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

(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 1)

(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.
