- a micro machined optical conductor assembly 112 in the male connector portion 110 is cause to be brought into precise alignment with another micro machined optical conductor assembly 132 disposed in a right angle interface body 130.
- the female connector portion 120 guides the male connector portion 110 into precise registration with the right angle interface body 130.
- the housing parts of the optical connector are preferably formed of a high Tg material.
- Polyetherimide resins and in particular ULTEM® resin (a product of GE), have been found to be a suitable as housing material to embody the invention.
- the right angle interface body 130 is to be embedded inside a multi-layer circuit board.
- the female connector portion 120 mounts on a surface of the multi-layer circuit board, with a lower portion thereof extending down into the circuit board to engage the right angle interface body 130.
- the micro machined optical conductor assembly 132 is disposed above an integrated mirror 134 that provided a 90° transition for light traveling through the connector. This reflected light also travels through an additional micro machined conductor assembly 136 that provides coupling to a plurality of optical fibers 140, which are embedded inside the multilayer circuit board.
- An optional feature of the optical connector 100 is a spring-loaded door 122 inside the tapered passageway 124 of the female connector portion 120.
- the spring-loaded door 122 provides two functions. First, it prevents debris from falling down inside the connector and contaminating the optical interface surface 131 on the top of the right angle interface body 130. Secondly, the spring-loaded door 122 prevents light from being emitted through the tapered passageway 124 of the female connector portion 120 when no male connector portion 130 is inserted therein.
- the female connector portion 120 is securely held to the surface of the multilayer circuit board via locking connectors 124 that are inserted into holes formed through the multilayer circuit board.
- Off-board optical fibers 150 are connected into the male connector portion 110 so as to be in optical communication with the micro machined optical conductor assembly 112.
- precision of alignment of the optical connector is enhanced by alignment pins 114 extending from the male connector portion that interdigitate with precisely machined alignment holes (not shown in this view) formed in the top side of the right angle interface body 130.
- a perspective view of the right angle interface body 130 is illustrated.
- the precision alignment holes 138 are disposed on either end of the optical conductor assembly 132.
- Plural optical conductors 137 (preferably glass fibers) embedded in a silicon body 139 to form the optical conductor assembly 132.
- the optical conductor assembly is principally formed of silicon. MT type optical connector devices have been found to be suitable for embodying these assemblies.
- Anchor members 135 extend downward from the bottom side of the right angle interface body 130 to provide enhanced mechanical stability inside the multilayer circuit board.
- FIG. 4 another sectional view of the right angle interface body 130 of Fig. 2 is illustrated. Extending upwardly from the integrated mirror 134 through the micro machined optical conductor assembly 132 are plural glass fibers 137.
- FIG. 5 an initial pre-assembly schematic view is illustrated, showing the relative position of various lamination layers for composing the multi-layer printed circuit board.
- One layer is an electrical inner layer 502 according to known prior art practices.
- a registration plate 504 is provided to keep the board structure flat and having alignment holes to align and fix the optical connector during bonding.
- a prepreg layer 506 for bonding and embedding optical management structures is provided above the laminate layer 504.
- a laminate layer 508 is provided with the perimeter of the fiber management system 540 being routed out to compensate for thickness differences.
- An adhesive copper tape 512 is layered onto the top surface of the right angle interface body 530 to protect the glass fibers, alignment holes, and other surrounding structures from later processing steps.
- the copper tape 512 is adhered to the top surface of the right angle interface body 530 by an adhesive.
- the adhesive can withstand a temperature of at least 210°C and will not leave behind excessive residue when the copper tape 512 is later removed.
- an outer copper foil 510 is layered on as a top layer.
- the outer copper foil 510 is preferably about 18 micrometers in thickness.
- the circuit board layers may be formed with any suitable materials that are known in the art. Standard circuit board materials are available from a number of manufacturers including Isola of the U.K., Nelco Products, Inc. of Fullerton, California, and Polyclad Laminates of Franklin, New Hampshire.
- FIG. 6 a cross sectional view of the multilayer circuit board 600 is illustrated, post-lamination.
- the right angle interface body 530 is shown coupled to a fiber management system 540, with both being embedded inside a multi-layer printed circuit board 600.
- the right angle interface body 530 a basic alignment component of the entire optical connector, is aligned to the circuit board 600 via a registration plate 504.
- the registration plate 504 aligns and fixes the entire optical connector to the electrical pattern of the printed circuit board 600 by fixing the anchor members 539 into the registration plate 504.
- the registration plate 504 is aligned to the other layers of the multilayer printed circuit board 600 by using a traditional Lenkheit system.
- the right angle interface body 530 has angled sidewalls 531. These angled sidewalls 531 serve a dual purpose. One reason for having the angles sidewalls 531 is to facilitate cleaning around the interface body 530 with a laser that is used to ablate away the board layers above the interface body 530. The second useful purpose for the angled sidewalls is to provide for good alignment with the female connector portion.
- the multilayer printed circuit board 600 is shown after machining steps have been conducted on the board. Holes 602 have been drilled through the board 600 for connecting the female connector portion 920 to the surface of the board. A hole 604 has been machined into the upper surface of the board 600 and so is to expose the right angle interface body 530. The outer copper foil layer 510 has also been etched to provide conductive runs. At this time the copper tape 512 on the top of the right angle interface body 530 may be pealed off and the top surface of the right angle interface body cleaned 530. The protective copper tape 512 is left on the top surface of the right angle interface body 530 until the board 600 has been electrically tested and finally inspected.
- FIG. 8 the first step of assembling the female connector portion is illustrated.
- An anchor body 822 is securely engaged to the surface of the board 600 by inserting its anchors 824 into the holes 602 drilled in the board 600.

- FIG. 10 a detail view of the interface between the anchor body 822 and the female self-alignment body 924 is illustrated.
- the anchor body 822 engages the female self-alignment body 924 via a one way ratchet 926.

- a male self-alignment body 910 is inserted down into the female self-alignment body 920 (formed by the combination of the anchor body 822 and the female self-alignment body 924) to guide the male connected portion into precise registration with the top surface of the right angle alignment body 530.
- the alignment pins 914 of the male connector portion 910 are engaged with the precision machined holes 538 of the right angle alignment body 530.
- an electro-optical back plane 1200 according to an embodiment of the present invention is illustrated.
- the back plane 1200 has an optical carrier 1210 (preferably a fiber management system) embedded with a number of optical connectors 1220 according to embodiments of the present invention.
