Thanks all for your replies. I ended up getting an older second hand machine (2003 Heller 1707 EXL) from a local company upgrading their assembly line. It is in mint conditions and was used in air conditioned room and had maintenance every 3 months.

If it's forced air convection I'd check all the circulating fans and filters. Also if its a clam shell bonnet make sure it's closed all the way and the seal is good. You didn't specify whether it is one zone or the full length of the oven, I do not w

We are seeing this the full length of the oven. We run a lot of double sided boards, so we cannot run them on the wire mesh. I checked inside the oven to ensure there was no build up of dropped parts that could block it. The temperature difference

Generally the heller exl range has issues in cross profile, some machines more than others. I have see as bad as 15 deg c and as low as 5 deg c ranging from entire length to a few zones. They never match the specification in reality. The markiii is

Most of this you have probably covered, but these are what have caused heating issues for us in our 1707 EXL. First, you would probably notice, but check that all blowers are turning by looking at there cooling fans in the top and bottom, Our 170

Typical problems with our heller 1707 EXL would be blower issues. We have almost replaced every blower on the top sense purchase. Fortunately Heller is very good about honoring there warranty on the blowers which is quite long, Might be lifetime not

I work with a small EMS shop that has extremely good capability because I created it for an R&D Lab for the U.S. Army. We have at times discussed leasing the equipment/facility to other companies who prefer that to farming out their work to an EMS.
