Paul, My company offers an excellent solution for low volume/high mix applications. The issue always becomes how can you reduce downtime/changeover. There are few features on our machines that allow you to do this effectively: -Load feeder

We use both labels and lasers to mark our boards. Since implementing the lasers, the downtime attributed to bar code labels on those lines have dropped to virtually nothing. We still have problems with the labels wrinkling during reflow making read

Put the new stuff in the back and pull from the front. A pass through from stores makes that a lot easier. Bar codes are a wonderful thing if you can get people to use them. Wand it into stores then wand it sequentially into production via a queue.

My personal favorite is the Siemens F series and the UIC GSM platform. Both Siemens and UIC have awesome resources for csp, flipchip and baredie processing - Siemens= Dan Baldwin from GaTech; UIC = George Westby from UIC labs. My second choice would
