[. . . ] 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. 4-3. ) 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. Tweezers Fig. Heat the IC leads using a blower type IC desoldering machine. 4-2. ) NOTE Do not rotate or move the IC back and forth , until IC can move back and forth easily after desoldering the leads completely. IC Fig. Absorb the solder left on the pattern using the Braided Shield Wire. 4-4. ) NOTE Blower type IC desoldering machine Do not move the Braided Shield Wire in the vertical direction towards the IC pattern. Braided Shield Wire Soldering Iron IC Fig. 4-4 B4-1 MD20F51/MD20F51C DISASSEMBLY INSTRUCTIONS 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. When bridge-soldering between terminals and/or the soldering amount are not enough, resolder using a Thintip Soldering Iron. 4-8. ) IC Thin-tip Soldering Iron Soldering Iron Fig. 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, always be sure to replace the IC in this case. Solder temporarily Solder temporarily Fig. Supply the solder from the upper position of IC leads sliding to the lower position of the IC leads. 4-6. ) Solder Soldering Iron IC Supply soldering from upper position to lower position Fig. Absorb the solder left on the lead using the Braided Shield Wire. 4-7. ) NOTE Do not absorb the solder to excess.
