The optional paste dispenser is only utilised when the machine is fitted with squeegees. The paste dispenser dispenses a precise quantity of solder paste equal in length to the print width and along a line calculated from the print stroke start position and the size of board.
Dispensing operations can either be programmed to occur at predefined intervals with respect to board count, in direct response to the operator requesting a dispense via the MMI or called from DEK’s optional 2Di inspection software.
Applying pneumatic pressure to a paste cartridge installed in a special holder dispenses the paste. The paste dispenser is mounted on a pivot, which is driven by a dc motor to the vertical position for dispensing paste.
The paste dispenser mechanism is driven along the horizontal rail of the paste dispense carriage, which is mounted on the rear of the print carriage. This drive together with the movement of the print carriage enables the paste dispenser to be moved parallel to the squeegee blades in order to dispense paste anywhere on the stencil.
