Hi Blair
You must have a lot of feeders!

We monitor our feeder requirements and our goal is to have enough
feeders that we have one job running on the machine, the next job loaded
on feeders already, and are able to work on loading the subsequent job.
So essentially we are able to have three jobs loaded at once.

This has worked well for us, the changeover time is pretty reasonable.

regards,
 - Graham

Subject: [TN] Feeders

As an OEM we have had a policy that wenever our Engineering group wants
to 
use a new SMT part for product we purchase a feeder for that part. Thus,

when we change over from one product to another, we simply need to swap 
feeders. 

A sister company does it differently - they take reels off the feeders
and put 
a new reel on the feeder and then put the feeder back on the machine. 

Our approach would seem to cut down on changeover time (although you 
could have two sets of feeders, and swap reels for the next job while
the 
machine is running the current job), but is inherently more expensive, 
considering the cost of feeders. 

Just wondering what the others in industry do...

Blair
