INTRODUCTION
The PRC 2000 is a Process Control System for Universal Assembly and Repair of Electronic
Assemblies. The systems include the power source with a selection of accessories and functional aids.
The systems are available in a variety of package configurations to suit your needs.
The PRC 2000 systems are available in either the 100 VAC version, the 115 VAC version or the 230 VAC
version. The Power Source houses five functional sections. The following is a brief description of each
section.
The PRC 2000 THERMAL MANAGEMENT CENTER incorporates outputs for specialized SensaTemp
handpieces for safe installation and removal of virtually all surface mount and thru-hole components.
Three auxiliary channels provide SensaTemp control of separately sold AC line-powered accessories.
Continuous automatic calibration, auto power down and a built-in software password function assure
consistent operator performance, reliability and security.
The PIK AND PASTE section features a self-contained high pressure air supply with timing control for
precise dispensing of solder paste and other materials. The vacuum pick has a finger actuated release
for convenient component handling.
The PRC 2000 MICROCHINE is a lightweight, variable speed machining handpiece for precise circuitry
and substrate repair. With its tachometer feedback, the MicroChine can maintain controlled drilling and
milling rates under varying loads. The MicroChine’s patent pending PROBE BRAKE feature instantly
stops machining at a selected layer depth for safe multilayer repair.
The PULSE HEAT section provides variable controlled, low voltage AC pulse power to an array of
specialized handpieces for safe surface mount rework, circuitry repair, auxiliary heating, coating removal
and thermal wire stripping.

CAPABILITIES
Your new PRC 2000 is the most advanced, self-contained rework and repair system ever created for the
service bench or manual production workstation. The case's T-slot channels allow you to configure PRC
2000 accessories to suit individual operator preferences. The new style Tip & Tool Stands and Hot
Cubbies can be mounted to the T-slot channels or set up freestanding (with the purchase of optional
"Stand Alone" cubby upgrades for Hot Cubbies). This offers great versatility when the unit is shared by
several operators who may have different layout preferences.

11
PRIMARY CONTROLS
In the upper left hand corner, you will find the master POWER Switch which controls all power to the unit.
Just to the right of the POWER Switch is a 4-position FOOT PEDAL Selector Switch which directs the
action of the foot pedal connected to the FOOT PEDAL Receptacle (rear panel). This ensures that only
one of the listed functions is activated by the foot pedal at any one time. The switch positions are as
follows:
PH - Pulse Heat,
PP - Pulse Plate,
MC - MicroChine,
Figure 1. Primary Controls
PD - Paste Dispenser.
NOTE
Although vacuum and air pressure to air-operated SensaTemp handpieces
is controlled by finger actuated handpiece switches, a second foot pedal can
be connected to any Auxiliary (AUX) channel receptacles (rear panel) of the
THERMAL MANAGEMENT CENTER to control vacuum or air pressure to
these handpieces.

12
PULSE HEAT
At the lower left of the control panel you will find the PULSE HEAT section of the PRC 2000. The two AC
jacks are for connecting the Universal Power Cord to the PRC 2000 system. The cord will accept several
quick connect/disconnect handpieces including the LapFlo, ResisTweez, ConducTweez (optional) and
StripTweez (optional) which can be changed within 2 seconds. Pulse Heat handpieces with non-
solderable, rapid heat up/cool down tips offer unique advantages in many SMT rework, conformal coating
removal, soldering and auxiliary heating applications. With many Surface Mount Devices (SMDs) it is not
only important to achieve the solder reflow temperature, but to control the way in which you arrive at that
temperature. Many of the newer SMDs are very sensitive to thermal shock and overheating. The intrinsic
slow temperature ramp-up (rise time) of the Pulse Heat handpieces provide an extra measure of safety for
such components. Always consult your organization's specifications or the component manufacturer's
guidelines. Some very sensitive components may require controlled preheating (e.g., with the PACE
HotSpot temperature controlled heating surface).
Figure 2. Pulse Heat Section

13
NOTE
The ResisTweez resistance soldering handpiece by its very nature may have
a potential leakage voltage above 2mV. Its use should be restricted to
soldering and auxiliary heating applications in which there is no risk of
electrical over stress (EOS) discharge damage to sensitive components.
PACE ThermoBand tips, which fit the ResisTweez, are specially insulated
to keep leakage below 2mV.
The control knob located above the AC terminals (PULSE HEAT Output Control) controls the amount of
energy delivered to the handpieces. The Green LED will light to indicate that current is flowing to the
handpiece when the foot pedal has been depressed.
PULSE PLATE
The PULSE PLATE section located just to the right of the
PULSE HEAT section allows the operator to safely replate
damaged, worn or repaired connectors, circuit contacts and
edge connectors using simple plating solutions. The swab
plating probe and ground clip connect to the terminals labeled
“DC” while the control knob can be adjusted to regulate the
amount of voltage applied to the area being plated. The
Green LED will light to indicate that voltage is being applied
when the foot pedal is depressed. The LED will shift from
Green to Red if an overcurrent condition is reached. Contact
your local PACE representative for information regarding the
optional PE-210 SwaPlating accessory (P/N 7003-0002) to
the PRC 2000 system. Figure 3. Pulse Plate Section

