Safety and Handling
Follow recommended soldering conditions: reflow temperature 245±5°C for 20-30 seconds, maximum 260°C.
Avoid physical shocks and excessive force during handling to prevent damage.
Ensure proper soldering land pattern: generally 0.7 to 0.8 times (W) of chip width for flow soldering, and 1.0 to 1.3 times for reflow soldering.
Consult the datasheet for detailed technical specifications and handling precautions.
Design and specifications are subject to change without notice. Please review the datasheet for the most current information. For more details, search the internet for the part number ERJ-1GEF1242C.
