Put the Masking Tape (cotton tape) around the Flat
Package IC to protect other parts from any damage.
(Refer to Fig. 3-1.)

Fig. 3-1
NOTE
REMOVAL AND INSTALLATION OF
FLAT PACKAGE IC
Some ICs on the PCB are affixed with glue, so be
careful not to break or damage the foil of each IC
leads or solder lands under the IC when removing it.
NOTE
Masking is carried out on all the parts located within
10 mm distance from IC leads.
Blower type IC
desoldering machine
IC
Heat the IC leads using a blower type IC desoldering
machine. (Refer to Fig. 3-2.)
2.
Fig. 3-2
NOTE
Do not add the rotating and the back and forth
directions force on the IC, until IC can move back and
forth easily after desoldering the IC leads completely.
When IC starts moving back and forth easily after
desoldering completely, pickup the corner of the IC using
a tweezers and remove the IC by moving with the IC
desoldering machine. (Refer to Fig. 3-3.)

NOTE
When the IC leads are bent during soldering and/or
repairing, do not repair the bending of leads. If the
bending of leads are repaired, the pattern may be
damaged. So, be always sure to replace the IC in this
case.
Finally, confirm the soldering status on four sides of the
IC using a magnifying glass.
Confirm that no abnormality is found on the soldering
position and installation position of the parts around the
IC. If some abnormality is found, correct by resoldering.

INSTALLATION
Take care of the polarity of new IC and then install the
new IC fitting on the printed circuit pattern. Then solder
each lead on the diagonal positions of IC temporarily.
