Remove paste from the screen and squeegees with a spatula and place in a
suitable container. Smear deposits are removed using a suitable cleaning cloth
dampened with a suitable solvent.
NOTE
Waste paste and contaminated cleaning cloths are to be disposed of in
accordance with local authority regulations.
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 productfile 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.
