Units that are board mounted for environmental testing must see a peak temperature in the reflow (Derived using 6-zone Convection Oven) zone, as specified. This is to ensure that all test units will see worst case conditions. 4. Ramp down rate to be measured from 245 C to 150 C. 5. Process Description 8 does not apply to open frame trimmers.
