Electrical contacts with compliant supports

An assembly comprising:

• a flex circuit including a first set of electrical contacts on a first side of the flex circuit, wherein the first set of electrical contacts is configured to connect to a second set of electrical contacts on an electronic component;
• and
• a compliant support backing adjacent a second side of the flex circuit and opposite the first set of electrical contacts, wherein the compliant support backing includes a set of support elements that individually support the first set of electrical contacts to increase the contact pressure between the first set of electrical contacts and the second set of electrical contacts when the flex circuit is connected to the electronic component,
• a top cover and a bottom cover, wherein the bottom cover substantially covers the first side of the flex circuit except for a portion adjacent to the first set of electrical contacts.

A circuit comprising:

• a substantially flat substrate;
• set of traces that terminate near an edge of the substrate;
• and
• a set of plated electrical contacts that connect to the set of traces, wherein the set of plated electrical contacts is located near the edge of the substrate,
• wherein the substrate includes a relief between each of the set of plated electrical contacts.
