摘要： Described are a process for soldering at least one component having solder bumps to a substrate and a process for forming solder bumps on metal pads of an element, such as an IC package or substrate or both. The bumps are formed by stencil printing solder paste deposits on the metal pads, heating the solder paste deposits to reflow temperature of the solder in the solder paste deposits, and allowing the molten solder in each deposit to coalesce and during subsequent cooling solidify forming the bumps on the metal pads. The bumps are formed by conducting the stencil printing through apertures in an ultra-thick stencil, the apertures having trapezoidal crossection in the plane normal to the broad surfaces of the stencil with the top opening being smaller than the bottom opening and with the walls of the aperture sloping at an angle within a range of from 1 to 45 degrees from the vertical, the solder paste having a low tackiness and high metal loading, and the solder paste deposits covering an area which is equal to or exceeds an area of the metal pad in any ratio between 1.5:1 and 5:1. Bumps formed in this manner lead to the formation of reliable solder joints.

摘要： An anvil for a press for assembling a fastener to a plate having an aperture. The press includes a ram assembly for pressing the fastener into the plate aperture. The anvil includes a housing and a pin disposed in the housing. The pin is slidable between an extended position, partially extending outwardly of the housing and is adapted to extend through the plate aperture. The pin moves to a retracted position disposed within the housing for contact with the bottom surface of the plate. The anvil further includes a collar disposed in the housing and concentrically disposed around the pin. The collar includes a plurality of spaced apart collar sections, each collar section having a bottom flange retained by the housing and a top flange. The collar sections are movable between an expanded position when the pin is in the extended position, and a collapsed position when the pin is in the retracted position within the housing. The collar sections top flanges engage the pin top surface in the pin retracted position to form a barrier below the plate aperture to prevent fastener extruded material from protruding on the plate bottom surface after the fastener is inserted into the plate.

摘要： A telephone handset comprises elongated complementary upper and lower housing members that mate at their perimeters to form a hollow handset housing. The lower housing member includes a pair of spaced apart transducer receiving cavities, each being shaped to receive a cylindrical transducer surrounded by a flexible tubular gasket and form an acoustic seal therewith. Each gasket includes flanges around its circumference that project radially outward and in a direction opposite to the direction of insertion of the transducer/gasket assembly into its associated cavity. Such construction provides adequate mechanical retention between the transducer and the lower housing member and avoids the need for additional retaining hardware. The upper housing is joined to the lower housing using one or more pairs of side-mounted, interlocking hooks and latches. The upper housing further includes ribs, molded therein and positioned to maintain the transducers in place when it is joined with the lower housing.
