Abstract:
The invention relates to a contact-distance transformer (4) of an electrical testing device (1) for testing an electrical test item (7), in particular wafers (8), said contact-distance transformer (4) being suitable for reducing the distance between electrical contacts (16, 19) arranged next to one another, and having a non-electrically conductive carrier structure (28) occupying a first side (17) and a second side (18), wherein first electrical contacts (16) are arranged on the first side (17) at a contact distance (a) to one another, and second electrical contacts (19) are arranged on the second side (18) at a smaller contact distance (b) to one another in relation to the first contacts (16) of the first side (17), wherein the first contacts (16) are connected to the second contacts (19) via electrical connections (20) which are passing through the carrier structure (28) and/or which are arranged on the carrier structure (28). According to the invention, both the carrier structure (28) and the electrical connections (20) are formed as 3D-printed components (27). The invention also relates to an electrical testing device (1), and a method for producing a contact-distance transformer (4).
Abstract:
The invention relates to a configuration, comprising a first circuit board (ELP), which has a contact surface (KF) for contacting a connection element (VE), said contact surface (KF) comprising a central contact point and a concentric ring enclosing said central contact point; a second circuit board (ZLP); and a connection element (VE), which is electrically contacted on a first side with the second circuit board (ZLP) and which comprises a first spring element (FE1) and at least one second spring element (FE2, FE3) on a second side, which is opposite the first side, said first spring element (FE1) being electrically contacted with the central contact point of the first circuit board (ELP) and the at least one second spring element (FE2, FE3) being electrically contacted with the concentric ring of the first circuit board (ELP).
