Why we decide profile travel time in different different zone of reflow process / wave soldering process ?

Question

Accepted Answer

Profile travel time is decided in different zones of reflow/wave soldering process to ensure proper heating and cooling for components.

Profile travel time is crucial for achieving proper soldering results.
Different zones in the process have different temperature requirements.
Travel time is adjusted to allow components to heat up and cool down gradually.
Proper profile travel time helps prevent defects like cold joints or overheating.
Examples: Preheat zone requires longer travel time for components to reach desired temperature, while cooling zone needs shorter travel time to prevent overheating.
