I'll check and let you know, Bob. I'm not sure what our Engineering department has planned for the older equipment.

Thanks, Bob Kondner -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Leland Woodall Sent: Wednesday, March 17, 2010 10:35 AM To: [log in to unmask] Subject: [TN] Reflow Oven Comparison and Qualification Technetters, We're preparing to purchase eight to ten forced convection reflow ovens to replace equipment we currently have. We also have plans to attend APEX to check out the varieties available and their features. Being a Quality guy, I'm concerned about items that include: Ability to hold temp within 1 to 2 degrees C Flux management systems Nitrogen control, with expected levels of 50 to 100 O2 PPM (max 500 PPM) Oxygen analyzer type, sampling rate, etc. Seals, exhaust system 8 to 10 zones Board drop sensors Auto width adjust Ability to maintain parallelism from end to end with constant use Ease of maintenance Power consumption, cost of ownership I know that I'm missing some important items. Will those that have a few minutes please add to my list and elaborate upon what I should investigate? I'd especially like to hear about personal experiences with critical control designs (what's good, and what should be avoided with all costs). Many thanks, as always!
