Introduction to Loss

Sonnet models three types of loss:

1.  Planar metal loss of polygons (circuit metal), top cover and ground plane.
2.  Via metal loss of via polygons.
3.  Dielectric loss of dielectric layers and dielectric bricks.

 There is a detailed discussion of metal and dielectric loss in Metalization and Dielectric Layer Loss in the Sonnet User's Guide.There is also a paper by Dr. James Rautio, president and founder of Sonnet Software, available on our web site which contains a detailed discussion of metal loss.
