ABSTRACT:
A method is provided for connecting two conductive layers in an electronic circuit package including the steps of placing one or more blind vias in a first substrate positioned on top of a first conductor; placing one or more blind vias in a second substrate positioned under a second conductor; attaching one or more signal lines to one or more of the one or more blind vias; and assembling ball grid array components such that the first conductor is electrically connected to the second conductor. Also claimed is an electronic circuit package incorporating the blind vias for electrical connection between layers in accordance with the present invention.
