We screen print epoxy adhesive, place components then run the board through our adhesive oven (2-5 min cure at 150�C). This is in addition to reflow.

Received an info that the longer the oven the higher the throughput. What's the formula when calculating oven throughput ? say, i have the following: Oven Length : 266 cm Conveyor Speed: 29cm/min PCB Length: 29 cm Gap per Board: PCB Length x 0.5
