WIRING DIAGRAM MANUAL
C. Tag and identify
wires as they are removed
from connector
or any other electrical
device to facilitate
reinstallation.
4. Printed
Circuit Board
Repair Cautions
A. Repair of printed
circuit board assemblies
by other than
experienced technicians
is not recommended.
Unless a malfunction
can be localized to a particular component,
an entire board should be replaced
to correct a fault.
B. Semiconductor devices
are heat sensitive. Use a suitable heat
dissipater between solder connection
and body of component
when soldering or removing
solder connections.
(1)
All solder and solder
removal tools should
be low wattage (40
watt) and low temperature
(750°
maximum).
Do not overheat
the circuit board lands.
(2) To
avoid heat damage,
remove solder joint
within three seconds
and solder a joint
within two
seconds.
(3) Excessive
pressure from a
solder or solder removal
tool can delaminate
the circuit pads or
runs.
Use
a light touch when
using these devices.
(4) Avoid placing
the hot soldering
iron near components
or printed circuitry
when iron is not in use.
C. Use
only rosin cored solder
material conforming
to Federal Specifications
QQ-S-571, Composition
Sn60. Use rosin
solder flux with an alcohol base. In no
case is acid core solder or acid base flux
to
be used to install electrical components.
D. Do not use ultrasonic equipment, Methyl n-Propyl Ketone or chlorinated hydrocarbon solutions to
clean printed circuit
board assemblies.
E. Steel
wool, steel wire brushes
and abrasives containing
iron or iron
oxide shall not be used
for
mechanical cleaning.
F.
Use care when handling
printed circuit board
assemblies to avoid flexing
and cracking boards
and to
avoid
wire
breakage
at soldered
connections.
G. Special Handling
of Static Sensitive
Devices.
(1) Integrated
circuits and some other components used
on printed circuit boards can be damaged
by static electricity.
(2) Use
precautionary procedures
when touching,
removing or
inserting components
and
assemblies identified as
being electrostatic discharge
sensitive.
(3) Static sensitive
devices are sent from the manufacturer with
conducting material shorting the
leads. Maintain the
short on the device leads and case while
storing or moving components.
(4)
Keep static sensitive
devices in their containers
in the same configuration
as they
were originally
shipped whenever possible.
Place the containers on a grounded metal
plate at any station where
operations are
to be performed.
Do not remove container
cover unless
in a static free area.
(5) Repair
personnel shall ground themselves before
handling any static sensitive device.
(6) Personnel
shall wear a
conductive wrist strap
connected to a ground
having a resistance
of 0.25
to 2 megohms.
(7) Handle
devices only when
necessary, and then
by first grasping the
ceramic body or the
metal
can before
touching any of the
individual leads with
tweezers or other
tools. Do not handle
by
leads
or terminals. Ceramic
packages with
brazed leads require
extra careful handling
to avoid
breaking
off the leads since bending and
twisting can fracture the braze.
(8) Perform
all assembly operations involving static
sensitive devices on a grounded conductive
surface having a resistance
of 100K ohms to 2 megohms/per
square.
(9) Electrically ground all metal cabinets and conductive containers used for storing static sensitive
devices.
(10) Personnel shall wear smocks
made of cotton or antistatic nylon. Do
not use smocks made from
ordinary nylon or other synthetic
materials. Antistatic garments shall be
plainly marked.
(11) All electrical assembly
equipment (soldering
irons and tips,
insulation strippers,
heat guns, etc.)
must be grounded.
All solder
and solder removal
tools and equipment
must also be grounded.
Ionized
air blowers
can
be used to
reduce
charge buildup
in areas
where
grounding
is not
possible
or
desirable.
