to a maximum limit of about 100 by volume as discussed above in addition a small amount of an organic binder material and vehicle is included for the formation of the greensheet layers and electrode layers which materials are completely burned off during the firing step according to the embodiment of fig3 a laminate 15 is produced in which the electrode terminations are provided at a surface of the laminate rather than at the edges thereof dielectric layers 16 and alternate electrode layers 17 are laminated to form a multi layer assembly vias 18 are bored through an outer dielectric layer down to the desired electrode layer 17 and are filled with conductive past 19 to provide surface terminations such as pins 20 and an i o pad 21 at a surface of an outer dielectric layer 16 it will be apparent that the electrode layers 17 of fig3 need not extend to the edges of the laminate 15 since edge electrodes are not employed thereon various ceramic materials are useful with the process according to the invention among these ceramic materials to name a few are alumina mullite glass ceramics and aluminum nitride however a preferred material is alumina al 2 o 3 also preferred for use in the invention are the glass ceramic materials which are disclosed in kumar et al u.
