What This Category’s Data Entails
Data for this category comes from customer-provided Gerber files, drill files, BOM lists, plus factory internal CAM system data, production equipment parameters, bath solution test records, AOI inspection reports, electrical test reports, and laboratory slice reports. Daily documents include engineering production instructions, drilling lamination parameter records, chemical analysis logs, inspection reports, and more.
Data updates occur in real time as production batches progress, after each shift’s work is completed, or via continuous equipment collection. This covers all stages from customer data conversion to finished product inspection.
Constraints Imposed on Deployment and Upgrade
The multi-source heterogeneous data formats, high-frequency update rhythm, and strongly correlated nature of this category bring multiple constraints to the deployment and upgrade phase.
Multi-source data includes non-standard format engineering files, equipment parameters, and inspection reports. This requires deployment to configure access adapters that support multiple data source types. High-frequency real-time updates require the storage layer to have high concurrent write capabilities to avoid data synchronization delays.
The strong correlation between production batch and inspection data requires retaining the historical data association index logic during upgrades. This ensures that complete production information can be retrieved across documents during Q&A. At the same time, errors in production data can lead to entire batch scrap or high-value claims. Deployment must configure permission controls to prevent unauthorized access to sensitive process parameters.
The following configuration and verification steps are written based on FastGPT v4.17.0.
Configuration Settings
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
PG_URL | postgresql://prod_user:secure_pass@db-host:5432/pcb_kb_db?pool_size=20 | Adapts to storage and associated queries for multi-source structured data, meets the demand for high-frequency small-batch data writes |
REDIS_URL | redis://:redis_auth@cache-host:6379/0?maxmemory-policy=allkeys-lru&maxmemory=8000 MB | Caches frequently accessed production parameters and inspection data to reduce database query pressure, adapts to the real-time update rhythm |
STORAGE_S3_ENDPOINT | Configure according to the factory's internal object storage service address | Stores large-volume documents such as Gerber files and slice reports, adapts to multi-type file storage needs |
ROOT_KEY | Generate a dedicated key based on production department permission divisions | Controls access permissions for sensitive production data, prevents unauthorized retrieval of core process parameters |
DB_MAX_LINK | 20 | Matches the database connection pool configuration, limits concurrent connections to avoid resource exhaustion, adapts to high-frequency data updates per shift |
Three Common Configuration Mistakes
- When calling the GPT-4o mini model, any query containing PCB parameters returns a 400 status code. Switching to another model allows normal retrieval of responses. The cause is that the dedicated access key for this model is not configured, or the key permissions do not cover the model's call scope.
- When debugging in the workflow orchestration interface, the code run step does not display. The cause is that the front-end permission configuration for workflow debugging was not enabled during deployment, or the
FE_DOMAINconfiguration value does not match the actual access domain name. - The FLUX plugin is configured with all correct parameters but cannot generate content. The cause is that the temporary file storage permissions required by the plugin were not enabled in the
STORAGE_S3_ENDPOINTconfiguration, or the environment variables relied on by the plugin were not correctly synchronized to the running nodes.
How to Verify Successful Configuration
- Access the domain configured in
FE_DOMAIN, enter the knowledge base management page, and confirm that the imported PCB production-related document list loads normally. - Run a single production data batch synchronization task, check the database connection pool monitoring metrics, and confirm that the connection count does not exceed the
DB_MAX_LINKconfiguration value. - Call the configured model interface, input a test question containing PCB production parameters, and confirm that the returned result includes associated information from the corresponding documents.
- Check the
REDIS_URLcache monitoring, and confirm that frequently accessed production parameter data has been cached normally.
