Abstract:
A method of producing a laminated multilayer printed wiring board formed from a plurality of individual layers each comprised of a dielectric organic material so as to form z-axis electrical interconnections; said method comprising:drilling through-holes in a predetermined array in a first said dielectric layer; filling said through-holes with an electrically conductive paste; drilling through-holes in a second array in at least a second said dielectric layer; filling said through-holes in said second dielectric layer with an electrically conductive paste; and laminating said first and second dielectric layers in superimposed surface contact whereby at least selective of the through-holes in said first dielectric layer are in alignment with selective of the through-holes in said second dielectric layer so as to cause the electrically conductive paste in said aligned holes to come into electrically conductive communication with each other.
