Abstract
An bench assembly alignment apparatus and method provides for precision alignment of the assembly with an alignment feature on a substrate. The bench assembly may comprise, for example, a fiber array to be mounted to, and aligned with, an opto-electronic device within a device package. Passive alignment of the bench position and orientation is achieved in a manner that affords improved device yield and increased precision in an economical process that eliminates the need to fabricate an additional alignment surface on the side wall of the bench.
Claims12
A bench registration system for registering a bench with an alignment feature comprising:
- a fiber bench including a registration groove comprising a V-groove;
- and
- a rod in the registration groove, a portion of the rod engaging the alignment feature, wherein the rod contacts the registration groove at an inner contact point and an outer contact point, and wherein an outermost registration surface of the rod portion is laterally positioned beyond an outer wall of the fiber bench.
A method for registering a known position on a bench with an alignment feature comprising:
- forming a fiber bench having a registration groove comprising a V-groove;
- mounting a rod in the registration groove such that the rod contacts the V-groove at an inner contact point and an outer contact point;
- installing the bench on a substrate having an alignment feature such that an outermost surface of the rod engages the alignment feature.
A fiber bench registration system, comprising:
- a substrate including an alignment feature;
- a fiber bench including a registration groove comprising a V-groove;
- and
- a reference element installed in the registration groove, the reference element engaging the alignment feature, wherein the reference element contacts the registration groove at an inner contact point and an outer contact point, and wherein an outermost registration surface of the reference element engages the alignment feature.
