Step 5Insert and Solder Sockets
Next we solder in the sockets to hold the Integrated Circuits.
NOTE
I have decided to use a 16 pin socket for the RS232 chip. There is a good possibility that using a socket instead of soldering the chip directly to the board will create a problem. if you intend to install the LCD add-on kit the chip may stand in the way due to the height increase caused by the socket. Make sure you test for this issue before you decide to use a socket. I do not have the lcd add-on kit so it will pose no problem for me.
Update: Graham Davies of Ecros Tech sent me a complimentary LCD add-on kit after reading this instructable. I have installed it and the socket for the RS232 chip does not get in the way of the the LCD.
1. Place each socket provided in the basic parts kit in the appropriate places on the top of the circuit board.
3. Flip the board over making sure the sockets do not fall out. Place them on a flat surface (the pine board) and make sure they are tight against the circuit board before tacking 2 opposite pins.
4. Check to see that the body of each socket is flush against the board. If not, reheat the tack points while applying slight pressure to the socket until it is snug against the board.
5. Once all the sockets are against the board solder the rest of the pins for each socket as well as the legs of the reset button.
6. Double check that you didn't miss any pins.
7. Follow the same process to install a 16-pin socket for the RS232 chip if you desire. This socket is not included with any of the Ecros kits.
I did not find it necessary to clip the pins after soldering. None of them stuck out enough for me to take notice.

- Make sure to match the notch on the top of the socket with the notch on the silk screen of the PCB. This will ensure proper orientation for the AVR chips when inserted.
