TAOS029L − OCTOBER 2007
The D and T packages have been tested and have demonstrated an ability to be reflow soldered to a PCB
substrate. The process, equipment, and materials used in these test are detailed below.
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.
