Instructions: Enter data from an existing oven profile (time and temperature readings) into the appropriate blue cells. Note the grey temperature cells at 175^o, 183^o, and 183^oC. Time readings must be entered at these temperatures to calculate time-above-liquidus (TAL) and to evaluate whether or not the Lee Dwell Criteria¹ has been met. If the user enters data for tunnel length, belt speed, product length, and product spacing into the appropriate blue cells, ReflowCoach^® calculates the throughput and profile time in the grey cells as shown in Figure 1. A grey cell also shows if the Lee Dwell Criteria (<0.25^oC/s for 40 seconds) has been met.
