SYSTEM OVERVIEW
The Metcal QX2 Convection Rework System is designed to remove or to re-attach
SMT components from a PCB safely and easily. To reflow the solder joints, the QX2
uses carefully controlled focused hot air. The QX2 includes a semi-automatic vacuum
pick-up system that can be used to lift reflowed components from the board. For
precise process control, the QX2 displays the temperature and time for all operations.
The Metcal QX2 Convection Rework System consists of a power supply, a controller, a
work tray, and a nozzle removal tool. Optional accessories include a 355 mm x 508 mm
board holder that allows the PCB to be fixed in place and a 152 mm x 152 mm
convective preheater that provides under-board heat to reduce board warping.
The power supply provides airflow, vacuum and heat. It has a movable arm that
holds the heater head assembly, which contains the heating element and the vacuum
pick-up. Because no additional tool stand or work frame is needed, the QX2 saves
valuable work space.
The controller is all that is needed for you to control the power supply. It is attached
to the power supply by a cable, and it may be moved anywhere within the cable’s
reach. You can place it in the most convenient location.
The work tray provides a working surface for the PCB if you have not purchased the
optional board holder. Note that the preheater cannot be used with the work tray; it
must be used with the board holder.
The QX2 uses focused convection nozzles that are designed to fit specific components.
Nozzles are available separately so that you may select only the nozzles needed for the
application. The work tray can also be used to store nozzles.
The nozzle removal tool provides a way to hold hot components or hot nozzles
removed from the QX2. Simply hold the scoop side under the heater head to catch a
hot component. To remove nozzles, see Nozzle Removal (p.12).
The Z-axis knob allows fine adjustment of the height of the nozzle over the board. The
theta rotation lever is for positioning the nozzle squarely over the component without
needing to rotate the entire board. This lever is also used for quickly removing the
nozzle. Rotating the lever until it stops in either direction ejects the nozzle.

SYSTEM SET-UP
Place the main unit on a suitable workbench where you are not restricted for space
and can operate the unit in a comfortable manner.
If using the optional convection preheater, connect the cables and place the unit
underneath the heater head as described in the preheater instructions on page 9.
Place the work tray (or optional board holder) below the heater head.
Plug the power cord extending from the main unit (and optional preheater) into a
grounded wall socket of an appropriately rated input line voltage.
WARNING: To provide protection against the risk of electrical shock, connect only to
properly grounded outlets.
Connect the cable with phone-style connectors into the jacks on the back of the
controller and the back of the power supply.
Choose a nozzle and vacuum cup suited to your rework task.
Attach the vacuum cup by pushing it onto the vacuum tube. It is not necessary to
hold the tube. (See Vacuum Cup Attachment, p.11)
Attach the nozzle by pressing in firmly into the bottom of the heater head. (See
Nozzle Attachment, p.12)
Click the power switch located on the back of the main unit to the “On” position. The
controller display will show “Metcal QX2” for a few seconds.
The rework system is now set up and ready to rework your first component.
WARNING! PLEASE READ FOR YOUR SAFETY!
The air exiting the heater is VERY HOT. Do not put your hand or any other part of
your body under the heater head when the system is on.
The heater housing, nozzle and vacuum cup are all VERY HOT during and after use
of the system. Do not touch them with your bare hand until they have been allowed
to cool. DO NOT ASSUME THAT THE SYSTEM IS COOL JUST BECAUSE THE
POWER IS OFF. Always allow the system to cool before storage or re-packing.
A fire may arise if not used with care. Be careful when using the QX2 in places where
there are combustible materials. Never use the system in the presence of an explosive
atmosphere. Be aware of your surroundings; heat may be transferred to materials
which are out of sight.
Do not apply heat to the same location for a long period of time, and never leave the
QX2 unattended when in use.
To avoid the risk of electric shock, always plug the system into a properly grounded outlet.
If the supply cord is damaged, it must be replaced by the manufacturer or its service
agent or a similarly qualified person in order to avoid a hazard.

