Data Sheet
Description
The HSDL-3200 is a new
generation of low-cost Infrared
(IR) transceiver module from
Agilent Technologies. It features
the smallest footprint in the
industry at 2.5 H x 8.0 W x 3.0 D
mm. The supply voltage can
range from 2.7 V to 3.6 V. The

The HSDL-3200 meets the link
distance of 20 cm to other low
power devices, and 30 cm to
standard 1 meter IrDA devices.

The reflow profile is a straightline representation of a nominal
temperature profile for a
convective reflow solder
process. The temperature profile
is divided into four process
zones, each with different
DT/Dtime temperature change
rates. The DT/Dtime rates are
detailed in the above table. The
temperatures are measured at
the component to printed circuit
board connections.
In process zone P1, the PC
board and HSDL-3200
castellation I/O pins are heated
to a temperature of 160°C to
activate the flux in the solder
paste. The temperature ramp up
rate, R1, is limited to 4°C per
second to allow for even heating
of both the PC board and HSDL3200 castellation I/O pins.

Process zone P2 should be of
sufficient time duration (60 to
120 seconds) to dry the solder
paste. The temperature is raised
to a level just below the liquidus
point of the solder, usually
200°C (392°F).
Process zone P3 is the solder
reflow zone. In zone P3, the
temperature is quickly raised
above the liquidus point of
solder to 255°C (491°F) for
optimum results. The dwell time
above the liquidus point of
solder should be between 20 and
60 seconds. It usually takes
about 20 seconds to assure
proper coalescing of the solder
balls into liquid solder and the
formation of good solder
connections. Beyond a dwell
time of 60 seconds, the
intermetallic growth within the

solder connections becomes
excessive, resulting in the
formation of weak and
unreliable connections. The
temperature is then rapidly
reduced to a point below the
solidus temperature of the
solder, usually 200°C (392° F), to
allow the solder within the
connections to freeze solid.
Process zone P4 is the cool
down after solder freeze. The
cool down rate, R5, from the
liquidus point of the solder to
25°C (77°F) should not exceed
6°C per second maximum. This
limitation is necessary to allow
the PC board and HSDL-3200
castellation I/O pins to change
dimensions evenly, putting
minimal stresses on the HSDL3200 transceiver.
Moisture Proof Packaging
The HSDL-3200 is shipped in
moisture proof packaging. Once
opened, moisture absorption
begins.

Recommended Metal Solder Stencil
Aperture
It is recommended that only
0.127 mm (0.005 inches) or 0.11
mm (0.004 inches) thick stencil
be used for solder paste
printing. This is to ensure
adequate printed solder paste
volume and no shorting. The
following combination of metal
stencil aperture and metal
stencil thickness should be used:
w, the width of aperture is fixed
at 0.55 mm (0.022 inches).
Aperture opening for shield pad
is as per land pattern.
Adjacent Land Keepout and Solder

Adjacent land keep-out is the

Recommended Solder Paste/Cream
Volume for Castellation Joints
Based on calculation and
experiment, the printed solder
paste volume required per
castellation pad is 0.22 cubic
mm (based on either no-clean or
aqueous solder cream types with
typically 60% to 65% solid
content by volume). Using the
recommended stencil will result
in this volume of solder paste.
Pick and Place Misalignment
Tolerance and Self-Alignment after
Solder Reflow
If the printed solder paste
volume is adequate, the HSDL3200 will self-align after solder
reflow. Units should be properly
reflowed in IR/Hot Air
convection oven using the
recommended reflow profile.
The direction of board travel
does not matter.

Tolerance for X-Axis Alignment of
Castellation
Misalignment of castellation to
the land pad should not exceed
0.2 mm (0.008 in.), or about one
half the width of the castellation
during placement of the unit.
The castellations will self-align
to the pads during solder reflow.
Tolerance for Rotational (Theta)
Misalignment
Units when mounted should not
be rotated more than ± 3 degrees
with reference to center X-Y as
shown in the recommended land
pattern. Units with rotational
misalignment of more than
± 3 degrees will not completely
self-align after reflow. Units with
less than a ± 3 degree
misalignment will self-align after
solder reflow.
Y-Axis Misalignment of Castellation
In the Y direction, the
HSDL-3200 does not self-align
after solder reflow. It is
recommended that it be placed
in line with the fiducial mark
(mid-length of land pad). This
will enable sufficient land length
(minimum of 1/2 land length) to
form a good joint. See the
drawing below.

Marking Information
The unit is marked with a letter
“B” and “YWWLL” for front
options on the shield. Y is the
year, WW is the workweek, and
LL is the Lot information.
Window Design
To insure IrDA compliance, there
are some constraints on the
height and width of the optical
window. The minimum
dimensions ensure that the IrDA
cone angles are met, and there is
no vignetting, and the maximum
dimensions ensure that the effects
of stray light are minimized. The
minimum size corresponds to a
cone angle of 30 degrees, the
maximum to a cone angle of 60
degrees.

Shape of the Window
From an optics standpoint, the
window should be flat. This
ensures that the window will not
alter either the radiation pattern
of the LED, or the receive
pattern of the photodiode.
Flat Window
If the window must be curved
for mechanical design reasons,
place a curve on the back side of
the window that has the same
radius as the front side. While
this will not completely
eliminate the lens effect of the
front curved surface, it will
reduce the effects. The amount
of change in the radiation
pattern is dependent upon the
material chosen for the window,
the radius of the front and back
curves, and the distance from
the back surface to the
transceiver. Once these items
are known, a lens design can be
made which will eliminate the
effect of the front surface curve.
Curved Front, Flat Back
The following drawings show the
effects of a curved window on
the radiation pattern. In all
cases, the center thickness of the
window is 1.5 mm, the window
is made of polycarbonate plastic,
and the distance from the
transceiver to the back surface
of the window is 3 mm.

Test Methods
Background Light and
Electromagnetic Field
There are four ambient
interference conditions in which
the receiver is to operate
correctly. The conditions are to be
applied separately:
1. Electromagnetic field:
3 V/m maximum (please refer
to IEC 801-3, severity level 3
for details).
2. Sunlight:
10 kilolux maximum at the
optical port. This is simulated
with an IR source having a
peak wavelength within the
range of 850 nm to 900 nm and
a spectral width of less than
50 nm biased to provide 490
µW/cm2 (with no modulation)
at the optical port. The light
source faces the optical port.

This simulates sunlight within
the IrDA spectral range. The
effect of longer wavelength
radiation is covered by the
incandescent condition.
3. Incandescent Lighting:
1000 lux maximum. This is
produced with general service,
tungsten-filament, gas-filled,
inside frosted lamps in the 60
Watt to 100 Watt range to
generate 1000 lux over the
horizontal surface on which the
equipment under test rests.
The light sources are above the
test area. The source is
expected to have a filament
temperature in the 2700 to
3050 Kelvin range and a
spectral peak in the 850 to
1050 nm range.
4. Fluorescent Lighting:
1000 lux maximum. This is
simulated with an IR source
having a peak wavelength
within the range of 850 nm to
900 nm and a spectral width of
less than 50 nm biased and
modulated to provide an
optical square wave signal
(0 µW/cm2 minimum and
0.3 µW/cm2 peak amplitude
with 10% to 90% rise and fall
times less than or equal to
100 ns) over the horizontal
surface on which the
equipment under test rests.
The light sources are above the
test area. The frequency of the
optical signal is swept over the
frequency range from 20 kHz to
200 kHz.
Due to the variety of
fluorescent lamps and the
range of IR emissions, this
condition is not expected to
cover all circumstances. It will
provide a common floor for
IrDA operation.
