AS7221 − Soldering & Storage Information

Solder Reflow Profile

The module 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

components should be limited to a maximum of three passes

through this solder reflow profile.