14
MICROCHINE
The MICROCHINE represents the latest PACE development in hand machining for the circuit board rework
and repair. The self-contained motor handpiece connects to the PRC 2000 via a special connector. The
motor unit can be actuated by a fingertip control switch or the foot pedal. A tachometer feedback loop
between the motor and controller keeps the speed that you select constant as the load on the motor
changes. Below and to the right of the MICROCHINE you will find a connection jack labeled “PROBE
BRAKE” which offers additional control of milling and drilling operations. Connecting the probe to a
conductive element where you wish machining to stop will cause the motor to stop immediately as soon
as contact is made. This feature can also be used to protect other circuit elements (e.g., adjacent lands
or circuit traces) when machining in the tight spaces often found on todays’ circuit assemblies. The LED
will light Green when the unit is running and Red when the probe brake has been activated. The LED will
shift its color from Green to Yellow when the motor has reached its maximum load. This is normally an
indication that too much pressure is being applied to the workpiece. The control knob regulates the speed
of the motor unit so that it can be easily set for the work to be performed. The MicroChine uses the same
collet previously found in the PACE MiniChine systems, so that all existing bits will be interchangeable
and features the same special static dissipative housing material found in all PACE soldering/desoldering
handpieces. An optional chuck is available to accomodate variable shank diameter bits.
Figure 4. MicroChine Section

15
Figure 5. Pik And Paste Section
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.
NOTE
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.
NOTE
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.

16
THERMAL MANAGEMENT CENTER
The THERMAL MANAGEMENT CENTER occupying the right 1/3 of the front panel is the heart of your
PRC 2000 system. This microprocessor based multi-channel center can control up to six devices at one
time. To the left of the Digital Readout are the three LEDs which indicate the "Current Channel" (i.e., the
channel whose temperature information can be adjusted and is displayed on the Digital Readout (CH 1,
CH 2 and CH 3)). Below these is the Green AUX (Auxiliary) LED. When this LED is lit in conjunction
with one of the channel LEDs, the Digital Readout displays temperature information of the three auxiliary
channels located on the rear panel. To the right of the Digital Readout is the °F/°C Key which allows the
operator to switch instantly between a ° F and ° C display. Located just below the Digital Readout is an
array of five keys. In normal operation, these keys control channel selection, tip temperature and tip
temperature offset settings. The two keys with up and down arrows are used for scrolling the
temperature and offset settings up and down. The LEDs located above the SET and OFFSET Keys
normally indicate which function is being adjusted. In Calibration (CAL) Mode, these same keys are also
used for entering, setting and clearing the password features as well as adjusting temperature
parameters and system set-up. By entering the tip temperature offset and the tip temperature, the true
tip temperature will be displayed on the Digital Readout. All these features will be discussed in the
operation section of the manual. Below the keys are three receptacles for attaching any three low
voltage SensaTemp handpieces in any configuration up to 100 watts/channel (300 watts total) power.
There are three additional receptacles on the lower left section of the rear panel. These will accept up to
three additional, externally powered, devices which are temperature controlled by the THERMAL
MANAGEMENT CENTER. As an alternative, any of the rear panel receptacles can accept a foot pedal
which will control the internal vacuum/pressure pump in addition to using the finger-actuated switches
found on the SensaTemp handpieces. SensaTemp handpieces available for use with your PRC 2000
include:
SP-2A Sodr-Pen Soldering Iron,
SP-1A Sodr-Pen Soldering Iron,
SX-70 Sodr-X-Tractor Handpiece,
TT-65 ThermoTweez Handpiece,
TP-65 ThermoPik Handpiece,
DTP-80 Dual ThermoPik Handpiece,
TJ-70 Mini ThermoJet Handpiece.
Just to the left of the three SENSATEMP receptacles is a grounding jack which will accept a standard
banana plug. This can be used for grounding the operation, the work or additional equipment. To the right
of the SENSATEMP receptacles you will find the SNAP-VAC Vacuum and Controllable PRESSURE Ports.
The SNAP-VAC Port (bottom) should always have a VisiFilter attached in order to protect the vacuum
pump from any ingested material and to help muffle noise when the motor is running. The Controllable
PRESSURE Port (top) is used to supply air to the Mini ThermoJet handpiece. The rate of delivered air flow
