CHAPTER 10 PASTE DISPENSER SYSTEM
MODULE OVERVIEW
Purpose The optional paste dispenser is only utilized when the machine is fitted with
squeegees. The purpose of the paste dispenser is to dispense a precise
quantity of solder paste which is equal in length to the print width and along a
line which is calculated from the print stroke start position and the size of the
board.
The paste is dispensed by applying pneumatic pressure to a paste cartridge
installed in a special holder. The paste dispenser is mounted on a pivot which
is driven by a dc motor to the vertical position for dispensing paste.
Elements The paste dispense is a stepper driven system comprising:
• Paste Dispense Carriage
• Paste Carriage Stepper Motor
• Cartridge Horizontal (Up) Sensor
• Cartridge Vertical (Down) Sensor
• Paste Dispenser
• Cartridge Empty Sensor
• Paste Dispense Carriage Bearing
• Paste Carriage Home Sensor
• Cartridge Tilt Motor
Operation The paste dispenser mechanism is driven along the horizontal rail of the paste
dispense carriage, which is mounted on 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 screen.
The system can control the quantity of paste dispensed in the following ways:
Machine programmable:
• Dispense speed
• Dispense rate
• Start and stop positions
User Setting:
• Dispense air pressure
• Nozzle size
The paste dispense system uses 1kg paste cartridges. 500g paste cartridges
may be used with the aid of an additional spacer.
