Recommended Metal solder Stencil Aperture It is recommended that only a 0.152 mm (0.006 inch) or a 0.127 mm (0.005 inch) thick stencil be used for solder paste printing. This is to ensure adequate printed solder paste volume and no shorting. See Table 1 below the drawing for combinations of metal stencil aperture and metal stencil thickness that should be used. Aperture opening for shield pad is 3.05 mm x 1.1 mm as per land pattern. Adjacent Land Keepout and Solder Mask Areas Adjacent land keepout is the maximum space occupied by the unit relative to the land pattern. There should be no other SMD components within this area. The mini- mum solder resist strip width required to avoid solder ...

Appendix B: PCB Layout Suggestion The effects of EMI and power supply noise can poten- tially reduce the sensitivity of the receiver, resulting in re- duced link distance. The PCB layout played an important role to obtain a good PSRR and EM immunity resulting in good electrical performance. Things to note: 1. The ground plane should be continuous under the part, but should not extend under the shield trace. 2. The shield trace is a wide, low inductance trace back to the system ground. CX1, CX2, CX3, CX4 and CX5 are optional supply filter capacitors; they may be left out if a clean power supply is used. 3. VLED can be connected to ...

NOISE SOURCES TO BE PLACED AS FAR AWAY FROM THE TRANSCEIVER AS POSSIBLE CX1 R 1 CX2 LAYER 3 BOTTOM LAYER (GND) The area underneath the module at the second layer, and 3 cm in all directions around the module, is defined as the critical ground plane zone. The ground plane should be maximized in this zone. Refer to application note AN1114 or the Lite-On IrDA Data Link Design Guide for details. The layout below is based on a 2-layer PCB.

Window Material Almost any plastic material will work as a window mate- rial. Polycarbonate is recommended. The surface finish of the plastic should be smooth, without any texture. An IR filter dye may be used in the window to make it look black to the eye, but the total optical loss of the window should be 10% or less for best optical performance. Light loss should be measured at 875 nm. The recommended plastic materials for use as a cosmetic window are avail- able from General Electric Plastics. Recommended Plastic Materials: Light Material # Transmission Haze Lexan 141 88% 1% Lexan 920A 85% 1% Lexan 940A 85% 1% Note: 920A and 940A are more flame retardant than 141.
