Quality control by method, metric, and defect record.
FPY, PPM, and OTD tracked per program, with CAPA and 8D opened from traceable defect records.
- FPY
- per operation

QMS scope
Documented control plans per program.
FMEA on new processes and on every PCBA at first-article release.
CAPA and 8D triggered from MES defect records.
RMA cycle with documented triage, analysis and closure steps.
Internal audits per program area on a fixed schedule.
Operational metrics we report
| First-Pass Yield (FPY) | Per operation, per line, per shift. |
|---|---|
| Defect PPM at shipment | Reported per shipment and per program. |
| On-Time Delivery (OTD) | Against confirmed dates, not against requested dates. |
| Cycle time | Per program; baseline + monthly delta. |
| Rework rate | Tracked separately by defect category. |
CAPA and 8D — how a defect becomes a record
- Defect captured in MES with operator, station, lot and serial.
- Triage by quality engineering — containment first, root cause next.
- 8D opened for systemic or customer-impacting defects.
- CAPA proposed and reviewed; effectiveness validated after implementation.
- Closure recorded in MES with effectiveness data.
RMA cycle — what to expect when something goes wrong
Customer raises RMA via sales@dannie.cc with serials and failure description.
RMA registration and triage follow the escalation flow defined for the program.
Failed unit shipped back per agreed Incoterms.
Failure analysis report (visual, X-Ray, electrical) is issued in the agreed reporting window for the program.
8D issued for recurring or systemic causes; CAPA proposed in the same report.
Traceability model
Component lot to board serial.
Board serial to assembly batch.
Assembly batch to shipping unit.
SPI, AOI, X-Ray, ICT and FCT results stored against the serial.
Audit support
Customer audits supported with one-week scheduling notice.
Pre-audit documentation pack available on request.
Witness builds supported for first article and revision changes.
Third-party audits (customer-nominated) supported with documented escort.
Quality classes we run
| IPC-A-610 Class 2 | Standard for industrial / consumer / commercial PCBA. |
|---|---|
| IPC-A-610 Class 3 | On request — high-reliability programs (medical, aerospace context). |
| IPC/WHMA-A-620 Class 2 / 3 | Standard / on request for cable harnesses. |
| IPC-A-600 | Bare PCB acceptance per Class 2, Class 3 on request. |
Reports we provide on request
AOI / X-Ray / ICT / FCT result samples.
FPY and Pareto reports.
8D reports for closed defects.
First-Article Inspection (FAI) reports.
