    Abstract: A probe head for testing the operation of a device under test is disclosed. The probe head has a plurality of contact probes including a body extending along a longitudinal axis adapted to contact respective contact pads and having a substantially square or rectangular-shaped cross section, and a guide lying in a plane and provided with guide holes having a substantially square or rectangular-shaped cross section for slidingly housing the contact probes. In the plane of the guide the cross section of the guide holes and the cross section of the contact probes are rotated relative to each other around the longitudinal axis and have respective different orientations with respect to a reference system in the plane, so that an edge of the body is mechanically interfering with a corresponding wall of the guide holes The probe head also has a conductive portion formed at the guide and/or formed at another guide of the probe head being adapted to contact and short-circuit a corresponding group of contact probes.

    Abstract: A method of manufacturing a multi-layer for a probe card comprises providing first contact pads on an exposed face of a first dielectric layer and second contact pads on an exposed face of a last dielectric layer. Each dielectric layer is laser ablated to realize pass-through structures and the pass-through structures are conductively filled to realize conductive structures. The dielectric layers are superimposed in a way that each conductive structure contacts a corresponding conductive structure of a contiguous dielectric layer in the multi-layer and forms conductive paths electrically connected the first and second contact pads. The second contact pads having a greater distance between its symmetry centers than the first contact pads, the multi-layer thus performing a spatial transformation between the first and second contact pads connected through the connective paths.

    Abstract: A contact probe having a first end portion and a second end portion, a probe body extended along a longitudinal development direction between the first end portion and the second end portion is disclosed. The probe body has a pair of arms separated by a slot and extending according to the longitudinal development direction and a conductive insert extended along the longitudinal development direction, in a bending plane of the contact probe. The conductive insert is made of a first material and the contact probe is made of a second material and the first material has a lower electrical resistivity than an electrical resistivity of the second material. The conductive insert is a power transmission element of the contact probe and the arms are structural support elements of the contact probe during a deformation of the probe body.
