What this category of data looks like
This category of data comes from engineering, production, quality control, and laboratory roles in printed circuit board factories. Daily documents include engineering production instructions, Gerber analysis records, drilling and lamination parameters, chemical solution analysis, AOI reports, electrical test reports, and slice analysis reports. Data sources cover customer Gerber/drill tape/BOM, CAM, equipment parameters, bath solution testing, AOI, electrical test, and laboratory data. Update frequency follows per production batch, per shift, or continuous collection. Fields include process parameters, test results, equipment status, and other items. There are no unified fixed units. Fields and units adjust dynamically based on document type.
What constraints these characteristics impose on the forms and interactions link
Since data sources cover multiple roles and multi-system documents, and update frequency varies with production batches and shifts, the forms and interactions link must support associative binding of multi-source fields to avoid duplicate entry of associated data for the same production batch. The field structures of different documents vary widely. The interaction must provide custom field templates to adapt to different types of inspection and maintenance documents such as engineering production instructions and AOI reports. Production data errors can lead to scrapping of entire board batches. The form must add real-time verification logic to trigger alerts for abnormal parameters. Continuously collected equipment status data must support streaming entry to adapt to real-time inspection scenarios.
How to set up the configuration
This document is adapted for FastGPT v4.17.0. The following configurations are based on the forms and interactions module of this version:
| Configuration Item | Recommended Setup | Rationale |
|---|---|---|
formInput | Bind equipment number, inspection time, and production batch fields | Adapt to the standardized entry requirements of PCB manufacturing equipment inspection, ensure data can be associated with the corresponding production link |
userSelect | Preset maintenance team, fault type, and equipment model options | Match the existing operation and maintenance personnel division of labor and PCB equipment classification system in the factory |
| Chunk length | 800–1200 characters | Adapt to the single-page parameter length of PCB manufacturing documents, avoid breaking the integrity of process parameters due to segmentation |
| Reranking | Enabled, take the top 6 results | Optimize Q&A matching accuracy for redundant information from multi-source retrieval, adapt to the short query scenario of factory inspection and maintenance |
| Single search limit | 10 entries | Control the number of retrieval returns, avoid excessive irrelevant data interfering with Q&A results |
| Max context | 6000 token | Accommodate the complete content of engineering parameters for multi-layer PCBs and multiple test reports |
Three common mistakes
- Phenomenon: After enabling the reranking function, the response time of equipment inspection Q&A is significantly prolonged. Cause: The retrieval limit is not adjusted according to the chunk length of PCB documents, causing excessive redundant data to participate in the reranking process.
- Phenomenon: When adding team members, entering the corresponding account prompts that the username is invalid. Cause: The mapping rules for internal factory operation and maintenance accounts are not configured, and only public platform account format matching is supported.
- Phenomenon: When importing Gerber or AOI reports, the page keeps refreshing and the target page cannot be selected. Cause: The parsing adaptation switch for PCB-specific documents is not enabled, and the system cannot recognize the pagination structure of non-general documents.
How to confirm the configuration is complete
- Import a single standard PCB drilling parameter document, check whether the form fields automatically match and bind with the document content.
- Launch a Q&A about abnormal lamination parameters, verify whether the retrieval results cover the equipment parameters and test reports of the corresponding production batch.
- Test the team member addition process, confirm that there is no invalid prompt after entering the corresponding internal factory account.
- Import a multi-page AOI report, confirm that pagination loads normally and the specified target page can be selected.
