  • Patent number: 9975206
    Abstract: Solder paste compositions and methods for applying solder paste. The solder paste includes lubricating additives to the flux to decrease friction and the changes of metal to metal contact between the surfaces of the solder balls and other surfaces that the solder balls come into contact with. The solder paste also includes solder balls of different average sizes, that improves the desirable liquid like properties of the granular paste while further reducing viscosity. As such, the solder paste is used in current screen printing solder paste application methods without the risk of clogging or agglomeration of solder paste particles on surfaces. The solder paste is also used in jetting or dispensing solder paste application methods without the risk of clogging or agglomeration within the cylinders/containers or apertures and nozzles that are used within such methods.

  • Publication number: 20150323319
    Abstract: The technology disclosed relates to methods and devices that compensate for displacements in a pattern or deformations of a workpiece. In particular, this relates to using timing to compensate for displacements along a first axis along the scanning direction while using resampling, interpolation or a similar method to compensate for displacements along a second axis that is substantially orthogonal to the first axis. The scanning direction may be an actual direction of movement of the scanning head or it may be a direction perpendicular to an orientation of an image projected onto a workpiece.

  • Patent number: 9164373
    Abstract: The problem of mura in large area photomasks is solved or at least reduced by setting up a writing system to write a pattern with high accuracy and with the optical axes essentially parallel to the movement axes of the stage, then writing photomasks in two passes with the substrate rotated to different angles on the stage. The angle between the orientation of the first and second pass is larger than about 10 degrees, larger than about 20 degrees or larger than about 35 degrees and it can be approximately 10 degrees, approximately 50 degrees, approximately 60 degrees or approximately 90 degrees. The substrate is physically rotated on the stage and aligned with high accuracy after the rotation and the data driving the first and second exposure passes are derived from the first input data specification but processed according to the known oblique angles, so that the second pass is accurately overlaid on the first pass.

  • Patent number: 9090095
    Abstract: The technology disclosed relates to patterning of flexible substrate. One implementation can be applied for production of flexible displays and other electronic devices on flexible substrates. The substrate may be plastic film typically 50-150 microns thick and the size of the pattern features may typically be in the range 1-10 microns across. Larger and smaller structures are possible. The patterning is done by means of optical exposure, either by exposure of a photosensitive resist or lacquer, or by other thermal or photochemical interaction between the light and the substrate. The substrate may typically be loaded as a roll and after exposure and other processing it may be rolled up on a second output roll, so called roll-to-roll (R-to-R) processing.

The feeder wagon comprises a feeder wagon body slidably mounted to the tape feeder body for movement between a first, pickup position and a second, delivery position. The feeder wagon further comprises a feeder head mounted to the feeder wagon body for movement (1) with the feeder wagon body as it moves along the first path, and (2) along a second path transverse to the first path between a first, tape-engaged position and a second, tape-released position. The feeder head comprises a tape-engaging element engageable with component tape.

  • Patent number: 8885145
    Abstract: The current invention relates to writing or reading a pattern on a surface, such as in microlithography or inspection of mircrolithographic patterns. In particular, Applicant discloses systems recording or reading images by scanning sparse 2D point arrays or grids across the surface, e.g., multiple optical, electron or particle beams modulated in parallel. The scanning and repeated reading or writing creates a dense pixel or spot grid on the workpiece. The grid may be created by various arrays: arrays of light sources, e.g., laser or LED arrays, by lenslet arrays where each lenslet has its own modulator, by aperture plates for particle beams, or arrays of near-field emitters or mechanical probes. For reading systems, the point grid may be created by a sparse point matrix illumination and/or a detector array where each detector element sees only one spot. The idea behind the use of large arrays is to improve throughput.

  • Publication number: 20140262012
    Abstract: In a method for jetting droplets of viscous medium on a workpiece, a jetting machine iteratively jets the droplets of viscous medium from a jetting nozzle onto a first surface of the workpiece to form a single continuous mass of material at an edge of the first surface of the workpiece. At least a portion of the single continuous mass of material extends past the edge of the first surface and adheres to a second surface of the workpiece.

  • Publication number: 20140268088
    Abstract: The technology disclosed relates to methods and systems that can be used to reduce visible artifacts know as mura. In particular, it relates to producing alignment marks by physically modifying appearance of a layer of exposure or radiation sensitive material on a workpiece, then using those alignment marks or transferred direct or inverted images of those marks to realign a writing coordinate system between exposure writing passes, following physical movement of the workpiece within the writing system. The physical modifications described include mechanically pressing a mark into the layer, using a laser to ash or ablate the layer, or applying an ink or other substance to the surface of the laser.

  • Publication number: 20140170566
    Abstract: The present invention relates to customizing individual workpieces, such as chip, flat panels or other electronic devices produced on substrates, by direct writing a custom pattern. Customization can be per device, per substrate, per batch or at some other small volume that makes it impractical to use a custom mask or mask set. In particular, it relates to customizing a latent image formed in a patterning sensitive layer over a substrate, merging standard and custom pattern data to form a custom pattern used to produce the customized latent image. A wide variety of substrates can benefit from the technology disclosed.

  • Publication number: 20140053399
    Abstract: The technology disclosed relates to accommodating embedded substrates during direct writing onto a printed circuit board and to other patterning problems that benefit from an extended depth of focus. In particular, it relates to multi-focus direct writing of a workpiece by the continuous or step-wise movement of the workpiece during the sequence of exposures having different focus planes. In one implementation, a multi-arm rotating direct writer is configured for interleaved writing focused on two or more focal planes that generally correspond to two or more surface heights of a radiation sensitive layer that overlays the uneven workpiece. Alternating arms can produce interleaved writing to the two or more focal planes.
