Electrical contacts with compliant supports

1. 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,

wherein the set of support elements is substantially flat.

2. The assembly of claim 1 , wherein the first set of electrical contacts include raised pads located on a set of traces on the flex circuit.

3. The assembly of claim 2 , wherein the raised pads comprise plated electrical contacts.

4. The assembly of claim 1 , wherein the compliant support backing comprises metal.

5. The assembly of claim 1 , wherein the compliant support backing forms at least part of a cover that substantially covers the second side of the flex circuit.

6. The assembly of claim 5 , wherein the cover comprises metal.

7. 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.

8. The assembly of claim 7 , wherein the bottom cover forms a recess sized to hold the flex circuit.

9. The assembly of claim 1 , further comprising at least one preamp that connects to the first set of electrical contacts.

10. The circuit of claim 9 , wherein the at least one preamp is located on the flex circuit adjacent to the first set of electrical contacts.

11. The assembly of claim 1 , wherein the electronic component is a head gimbal assembly.

12. 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.

13. The circuit of claim 12 , wherein the substrate is flexible.

14. The circuit of claim 13 , wherein the substrate comprises plastic.

15. The circuit of claim 12 , further comprising at least one preamp that connects to the set of plated electrical contacts via the set of traces.

16. The circuit of claim 15 , wherein the at least one preamp is located adjacent to the set of plated electrical contacts.

17. The circuit of claim 12 , wherein the set of plated electrical contacts is higher than the set of traces relative to the substrate.

18. The circuit of claim 12 , wherein the relief between each of the set of plated electrical contacts is configured to coincide with a set of support elements that individually support each of the set of plated electrical contacts.
