We are running a Heller 1707 EXL reflow oven, but we have a temperature variation across the board. When the oven first comes up to temperature, the centre of the board is 10degC hotter than the inside rail which is a further 10degC hotter than the

We have been using a Heller 1707EXL (7 zones + 1 cooldown zone) for lead free (ROHS) soldering since 2007 with good results. I wouldn't go any lower than 7 heat zones though. If I may brag a bit....The IPC-7095 revision C standard was released a fe

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

Is this a new issue? You could run a wide piece of masking or duct tape along the oven seal on the outside just to see what happens. What is the heating plate configuration. Are they solid from front to back or split. My thought here is if there is a

We have a Heller 1707EXL that we use for lead and lead-free production. It has both a mesh belt and edge rails. We run 90% of our assemblies on the mesh belt (leaving the edge rails wide open). I have noticed when profiling a board on the mesh bel

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
