Solder reflow

Due to “Lead Free” nature, Temperature
and Dwell time for the soldering zone is
higher than those for Non-compliant parts.
This may cause damage to other
components.

Recommended max solder paste thickness
> 0.25mm.

Devices can be cleaned using standard
methods and aqueous solvent.

Rework should utilize standard industry
practices. These changes should apply to
all notes for each case size.

Storage Environment : < 30ºC / 60%RH
Caution:

If reflow temperatures exceed the
recommended profile, devices may not
meet the performance requirements.

Devices are not designed to be wave
soldered to the bottom side of the board.

Solder reflow

Due to “Lead Free” nature, Temperature
and Dwell time for the soldering zone is
higher than those for Non-compliant
parts. This may cause damage to other
components.

Recommended max solder paste
thickness > 0.25mm.

Devices can be cleaned using standard
methods and aqueous solvent.

Rework should utilize standard industry
practices. These changes should apply to
all notes for each case size.

Storage Environment : < 30ºC / 60%RH
Caution:

If reflow temperatures exceed the
recommended profile, devices may not
meet the performance requirements.

Devices are not designed to be wave
soldered to the bottom side of the board.
