2.2.2 Soldering IC Socket
After fastening, solder the IC socket for an FP-128 package to the user system. Be sure to
completely solder the leads so that the solder slops gently over the leads and forms solder f illets.
(Use slightly more solder than the MCU.)
2.2.3 Inserting Cable Head
CAUTION
Check the location of pin 1 before inserting.
Align pin 1 on the IC socket for an FP-128 package on the user system with pin 1 on the user
system interface cable head, and insert the user system interface cable head into the IC socket on
the user system, as shown in figure 4.
