We are using ECD OvenRIDER to validate our reflow ovens on a weekly basis to have the data to show our customers that the board we ran 3 months ago saw the same oven condition as the one ran yesterday. Cp/ Cpk is calculated by ECD using a manually i

In 1995 we bought 4 Vitronics U520 reflow ovens with top heat only. We ran these ovens until 2003 for both curing and lead reflow with no problems. In 1998 we bought 1 U520 top and bottom heat and one U820 top and bottom heat and once again we had

Something else to keep in mind when you reflow using an IR (non-convection) oven. IR reflow is more susceptible to variations in board mass and coloration than convection ovens. Hi mass areas and dark colored parts will cause more variation in your

I had the very same problem but, did not question my oven as I knew the profile was good and I should have had even heating. So I then looked at pad size and layout. When Layout and size were found to be ok. I attached a prob to each pad and ran a pr

I need your help! We have been doing double sided surface mount for 4 years now. Up until 6 months ago I have not had a tombstoning problem. Since then I have a fairly high incidence rate of tombstones on the 0603 size resistors (no other parts).

| We are installing a new reflow oven and I have been told that we do not need to vent the exhaust out through the roof since we have a false ceiling. All that is required is to vent above the false ceiling and that the air exchange is great enough t
