    Abstract: A contact probe for a probe head for test equipment of electronic devices is provided. The contact probe includes a first end portion and a second end portion configured to realize a contact with suitable contact structures, and a body portion extended along a longitudinal development axis between respective the first and second end portions. The first end portion includes a base portion, a peripherally protruding element protruding from the base portion, and a hollow part having a base at a surface of the base portion and being surrounded by the peripherally protruding element. In addition, the peripherally protruding element is configured to penetrate into the contact structures.

    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.
