9 reflow profile the reflow profile is a straight line representation of a nominal temperature profile for a convec- tive reflow solder process. the temperature profile is divided into four process zones, each with different d t/ d time temperature change rates. the d t/ d 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-3000 castellation i/o pins are heated to a temperature of 125 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 hsdl-3000 castellation i/o pins. process zone symbol d t maximum d t/ d time heat up p1, r1 25 c to 125 c4 c/s solder paste dry p2, r2 125 c to 170 c 0.5 c/s solder reflow p3, r3 170 c to 230 c (245 c max.) 4 c/s p3, r4 230 c to 170 cC4 c/s cool down p4, r5 170 c to 25 cC3 c/s 0 t-time (seconds) t ?temperature ?(?) 200 170 125 100 50 50 150 100 200 250 300 150 183 230 p1 heat up p2 solder paste dry p3 solder reflow p4 cool down 25 r1 r2 r3 r4 r5 90 sec. max. above 183? max. 245? 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 170 c (338 f). process zone p3 is the solder reflow zone. in zone p3, the temperature is quickly raised above the liquidus point of solder to 230 c (446 f) 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 connec- tions becomes excessive, result- ing in the formation of weak and unreliable connections. the temperature is then rapidly reduced to a point below the soli- dus temperature of the solder, usually 170 c (338 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 C3 c per second maximum. this limitation is necessary to allow the pc board and hsdl-3000 castellation i/o pins to change dimensions evenly, putting mini- mal stresses on the hsdl-3000 transceiver.

13 appendix b: hsdl-3000#007/#017 C recommended optical port design to insure irda compliance, some constraints on the height and width of the window exist. the minimum dimensions ensure that the irda cone angles are met without vignetting. the maxi- mum dimensions minimize the effects of stray light. the mini- mum size corresponds to a cone angle of 30 degrees, the maxi- mum, to a cone angle of 60 degrees. x is the width of the window, y is the height of the window, and z is the distance from the hsdl-3000 to the back of the window. the distance from the center of the led lens to the center of the photodiode lens is 5.80 mm. the equations for the size of the window are as follows: x = 5.80 +2(z + d) tan q y = 2(z + d) tan q where q is the required half angle for viewing. for the irda mini- mum, it is 15 degrees, for the irda maximum it is 30 degrees. (d is the depth of the led image inside the part, 3.2 mm from the tx lens vertex). these equations result in the following tables and graphs: z x y

15 flat window (first choice) curved front, flat back (do not use) curved front and back (second choice) shape of the window from an optics standpoint, the window should be flat. this en- sures 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 win- dow is 1.5 mm, the window is made of polycarbonate plastic, and the distance from the trans- ceiver to the back surface of the window is 3 mm.
www.semiconductor.agilent.com data subject to change. copyright ? 2001 agilent technologies, inc. june 28, 2001 5988-3265en test methods background light and electro- magnetic field there are four ambient interfer- ence 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 61000-4-3 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 m w/cm 2 (with no modula- tion) at the optical port. the light source faces the optical port. this simulates sunlight within the irda spectral range. the effect of longer wavelength radation is covered by the in- candescent 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 spec- tral 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 m w/cm 2 minimum and 0.3 m w/cm 2 peak amplitude with 10% to 90% rise and fall times less than or equal to 100 ns) over the horizontal surface on which the equip- ment 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 fluores- cent lamps and the range of ir emissions, this condition is not expected to cover all circum- stances. it will provide a common floor for irda operation. 16
