Electrostatic Sensitive Devices (ESDS) Protection
D.
MOS Device Protection
MOS (Metal Oxide Semiconductor) devices are used in this equipment. While the
attributes of MOS type devices are many, characteristics make them susceptible
to damage by electrostatic or high voltage charges. Therefore, special precautions
must be taken during repair procedures to prevent damaging the device. The fol-
lowing precautions are recommended for MOS circuits, and are especially impor-
tant in low humidity or dry conditions.

6.
When repairing circuits, carefully observe lead dress and
component orientation. Keep leads as short as possible and
observe correct repair techniques.
7.
There are certain soldering considerations with surface
mount components. The soldering iron tip should not touch
the ceramic component body. The iron should be applied
only to the termination-solder filet.
8.
Observe cable routing throughout instrument assembly, pri-
or to disassembly, to enable a proper reinstallation of ca-
bling during reassembly procedures.
CAUTION
THIS EQUIPMENT CONTAINS ELECTRO-
STATIC DISCHARGE SENSITIVE (ESDS) DE-
VICES. EQUIPMENT MODULES AND ESDS
DEVICES MUST BE HANDLED IN ACCOR-
DANCE WITH SPECIAL ESDS HANDLING
PROCEDURES.
1.
Always discharge static before handling devices by touching
something that is grounded.
2.
Use a wrist strap grounded through a 1MΩ resistor.
3.
Do not slide anything on the bench. Pick it up and set it down
instead.
4.
Keep all parts in protective cartons until ready to insert into
the board.
5.
Never touch the device leads or the circuit paths during as-
sembly.
6.
Use a grounded tip, low wattage soldering station.
7.
Keep the humidity in the work environment as high as feasi-
bly possible.
8.
Use grounded mats on the work station unless table tops are
made of approved antistatic material.
9.
Do not use synthetic carpet on the floor of the shop. If a shop
is carpeted, ensure that a grounded mat is placed at each
workstation.
10.
Keep common plastics out of the work area.
