Abstract:
A space transformer comprising:a first substrate provided with first electrical contact areas on one side thereof;first resilient contact structures, each having an elongate springable shape and a respective portion connected to a respective first electrical contact area of said first electrical contact areas, and extending from the respective first electrical contact area;a second substrate provided with second electrical contacts on one side thereof and third electrical contacts on an opposite side thereof, the second contact areas facing the first contact areas and each first resilient contact structure having a respective contact region connected to a respective one of the second electrical contacts, the second substrate being demountable from the first substrate; andsecond resilient contact structures, each having an elongate springable shape and a respective portion connected to a respective third electrical contact area of said third electrical contact areas and extending from the respective third electrical contact area,selected ones of the first resilient contact structures are interconnected with selected ones of the second contact structures, andselected ones of the first contact areas are spaced from one another by first distances, and selected ones of the second resilient contact structures have contact regions, remotely located from the portions thereof, which are spaced from one another by second distances which are different from the first distances.
