Hi Noriyuki,

I am attaching a beautiful app note regarding the use of via, how it will help for heat dissipation.

Please go through this app note.

Hi Manish,

Based on the description of the app note below, vias should be placed with 1mm spacing. Do this mean that in general TI doesn't recommend to palce vias as the picture below? This is because the space between vias is too small in this example.
