TCS3472 − Soldering & Storage Information

Soldering Information

The FN package has been tested and has 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.
