WITH SOLDERING IRON:
(1) Using desoldering braid, remove the solder from all pins
of the flat pack-IC. When you use solder flux which is
applied to all pins of the flat pack-IC, you can remove it
easily. (Fig.2-3)
Fig.2-3
(2) Lift each lead of the flat pack-IC upward one by one,
using a sharp pin or wire to which solder will not adhere
(iron wire). When heating the pins, use a fine tip
soldering iron or a hot air desoldering machine. (Fig.2-4)
Fig.2-4
(3) Bottom of the flat pack-IC is fixed with glue to the PWB;
when removing entire flat pack-IC, first apply soldering
iron to center of the flat pack-IC and heat up. Then
remove (glue will be melted). (Fig.2-6)
(4) Release the flat pack-IC from the PWB using tweezers.

WITH IRON WIRE:
(1) Using desoldering braid, remove the solder from all pins
of the flat pack-IC. When you use solder flux which is
applied to all pins of the flat pack-IC, you can remove it
easily. (Fig.2-3)
(2) Affix the wire to a workbench or solid mounting point, as
shown in Fig.2-5.
(3) While heating the pins using a fine tip soldering iron or
hot air blower, pull up the wire as the solder melts so as
to lift the IC leads from the PWB contact pads as shown
in Fig.2-5.
(4) Bottom of the flat pack-IC is fixed with glue to the PWB;
when removing entire flat pack-IC, first apply soldering
iron to center of the flat pack-IC and heat up. Then
remove (glue will be melted). (Fig.2-6)
(5) Release the flat pack-IC from the PWB using tweezers.
(Fig.2-6)
NOTE:
When using a soldering iron, care must be taken to ensure
that the flat pack-IC is not being held by glue. When the flat
pack-IC is removed from the PWB, handle it gently because
it may be damaged if force is applied.
