9. Solder Profiles

Composition of the solder ball: Sn 95.5%, Ag 4.0%, Cu 0.5%

Typical Lead-Free Re-flow Solder Profile

Key features of the profile:

Initial Ramp = 1-2.5°C/sec to 175°C±25°C equilibrium

Equilibrium time = 60 to 180 seconds

8


Ramp to Maximum temperature (250°C) = 3°C/sec max.

Time above liquidus temperature (217°C): 45-90 seconds

Device absolute maximum reflow temperature: 260°C

Devices will withstand the specified profile. Lead-free devices will withstand up to three

reflows to a maximum temperature of 260°C.

Notes：They need to be baked prior to mounting.

10. Guide for Antenna Radiation

In order to achieve longest communication range, please keep the area surrounding

antenna free of grounding or metal housing.
