Abstract:
A method for electrically connecting multiple conductive surges in an electronic circuit package comprising the sequential steps of:applying to a first substrate a first surface metal forming a first conductive surface; applying lower dendrites to selected areas of the first surface metal; applying a dielectric material to cover the first surface metal and the lower dendrites; applying to a second substrate a second surface metal forming a second conductive surface; applying second-level dendrites to selected areas of the second surface metal; applying to the second substrate a third surface metal forming a third conductive surface; applying third-level dendrites to selected areas of the third surface metal; applying a dielectric material to cover the third surface metal and the third-level dendrites; applying to a third substrate a fourth surface metal forming a fourth conductive surface; applying upper dendrites to selected areas of the fourth surface metal; compressively attaching the first substrate to the second substrate such that the lower dendrites are mated to the second-level dendrites; and compressively attaching the second substrate to the third substrate such that the third-level dendrites are mated to the upper dendrites.
