One thing to keep in mind here is that the Nordson style oven is made
especially for conformal coatings while the vitronics is not. The airflow
rates and other factors are much different for reflow than for conformal
coating curing. Our ovens fall into two classes:

One style for Reflow and curing (adhesives, solder mask, etc.)

One style for conformal coat curing.


>I have used a Nordson oven (ETS reflow oven) on 1753 (a thicker version of
>1765) successfully at a previous employer. Cure time was a minimum of 1
>minute (sometimes less) for 2 mil coating. This worked as long as relative
>humidity in the plant was over 25%. There was app. 30 seconds between end
>of spray and oven entrance sitting on a conveyor.
