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 LED drive current of 25 mA assures that link distances meet the IrDA Data 1.2 (low power) physical layer specification. 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 straight line representation of a nominal temperature profile for a convective reflow solder process. The temperature profile is divided into four process zones, each with different T/time temperature change rates. The T/time 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 125C to activate the flux in the solder paste. The temperature ramp up rate, R1, is limited to 4C per second to allow for even heating of both the PC board and HSDL-3200 castellation I/O pins.
Process zone P2 should be of sufficient time duration (> 60 seconds) to dry the solder paste. The temperature is raised to a level just below the liquidus point of the solder, usually 170C (338F). Process zone P3 is the solder reflow zone. In zone P3, the temperature is quickly raised above the liquidus point of solder to 230C (446F) for optimum results. The dwell time above the liquidus point of solder should be between 15 and 90 seconds. It usually takes about 15 seconds to assure proper coalescing of the solder balls into liquid solder and the formation of good solder connections. Beyond a dwell time of 90 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 170C (338F), 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 25C (77F) should not exceed 3C 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 HSDL-3200 transceiver.

Recommended Metal Solder Stencil Aperture
It is recommended that only 0.152 mm (0.006 inches) or 0.127 mm (0.005 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 Mask Areas
Adjacent land keep-out is the maximum space occupied by the unit relative to the land pattern. There should be no other SMD components within this area. "h" is the minimum solder resist strip width required to avoid solder bridging adjacent pads. It is recommended that two fiducial crosses be placed at midlength of the pads for unit alignment. Note: Wet/Liquid PhotoImageable solder resist/mask is recommended.

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 HSDL-3200 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 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.
Marking Information
The unit is marked with the datecode "YYWW" on the shield. YY is the year, and WW is the workweek.
Allowable Misalignment
Direction x Theta Tolerance 0.2 mm (0.008 inches) 3 degrees
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 (midlength of land pad). This will enable sufficient land length (minimum of 1/2 land length) to form a good joint. See the drawing below.
LENS EDGE
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.

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. The drawing below shows the module positioned in front of a window.

X is the width of the window, Y is the height of the window, and Z is the distance from the HSDL-3200 to the back of the window. The distance from the center of the LED lens to the center of the photodiode lens is 5.1 mm. The equations that determine the size of the window are as follows:

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. 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. 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 W/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 W/cm2 minimum and 0.3 W/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.
