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 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. S-1-3)

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. S-1-4)

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). (Fig. S-1-6)

4. Release the flat pack-IC from the CBA using 

tweezers. (Fig. S-1-6)
