What the data for this category looks like
The data sources for processes and standards in SMT placement and electronic assembly cover BOMs, Gerber files, coordinate files provided by customers, as well as MES systems, solder paste and component batch ledgers, placement machines, SPI/AOI testing equipment, reflow oven temperature records, etc. Data update frequency is adjusted in real time with work orders and line change operations, and includes documents such as BOM lists, line change tables, stencil parameters, furnace temperature curves, first article confirmation reports, defect repair records, and traceability labels. Fields include part numbers, reference designators, component models, soldering temperatures, placement coordinates, etc., with units including millimeters, degrees Celsius, batch numbers, etc. Unlike the PCB manufacturing category, data for this category is generated around the component placement process and does not include content related to substrate circuit manufacturing.
What constraints do these characteristics impose on the HTTP Interfaces and External Systems link
Since data sources are scattered and updated in real time, interfaces must support synchronizing documents in different formats from multiple systems, while adapting to high-frequency work order-level data updates. Document types include structured CSV files, report files, and real-time logs, so interfaces must be compatible with multiple data parsing formats. Fields are highly specialized, so interface parameters must match SMT-specific business fields to avoid deviation in retrieval scope. Errors may trigger mass production issues, so interfaces must have retry and verification mechanisms to ensure the accuracy of data transmission.
How to set the configuration
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
| Authentication Method | Bearer {custom API key} | Complies with FastGPT v4.17.0 interface authentication standards |
| Input Variables | Includes work order ID, component batch number, furnace temperature range | Matches real-time process data for SMT work orders |
| Single Search Limit | Top 3 entries | Avoid returning too much data that causes system overload |
| Return Data Format | JSON structure, including specification number, applicable equipment model | Adapts to data parsing for EMS factory MES systems |
| Request Timeout | 600 seconds | Adapts to delays in real-time pulling of furnace temperature and SPI reports |
| Maximum Context Length | 1000–1500 characters | Adapts to field length of BOM files |
Three common misconfigurations
- Phenomenon: When calling the create file collection interface, local CSV format BOM files cannot be uploaded. Cause: The form format for file upload is not correctly configured in the request parameters, or the field requirements for SMT placement documents are not matched.
- Phenomenon: When calling the interface with a custom authentication token, a permission denied or billing prompt is returned. Cause: The token is not bound to the access permission of the corresponding SMT process knowledge base, or the token configuration format does not meet FastGPT requirements.
- Phenomenon: The process specification entries returned by the interface do not match the current work order. Cause: The correct work order ID or component batch number is not passed in
variables, resulting in the retrieval scope covering expired line change data.
How to confirm the configuration is correct
- Use a test work order ID to initiate an interface request, check whether the returned
responseDataincludes the line change table content corresponding to that work order. - Upload a test BOM CSV file, confirm that the interface can correctly parse the part number and reference designator fields in the file.
- Call the authentication interface, use the configured authentication method, confirm that the returned status code is 200 and there are no permission error prompts.
- Simulate real-time updated component batch data, initiate a retrieval request, confirm that the returned results update as the batch number changes.
