Abstract
An organic land grid array having multiple built up layers of metal sandwiching non-conductive layers, having a staggered pattern of degassing holes in the metal layers. The staggered pattern occurs in two substantially perpendicular directions. Traces between the metal layers have reduced impedance variation due to the degassing hole pattern.
