Note:
If you do not fill with solder and directly cut the IC lead with the cutter, stress may build up directly in
the P.C.board’s pattern. If you do not fill with large quantities of solder as in step 1 the P.C.board
pattern may be removed.
2. Using a cutter, cut the lead at the source. (Cut the contents with the
cutter lightly 5 or 6 times.)
3. Remove when the solder melts. (Remove the lead at the same time.)
After removing the Flat IC and when attaching the new IC, remove any of the excess solder on the
land using the soldering wire, etc. If the excess solder is not removed from the land, the IC will slip
and not be attached properly.
