I would go with a 7-zone oven. A 5-zone oven would get you by, but for a little more you could get a 7-zone that will handle a more challenging reflow process as will as more volume.

Depending on the part say a cc1206 capacitor try a 7 degree theta rotation.

Larry, 180 Deg. C (?) to start the profile seems a tad on the high side for a 7-zone oven. You risk too high of a ramp rate and solder beading. At 7 zones, there's no reason to get too hot that fast.

Yes we are using a 7 zone and a ramp to spike. How do you handle your solder paste and what printing methods do you use?

I've seen this problem caused by the cool down. On a 7 zone oven I made a profile to peak at zone 5 to give some semblance of control to the cool down. The component can develope a big delta T, because of the difference of materials

Anybody ever see what happens to a wave solder machine in a 7.0 quake? Can you say tsunami? What a mess.

Hi Scott, My Heller is a bog standard Heller 1500 with an edge guide. There is nothing special about it. I would of course love to have a 7 zone oven, but...I have to use what is here at this time. My only concern with a 5 zone oven is the change i

Billy, We have a 7 year old Vitronics SMR-800N. Try "user". If not, call or e-mail Jay Denuzzia at Vitronics-Soltec (email@example.com).

Be carefull of the effect on other components with a 7mil stencil, like fine-pitch devices will bridge more, excess solder.
