OPE ATION

●Control card

Each Hakko 850D comes with a small card,

which inserts in the control slot in the front of

the unit. This card is used when entering data

for the process control functions. Any Hakko

850D card can be used with any Hakko 850D

SMD rework station.

Using the control card

The control card is used when a value is to be

changed or data are to be entered. The Hakko

850D will operate normally with the card

inserted. Remove the control card to lock the

data.

Setting/Changing the Temperature

CAUTION

The temperature setting range is 100 – 450°C (212 – 842°F).

●Attempt to enter a value outside the setting range will cause the display to begin flashing the HUNDREDS digit again.

Reenter a correct value.

●Both the display temperature and the temperature setting are the temperature at the sensor. (Even with the same

temperature setting, the temperature of the hot air differs depending on the nozzle size.)

Example: Change the temperature setting from 300 to 450°C.

PA AMETE S / INITIAL ESETTING

●QFP Desoldering

1. Set the temperature and adjust the air

flow control knob.

Set the temperature (refer to page 6) and

adjust the air flow control knob to desired

temperature and the level.

WA NING

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 F 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 F pick-up, adjust the width of the

pick-up by squeezing the wire. In case of

LCC 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. emove the IC.

Once the solder has melted, remove the IC

by lifting the F pick-up.

5. emove 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 quantity of solder paste

and install the SMD on the WB.

2. Preheat the SMD.

reheat the SMD as shown in the photo.

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.
