Abstract
Description
Die vorliegende Erfindung betrifft ein Verfahren zum elektrischen Kontaktieren eines elektronischen Bauelements, das eine Mehrzahl von auf Anlegen eines elektrischen Feldes reagierenden Werkstoffschichten sowie eine Mehrzahl von Elektrodenschichten aufweist und bei dem die einzelnen Werkstoffschichten jeweils zwischen zwei einander benachbarten Elektrodenschichten angeordnet sind. Ein solches Bauelement aus übereinander und alternierend zueinander gestapelten Schichten von Werkstoffschicht und Elektrodenschicht wird häufig allgemein als Stapel bezeichnet. Das heutzutage wohl bekannteste elektronische Bauelement dieser Art ist ein allgemein als Piezoaktor bezeichneter Stapel, der zunehmend mehr als Betätigungselement in Einspritzventilen der verschiedensten Motortypen für Kraftfahrzeuge zur Anwendung kommt. Die Werkstoffschichten sind bei diesem Piezoaktor Keramikschichten.The The present invention relates to a method for electrical contacting an electronic component that has a plurality of on an electric field reacting material layers and a plurality of electrode layers and in which the individual Material layers each between two adjacent electrode layers are arranged. Such a component of one over the other and alternating stacked layers of material layer and electrode layer to each other becomes common commonly referred to as a stack. The best known today Electronic component of this type is a generally known as a piezoelectric actuator designated stack, which is increasingly more than actuator in injectors the most different engine types for Motor vehicles is used. The material layers are ceramic layers in this piezoelectric actuator.
Üblicherweise
weist ein solcher Stapel, in Draufsicht betrachtet, einen rechteckigen
oder quadratischen Querschnitt auf. Er wird an zwei sich gegenüberliegenden
Umfangsseiten elektrisch kontaktiert. Um dies technologisch sorgfältig durchführen zu können, wurden
die Elektrodenschichten in der Vergangenheit geometrisch so ausgelegt,
dass sich nur jede zweite Elektrodenschicht seitlich bis zur einen der
beiden Umfangsseiten erstrecken, während sich die jeweils anderen
Elektrodenschichten nicht bis hin zu dieser einen Umfangsseite hin
erstrecken. Entsprechendes gilt für die andere Umfangsseite des Stapels
analog. Diese Situation ist in
