MANUFACTURING INFORMATION

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.
