Claims
- 1. A suspension assembly comprisinga mount plate having a load beam mounted thereon, and a circuit element disposed on the load beam; wherein the load beam comprises a balanced liquid crystal polymer material disposed between, and in intimate contact with a first metal layer and a second metal layer.
- 2. A suspension assembly as in claim 1, wherein the first metal layer, the second metal layer, or both, is stainless steel.
- 3. A suspension assembly as in claim 1, wherein the first metal layer and the second metal layer have a thickness of about 30 micrometers to about 70 micrometers.
- 4. A suspension assembly as in claim 1, wherein the thickness of the first metal layer is different from the thickness of the second metal layer.
- 5. A suspension assembly as in claim 1, wherein the balanced liquid crystal polymer material has a tensile strength in a flow direction versus a direction perpendicular thereto of less than 5:1.
- 6. A suspension assembly as in claim 1, wherein the balanced liquid crystal polymer material has a tensile strength in a flow direction versus a direction perpendicular thereto of about 3:1 or less.
- 7. A suspension assembly as in claim 1, wherein the balanced liquid crystal polymer material has a coefficient of thermal expansion in a flow direction versus a direction perpendicular thereto of less than 1.5:1.
- 8. A suspension assembly as in claim 1, wherein the balanced liquid crystal polymer material has a coefficient of hygrothermal expansion of less than about 10 ppm/% RH.
- 9. A suspension assembly as in claim 1, wherein the balanced liquid crystal polymer material has a coefficient of hygrothermal expansion of less than about 5 ppm/% RH.
- 10. suspension assembly as in claim 1, wherein the balanced liquid crystal polymer material has a dielectric constant which is substantially unaffected by changes in humidity.
- 11. A suspension assembly as in claim 1, wherein the balanced liquid crystal polymer material has a thickness of about 10 to about 50 micrometers.
- 12. A suspension assembly comprising:a mount plate having a load beam mounted thereon, and a circuit element disposed on the load beam; wherein the load beam comprises a balanced liquid crystal polymer material disposed between, and in intimate contact with a first metal layer and a second metal layer, and further wherein the balanced liquid crystal polymer has a tensile strength in a flow direction versus a direction perpendicular thereto of less than 10:1.
- 13. A suspension assembly comprising:a mount plate having a load beam mounted thereon, and a circuit element disposed on the load beam; wherein the load beam comprises a balanced, multi-layered liquid crystal polymer material disposed between, and in intimate contact with a first metal layer and a second metal layer.