SYSTEM OPERATION
Airflow, vacuum, and timer are operated with the controller. The controller has a
mode selector switch that allows you to select the mode of operation: Remove or
Attach. There is also a single Start/Stop button that controls the two cycles.
The controller has an airflow selector that allows you to adjust the volume of airflow.
This determines the rate at which thermal energy is transferred from the heater to the
printed circuit board.
The LCD screen on the controller will display the following information:
OPERATION ICON
When the system is operating, the controller will display one of three animated icons:
Indicates the system is operating in Remove mode.
Indicates that removal is complete, but the vacuum cup is still holding the
component.
Indicates the system is operating in Attach mode.
TIME
Depending on the mode of operation, the timer will either count up or down. In the
Remove mode the display counts up and in the Attach mode the display counts down.
The +/- keys allow you to adjust the reflow time.
TEMPERATURE
Air temperature is displayed on the right, while cycle time is displayed on the left.
The temperature may be displayed in ˚C or ˚F, and the hot air temperature at the
heater or the temperature of an auxiliary thermocouple may be chosen (see Set-up
Mode & Calibration, p.8).

REMOVE MODE
Install a vacuum cup onto the vacuum tube extending from the reflow head.
(See Vacuum Cup Attachment, p.11)
Select a rework nozzle that corresponds with the component you wish to remove. Insert the
nozzle into the reflow head by firmly pushing the nozzle up until it clicks into place.
(See Nozzle Attachment, p.12)
Lift the heater head until it locks in the up position to allow clearance. Raise the heater head fully
by rotating the Z-axis knob until it comes to a stop. Place the printed circuit board that you wish
to rework on the work tray or board holder. Position the board holder or work tray so that the
componenttobereworkedcanbeeasilyaccessedbythereworknozzle.
Lower the heater head assembly until it locks in the down position. Move the work tray or
board holder so that the component to be removed is centered with reference to the nozzle.
Fine adjustments in the theta rotation axis can be made by rotating the lever.
Note: The component should be centered with respect to the nozzle so the leads do not hit
the nozzle when the component lifts from the board.
Using the Z-axis knob, lower the heater head until the nozzle completely encapsulates the
component. The nozzle should remain 1-2 mm above the component leads, and should not
be in contact with the component or PCB.
Ensure that the mode selector is in the Remove position, and that the main power switch is on.
Switch the airflow selector to the setting that best corresponds with the application. If you
are unsure which setting to use, start with the lowest setting, Setting 1. This setting is the
safest for the component and the PCB. To achieve faster removal times, increase the airflow
setting. WARNING: Higher airflow settings will increase the component temperature rise rate.
The table below provides sample airflow settings at the default Temperature Setpoint of
350ºC for three component sizes to maintain maximum component temperature rise rates
below 5ºC/s.
Component Setting
PLCC 20 1
QFP 100 1, 2
QFP 208 1, 2, 3
Press the Start/Stop button. You will now notice the hot air flowing from the flutes of the nozzle
andthetimercountingup.WARNING: The nozzle and the exhausted air will be hot.
If you have a preheater that is properly connected to the power supply, the preheater
will start automatically at the same time. If you do not wish to use the preheater, you
may turn it off. Alternatively you may turn it on before turning on the power supply.
(See Preheater Operation, p.10)
When the removal cycle is complete, the component will automatically lift from the printed circuit
board. The preheater will shut down and the hot air from the power supply will automatically stop.
The removal time will remain stored for a subsequent attachment cycle.
Lift the nozzle up by raising the heater head. The vacuum cup will continue to hold the
component. Flip over the nozzle removal tool so that the bottom plate is facing up and
acting as a scoop. Place the tool directly underneath the component and push the Start/Stop
button. The component will fall into the tool and the vacuum pump will turn off .
ATTACH MODE
After preparing the site, align the component you wish to attach to the PCB with its
mating land pattern.
Rotate the mode selector so that it is in Attach mode. You will notice that the vacuum
tube automatically lifts out of the way.
Lower the heater head and move the work tray (or optional board holder) so that the
component to be attached lies centralized in reference to the nozzle. Fine adjustments
can be made to the theta (rotation) axis at this point by rotating the theta rotation lever.
Lower the heater head until the nozzle completely encapsulates the component to be
attached by rotating the fine Z-axis adjustment knob. The nozzle should remain 1-2mm
above the component leads, and should not be in contact with the board or component.
You will notice the time of the last full cycle is displayed on the controller. You may
user the +/- keys to adjust the rework cycle time. If you just performed a removal cycle,
the time displayed is that removal time. If you are re-attaching the same component,
you may wish to add 15–30 seconds to the time to ensure complete reflow.
Press the Start/Stop button. The hot air cycle will now begin, counting down from the
displayed value. Once the timer gets to “:00” the unit will shut off airflow and
indicate that the placement cycle is now complete.

