As a volumetric dispensing procedure, we often use the precision screw dispensing unit. This is suitable for the dispensing of media with fillers such as conductive adhesive or solder paste.
The drive of the screw dispensing unit is permanently monitored, so that dispensing patterns and axis movements can be synchronized with the rotation of the screw. The unit is built very lean. Therefore, even the tightest places of a workpiece can be reached. If there are multiple dispensing axes in operation, the screw dispenser can be combined with other dispensing systems. Hence, it is for instance possible to lay a dam with the screw, which is afterwards filled by the jetter.
The screw dispensing unit is automatically calibrated on all of our machines. With the integrated vision system, the dispensing result can additionally be rated qualitatively and quantitatively.
As an alternative to the screw dispensing unit, piston dispensing systems can also be used.
