Multihead dispensing

XYFLEX is a flexible liquid-dispensing system that dispenses up to 140,000 dots/hr and can therefore keep pace with chip shooters that place components at rates of 40,000-90,000 pph. The system, consisting of four heads and up to eight pumps, can dispense solder paste, adhesives, conductive epoxies, encapsulants, and flip chip underfill - at the same time and at different programmable speeds. It can be installed as an in-line system with the ability to meet the throughput requirements of high-volume pick-and-place machines. At the maximum speed of 140,000 dph, placement accuracy is ?0.003 in. (?75 ?m) at 3s; at 125,000 dph, placement accuracy is ?0.002 in. (?50 ?m).
