TSL2521 − Soldering & Storage Information

Soldering Information

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.

Solder Reflow Profile

Note(s):

1. Tolerance for peak profile temperature (TP) is defined as a supplier minimum and a user maximum.
