Dwell Time
- Define dwell time.
- What types of defects are caused when your dwell times are too long?
- What types of defects are caused when your dwell times are too brief?
- How does a faster conveyor speed affect your dwell time?
- How does a deeper immersion depth affect your dwell time?
- Why do you need to establish parallelism and control immersion depth before you
identify the best dwell time for a particular board type and/or verify dwell time
repeatability?
- Describe how to determine the optimal dwell time by board type.
- Why does verification of your optimal dwell time prior to your board type changeovers
and at the beginning of every shift eliminate improper dwell times as a cause of
board defects? Why is verification necessary every board changeover and every shift
rather than weekly? Why do we consider this the most important question of this
dwell time section?
