DISASSEMBLY INSTRUCTIONS

2. REMOVAL AND INSTALLATION OF FLAT

PACKAGE IC

REMOVAL

1. Put the Masking Tape (cotton tape) around the Flat

Package IC to protect other parts from any damage.

(Refer to Fig. 2-1.) NOTE

Masking is carried out on all the parts located within 10 mm distance from IC leads.

Masking Tape (Cotton Tape)

2. Heat the IC leads using a blower type IC desoldering

machine. (Refer to Fig. 2-2.)

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.

3. 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. 2-3.)

NOTE

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.

INSTALLATION

1. 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.

(Refer to Fig. 2-5.)

Soldering Iron

Solder temporarily

Fig. 2-5

2. Supply the solder from the upper position of IC leads sliding to the lower position of the IC leads.

(Refer to Fig. 2-6.)

4. When bridge-soldering between terminals and/or the soldering amount are not enough, resolder using a Thintip Soldering Iron. (Refer to Fig. 2-8.)

5. 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.

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.

Solder

3. Absorb the solder left on the lead using the Braided

Shield Wire. (Refer to Fig. 2-7.)

NOTE

Do not absorb the solder to excess.
