Abstract: Method and apparatus for fluxlessly solder bonding a solder mound (2) to a solder wettable surface (8,10). A heated gas (12), preferably a reducing or non-reactive gas, is directed at a solid solder mound (2). Gas is heated to a temperature sufficient to melt solder mound. The heated gas is directed at the molten solder mound (2) at a momentum sufficient to disperse an oxide layer at the surface of the molten solder mound (2). Dispersing the oxide layer permits the molten solder to wet the solder wettable surface. The molten solder is cooled to form a solder bond.

Abstract: A direct optical connector (DOC) comprised of first (201) and second members, each including a plurality of light emitting (202, 204) and light detecting (205, 203) locations, operative in combination with energy transfer media (210) to form direct optical connections between the light emitting locations (202, 204) and the light detecting (203, 205) locations, wherein said first (201) and second members are adapted for reclosable connection to each other whereupon the light emitting locations (202) on one member are aligned with the light detecting locations (205) on the other member. The first (201) and second members of the preferred DOC are modular. Alternative forms of energy transfer media (210) are used in various embodiments of the invention including lenslet arrays, imaging fiber plates (IFPs), and energy transfer fiber plates (ETFPs). These media have differing alignment criteria, differing degrees of immunity from crosstalk, differing degrees of transfer efficiency, different manufacturing costs, etc., thereby permitting the fabrication and/or use of a connector most suited to meet the requirements of a particular application. A modular half of a DOC can be used in conjunction with a remote optical connector (ROC) to channel light over relatively long distances. The invention also encompasses processes for fabricating ROCs.
