Important Information for Soldering
1. Soldering Position
2. Solder Temperature and Soldering Time
Temperature : 260C or less
Time : within 3 seconds
Note) Avoid using reflow soldering methods.
3. Other Issues
1) Soldering should not create excessive thermal or mechanical stress on the case package or leads.
Excessive stress may cause changes in the shape or characteristics of the package or leads.
2) Be careful not to allow solder, flux, solvents, etc. to remain on the case package.
Doing so may cause problems related to transmission characteristics, etc.
Important Information Related to Power Source Voltage
In order to stabilize the power line, use a decoupling capacitor of
approximately 0.1
F between V
CC
and the GND line near the device .
A : Make sure the distance is 0.1 mm or more.
