Try lowering your blower speeds on the bottom zones. Works as well and lowering temps but easier to control than balancing your delta T from zone to zone.

Btw, our's was bought in 2001. So basically they said that it is not covered anymore. But we were never told that they changed the condition, until we were claiming for the blower. But in page 143 of the manual, it states, "...terms of this warranty

New Reflow Oven?

Bother are valid choices, Rehm is better made(stainless steel tunnel, lower power usage, threepahes blowers etc) If can afford it would be better choice. From experience Hellers Specs are a bit flaky... But they both will solder PCBs.

hi , we have Heller 1808 and I would say that is doing good job as oven. However for less than 3 years we had to replace 6-7 blowers. There are very nice machines in the market, but it really depends on you and how much money you are ready to spend.

We recently added a 7-zone Heller, and have had a 5-zone Heller for quite some time. When the tech installed our new oven, we were told the new oven does NOT have the lifetime warranty on heaters and blowers. However, when we order parts for the ol

Depending on Zone Temperatures, Belt Speed, and Board Density... Some Convection Ovens will drop Zone Temperatures faster than others. They recover by increasing Air Circulation. This can make parts fall off the Bottom-Side that otherwise would

Strange things ocuring during reflow...

Is your oven adjusted correctly for temperature > and blower and conveyor speed? As far as blower settings it only has a Hi-Mid-Low setting (is a heller 1809), and we have been working with all at Hi speed since line was started (1.5 year ago). Co
