Not actual, but from what I've seen, maybe a few mins to maybe over 5=20
mins as the tape needs to be threaded through certain sections, then the=20
feeder remounted.  If changing the part, then the software needs to be=20
told tht there's another part, assuming it allows swaps like that.  Or=20
run it as a separate job on the same boards with just different parts to=20
place.

This is why it pays to have a machine that can hold a lot of feeders.

The big boys (CEM's) have racks of just feeders pre-loaded with lots of=20
common components depending on what the job/boards require.  One CEM=20
just dedicated 12 feeders to my simple components and left them ready to=20
go for whenever I needed a batch run.
