soldering amount are not enough, resolder using a

new IC fitting on the printed circuit pattern. Then solder
each lead on the diagonal positions of IC temporarily.
(Refer to Fig. 2-5.)
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.

bending of leads are repaired, the pattern may be
damaged. So, always be sure to replace the IC in this

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.
