Wall thickness of a via hole...

C Shiva

 Hi all,

 What is the standard via hole wall thickness for micro, buried and PTH? When putting of vias for a power signal, it is an important issue to maintain the flow of sufficient current. Any feedback will be appreciated.

Regards,

Shiva.

    Hi Shiva,

     If your doing a class 2 board, then the hole wall thickness must be 0.8 mils absolute minimum. For class 3, it must be 1 mil absolute minimum.
