2. Safety Information
a. Do not contact the Heater or its peripheral parts during operation.
b. Once turned off, let the unit cool completely before contacting. They are hot, you
will get burned.
c. When using fluxes, use fume extraction equipment or use in a well-ventilated
area to minimize operator exposure to fumes.
d. Do not use near combustible vapors.
e. Do not leave the equipment unattended when in use.
f. Do not open rear panel without disconnecting the main power cable.
3. Features
a. The TF 1700 and TF 2700 are ideal for post assembly rework, repair, and low
volume/short run production operations. The TF 1700 and TF 2700 can remove
and install PBGAs, CSPs, FCs, LGAs, LCC’s and other SMDs.
b. Featuring unparalleled thermal performance, PACE BGA Rework Stations
flexibility and state of the art process software means no other system is easier

System Operations Manual
www.paceworldwide.com Page 7 of 50
to use. The TF 1700 and TF2700 are a PC driven, semi-automated system that
requires a Pentium ® 4 PC featuring Windows XP® Professional OS. The unique
standard software package offers much more than just an operator interface.
PACE BGA Rework Stations advanced vision and placement system is highly
accurate and can quickly magnify even the smallest components for easy
alignment. TF 1700 and TF 2700 uses a combination of convective top heating
coupled with powerful IR bottom heating for an effective, repeatable heating
process.
c. Economical and easy to use, PACE BGA Rework Systems deliver high-end
BGA/CSP functionality, moving far beyond expensive, bulky rework machines by
offering unparalleled performance at an affordable price.
d. REFLOW FUNCTION
i. Unequalled programmability and process control ensures successful,
repeatable installation.
ii. The powerful and responsive 1200 Watt top heater, with closed loop
temperature control, coupled with proven nozzle design ensures uniform
temperature distribution when heating.
iii. High power bottom heater allow for successful and repeatable reflow at
safe, low temperatures.
iv. Profiles are programmed through the PC software.
v. Creating the perfect profile is easy with real time adjustment of profile
parameters through the PC.
vi. Store and recall an infinite number of profiles.
vii. Two pre-defined profiles for use as baselines when developing custom
profiles are included.
viii. Self contained, no external air supply or vacuum connections required.

ix. Semi-automated, motorized reflow head.
x. Four thermo-couple sensor inputs ensure successful profile development
and monitoring.
xi. External fan to cool PCB and component to below solder melt
temperatures after reflow.
e. ALIGNMENT AND PLACEMENT FUNCTION
i. The component is held by a precision vacuum placement pick, which is
located within the heater assembly.
ii. High resolution Color Vision Overlay System (VOS) with color camera
and dichroic prism. VOS does not require routine calibration, eliminating
costly downtime and operator frustration.
iii. Color Camera with 72x zoom capability, featuring auto-focus.
iv. Lighting system uses “Ultra Bright” White LEDs for maximum contrast of
lands and solder balls on component.
v. Independent lighting controls for component and PCB to maximize
overlay contrast.
vi. Retractable optics housing protects VOS from dirt and contamination.
vii. Accurately places any array package up to 65mm (2.5") square and as
small as 1 mm (.04”) square.
viii. Precise micrometer adjustment for X, and Y axis with Theta adjustment
ensures placement accuracy.
ix. High-flow vacuum pick holds component securely.
x. Images are viewed through the PC in standard or full screen viewing
options.
f. PRE-HEAT FUNCTION AND BOARD HOLDER

d. Inserting/changing nozzle. (Figure 3b)
i. Insert proper size nozzle. The OD of the nozzle should be 3 mm larger
than the outside of the component. If the proper nozzle size cannot fit
onto the PCB due to adjacent components being to close, use a smaller
nozzle or keep the nozzle approximately 1mm above the part. Align the
nozzle under the square hole in the reflow head. The nozzle snaps into
place. The nozzle can be positioned with the front surface parallel to the
PCB or at a diagonal by moving the lever on the nozzle housing. To
rotate the nozzle, first loosen the retention screw in front of the housing.
