PIK AND PASTE
Located in the middle of the front panel, you will find the PIK
AND PASTE section of the PRC 2000. The Pik-Vac feature
provides a quiet and gentle vacuum source to the Pik-Vac wand
for use in handling and placing your surface mount parts.
Turning on the PIK-VAC Power Switch will cause a continuous
vacuum to be made available to the pick. A variety of tip and
vacuum cups are supplied to handle most surface mount parts.
The Green LED will light to indicate when the PIK-VAC is
running. There is also a low pressure auxiliary PIK
PRESSURE Port located on the rear panel which can be used
to operate low pressure accessories such as a sprayer.
The paste dispensing system occupies the right half of the PIK
AND PASTE section of the PRC 2000 and can dispense a
variety of solder cremes, fluxes, potting compounds and
adhesives. The Paste Dispense air hose comes equipped to
accept standard 10cc material barrels. The self-contained
pump supplies nominal 40psi (.28 MPa) of air pressure to the
syringe. Above the PASTE DISP Port, you will find a 2-
position switch labeled TIMED and CONT (Continuous). In the
continuous (CONT) position the dispenser pump will supply
continuous air pressure to the syringe while the foot pedal
remains depressed (FOOT PEDAL Selector Switch in "PD"
position). In the "TIMED" position, the control knob above the
switch becomes active. Each depression of the foot pedal will
activate the pump from 0.1 to 10 seconds. The LED will light
Yellow to indicate when the pump is running and will shift to Green when air pressure is being applied to
the syringe.
Whenever the FOOT PEDAL Selector Switch is in the "PD" position, the
pump will periodically run for short periods to maintain internal pressure. The
pump will continue to run (Yellow LED lit) while the system recharges.
As with any dispensing system, when thick viscous material or solder paste
is to be dispensed, ensure that the material is fresh, has been stored
properly and is at room temperature as per supplier's recommendations.
