MANUFACTURING INFORMATION

The package has 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.
