DISK WITH AN ELECTRICAL CONNECTION ELEMENT

摘要

The disk has a substrate (1) made from glass and exhibiting coefficient of thermal expansion. An electrically conductive structure (2) is arranged on an area of the substrate and exhibits layer thickness of 5 to 40 micrometer. An electrical connection element (3) exhibits another coefficient of thermal expansion, where the difference between the coefficients of thermal expansion of the substrate and the connection element is greater than or equal to 5x 10 ->6 degrees Celsius. A soldering compound layer (4) electrically connects the connection element to subregions of the conductive structure. The connection element is coated with nickel and silver. An independent claim is also included for a method for manufacturing a disk with an electrical connection element.
