Seating The Microcontroller Into A Socket - Progress Direct Systems Volt Tattler 2 Owner's Manual

Seating the Microcontroller into a Socket

If you are using a socket perform the pin straightening exercise previously discussed. Rest the controller
in the socket in the proper orientation. Check that all of the pins are properly resting in each of their
receptacles in the socket. Any pins outside the socket will not make contract and may cause the Volt
Tattler 2 to fail. Pins can also become trapped under the chip. These must be straightened before
pressing the chip into the socket. Once all of the pins have been checked and are in the sockets, press
down and the chip, slowly increasing pressure until the chip lowers in. It should "bottom out" on the
socket.
In the above picture the builder is headed for trouble. Pin 7 of the chip is not pointing down into the
socket but tucked a bit back under the chip. When this builder pushes down on the chip to seat it into
the socket, pin-7 will fold under the chip and not connect. This may cause issues even though the chip
seemed to seat solidly. Check each pin for proper position before attempting to seat the chip into the
socket.
