    摘要： An apparatus for depositing a selected pattern of solder onto a substrate comprising a substrate support, a solder ejector, and an orifice defining structure. The substrate support has structure for bearing a substrate on which one or more electronic components are to be mounted. The solder ejector has a housing that defines a cavity for containing molten solder. The orifice defining structure includes a flat disk having an orifice defined therethrough for producing a stream of molten solder and a disk support structure that supports the disk around the orifice and is replaceably coupled to the cavity-defining structure. Also disclosed is an apparatus that deposits a selected pattern of solder onto a substrate and includes a substrate support, a solder ejector that directs solder droplets to desired positions on the support, and an ejector aligner that adjusts the orientation of the solder ejector in two angular dimensions to enable adjustment of the trajectory of the stream of molten solder droplets.

    摘要： An apparatus for dispensing a fluid includes a dispensing chamber coupled to a dispensing orifice and a fluid reservoir. The dispensing chamber is coupled to a transducer which is adapted to change the volume of the dispensing chamber in response to a signal applied to the transducer. The signal is characterized by 1) an initial rise time RT1 during which an increasing amplitude signal is applied to the transducer to gradually expand the dispensing chamber from a first volume at a first amplitude to a second volume at a second amplitude; 2) a fall time FT during which a decreasing amplitude signal is applied to the transducer to contract or compress the dispensing chamber rapidly (relative to the initial rise time RT1) to a third volume at third amplitude; 3) a final rise time RT2 during which an increasing amplitude signal is applied to the transducer to gradually expand the dispensing chamber to a fourth volume at a fourth amplitude. Preferably, the first volume is less than the second volume, the second volume is substantially greater than the third volume, the third volume is less than the fourth volume, and the first volume is same as the fourth volume and both are equal to the nominal volume of the dispensing chamber. In addition, the fall time is substantially smaller than both the initial rise time and the final rise time. In the preferred embodiment, the waveform amplitude is negatively offset by its center (or nominal) to peak amplitude.

    摘要： A printer includes a dispensing head for dispensing viscous material, such as solder paste. The dispensing head defines a chamber and includes at least one source port and a dispensing slot, wherein the viscous material flows from a supply mounted to the source port, into the chamber and out the dispensing slot. Within the chamber, a stirring mechanism is mounted. The stirring mechanism is coupled to a drive mechanism that displaces the stirring mechanism through the chamber, thereby stirring the viscous material. The stirring mechanism is particularly effective in preventing or reducing compaction of solder paste within the chamber.
