Hi Dave,
I see two MAJOR advantages of a large oven:
1. More no. of heating zones and hence more flexibility and ease of
achieving the desired thermal profile.
2. Throughput. No. of boards processed per minute/per hour...
It's a very simple mathematical calculation:
If L is the length of the heating tunnel
D is the board length (in the direction of travel)
d is the distance between two boards
t is the desired profile time (total profile time)
then the no. of boards in the oven at a given point of time: L/(D+d)
Hence the no. of boards out per minute = [L/(D+d)]/t (assuming t is in
minutes)
Hope that answers your query!
Regards

Subject: [TN] Reflow Oven Sizes
What advantages does a larger reflow oven have over a smaller one other than
size? We have a small unit that will fit a 10" wide board. We would like a
unit that would fit a 13" wide board. Is there any other justifications to a
larger oven? We do not use lead free.
Thanks
Dave Snyder
