In-line dispensing

The CAM/ALOT 3600 in-line liquid dispensing system uses a combination of convection and quartz heating for flip-chip assembly to maintain the substrate at 80-100?C during pre-dispense, dispense, and post-dispense stages of underfill. The 3600 is designed with an integrated oven for consistent noncontact heating of FR4, ceramic, or flex circuits; it can complete up to 700 units/hr on a maximum effective dispense area of 250 ? 300 mm. System features include automatic vision for exact die alignment; rotary positive displacement pump technology; touch-probe z-axis sensing; precision ground ball screws and closed-loop servo motors on x, y, and z axes; and product loaders/unloaders.
