I am seeing allot of issues with SOD-323's in our Heller Oven. The parts seem to move or blow off their pads. We do have all the fan speeds on low and still having this issue. The parts are sitting in the paste not on top, so there is some force o

I had similar issue with our new 1809 Heller Oven recently. It was blowing off some of the lighter parts. I tried kitchen exhaust fan mesh screen (you can pick this up at your local hardware store). Once I knew it was air flow issue, I played with b

We have a new Heller 1809 EXL reflow oven and when we run MELF�s or Aluminum Electrolytic Capacitors through the oven they are being blown off the pads. I have verified that the placement is good before reflow. I verified that they are pushed down
