Packages for devices and components
View Patent ↗A package for maintaining alignment of components includes a frame and a beam with the beam attached to the frame and one end of the beam. One or more components are mounted to the beam. The frame and a portion of the beam are separated from each other by a channel which allows portions of the beam to flex substantially independently of the frame when a force is applied to the frame. Thus, the effects resulting from forces applied to the frame are not experienced by the beam, or are at least attenuated, so that the alignment of the components mounted on the beam is substantially preserved.
1. A package suitable for housing optical and electrical components, the package comprising:
a frame;
top and bottom lids that cooperate with the frame to substantially define an enclosure;
a beam disposed within the enclosure and attached to the frame in a cantilever arrangement; and
at least one component disposed on the beam, wherein the package defines an open space interposed between the frame and a substantial portion of the beam and a damping material is placed in the open space thereby attaching the frame to the beam.
2. The package as recited in claim 1 , wherein the beam is configured such that neither the beam nor the at least one component disposed thereon come into contact with the top and bottom lids.
3. The package as recited in claim 1 , wherein the beam is configured and arranged so that the beam and the at least one component are collectively in a substantially non-resonant condition over a predetermined range of package excitation frequencies.
4. The package as recited in claim 1 , wherein the damping material is an adhesive.
5. The package as recited in claim 1 , wherein the frame and the beam are comprised of the same material.
6. The package as recited in claim 5 , wherein the material is one of metal; plastic; glass; or, ceramic.
7. The package as recited in claim 1 , wherein the at least one component is configured to connect to a device located outside of the package through optical ports passing through the frame to the beam.
8. A package suitable for housing optical and electrical components, the package comprising:
a frame;
top and bottom lids that cooperate with the frame to substantially define an enclosure;
a plurality of beams disposed within the enclosure and attached to the frame in a cantilever arrangement; and
at least one optical component disposed on each of the plurality of beams, wherein the package defines an open space interposed between the frame and the plurality of beams and a damping material is placed in the open space thereby attaching the frame to the plurality of beams.
9. The package as recited in claim 8 , wherein the plurality of beams are configured such that neither the plurality of beams nor the at least one component disposed thereon come into contact with the top and bottom lids.
10. The package as recited in claim 8 , further comprising:
a damping material, wherein the damping material attaches the plurality of beams to the frame.
11. The package as recited in claim 8 , wherein the damping material is an adhesive.
12. The package as recited in claim 8 , wherein the frame and the plurality of beams are comprised of the same material.
13. The package as recited in claim 12 , wherein the material is one of: metal; plastic; glass; or, ceramic.
14. The package as recited in claim 8 , wherein the at least one component is configured to connect to a device located outside of the package through optical ports passing through the frame to the beam.
