STARTS
You will install IC sockets in the fol
lowing steps. Be sure the socket pins
are straight and then install the socket
on the circuit board so the index mark
on the board can still be seen. Turn the
circuit board over, be sure there is a pin
in each of the holes, and then solder the
pins to the foil.

( ) Carefully check each socket for
solder bridges between pins. If a
solder bridge has occurred, hold
the circuit board foil-side-down
as shown, and hold the soldering
iron tip between the two points
that are bridged. The solder will
flow down the soldering iron tip.

) Pl: 3-pin plug. Start the shorter
plug pins into the circuit board
holes as shown and push the plug
down tight against the circuit
board. Then solder the pins to the
foil and cut off any excess pin
lengths.
Ul: 7805 integrated circuit
(#442-54). First bend the leads
straight down as shown. Then in
sert the leads into the circuit
board holes. Be sure the IC is tight
against the circuit board. Then
solder the leads to the foil and cut
off any excess lead lengths.
