The automatic dispensation unit ADU (ASYS Dispenser Unit) serves to apply almost arbitrary sticking or sealing lacquers on PCBs. The PCBs run on a conveyor belt into the machine and there they are accurately aligned and held on through several clamping and centring devices. A gluer which can be moved by the built-in X/Y/Z portal system, applies glue on the destined component of the PCB.
