What the data for this category looks like
This category's data comes from client-provided BOMs, Gerber files, component coordinates, plus real-time data from MES systems, placement machines, SPI/AOI inspection equipment, and reflow ovens. Daily documents include BOM and coordinate files, line change lists, stencil and furnace temperature records, first article confirmation reports, SPI/AOI inspection reports, maintenance records, and traceability labels. Data is updated in real time per work order and each line change. Fields include part numbers, reference designators, component batches, furnace temperature parameters, inspection results, and more. Coordinate data uses millimeters as its unit, and temperature parameters use degrees Celsius.
What constraints these characteristics impose on the HTTP Interfaces and External Systems link
Data for this category comes from multiple sources and is updated in real time. This requires HTTP interfaces to support high-frequency requests to match the synchronization rhythm of each work order and line change, to avoid using outdated component batch or furnace temperature data. Multiple types of business documents require interfaces to support parameter transfer with different fields. Business identifiers such as line change batches and work order numbers must be carried via variables to enable accurate data matching. At the same time, severe errors such as wrong components and solder joint failures require interfaces to carry complete verification parameters, to avoid invalid requests triggering abnormalities in the production process.
How to set the configuration
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
| Request header configuration | Carry an application key in Bearer format, using the value Bearer sk-xxxx | Complies with the application interface identity verification requirements of FastGPT v4.17.0, and ensures interface access security |
| Variable transfer configuration | Carry business fields such as line change batches, work order IDs, and component part numbers | Meets the accurate data matching requirements of multiple business documents for this category, and avoids calling irrelevant maintenance records |
| Response data processing | Extract core fields including inspection items, maintenance solutions, and fault causes | Filters redundant data, and adapts to the quick query scenario of SMT equipment inspection |
| Single request timeout | 30-60 seconds | Adapts to the acquisition and processing rhythm of real-time equipment data, and avoids blocking the production process for extended periods |
| Context window configuration | Retain the previous 3 rounds of conversation context | Matches the continuous troubleshooting needs of maintenance Q&A, and reduces repeated questions |
Three common mistakes
- An interface call returns a 401 Unauthorized error. The cause is failure to correctly configure the identity verification parameters in the request header, or use of an expired application key.
- The maintenance solution returned by the interface does not match the current work order's equipment. The cause is failure to pass business identifiers such as work order and line change batch via variables, leading the system to call outdated or irrelevant document data.
- The published application fails to receive a response from the interface or times out. The cause is failure to set a reasonable request timeout, or the interface request frequency exceeding the interface's current limiting rules.
How to confirm the configuration is correct
- Call the interface with correct identity verification parameters, and verify that the return status code is 200.
- Pass a test line change batch in the variables, and check whether the maintenance solution returned by the interface matches the maintenance requirements of the corresponding component.
- Initiate 10 consecutive high-frequency requests, and confirm that the interface does not experience frequent timeouts or current limiting errors.
- Check the core data fields returned by the interface, and confirm that they include business required information such as inspection items and fault causes.
