Where electronic components plants get stuck
Problems that come up repeatedly in implementation discussions.
Field issueMachine logs and inspection data are separated
SMT placement logs stay with the machine, X-ray and AOI verdicts with the inspection system. Reading placement history and inspection result together for one board means manual cross-referencing.
Field issueMaterial lots do not connect to finished goods
Without a record of which reel went into which lot, a confirmed material problem cannot be narrowed to a recall scope.
Field issueMis-issue depends on human checking
Similar parts are everywhere and visual verification has limits. The later a mis-issue is found, the more it costs.
Field issueCustomer quality requests are answered by hand
Formats differ per customer, so the pack is rebuilt each time. Without the raw data in one place that work never shrinks.
What gets connected
Machine signals and floor entry combined into history.
| What is connected | How it is collected | What it produces |
|---|
| SMT machine log | Machine output file or protocol | Placement history, per-machine running state |
| X-ray / AOI verdict | Inspection machine integration | Defect type and location, pass/fail history |
| Material lot | Barcode / QR scan | Reel and lot bound to finished goods |
| Reflow profile | Machine log | Process condition history |
| Work order and BOM | MES / ERP integration | Issue verification, mis-issue blocking |
Build sequence
Nothing is converted all at once. High-impact areas are built and verified first.
- STEP 01
Settle the material identification scheme
Decide first how reels and lots are identified. With identification in place everything downstream can be traced; without it, no amount of collected data joins up.
- STEP 02
Introduce issue verification
Compare the work order BOM against what is actually scanned and stop the operation on a mismatch. Mis-issue is blocked at occurrence rather than discovered afterwards.
- STEP 03
Collect machine and inspection data
Gather SMT logs and inspection verdicts and attach them to the lot.
- STEP 04
Build the quality history view
Organise query conditions and output shapes so history can be produced in the format customers ask for.
Quick AnswersElectronic components — frequently asked
Questions that come up on electronic components floors.
SMT log formats differ by vendor. Is that a problem?
They are standardised in the collection layer. Log files, protocol reads and contact signals are each taken in and organised into one structure, so upstream systems never see the difference.
How does mis-issue blocking work?
Scanned material is compared against the BOM defined on the work order. A mismatch raises a warning and stops the operation; how hard it stops is set to match the floor.
Do we have to retain X-ray images?
Verdict and location usually satisfy traceability requirements. Image retention is decided together with storage capacity and retention period.
Customers each want a different format. Can that be handled?
With the raw data in one place, output formats are a query concern. More formats does not mean recollecting data.
Can we see a semiconductor parts case study?
Detailed cases in that sector are not published at customer request. Scope and approach are discussed using structurally similar cases during consultation.
