Claims
- 1. The process of bonding a first workpiece to a second workpiece, comprising the steps of:fabricating a porous bonding pad from a matrix of randomly oriented metallic fibers; sintering the porous bonding pad for affixing each of the metallic fibers to adjacent metallic fibers; interposing the bonding pad between the first and the second workpiece; biasing the first and second workpieces into engagement with the bonding pad; and applying heat to the first workpiece to the second workpiece for transforming substantially all of the metallic fibers into a liquid for bonding the first workpiece to the second workpiece.
- 2. The process of bonding a first workpiece to a second workpiece as set forth in claim 1, wherein the step of fabricating the bonding pad comprises drawing metallic fibers in a wire drawing process to provide a uniform diameter thereof; andforming a matrix of randomly oriented metallic fibers to provide the porous bonding pad.
- 3. The process of bonding a first workpiece to a second workpiece as set forth in claim 1, wherein the step of applying heat includes directing heat between the first and second workpiece.
- 4. The process of bonding a first workpiece to a second workpiece as set forth in claim 1, wherein the step of applying heat includes concentrating heat between the first and second workpiece.
- 5. The process of bonding a first workpiece to a second workpiece as set forth in claim 1, wherein the step of applying heat includes directing infrared radiation between the first and second workpiece.
- 6. The process of bonding a first workpiece to a second workpiece as set forth in claim 1, wherein the step of applying heat includes applying heat in a hydrogen atmosphere for melting at least the surface of each of the metallic bonding fibers.
- 7. The process of bonding a first workpiece to a second workpiece, comprising the steps of:fabricating a porous bonding pad from a matrix of randomly oriented metallic fibers; sintering the porous bonding pad for affixing each of the metallic fibers to adjacent metallic fibers; interposing the bonding pad between the first and the second workpiece; biasing the first and second workpieces into engagement with the bonding pad; and applying heat to the first workpiece to the second workpiece for transforming substantially all of the metallic fibers into a liquid for bonding the first workpiece to the second workpiece upon solidification of the liquefied metallic fibers.
- 8. The process of bonding a first workpiece to a second workpiece as set forth in claim 7, wherein the step of fabricating the porous bonding pad includes drawing a metallic wire to provide a metallic fiber having a cylindrical diameter less than 50 micrometers; andfabricating the porous bonding pad from a matrix of randomly oriented metallic fibers.
- 9. The process of bonding a first workpiece to a second workpiece as set forth in claim 7, wherein the step of fabricating the porous bonding pad includes drawing a metallic wire to provide a metallic fiber having a cylindrical diameter less than 50 micrometers; andfabricating the porous bonding pad from a matrix of randomly oriented metallic fibers to provide a resilient bonding pad.
- 10. The process of bonding a first workpiece to a second workpiece as set forth in claim 7, wherein the step of applying heat includes directing heat between the first and second workpiece.
- 11. The process of bonding a first workpiece to a second workpiece as set forth in claim 7, wherein the step of applying heat includes concentrating heat between the first and second workpiece.
- 12. The process of bonding a first workpiece to a second workpiece as set forth in claim 7, wherein the step of applying heat includes directing infrared radiation between the first and second workpiece.
- 13. The process of bonding a first workpiece to a second workpiece as set forth in claim 7, wherein the step of applying heat includes applying heat in a hydrogen atmosphere for melting at least the surface of each of the metallic bonding fibers.
