The Plastic Small Outline IC package (D) 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 component should
be limited to a maximum of three passes through this solder reflow profile.
