relied upon. Errors in quality problem traceability carry severe consequences. Tool calling must add an exception verification link, trigger an alarm when missing parameters or format errors are detected, and prevent incorrect data from entering the analysis process.
Configuration Settings
This configuration is based on FastGPT v4.17.0.
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Workflow/API tool selection | Fixed call of a specified tool set | Matches the fixed tool chain for PCB manufacturing quality traceability, avoids confusion in tool calls |
| Workflow/API function-call configuration | Enable parameter format verification | Ensures that the input parameters of tool calls meet the business format requirements of PCB manufacturing |
| Global variable passing | Enable workflow variable injection | Meets the need to pass permission tokens, and adapts to identity verification across tools |
| Multi-source data parsing plugin | Bind Gerber and AOI report parsing plugins | Adapts to the unique engineering document formats of PCB manufacturing, improves data reading accuracy |
| Exception verification rules | Calibrate based on actual measurements | Adapts to process parameter fluctuations across different batches, avoids misjudgment of normal production data |
| Single call data limit | 800–1200 inspection records | Controls the load of single-batch data processing, avoids tool call timeouts |
Three Common Misconfigurations
- Phenomenon: Unable to obtain workflow global variables when calling an MCP tool, with empty parameter fields in the response. Cause: The workflow variable binding configuration is not enabled, and global variables are not mapped to the input parameters of the tool call.
- Phenomenon: Connection timeout occurs when calling a locally deployed MCP tool, and local production data cannot be obtained. Cause: Local network access permissions for tool calls are not configured, and access rules for the corresponding port are not opened.
- Phenomenon: No relevant content is returned when querying a cross-team knowledge base. Cause: Access permissions for the cross-team knowledge base are not configured, and the tool call does not carry the correct team identity token.
How to Verify Correct Configuration
- Trigger a simulated production batch tool call, check whether the tool is triggered according to the production batch, and whether the global variable token is correctly passed to the tool parameters.
- Upload Gerber files and AOI inspection reports, check whether the parsing plugin can correctly extract core fields such as hole positions and copper thickness, with no parsing failure errors.
- Configure cross-team knowledge base access permissions, initiate a cross-team query, and check whether matching document content can be returned normally.
- Simulate a scenario where the single-batch data volume exceeds the limit, check whether the tool triggers load control, and no timeout or abnormal exit occurs.
