Hi Al,
It might be worth considering adding one or two frames to allowing for buffering between stages.
In addition, in my experience you almost always end up with a few fixtures being out of service once they start to age - it's best
to get a couple of extra fixtures to cover for this eventuality.

Subject: [TN] Wave Solder Fixture Justification


Hello All:

Anybody out there have a rule-of-thumb or a formula used to determine how many
wave solder fixtures to purchase?

I'd like to keep the line going by having: 1 fixture being loaded with a pcb, 2
or 3 fixtures in the machine, 1 fixture being unloaded, and 2 or 3 in the
cleaner (I like to clean - OA flux - after every pass).

Using the above sample, 6 to 8 wave solder fixtures would be required.


Thanks in advance,
