Abstract: Method and system are disclosed for interactively developing at least one grid pattern, such as a microarray pattern, as well as an array set of such patterns, and a computer-readable storage medium having a program for executing the method given only a few user inputs through the use of a pointing device such as a mouse or trackball on a personal computer or workstation. Each array in the set typically has an identical number of rows and columns of points.

Abstract: A microarray scanning system for conducting microarray experiments on a planar substrate includes an excitation radiation source, a detection system, and a computational device, the planar substrate supporting a plurality of dilution marks containing a fluorophore and located on the substrate surface at predetermined distances from a fiduciual reference mark and/or a microarray.

Abstract: Method and system for overlaying at least three microarray images to obtain a multicolor composite image, which is then displayed on a monitor of a computer system. The microarray images are taken from a microarray scanner of a DNA microarray and can be viewed simultaneously through the use of the image overlays where each image is represented by a different color. Each pixel of the composite image is generated by the OR operator applied to all corresponding pixels of the microarray images. Registration of the microarray images can be altered with a keyboard or mouse of the computer system.

Abstract: A microarray scanning system for conducting experiments on a planar substrate includes an apparatus for translating the secured substrate in two axes, the substrate having at least one fiducial mark on the planar substrate as a means for positioning and aligning the substrate for subsequent spot placement, analysis, or comparison procedures. The at least one fiducial mark is deposited at a predetermined position relative to the at least one location of a corresponding microarray of test spots or samples.

Abstract: A method and system are provided for flipping a tray of parts such as integrated circuit packages including a pair of flippable storage trays. A first storage tray has an upper surface which forms a grid of storage compartments wherein each of the storage compartments is adapted to hold a single integrated circuit package. Initially, the first tray is received at a flip station from a first part processing station. Then, the first and second trays are joined together so that they mate. Then, the mated first and second trays are inverted so that the packages are held in the second tray. Then, the first and second trays are separated and the second tray which now holds the plurality of packages is transferred to a second part processing station. Then, the cycle is repeated with a third tray of parts and the now empty first tray.

Abstract: A method and system for three-dimensional imaging of objects, including integrated circuit interconnections and many other microelectronic assemblies and miniature parts, is used to greatly improve the efficiency of triangulation-based laser line scanning systems. A scanning beam is incident at a normal angle to the X,Y inspection plane with the scan line oriented at 45.degree., diagonal to an axis defining a first direction of motion. Motion of the imaging head along the axis is used to acquire line scan images in the non-orthogonal coordinate system having symmetry about the orthogonal axes of motion.
