I have just built a new factory and installed the old Heller 1707 XL oven. When I run the oven the LED panel lights and downlights in the entire building begin to shimmer after 2nd zone is switched on. It does not get worse when the whole 7 zones are

when I profile a customers oven / pcb I always try a check to see if there is basic oven temperature variation across its width....I have to say that in my experience I have never seen any significant variation on the Heller 1707EXL. Of course if you

Anyone have experience or advice to help prevent SMT reed switches from being blow out of position during re-flow? We are using a Heller 1707 MK 3. Is it possible to adjust air flow in the oven or do we need to glue before placement??

I have seen this on Heller1707 machines also for LED devices. The same job was run on anthoer brand oven (Rehm) and no issue. I think Heller Blower velocity can be a little on higher side as is a low inertia heating system and they have to make up f

We have a Heller 1707EXL that we purchased in 2006. During the first year we had 2 blower motors go bad. After the second one went bad, Heller sent a technician who replaced every blower motor on the oven at their expense. Since then it has been 5+

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
