Abstract
A mechanically stable main body having a cutout, into which an ESD protection element is at least partly embedded and mechanically fixed by means of a connection means. Electrical terminals of the protection element are connected to terminal pads on the top side of the main body by way of a structured metallic layer bearing on main body and protection element.
Claims9
A carrier plate for an electrical component
- comprising a mechanically stable main body, having external contacts on the underside and terminal pads for the component on the top side,
- comprising a cutout, into which an ESD protection element is at least partly embedded, wherein the electrical terminals of the protection element are accessible from the top side of the main body,
- wherein the protection element is mechanically fixedly embedded in the cutout of the main body by means of a connection means, the protection element being discrete from the main body and including an interspace between the protection element and the outer walls of the cutout,
- wherein the electrical terminals of the protection element are connected by way of a structured metallic layer to the terminal pads on the top side,
- wherein the main body is a crystalline, ceramic or vitreous main body,
- wherein an outwardly facing surface of the protection element terminates flush with a surface of the main body, and
- wherein the structured metallic layer bears on the two flush surfaces.
