Abstract: Arrays having a support structure and a plurality of connecting elements are described. Each connecting element is associated with at least one holding arm integrally linking the connecting element to at least one of (a) the support structure and (b) one or more of the other connecting elements. The connecting element of these arrays include a metal substrate having joining surfaces on opposite sides, where each joining surface has hard particles fixed on the metal substrate by a binder layer. Processes for producing such arrays and using the connecting elements are also described.

Abstract: The present disclosure relates to an array of connecting elements, the array comprising (i) a support structure, and (ii) a plurality of connecting elements, wherein each connecting element comprises a metal substrate having a first joining surface on one side of the substrate and a second joining surface on an opposite side of the substrate, wherein each joining surface comprises hard particles fixed on the metal substrate by a binder layer; wherein each connecting element is associated with at least one holding arm integrally linking the connecting element to at least one of (a) the support structure and (b) one or more other connecting elements.
