Hey Peter, it depends on how many board types and what sizes/complexity
your boards are. Say if you have a large variety of boards you need to
run, you may be better off to have a full forced convection oven to cover
most of your board types. Vitronics 310 uses pure Infrared (4 top and 3
bottom zones) which heat is absorbed relative to the inherent physical
properties of the components. And due to the length of the oven is
short, you will have a hard time to control the "time above liquidus"
less than 60 seconds.

Subject: !st reflow oven
We are looking at puchasing a reflow oven for low volume periodic use. We
need
more throughput than a batch oven, but nothing like a large contract
house.
I don't have to be concerned with speed or throughput, but I do
have
to
be able to provide a repeatable consistent profile to impress my
customers as
far as quality is concerned.
Two ovens I am looking at used presently are:
Knight-Line 416 26" preheat, 30" reflow full convection 1yr old
Vitronics 310 IR 3 top 3 bottom zones
The used equipment dealer says he can sell me the VItronics for the same
price
-around $4k canadian as the Knight line. He insists it is a better value.
I
like
the full convection of the Knight line oven, and also that it is single
phase
220, as oppose to 3 phase. I might also use the full convection
properties of
the Knight for heat shrinking.
Any comments ?
