Recommended Reflow Solder Profiles

The recommended reflow solder profiles for Pb and Pb-free devices are shown below.

Figure 1 shows the recommended solder profile for devices that have Pb-free terminal plating, and where a Pb-free solder 

is used.

Figure 2 shows the recommended solder profile for devices with Pb-free terminal plating used with leaded solder, or for 

devices with leaded terminal plating used with a leaded solder.
