with PROXIMITY SENSING
TAOS110A − MARCH 2011
MANUFACTURING INFORMATION
The FN package has been tested and has demonstrated an ability to be reflow soldered to a PCB substrate.
The solder reflow profile describes the expected maximum heat exposure of components during the solder
reflow process of product on a PCB. Temperature is measured on top of component. The components should
be limited to a maximum of three passes through this solder reflow profile.
