PROCESSO PARA PREPARAR UM TRAJETO ELETRICAMENTE CONDUTOR EM UMA CAMADA DIELETRICA IMPRENSADA ENTRE DUAS CAMADAS CONDUTIVAS E ATRAVES DE UMA CAMADA DIELETRICA IMPRENSADA ENTRE DUAS CAMADAS DE COBRE,E ARTIGO

摘要

A conductive through-hole hole is formed through a dielectric sandwiched between conductors by forming a noncircular hole in a conductor, etching a hole through the dielectric and by deforming at the conductor which has been undercut during the etching.
