Auto Dispense An alternative to manual loading of solder paste to the screen is given with the

provision of an automatic paste dispenser. This is mounted to the rear of the

print carriage.

The paste dispenser uses either a 1 Kg or 500g cartridge. The 500g cartridge

requires the fitting of a sleeve which is an option. This enables any loading of

paste to be carried out without the need for the operator to handle the paste.

A slug inside the cartridge, travels down the cartridge as the paste is used. A

proximity sensor fitted to the side of the dispenser detects the metal content of

the paste. When the cartridge is empty the sensor initiates a ‘Print Medium

Low. Please Replenish’ warning window to the operator.

Programming into a

Product File

The paste dispense parameters can be setup when editing a product file for a new

product, although it may be more convenient to set these after the product has

been run for a while and paste requirements have been determined.

The parameters to be edited that affect the operation of the paste dispenser are:

Paste Dispense Rate:

This determines the frequency of the cycling of the paste dispenser. The setting

is gauged by running the product and noting the number of prints before paste

replenishment is required. This can be set to any number between 0 to 100 in

increments of 1.

Paste Dispense Speed:

This determines the speed at which the paste dispenser travels across the screen

and hence the amount of paste which is dispensed. This parameter needs to be

set in conjunction with the Paste Dispense Rate. This can be set to any number

between 10mm/s and 100mm/s in increments of 1mm/s.

automatic dispense, go to Step 13. If the paste dispenser is low on paste a

warning window is displayed. The warning window varies, depending on

the setting of the consumable action option in set preferences. If the set

preference is set to warn, continue with Step 4. If the set preference is set to

pause or suspend go to Step 8.
