connections while applying pressure down on the board.
remove any gaps that may be present between the IC sockets and
the PC board.
Finally, solder the remaining pins of the IC
sockets.
DIP HEADER SOLDERING
When making jumper connections on a DIP header, solder resistor
or capacitor lead snippings between the leads to be connected.
When more than two pins are to be connected together, bend a
single wire so that it routes to each pin, and solder each pin
once.
Insert the- header in an IC socket on a PC board to hold it
during soldering.
will melt the plastic of the header.
jumpers on a header, make sure that no unintended connections are
made by carefully routing the jumpers, or by insulating each
jumper with some wire insulation.
RESISTOR AND CAPACITOR INSTALLATION
To install resistors or capacitors, first make right angle bends
in the leads to fit the PC board hole spacing.
leads are already appropriately spaced and do not need bending.)
' Then .insert the leads as far as possible through the correct
holes in the PC board and spread the leads slightly on the solder
side of the board to keep the part in place.
resistors or capacitors has been inserted, then solder the leads
on the solder side of the board and snip off the excess leads as
close to the board as possible.

in making jumper connections.
PRINTED CIRCUIT BOARD LAYOUT
The white component layout legend is printed on the component
side of a printed circuit (PC) board.
inserted from this side (component side) and soldered on the
other side (solder side).
identified by two-character codes as marked on the board: a digit
followed by a letter indicating the horizontal and vertical
coordinates of the location.
can be found on styrene pads in positions corresponding to their
intended locations on the PC board.
Pin numbering conventions for the S-100 edge pins are as follows:
When viewing the component side of the board (with the pin edge
facing down), pins 1,2, .... 50 range from left to right.
viewing the soider side of the board, pins 100, 99, ..., 51 range
from left to right.
