Dave, if you have a level 6 then you have no other option then to bake it and reflow before it exceeds the specified floor life. For more details check out the joint IPC/JEDEC standard J-STD-033. It can be downloaded for free at http://www.jedec.org.

The 4713 is an old model, first came out in the late 80's. Recreated as 4713B, C & finally D. Check with UIC on the service issue. It shoots dots at around 18K per hour. Camalot is a far superior machine for liquid dispensing.
