Panel Mounting of
Threaded ST Package
Style
Any standard 3/8 - 32 UNEF-2B
threaded nut and washer can be
used to secure the threaded ST
receptacle to the chassis wall,
provided the overall thickness of
the chassis wall, washer and nut
are less than 5.1 mm (0.2 inch).
Agilent supplies the HFBR-4411
kit which consists of 100 each,
nuts and washers per the figure
below.
When preparing the chassis wall
for panel mounting, use the
mounting template in the figure
below. When tightening the nut,
torque should not exceed 0.8 N-m
(8.0 in-lb). Note that the maxi-
mum nut dimension exceeds the
width of the port package, so
approximately 2 mm of space
between device packages is
required to allow nuts to be
mounted on adjacent ports.
ESD Handling
Precautions
The HFBR-0305 Series products
are MIL-STD 883C Method
3015.4 Class 1 devices. Normal
static precautions should be
taken in handling and assembly
of this component to prevent
damage and/or degradation which
may be induced by electrostatic
discharge (ESD)
Solder Processing
The HFBR-0305 Series products
are compatible with either hand
or wave solder processes. When
soldering, it is advisable to leave
the protective cap on the port to
keep the optics clean. Good
system performance requires
clean port optics and cable
ferrules to avoid obstructing the
optical path. Clean compressed
air is often sufficient to remove
particles of dirt; methanol on a
cotton swab also works well.
Wash Processing -
Chemical Resistance
The HFBR-0305 Series package
is compatible with the following
chemicals for cleaning and
degreasing:
- Aqueous Wash
- Naptha
- Alcohol (methyl, isopropyl,
isobutyl)
- Aliphatics (hexane, heptane)
The following chemicals are not
recommended as they will
damage the package: Partially
halogenated hydrocarbons such
as 1,1,1 Trichloroethane, Ketones
such as MEK, Acetone, Chloro-
form, Ethyl Acetate, Methylene
Dichloride and N-methylpyroldone.
Flame Resistance
The HFBR-0305 Series package
is made with UL V-0 flame
retardant plastic material.
Electrostatic Discharge
(ESD)
Static discharges can occur to the
exterior of the equipment chassis
containing the HFBR-0305 Series
parts. To the extent that their
connector receptacles are
exposed to the outside of the
equipment chassis, they may be
subject to whatever ESD system
level test criteria that the
equipment is intended to meet.
Radiated Susceptibility
Equipment utilizing these
products will be subject to EMI
fields in some environments.
These HFBR-0305 Series prod-
ucts are expected to withstand
fields of up to 10 volts per meter,
when tested on a circuit card in
free space without an equipment
chassis, with no measurable
effect on their performance. A
suggested test method is based
on the equipment procedure
specified in IEC 801-3.
