Meeting the Core Requirements of Reflow Oven Management
A reflow oven is a very busy machine: it must heat and cool PCBs efficiently while controlling many variables at once. In the end, it has to deliver:
- An in-spec thermal profile
- The required production throughput
KIC RPI collects and optimizes both streams of continuous production data, and provides statistics and reports.
Key Functions
- PCB thermal profile charts
- Automatic profile yield evaluation
- Real-time production details
- Number of PCBs produced
- Product name and lot number
- Production date and timestamp
- Reflow oven name
- Full production traceability
- SPC and Cpk charts
- Process defect and yield reports
- Process defect guidance and statistical reports
- Process optimization
- Remote control
- Automatic alarms
- Automatic alarm light tower
Calculation Example
Total defect opportunities
Boards processed × Measurement points × Process windows = Total defect opportunities (2 x 5 x 5 =50)
DPMO (defects per million opportunities)
Defect points ÷ Total defect opportunities × 1,000,000 (4÷50×1,000,000=80,000)
Yield
100 ÷ Boards processed × Failed boards = Failure rate %, 100% – Failure rate % = Yield
