Abstract: A method for producing microporous objects with fiber, wire or foil core with periodic welding of nodes by movement of the substrate and the making of a porous mat. Microporous objects are created by deposition of small dimension of solid from liquid streams undergoing solidification with the simultaneous welding of the streams at various nodal locations concurrently during the deposition process. Bulk porous material objects are created containing open spaces within the microstructure. Inserts can be added to create internal geometries. Variations in pore density from near-zero to about 95% with gradient densities can be created. Screens can be used for forming column-like supports within the microporous object. Holes can be punched in the fiber core to create desired properties of denser regions and to limit the thermal expansion of the mat in a single direction.

Abstract: Ultra-small satellite droplets of molten metal, generated from capillary stream break-up, are selectively directed to predetermined locations on a substrate. The satellite droplets are produced at a high rate and are highly uniform because of the nature of capillary stream break-up. Applied harmonic disturbances are used to control and generate the satellite and parent droplets. The satellite droplets are electrostatically charged on a droplet-by-droplet basis and are then deflected by, e.g., an electric field to predetermined locations on a substrate. The substrate is moveable, attached to an x-y table, for facilitating the placement of satellite droplets on the substrate. The satellite droplets can be placed in individual locations on the substrate (e.g., for forming a ball grid array) or can be overlapped to form conductive traces. Because the satellite droplets have small diameters, these traces may have correspondingly small widths or pitches.

The surfaces in the print head that contact the liquid are coated to assist in priming the print head for a subsequent ejection event.

Abstract: A method and apparatus for retaining heat at a pin-in-hole rework site on a printed circuit board during solder fountain rework of the board. A preheated heat retention plate is attached to the rework side of the printed circuit board. The heat retention plate covers a substantial portion of the board surface.

By minimizing the escape of heat from the rework site, the number of solder cycles required to rework the board is decreased, resulting in reduced board rework times and increased board longevity.
