Generally the heller exl range has issues in cross profile, some machines more than others. I have see as bad as 15 deg c and as low as 5 deg c ranging from entire length to a few zones. They never match the specification in reality. The markiii is

"His opinion was that you could never achieve 500cfm, even with a jet engine attached, as the outlet on the oven was too small..." I had that experience with a washer that blew steam out of the entrance. He said we'd collapse the pipe before we ever

Hi, we have plans to build up a SMD manufacturing line and would like to get your feedback what is best for us to choose. We are outsourcing about 50 different products which are more or less low series (up to 1000 pieces). Boards are very different

| 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
