Abstract: Apparatus for holding optical fibers in a matrix configuration comprises a holder member (20) and a pair of parallel alignment members (25) extending in an X direction and attached to the holder member. A plurality of fiber support members (11), each containing a column of optical fibers (13) are arranged side-by-side in the X direction, such that the end surfaces of the optical fibers form an X-Y matrix configuration. First and second alignment pins (16) bear against opposite sides of each fiber support member. Each alignment pin extends beyond the fiber support member and bears against a reference surface of one of the alignment members (25). Clamping means (27) connected to the holder member forces the alignment pins against the reference surfaces of the alignment members. By making the reference surfaces in the alignment member of the requisite precision, one insures relative alignment of the fiber support members (11 ) with respect to each other. The holder member (20), in turn, includes an adjustment mechanism (37) for adjusting the angular orientation of the X-Y matrix configuration of fiber ends.

Abstract: A substrate (10) is formed having first and second opposite flat surfaces. Photolithographic masking and etching is used to form on the first surface of the substrate at least one lens (25) having a central axis. Photolithographic masking and etching is also used to form on the second surface of the substrate an optical fiber guide (23). The fiber guide is then used to mount an optical fiber(27) on the second surface of the substrate such that the central axis of the optical fiber is substantially coincident with the central axis of the lens, thereby giving the desired alignment.

Abstract: Optical fibers (15) are supported within a bonded support member (16) having along opposite sides first and second grooves (14) which are parallel to the central axes of the fibers being supported. A first opening (22) is formed in a holder member (21) which includes a first projection (27). A cantilever spring member (23) is formed in the holder member having a second projection (27) opposite the first projection. The bonded fiber support member (16) is inserted into the opening such that the first projection engages the first groove (14) on one side, and the second projection engages the second groove (14) on the other side of the bonded support member. Thereafter, the bonded support member is locked into position and the holder biases one end of it against a polishing wheel (29) to permit polishing along a plane which is perpendicular to the axes of the optical fibers. By making the grooves in the support member by photolithographic masking and etching, and by making the projections in the holder by electron discharge machining, one can assure great alignment accuracy. The cantilever spring is preferably made by electron discharge machining to be part of a monolithic holder member and is made to exert a sufficient bias to hold the support member temporarily in place. Thereafter, the support member is locked in place by biasing a coil spring (28) against it. This use of spring bias means for holding the support member in the holder permits sufficient force to be exerted on the support members to permit polishing, but without risking cracking them.

Abstract: In one embodiment of the invention, photolithographic masking and etching is used to form a matrix array of mutually isolated ferromagnetic elements (25'). The elements are magnetized and a single layer of conductive ferromagnetic particles (33) is adhered to an upper surface of each of the ferromagnetic elements. The layer of particles is contacted with a layer of soft adhesive polymer (36) to cause penetration of the particles into the polymer. The adhesive polymer is then hardened to assure containment of the particles in the polymer. The hardened adhesive polymer is removed and located between the first and second conductor arrays (40-43) that is to be interconnected; for example, it is located between the bonding pads (43) of a chip (42) and the bonding pads (40) of a substrate (39) to which the chip is to be connected. The adhesive polymer is then softened by heating and compressed between the first and second conductor arrays to cause it to adhere to the conductor arrays and to interconnect them and is thereafter hardened to form a unified structure.

Abstract: A bundle (12) of optical fibers (13) is fixed in a matrix array by apertures in a guiding plate (14) and a securing plate (15). The apertures (18) in the guiding plate are larger than those in the securing plate and the securing plate apertures (17) are funnel-shaped to aid in insertion of the fibers. Each row of optical fibers may be inserted simultaneously by mounting the row on a uniquely designed vacuum holder (26).

Abstract: Automated insertion of pins (14) into apertures (12) in a backplane (10) is achieved by first shearing a predetermined number of pins from a continuous strip of pins (26). The sheared pins (12) are then engaged in a pin holder (134) which is indexed to locate the pins in registration with the apertures (12) in the backplane (10). The pin holder (134) is displaced towards the backplane (10) to insert the pins (14) into the apertures (12). As the pins are inserted, they are simultaneously engaged by a pair of guide fingers (244) which travel therewith to guide the engaged pins into the apertures without interfering with any previously inserted pins. The guide fingers disengage themselves from the pins once insertion thereof is substantially completed. An apparatus (10) is also described for carrying the above-described steps in sequence.
