Small components blown issue could be due to one of the below. - Process issue; Make sure solder paste is fresh, if flux is drying out it will not hold parts properly. Check downward pressure of Pick Place. SOT may have to be pushed a little harder i

I'm suprise that you are not evaloating HELLER ovens ,It is the best ,relaible oven in the market for more than 5 years. They are using the same heater/blower technology from the same manufacturer for years... HELLER offers LIFE WARRENTY for the heat

More zones = higher thruput. Is it better to have (8) 12 inch zones vs. (7) 15 inch zones? One thought might be more parts = more cost = more potential for failure. I have a bunch of BTU's with over 12,000 heating hours of combined opertion. I

The same with Russ, I would look at Vitronics and BTU. based on my experience they give best results especially on the profile. Maintenace is also superb! BTU has modular blower, heater T/C assy. Vitronics is "XPM - NO PM System" Now, BTU offers lif

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

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
