I would like to check our Wave Soldering conditions meet to snoa292 document (Recommended Soldering Profiles) or not.
Our Wave Soldering conditions are below.
Preheat temperature : 120 to 140 degrees C
Preheating time : 60 to 90s
Peak Soldering Temperature : 250 degrees C
Peak Soldering Time : 6s
I checked snoa292 document (Recommended Soldering Profiles).
This document has "Ramp Up °C/sec" and "ΔT".
I think these conditions are preheating.
Regarding preheating, I couldn't judge that our conditions meet to snoa292.
If there are temperature and time for preheat, could you share them?
