Abstract: An interposer for an integrated system comprises a plurality of first connecting members and a plurality of second connecting members to be electrically connected to each other and a contact area realizing an electric short circuit of a group of the first connecting members which are electrically equivalent or homologous transporting a same signal, the contact area being electrically connected with at least one of the second connecting members thus realizing a scrambling between a number of the first connecting members and a number of the second connecting members.
