Nozzle Condition Audit Worksheet: 5-Minute Checklist for Your SMT Line
Nozzle Condition Audit Worksheet
Use this 5-minute worksheet to assess your current Nozzle maintenance effectiveness. Fill in your data below and use the comparison to identify gaps in your maintenance routine.
Step 1: Replacement Record Check
- Are replacements date-driven (fixed schedule) or condition-driven (based on vacuum measurement)?
- Date of last Nozzle replacement on Line 1:
- Date of last Nozzle replacement on Line 2:
Step 2: Vacuum Test
| Nozzle # | Used For | Vacuum (kPa) | Threshold (85% of spec) | PASS/FAIL |
|---|---|---|---|---|
| 1 | Heaviest component | |||
| 2 | Most frequent component | |||
| 3 | Rarely used Nozzle |
Step 3: CPH Comparison
| Metric | Value (CPH) |
|---|---|
| CPH 7 days after last cleaning | |
| CPH 7 days before last cleaning | |
| Difference |
Interpretation Guide
| Condition | Action |
|---|---|
| CPH difference > 3% | Your cleaning interval may be too long. Shorten it and re-measure. |
| Vacuum below 85% of spec | Clean immediately and re-test. If still low, replace the Nozzle. |
| Replacement is date-driven (no vacuum data) | Consider switching to condition-driven maintenance using vacuum measurement as the trigger. |
