2. Installation
a. Using desoldering 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.
b. The "I" mark on the Flat Pack - IC indicates pin 1
(See Fig. S-1-6). Make sure this mark matches the
1 on the CBA when positioning for installation.
Then pre - solder the four corners of the Flat Pack-
IC (See Fig. S-1-7).
c. Solder all pins of the Flat Pack - IC. Make sure that
none of the pins have solder bridges.
