Thank you for purchasing the Hakko 850B SMD Rework
Station.
The Hakko 850B is designed to solder and desolder surface
mounted devices with hot air.
Please read this manual before operating the Hakko 850B.
Keep this manual readily accessible for reference.
●
TABLE OF CONTENTS
PACKING LIST / SPECIFICATIONS....................................................... 1
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:
W ARNING: Failure to comply with a WARNING may result in serious injury or death.
CAUTION: Failure to comply with a CA UTION ma y result in injury to the operator , or
damage to the items involved. Two examples are giv en below.
●●
● Be sure to comply with following WARNINGS and CAUTIONS for your safety.
●●
W ARNING
● 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 damage 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 flammab le 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 shoc k. This
will damage the quartz glass shield around the heating element, and could damage the heater
as well.
● Be sure the unit is grounded. Alw ays 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 po wer 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.

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.)
(Figure 1)
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. T urn the pow er switch ON.
NOTE: The power switch may be turned on at
any time while the automatic blowing
function is operating. Once the power
switch is turned on, the heating element
will begin to warm up.
Tighten the nozzle
mounting screw.
Inside screw
(Figure 2)
(Figure 3)
When installing an optional
nozzle to the Hakko 850B, do
not remove this inside screw.

CAUTION
This product is ESD-protected. Be sure to use a g rounded wall
socket.

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 temperature 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.
Temperature control knob
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, remov e remaining
solder with a soldering iron and wick or
desoldering tool.

OPERATION
●●
● 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 ev enly.
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
automatic 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 adjustment
knbob. Hakko recommends setting the knob at 8
when cooling for greatest efficiency.

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 handpiece,
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.
(Figure 1)
Connector (2)
4. Disconnect the connector (2) and remove
the heating element.
B. Measure the resistance
value
Connect an ohmmeter across the connector
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.
