9. The high-voltage components of the system should be equipped with electrical interlocks to
protect personnel from injury. DO NOT ATTEMPT TO DEFEAT, OVERRIDE, OR BYPASS
THESE PROTECTIVE DEVICES!
10. Never leave loose ends on high-voltage connections.
11. Observe the following warning if the system employs Radio Frequency (RF) power.
DANGER
RF radiation—even at modest power levels—can cause serious injury. If any of the RF
components (e.g., the RF power supply, the RF matching network, or the RF electrodes or
shielding inside the product chamber) are moved or changed in any way, the RF energy may
be radiated outside the equipment. Monitor the equipment to assure that external RF
radiation is below the levels prescribed by any and all applicable safety codes.

FC-3800 F & I Guide iv 0101-8604-0, Rev. F
Special Amendment for United Kingdom Users
All Electrical Power Sources: Safety Precautions
This component is designed to be used in an extra-high-voltage system. Only authorized personnel
should be permitted to carry out work on this system.
Prior to any servicing, grounding hooks should be used to short out all high-voltage parts and
conductors in both the vacuum system and the high-voltage power supply. Screens protecting extra-
high-voltage conductors should be removed only if appropriate action has been taken to ensure that
extra-high-voltage conductors are dead and cannot be reenergized inadvertently.
In addition, all personnel should be aware of:
1. The Electricity (Factories Act) Special Regulations (1908 and 1944), in particular, Regulations
18(d) and 28 of the 1980 Regulations, as amended; and
2. The employer’s responsibility to set up suitable systems to safeguard the health and safety of
employees, according to the Health & Safety at Work etc. Act (1974).

FC-3800 F & I Guide vi 0101-8604-0, Rev. F
HEALTH HAZARD
The condensates deposited on the tank walls of a vacuum system are generally in the form of
extremely fine particles. The nature, as well as the form, of the materials poses the following
potential health hazards:
a) Inhaling fine particles (powder) may cause damage to the lungs. To help prevent this, wear a
protective respirator mask with fine filter that has been approved by the National Institute for
Occupational Safety and Health (NIOSH) and the federal Mine Safety and Health
Administration (MSHA).
b) Some substances are toxic and inhaling them should be avoided. Take steps to ascertain
whether or not the material being deposited is a known toxic substance. Refer to the Material
Safety Data Sheet(s) covering the evaporant(s) in question.
c) Certain powders (titanium, for instance) can cause flash fires when exposed to oxygen or
other oxidizers. Therefore, when opening the chamber door after a deposition cycle, exercise
extreme caution and allow time for the coating surface to oxidize. Breakage of some of the
more reactive condensates may be hazardous, even when the above precautions are observed.
In this situation, fire-protective clothing should be worn.
d) Certain powders (platinum, for instance) are known to catalyze methyl alcohol vapors upon
contact, generating heat in the process and possibly causing a fire to erupt. Therefore, never
use methyl alcohol to wipe down or clean any internal tank surfaces of a vacuum system.
Use isopropyl alcohol (IPA), instead. Dispose of all IPA-exposed lint-free paper/cloth into a
fireproof container, while ensuring all proper safety procedures and precautions are being
followed.

earth ground is provided for the system and the power supply. This ground must provide
a low-impedance path for radio frequency (RF) and direct current (DC) electricity. This
ground must not be connected to that of any other system or equipment.
Figure 2-1 illustrates the required facility and system grounding requirements. Two 8-foot
(2.44-meter) copper-clad steel rods of ¾ inch (20 mm) diameter should be driven into the
earth as near as possible to the vacuum cubicle. These rods should be approximately 6
feet (1.85 meters) apart. After they are driven into the ground, the resistance between
them should be measured with an accurate volt-ohm meter. The maximum allowable
resistance is 3 ohms. If the resistance is greater than that value, pouring salt water or
copper sulfate down the sides of the rods may lower the resistance to the required level.
To ensure a low-impedance path to ground, the rods must be connected to each other
and to the vacuum chamber by a length of 3-inch (76-mm) wide copper strap. For runs of
less than 60 feet (18.3 meters), this strap should be 0.035 to 0.050 inches (0.9–1.3 mm)
thick. For runs longer than 60 feet, consult Temescal for specifications. The strapping
should be silver-soldered to one of the rods and secured to the other mechanically, so
that the grounding strap can be disconnected later to allow retesting of the resistance
between the rods. The other end of the grounding strap should be connected with a
grounding lug or bolt to the evaporation system’s central grounding point, an area of
clean bare metal on the vacuum cubicle wall or frame.
If the equipment is to be installed on the upper floors of a building, the system can be
grounded by connecting the vacuum chamber to the steel structure of the building. This
connection should also be made with 3-inch (76-mm) copper strapping of the gauge
specified above. Figure 2-1 also shows this alternative method.
CAUTION
Do not use braided wire for any ground connections.
CAUTION
Do not rely on water pipes to establish the system ground
connection. Multiple plumbing joints, each with tape and/or
sealing compounds, make such a ground unreliable.

2.5.2 Low-Impedance Ground for the E-Beam Power Supply
Figure 2-2 illustrates the grounding requirements for the Simba 2 power supply. A length
of 3-in.-wide copper strap must connect the Simba 2 power module to the system’s
central grounding point. In addition, the shield of the high-voltage cable running between
the gun interface and the filament transformer must be connected to the vacuum
cubicle’s central grounding point, as shown in Figure 2-2. The gun interface chassis must
also be connected to the system’s low-impedance ground. If the gun interface is mounted
in the optional control console, the gun interface can be grounded in one of two ways. A
length of copper strap can connect its grounding lug directly to the system’s central
grounding point, as indicated in Figure 2-2. Alternatively, a short length of copper strap
can be used to connect grounding lug on the gun interface to the grounding bracket on
the Simba 2 power module, as indicated in Figure 3-9. If the gun interface is mounted in
the operator station, its low-impedance ground is provided by the length of copper strap
that connects the operator station to the system’s central grounding point.
Figure 2-2 Vacuum Cubicle Grounding for Simba 2 Power Supply
On systems with CV-6SLX and CV-12SLX power supplies, the power module is mounted
in the operator station, so its low-impedance ground is likewise provided by the length of
copper strap that connects the operator station to the system’s central grounding point.
On these power supplies, the high-voltage cable connecting the power module to the
filament power supply (FPS) is adequately grounded when the coaxial cable is plugged
into the FPS. For an illustration of the low-impedance grounding requirements on
systems with a CV-6SLX and a CV-6SLX power supply, see Figure 2-3.

2.5.3 Electron Beam Source Ground
To ensure a good ground between the electron beam source and the vacuum cubicle, the
following conditions must be met:
 The base of the source and the surface on which it is mounted (usually the upper
surface of the source tray) must be clean and free of evaporated material.
 The mounting surface must be made of nonmagnetic material.
 The source must be securely bolted to the mounting surface.
2.5.4 Grounding Hooks
One grounding hook is provided at each of the following locations of the system where
high voltage may be present:
 Inside the vacuum cubicle
 On systems with CV-6SLX or CV-12SLX power supplies, inside the right-hand
door of the operator station
 On systems with Simba 2 power supplies, on the side of the Simba 2 power
module
