The RoHS compliant components are
manufactured using Sn/Ag solder as
compared to Sn/Pb solder. The terminations
on the RoHS compliant device are Sn plated
as compared to Sn/Pb plated on the nonRoHS complaint devices. All products that
are RoHS compliant will ship with a lead
free logo on the packaging label and a
designation of the solder used in the
components construction.

Solder reflow
• Recommended reflow methods: IR, vapor phase oven, hot air oven.
• Devices are not designed to be wave soldered to the bottom side of the
board.
• Gluing the devices is not recommended.
• Recommended maximum paste thickness is 0.25 mm (.010 inch).
• Devices can be cleaned using standard industry methods and solvents.
Note:
• If reflow temperatures exceed the recommended profile, devices may not
meet the performance requirements.
Rework
• A device should not be reworked.
