Whether could we add some heating or cooling modules to the 8 zone reflow oven and convert the 8 zone to 12 zone or more?I 've never heard of anybody successfully done this.I think, this way, we could get more cost down.What's your opinions? Thanks®a

I've never heard of anyone doing this. Even if it were possible I can't believe it would be cost effective. If you absolutely need a 12 zone oven your best bet is to try and be a used/refurbed one if you can't afford a new one.

This sounds like something the saleman of your new Vitronics oven should be happy to help you sort through. ECD [and probably other profiler supplers] provide software for playing with [optimizing?] recipes. In it, they allow you to select from a v

I am most familiar with Heller (10 yrs. of 1088 4 zone - 1800 8 zone ovens) and find them to be very reliable. Other Manufacturers may have five zone ovens on the used market. (I used Petlock as an example because you could get data sheets/specs from

I would highly recomend an 8 zones (top and bottom heaters) oven as it has better flexibility than 7 zones. However, I would also would like to check for the heated length. Some oven has many zones but the heated length is small. Arman

From an operators stand point there really is no difference. I think what I work with now is a 7 zone and I have worked with 8 and 5 zone BTU ovens. The only difference I can really tell is on the 8 zone oven we had less bridging at the end. If you r

This has always been a big debate on what is better. Few things to consider before getting into number of zones. What is the throughput and cooling requirements? Throughput is a direct relation to length of heating zone. Longer heating length

This is easy! More zones means bigger process window and more thru-put depending on board size. More zones is always a good thing unless you're stapped for floor space. Just remember - the bigger the oven, the more it gets blammed for process prob
