3. WARNINGS, CAUTIONS AND NOTES
WARNING
Warnings and cautions are placed at critical points in this manual to direct the operator's
attention to significant items. They are defined as follows:
WARNING: Failure to comply with a WARNING may result in serious injury or death.
CAUTION: Failure to comply with a CAUTION may result in injury to the operator, or
damage to the items involved. Two examples are given below.
● Be sure to comply with following WARNINGS and CAUTIONS for your safety.
WARNING
● Be sure not to operate the unit with any combination of temperature and air flow settings
that makes the thermal protector trip (the heater lamp turns off during use). This could dam-
age the unit.
● After use, do not disconnect the plug during the automatic cool-down process.
CAUTION
When the power is ON, the temperature of the hot air and the nozzle ranges from 100 to
450°C. (212 to 842°F.). To avoid injury to personnel or damage to items in the work area,
observe the following:
● Do not direct the hot air toward personnel or touch the metal parts near the nozzle.
● Do not use the product near combustible gases or flammable materials.
● Advise those in the work area that the unit can reach very high temperatures and should be
considered potentially dangerous.
● Turn the power OFF when no longer using the HAKKO 850B or when leaving it unattended.
● Before replacing parts or storing the unit, allow the unit to cool and then turn the power OFF.
● To prevent accidents and failures, be sure to take the following precautions:
● Do not strike the handpiece against hard surfaces or otherwise subject it to physical shock.
This will damage the quartz glass shield around the heating element, and could damage the
heater as well.
● Be sure the unit is grounded. Always connect power to a grounded receptacle.
● Do not disassemble the pump.
● Do not modify the unit.
● Use only genuine HAKKO replacement parts.
● Do not wet the unit or use the unit with wet hands.
● Remove power cord by holding the plug - not the wires.
● Make sure the work area is well ventilated.
● The HAKKO 850B is not intended for use by children or infirm persons without supervision.
● Children should be supervised to ensure that they do not play with the HAKKO 850B.

5. PREPARATION: ASSEMBLY AND ELECTRICAL CONNECTION
Preparation: Assembly and Electrical Connection
A. Station Assembly
● Attach the handpiece holder.
Remove the handpiece holder mounting
screw from the side of the station. Attach
the handpiece holder to the station. (Figure
1)
(The handpiece holder can be installed on
either the left or right side.)
B. Handpiece Assembly
● Attach the nozzle.
Loosen the nozzle mounting screw. Attach
the nozzle as shown in the drawing.
(Figure 2)
C. Electrical Connection
and Power ON
1. Connect the power cord to the power
receptacle on the back panel of the
station. (Figure 4)
2. Place the handpiece on the holder.
(Figure 5)
3. Plug the power cord into a grounded
wall socket. After connection, the
automatic blowing function will start
sending air through the pipe, but the
heating element remains cool.
4. Turn the power switch ON.
NOTE: The power switch may be turned on
at any time while the automatic blow-
ing function is operating. Once the
power switch is turned on, the heat-
ing element will begin to warm up.
Tighten the nozzle
mounting screw.

(Figure 3)
Inside screw
(Figure 4)
When installing an optional
nozzle to the HAKKO 850B, do
not remove this inside screw.

(Figure 5)
CAUTION
This product is ESD-protected. Be
sure to use a grounded wall socket.
CAUTION
When not in use, place the hand-
piece on the holder.

6. OPERATION
● QFP Desoldering
1. Adjust the air flow and temperature
control knobs.
Refer to the temperature distribution
chart (page 8) to adjust the air flow and
temperature control knobs. Wait for
the temperature to stabilize for a short
period of time.
WARNING
If the thermal protector is tripped (the heater
lamp turns off during use), reduce the tem-
perature setting or increase the air flow. Be
sure not to operate the unit with temperature
and air flow settings that makes the thermal
protector trip. This could damage the unit.
2. Place the FP pick-up under the IC lead.
Slip the FP pick-up wire under the IC
lead. (Refer to the photo shown.)
If the width of the IC does not match the
size of the FP pick-up, adjust the width
of the pick-up by squeezing the wire.
In case of PLCC or small components
such as chip resistors, desolder by
using tweezers, etc.
3. Heating
Hold the handpiece so that the nozzle
is located directly over, but not touching
the IC, and allow the hot air to melt the
solder. Be careful not to touch the leads
of the IC with the nozzle.
4. Remove the IC.
Once the solder has melted, remove
the IC by lifting the FP pick-up.
5. Remove any remaining solder.
After removing the IC, remove
remaining solder with a soldering iron
and wick or desoldering tool.

● QFP Soldering
1. Apply the solder paste.
Apply the proper quality of solder paste
and install the SMD on the PWB.
2. Preheat the SMD.
Refer to the photo to preheat SMD.
3. Soldering
Heat the lead frame evenly.
4. Cleaning
When soldering is completed, clean
the residual flux from the board with an
appropriate cleaner.
NOTE:
Soldering with hot air has many advantages,
such as the inherent ability to pre-heat the
component being replaced. As with any
soldering process, however, there is always
the possibility of forming solder balls, bridges
between leads, and inadequate solder joints.
Always inspect the finished solder joints for
structural and electrical integrity.
● Turn the power switch off.
After the power switch is turned off, an au-
tomatic blowing function begins sending
cool air through the pipe in order to cool
the handpiece. Do not disconnect the plug
during this cooling process.
CAUTION
During the cooling process, the amount of air is
controlled by the setting of the air flow adjust-
ment knob. Hakko recommends setting the
knob at 8 when cooling for greatest efficiency.

7. MAINTENANCE / INSPECTION
● Broken heating element
A. Open the handpiece
1. Remove the three screws holding the
handpiece together. (Figure 1)
2. Move the tube away from the hand-
piece, as shown.
3. Open the handpiece. Disconnect the
grounding wire sleeve (1) and pipe from
the protruding portion of the handle.
Remove the pipe.
CAUTION
Quartz glass and heat insulation are inside
the pipe. Be careful not to drop or lose these
items.
4. Disconnect the connector (2) and
remove the heating element.
B. Measure the resistance
value
Connect an ohmmeter across the con-
nector terminals (a). The correct values
are approximately:
26-40Ω (100-120V), 70-100Ω (220-240V).
If the resistance value is incorrect, replace
the part.
(Refer to the instructions included with the
replacement part.)
CAUTION
Handle the heating element with care. Never
rub the heating element wire!
Insert the handle's projection into the hole in
the pipe.
● Replacing the fuse
1. Unplug the power cord from the power
receptacle.
2. Remove the fuse holder.
3. Replace the fuse.
5A (100-120V), 3.15A (220-240V)
4. Put the fuse holder back in place.

8. TEMPERATURE DISTRIBUTION CHART
CAUTION These charts are for reference. If the thermal protector trips, reduce the temperature set-
ting or increase the air flow.
NOTE: Air-flow and temperature adjustment of the HAKKO 850B
The temperature distribution chart relating air-flow and temperature settings for different nozzle types
provided with the HAKKO 850 are not to be used with the 850B. The 850B uses a different pump and
control system and the flow-rates and temperature do not correspond.
Please refer to the temperature distribution chart in the 850B instruction manual before use.
Test criteria: Measured at a point 3mm (0.12 in.) from the nozzle by recorder.
