Appendix A: SMT Assembly Application Note 1.3 Adjacent Land Keepout and Solder Mask Areas 1.0 Solder Pad, Mask and Metal Stencil Aperture 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. Metal Stencil For Solder Paste Printing Stencil Aperture Note: Wet/Liquid Photo-Imageable solder resist/mask is recommended.

Appendix B: Optical Window Design for APDS-9007 1.0 Optical Window Dimensions To ensure that the performance of the APDS-9007 will not be affected by improper window design, there are some constraints on the dimensions and design of the window. There is a constraint on the minimum size of the window, which is placed in front of the photo light sensor, so that it will not affect the angular response of the APDS-9007. This minimum dimension that is recommended will ensure at least a ±35° light reception cone.

2.1 Optical Window Material The material of the window is recommended to be polycarbonate. The surface finish of the plastic should be smooth, without any texture. The recommended plastic material for use as a window is available from Bayer AG and Bayer Antwerp N. V. (Europe), Bayer Corp.(USA) and Bayer Polymers Co., Ltd. (Thailand), as shown in Table 2. 12 Table 2. Recommended Plastic Materials Material number Visible light transmission Refractive index Makrolon LQ2647 87% 1.

Appendix C: General Application Guide for APDS-9007 The APDS-9007 is an analog current output ambient light photo sensor whose spectral response is close to the CIE standard photopic observer. APDS-9007 consists of a photodiode and an IC that performs amplification of the photodiode output signal and conversion to a logarithmic output current. APDS-9007 is able to produce a high gain photo current that can be converted to an output voltage via a standard value external load resistor.
