Introduction:
Thank you for purchasing the TF 2000 BGA/CSP Rework Station. As
electronic devices continue to get smaller, lighter and more compact,
components and printed circuit boards are also becoming smaller and the
amount of available space on PCBs is continually decreasing. In order to
maximize board space, area array devices are growing in popularity. Area
array devices are BGAs, CSPs and “micro-BGAs”, and Flip Chips. These
devices require an optical overlay vision system to ensure proper placement
and high levels of process control during rework to ensure successful
installation. The TF 2000 has been specifically designed to rework these
types of components and can also install and remove a variety of other SMT
devices.
NOTE: This device complies with part 15 of the FCC rules. Operation
is subject to the following two conditions: (1) This device may
not cause harmful interference and (2) This device must accept
any interference received, including interference that may cause
undesired operation.
The TF 2000 also complies with 98/37/EC and 89/336/EEC.
Caution: During normal operation, the top heater, nozzle, bottom-
side-heater(s) and halogen lamps will get hot. Do not
contact them directly as serious injury could occur.

Features
1. The TF 2000 System is comprised of three self-contained stations:
The Reflow Station (Model TF 2000R)
The Placement Station (Model TF 2000P), and
The Base/Pre-Heater Station (Models TF 2000B, TF 2000BE, TF
2000BL, or TF 2000BLE)
Each individual station is lightweight and compact, allowing for easy
set-up and portability.
2. Up to 40 reflow profiles can be stored by the TF 2000. Saved profiles
can be recalled at the touch of a button and are displayed on the LCD
display panel.
3. A colored LED indicates each phase of the reflow cycle so the status of
each operation can be easily seen and monitored.
4. The Placement Station can easily handle components up to 70 mm
square. If needed, a split screen function is available through the
optional software package.
5. A highly efficient, 1000-watt topside heater used in conjunction with a
truly unique nozzle design insures the uniformity of the temperature
across the assembly.
6. The ceramic panel bottom side heater with a wide heating area is
incorporated to insure the co-planarity of the PCB, to prevent warping,
and to enhance the reflow of large BGAs.
7. The blower and vacuum pumps are self-contained. No external air
supplies are required.
8. A cooling fan automatically activates at the end of the reflow cycle to
cool the component, PCB, and nozzle.
9. The TF 2000 is versatile, adaptable and ensures repeatable results.

J) Optics Housing Contains the camera and beam splitter. The
housing is retractable and should be kept in the
retracted position when not in use. The lights for
the optics will turn on/off automatically when the
housing is extended.
K) Bottom Side Heater Used to warm the PCB from the underside. It is
an IR type of heating source. The pre-heater
temperature is set in the “PRE-HEAT” display and
will remain on throughout the reflow cycle. When
the cycle enters the reflow phase, the bottom-side
heater temperature will increase by 30ºC to ensure
successful reflow. A power consumption indicator
light is mounted onto the pre-heater to indicate
when it is drawing power.
**NOTE: For TF 2000L/LE models, refer to
Section 10 for model differences.

2 OPERATION
2-1 Before Operating
•Make sure the TF 2000 is on a stable platform
•It is recommended that the TF 2000 be turned on for at least 15
minutes before use to ensure the Bottom Side heater has reached
its set temperature and stabilized. Once the bottom-side heater is
at temperature it will deliver consistent heating, ensuring highly
repeatable heating from operation to operation.
•It is advisable to conduct a trial operation each day to ensure all
systems are operating properly. Also, it is important to verify the
airflow of the unit: Maximum airflow is 25 l/min and Minimum
airflow is 18 l/min.
•Verify that the devices/parts being soldered to the PCB do not
exceed the height limitations. Exceeding the limitations may
interfere with the operation of the machine.
1. The maximum height of any component or device on the top
of the PCB is limited to 30 mm (1.2”).
2. The maximum height of any component or device on the
bottom of the PCB is limited to 15 mm (0.6”).
2-2 General Operating Procedure
1. Insert PCB into Board Holder. See Figure 4.
Figure 4: Board Holder and PCB
2. Apply flux or solder paste: One of the following methods is
applicable depending on the rework conditions, the specification of
Device/PCB, or operator preference.
A) Dispense flux on the land pattern using a brush or flux
pencil.
B) Apply solder paste to the land pattern using a conventional
