Description

The APDS-9005 is a low cost analog-output ambient

light photo sensor in miniature chipLED lead-free surface

mount package. It consists of a photo sensor, whose

spectral response is close to the CIE standard photopic

observer, as show in gure 2. The APDS-9005 is ideal for

applications in which the measurement of ambient light

is used to control display backlighting. Mobile applianc-

es such as the mobile phones and PDAs that draw heavy

current from display backlighting will benet from incor-

porating these photo sensor products in their designs by

reducing power consumption signicantly.

Application Support Information

Moisture Proof Packaging Baking Conditions: All APDS-9005 options are shipped in moisture proof package. Once opened, moisture absorption begins. This part is compliant to JEDEC Level 3. If the parts are not stored in dry conditions, they must be baked before reflow to prevent damage to the parts. Units in A Sealed Mositure-Proof Package Package Temperature Time In Reel 60°C 48 hours In Bulk 100°C 4 hours Baking should only be done once.

Appendix A: SMT Assembly Application Note 1.2 Recommended Metal Solder Stencil Aperture 1.0 Solder Pad, Mask and Metal Stencil Aperture Metal Stencil For Solder Paste Printing Stencil Aperture It is recommended that a 0.11 mm (0.004 inches) thick stencil be used for solder paste printing. Aperture opening for shield pad is 0.4mm x 0.4mm and 0.2mm x 0.4mm (as per land pattern). This is to ensure adequate printed solder paste volume and no shorting. Aperture Opening Land Pattern 0.11 Solder Mask 1.

Appendix B: Optical Window Design for APDS-9005 2.0 Optical Window Dimensions To ensure that the performance of the APDS-9005 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-9005.
PAGE 12
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.
