Abstract
A method and apparatus are provided for aligning an optical array with a substrate. The method includes the steps of aligning the substrate with a set of alignment structures on an alignment fixture, transmitting a plurality of optical signals from the fixture through the substrate, and automatically aligning the optical array to the substrate using the transmitted plurality of optical signals and a pick and place machine.

A method of aligning an optical array with a substrate, such method comprising the steps of:
- aligning the substrate with a set of alignment structures on an alignment fixture;
- transmitting a plurality of optical signals from the fixture through the substrate;
- and
- automatically aligning the optical array to the substrate using the transmitted plurality of optical signals and a pick and place machine.
An apparatus for aligning an optical array with a substrate, such apparatus comprising:
- a substrate aligned with a set of alignment structures on an alignment fixture;
- a plurality of optical signals transmitted from the alignment fixture through the substrate;
- and
- a pick and place machine adapted to align the optical array to the substrate using the transmitted plurality of optical signals.
A method of aligning an optical array with a substrate, such method comprising the steps of:
- providing a substrate aligned to an alignment fixture;
- identifying a first plurality of registration marks in the alignment fixture with a first recognition module;
- identifying a second plurality of registration marks on the optical array with a second recognition module;
- and
- attaching the optical array to the substrate, such that the first plurality of registration marks of the optical array are located at a known distance from the second plurality of registration marks in the alignment fixture, with respect to a plane created by a first surface of the alignment fixture.
An apparatus for aligning an optical array with a substrate, such apparatus comprising:
- a substrate aligned to an alignment fixture;
- means for identifying a first plurality of registration marks in the alignment fixture;
- means for identifying a second plurality of registration marks on the optical array;
- and
- means for attaching the optical array to the substrate such that the first plurality of registration marks of the optical array are located at a known distance from the second plurality of registration marks in the alignment fixture, with respect to a plane created by a first surface of the alignment fixture.
