Aspects of the invention include a method of tuning an interconnect that couples a first structure that is a first integrated circuit or a first laminate structure to a second structure that is a second integrated circuit or a second laminate structure. The method includes obtaining a compression requirement for a spring in a compliant layer of the interconnect. A longer path length of the spring leads to greater compression and mechanical support. Current and signal speed requirements for the interconnect are obtained. A shorter path length of the spring leads to greater current-carrying capacity and greater signal speed. Specifications for the spring are determined based on the compression requirement and the current and signal speed requirements. Determining the specifications includes determining a number of active coils of the spring to be less than two.
