2.2.2 Soldering IC Socket
After fastening, solder the IC socket for a FP-144 package to the user system.
CAUTION
Be sure to completely solder the leads so that the solder
slops gently over the leads and forms solder fillets. (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 a FP-144 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.
