Bother are valid choices, Rehm is better made(stainless steel tunnel, lower power usage, threepahes blowers etc) If can afford it would be better choice. From experience Hellers Specs are a bit flaky... But they both will solder PCBs.

JimPat, I travel to a lot of companies and I regularly hear complaints about pieces of equipment, new and used. The one piece of advice I would give is buy a main brand. Figure out your wants and needs to spec the oven and then buy a Vitronics, Hel

I'm using Kic Profiler and aluminium tape from Kic and thermocouples from Kic. They are good and reliable. I even manage to modify my heller 1088 by adjusting the fix conveyor and re-baffling the oven. Had dropped my 20-22 deg. C delta T down to 4.3

If you calculate CFM using the numbers you have provided you are pulling 1396CFM out of the oven. I am not sure what Hellers spec is but I know a Speedline OmniExcel Air machine should be set at 300CFM. I do know for a fact that to much exhaust can s

I have also seen on Heller ovens (even new ones EXL series) cross profile temperature differences over their spec of +/- 3 deg C, sometimes up to 7-10 deg C, 200-230mm from fixed rail. This can cause funny issues , profiling can cover this up and not

| Cpk's on top flight ovens (e.g., Conceptronics, Heller, Electrovert, Vitronics) vary wildly, from 1 to 2+, between different supplers. The suppliers don't seem to understand Cpk's. A supplier's rep whose oven has a Cpk of 1.0 told me: | 1. Cpk's
