Manufacturing System Using Solder Self-Alignment With Optical Component Deformation Fine Alignment

US Patent:
6543114, Apr 8, 2003
Filed:
Mar 8, 2001
Appl. No.:
09/802731
Inventors:
Walid A. Atia - Lexington MA
Steven D. Conover - Chelmsford MA
Eric E. Fitch - Medford MA
Sean P. OConnor - Wollaston MA
Randal A. Murdza - North Andover MA
Assignee:
Axsun Technologies, Inc. - Billerica MA
International Classification:
B23Q 1700
US Classification:
2940704, 2940705, 2940709, 29445, 29840, 22818022, 228155
Abstract:
A process for assembling micro-optical systems, such as optoelectronic and/or fiber optic components uses solder self-alignment to achieve a coarse, passive alignment of optical components relative to the optical bench. The fine, final alignment is performed using plastic deformation of the optical components to thereby improve the alignment of the optical components. As a result, the sub-micrometer alignment accuracies are attainable, if required.

Optical Bench Assembly Solder Fixture And Method

US Patent:
6467680, Oct 22, 2002
Filed:
Oct 10, 2000
Appl. No.:
09/685533
Inventors:
Sean P. OConnor - Wollaston MA
Eric E. Fitch - Medford MA
Assignee:
Axsun Technologies, Inc. - Billerica MA
International Classification:
B23K 3102
US Classification:
228245, 22818021
Abstract:
An assembly fixture for optical benches comprises a jig base, having at least one blind hole. The jig base is formed with a surface that is a non-wetting to solder material. The blind hole is shaped and sized in response to dimensions of the optical bench. The fixture further comprises a bench jig shroud. This shroud at least partially covers optical benches installed in the blind holes. Preferably, previsions are made in the top of the jig base at the interface with the jig shroud to facilitate its stable placement on the base.
