Thanks again.

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). (Fig. S-1-6) 4. Release the flat pack-IC from the CBA using tweezers. (Fig. S-1-6) CAUTION: 1. The Flat Pack-IC shape may differ by models.

Put masking tape around the flat pack-IC to protect other parts from damage. (Fig. S-1-2)
