1. When you measure temp on test board locations, you should get the same temp. 2. When you measure the profile temp., there will not be a temp. reduction between zone to zone 3. Friendly software 4. Possibility to change from oven to oven and getting the same profile results with the same parameters 5. Fast change from profile to profile 6. Smooth movement of the belt/net without any vibration Best Regards Reuven ROKAH e mail: [log in to unmask] Think green before printing this mail...

Ease of changing both. Get references for current users that have reached the claimed life expectance of these items and verify manufacturers claims.

May also want to consider different cooling options if you need more aggressive ramp down rate.
