How to Remove / Install Flat Pack-IC
With Hot-Air Flat Pack-IC De=soldering Machine
1. Prepare the hot-air flat pack-IC de-soldering machine, then apply hot air to the Flat Pack-IC (about 5 to 6 seconds).
2. Remove the flat pack-IC with tweezers while applying the hot air.
3. Bottom of the flat pack-IC is fixed with glue to the CBA; 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).
4. Release the flat pack-IC from the CBA using tweezers.
The Flat Pack-IC shape may differ by models. Use an appropriate hot-air flat pack-IC de-soldering machine, whose shape matches that of the Flat Pack-IC.
2. Do not supply hot air to the chip parts around the flat pack-IC for over 6 seconds because damage to the chip parts may occur. Put masking tape around the flat pack-IC to protect other parts from damage.
3. The flat pack-IC on the CBA is affixed with glue, so be careful not to break or damage the foil of each pin or the solder lands under the IC when removing it.
With Soldering Iron
1. Using de=soldering 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.
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 de=soldering machine.
3. Bottom of the flat pack-IC is fixed with glue to the CBA; 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).
4. Release the flat pack-IC from the CBA using tweezers.
With Iron Wire
1. Using de=soldering 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.
2. Affix the wire to a workbench or solid mounting point.
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 CBA contact pads.
4. Bottom of the flat pack-IC is fixed with glue to the CBA; 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).
5. Release the flat pack-IC from the CBA using tweezers.
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 CBA, handle it gently because it may be damaged if force is applied.
Installation
1. Using de-soldering braid, remove the solder from the foil of each pin of the flat pack-IC on the CBA so you can install a replacement flat pack-IC more easily.
2. The “I” mark on the flat pack-IC indicates pin 1.  Be sure this mark matches the
pin 1 on the PCB when positioning for installation.  Then pre-solder the four corners of the flat pack-IC.
3. Solder all pins of the flat pack-IC. Be sure that none of the pins have solder bridges.