BOARD HOLDER
OVERVIEW
The board holder provides a self-centering mechanism for holding a PCB from
50 mm x 50 mm to 360 mm x 460 mm in size horizontally at a distance of 120 mm
from the workbench surface.
SET-UP
Place the board holder on a workbench with a level surface. The unit is now
ready for use.
OPERATION
Rotate the wheel of the board holder assembly clockwise or counterclockwise to
move the clamp rail in or out to accommodate the size of the PCB to be reworked
Position the PCB between the clamps. The clamps may be adjusted by sliding them
along the rails, to avoid interference with any components on the edge of the PCB.
They should support each corner equally if possible. Tighten the clamps gently by
rotating the wheel. Do not overtighten: the PCB may break or the clamps may be
damaged. The clamps will flex to accommodate thermal expansion of the PCB during
the rework process.

VACUUM CUP
ATTACHMENT
Remove the nozzle (see Nozzle Removal, p.12.)
Choose a vacuum cup that is properly sized for the component and the nozzle.
Push the vacuum cup up onto the vacuum tube. The vacuum tube will automatically
stop with the correct length of tube extended for the vacuum cup. DO NOT hold the
tube at the top or the cup will not be attached properly.
Be sure that the cup is attached level, so it will rest flush on the component. Vacuum
cups that are cocked may not hold a component.
REMOVAL
Remove the nozzle.
Use the notch in the Nozzle Removal Tool to pull the vacuum cup from the vacuum tube.
WARNING: The nozzle, cup and heater head may be hot.
MAINTENANCE
A clean and pliable vacuum cup is critical to proper component removal. Vacuum
cups will degrade over time and should be changed when they become brittle,
cracked, or torn. They should also be wiped cleaned of dirt and debris as necessary.
(See also Troubleshooting, p.14).
VACUUM TUBE MAINTENANCE
Over time, the vacuum tube may become clogged, especially if you have been using
flux, which can condense inside the tube. To clean the tube, first turn the system off
and allow it to cool. Then remove the flexible vacuum hose from the top of the tube at
the top of the heater head, and remove the vacuum cup from the bottom of the tube.
Run a stiff wire or rod (maximum diameter: 1.53mm) through the tube to clean it out.
PREHEATER
OVERVIEW
The preheater is designed to aid in the removal or the re-attachment of components
from a PCB safely and easily. The preheater uses forced convection to heat the entire
PCB evenly to just below the melting temperature of solder, allowing easy component
placement and removal, while minimizing the possibility of warping the PCB.
SET-UP
Plug the phone-style cable into the jack on the bottom of the preheater. Place the
preheater on a suitable workbench and stretch out the power cord and the phone
style cable behind the preheater.
WARNING: To provide protection against the risk of electrical shock, connect only to
properly grounded wall outlets.
Option 1
Lift the QX2 and place it over the preheater cables so that the cables are in the
grooves under the QX2. Place the three tabs in the back of the preheater over the
three slots in the base of the QX2. The preheater On/Off button and airflow control
knob will be facing you. Gently pull the preheater cables from the back of the QX2 to
remove any slack. Plug the phone-style connector into the jack on the back of the
QX2. Plug the preheater power cable into a grounded outlet.
Option 2
Place the preheater on the workbench ensuring that On/Off button and airflow control
knob are facing either your right or left. Plug the phone-style connector into the jack
on the back of the QX2. Plug the preheater power cable into a grounded outlet.
The preheater is now set-up and ready to aid in the rework of your first component.
OPERATION
The preheater delivers hot air to the bottom of the PCB. There are four power settings,
controlled by the airflow control knob (see figure above). The settings correlate to power
delivery of 150 to 950 watts, resulting in a PCB temperature range of 90 to 120ºC, with
an average across-board temperature gradient of 2ºC/cm. Choose a power setting
appropriate for your application. Use a higher setting for larger PCBs and quicker
removals. Use a lower setting for smaller PCBs and lower temperature ramp rates.
To start the preheater, press the On/Off Button. If the preheater is connected to the QX2,
it will turn on or off automatically with the QX2 operation cycle. To start the preheater
before the QX2, simply press the On/Off button prior to operating the QX2 unit.
