The patented Horizontal ConvectionTM technology circulates heated air in each chamber around the board front to back which increases the thermal effi- ciency and uniformity within each zone. This expos- es the circuit board to a uniform temperature profile along the entire assembly. Cyclonic generator speed is independently set in each zone. with stand option The temperature profiling accessory kit includes all the accessories you need to profile PC boards through your reflow oven.
