#103434 - Thermal relief in PCB's
Responding to: Kai Klaas's previous message
Thank you Kai . I will implement what you have said and get back to you for any clarifications needed.

I would also like to know about the use of Thermal relief in PCB's.
should i use thermal relief when i connect the ground pin of components to the solid ground plane (in bottom layer).

If so, how should i choose the thermal relief type and value?

ie., whether to choose small or large thermal relief.
How the values of annular over drill, Isolation width, spoke width were been chosen.

It would be very help ful to me if i could know these informations.


Suresh.
