Soldering The Ic - Progress Direct Systems Volt Tattler 2 Owner's Manual

The following picture is NOT of the pin 1 end of the microcontroller. There is a small circle which is NOT
the pin-1 end of the chip. But the notch marks the end of pin 1.
Carefully aligning the pins can prevent bending a pin off to the side or underneath the chip.
If you are using a socket be sure that all of the pins are inserted into the pin sockets and not on the side
of the socket or underneath the chip. Proceed to "Seating the Microcontroller into a Socket" section
later.

Soldering the IC

If you are soldering the chip in directly be sure that all of the pins are through the board and ready to be
soldered to the pads on the back of the board (the non-component side). Once all pins are seen through
the PC board, use a piece of cellophane tape to temporarily secure the chip for soldering.
