An approach compatible with high volume manufacturing for assembling a photonic chip with integrated optical fibers involving placing a die on an assembly station, providing one or more optical fibers, placing the one or more optical fibers into corresponding one or more grooves of the die, bonding the one or more optical fibers to the die and performing an optical test of the die using the one or more optical fibers, and severing the one or more optical fibers. The die can be removed from the assembly station while retaining a predetermined length of each severed optical fiber and the one or more optical fibers can be prepared for assembly to a next die.

Fiber attach assembly and test automation

A flip chip assembly is disclosed that includes a die with die circuitry and a plurality of electrical contacts electrically connected to the die circuitry. A substrate includes electrical contacts that are juxtaposed with and electrically connected to corresponding die electrical contacts. A passive component is disposed between the die and the substrate, and includes a dielectric disposed between a first electrode and a second electrode. The first electrode is electrically connected to a first of the die electrical contacts and a corresponding substrate electrical contact, and the second electrode is electrically connected to a second of the die electrical contacts and a corresponding substrate electrical contact.

Flip chip assembly with connected component

A clip connects two ferrules together, without a housing, to form a fiber optic connection. The clip has proximal and distal ends which define, and the clip has arms extending along the longitudinal axis to hold a cable-side ferrule in connection with fixed ferrule connected to a photonic module or die. The arms form an opening through which the cable-side ferrule is passed for connecting to the fixed ferrule. The arms have resilient bends forming a spring that can be resiliently extended along the longitudinal axis. The arms have a contact area at their ends which grasp the end of the cable-sided ferrule. The arms resiliently retract to compress the cable-sided ferrule towards the fixed ferrule with a predetermined force. The clip is positioned with respect to the circuit board using a pick and place system. The clip is not taller than either ferrule portion, enabling a limited vertical clearance.

Connecting mid-board optical modules

A micro-electronic cover has a planar portion sized and dimensioned to be positionable over and cover electronic components that are electrically connected on a board. The cover has a peripheral edge surrounding the planar portion and the electronic components. The peripheral edge connects the planar portion with the board to define a cover interior. The peripheral edge includes a side opening which provides access for passage of a connector part from a exterior to the cover to a position within the cover interior.

Connecting mid-board electronic devices

A component and chip assembly apparatus includes an assembly stage configured to support a chip, the chip including grooves defining a first pitch, the grooves including a first groove opening configured to receive a plurality of optical fibers and to align the plurality of optical fibers. A picker brings a fiber component including a plurality of optical fibers having a second pitch into contact with the chip such that each optical fiber is aligned with a respective groove. At least one of the assembly stage and the picker includes a comb having a plurality of teeth that define individual cavities therebetween, the cavities having a first cavity opening to receive the optical fibers and isolate each optical fiber from one another and pre-align the optical fibers so as to adjust the second pitch to substantially match the first pitch.
