A high resolution magnifying X-ray fluoroscope using a low dose beam includes a scintillator for receiving an X-ray beam and converting the X-ray energy into visible light. The scintillator is in intimate optical contact with a non-demagnifying image intensifier that presents the visible light image through a close-up lens system to an optically magnifying, autofocus, programmable, closed circuit video camera. The fluoroscope is mounted on a moveable frame in a position that is opposed to an X-ray source.

The rotating X-ray apparatus disclosed has a pair of driven rotatable rings with an X-ray source mounted for impinging a beam that passes through a specimen to an X-ray receptor. A reversible motor, controlled by a reversing switch, drives the rotatable rings around the specimen. The rotatable rings are mounted between a pair of frame plates that are supported on transverse rails for lateral movement.

A method for the amplification or intensification of dye images formed in a negative-working diazo system which comprises the steps of: (1) initially image-wise exposing a negative-working diazo layer to actinic radiation sufficient to convert a portion of the diazo compound contained therein to an active coupling constituent in the light-struck areas to form a first latent image, (2) developing the exposed diazo layer to effect coupling so as to form colored incipient images in the light-struck areas, (3) exposing the entire diazo layer from the same side as the initial image-wise exposure to actinic radiation of a greater amount than that used in the initial exposure, said amount of actinic radiation being sufficient to substantially photolyze the non-image areas while simultaneously creating second latent images beneath the already-developed areas, and (4) developing the exposed diazo layer again to effect coupling in said second latent image areas to form color therein and to amplify the initial colored incipient images. Further amplification may be obtained by exposing the diazo layer from the side opposite that of the initial exposure and again developing to effect coupling of any remaining diazo under the original dye image areas.

An X-ray inspection system for inspecting electronic components such as printed circuit boards includes a shielded cabinet having an exposure chamber divided into upper and lower portions by a support shelf for the object to be inspected. An overhead X-ray source directs an X-ray beam into the upper portion of the exposure chamber toward the object. An image intensifier including a thin radioluminescent plate and a microchannel plate multiplier is disposed in the lower portion of the exposure chamber and is optically coupled to a video camera therein.

A high resolution X-ray inspection system particularly adapted for electronic circuit components comprised of an X-ray cabinet including an X-ray tube which is located in a vertical tower and where the object and film are placed on a slidable support member located inside the lower portion of the cabinet, with the support member being slidable outwardly therefrom. The slidable support member includes provision for attaching, upon demand, a fluoroscopic imaging device whose output is optically coupled to a closed circuit TV camera located in the bottom of the housing beneath the slidable shelf. The fluoroscopic generator includes a thinly coated radioluminescent phosphor plate optically coupled to the input of an image intensifier comprised of a microchannel plate multiplier.

This invention relates to a system for the removal and reattachment of a ball grid array (BGA) package component to a printed circuit board, that is adapted for the real time X-ray inspection of BGA package removal and reattachment. The system comprises heating means comprising upper and lower heating platens juxtaposed to each other for the reception, support and application of heat to the workpiece comprising the BGA package and the printed circuit board, wherein the heating means is prepared from materials that are transmissive to X-ray radiation. Suitable x-ray transmissive materials are selected from high melting point polymers, aluminum, glasses and ceramics, and include materials having an atomic number less than 14. The system includes X-ray inspection means comprising means for generating an X-ray beam for producing an X-ray image of the workpiece, fluoroscopic imaging means for generating a visible X-ray image of the workpiece; and video camera means for viewing the X-ray image and generating a video output of the X-ray image. The system extends to the simultaneous detection and inspection of the workpiece by conventional video means within the visible spectrum.

A diazotype material useful for making duplicates of continuous tone originals, such as X-ray films, comprising a transparent film support having a coating of a layer thereon consisting essentially of at least two light-sensitive diazo compounds having different photolysis rates, couplers for the diazo compounds, an ultraviolet radiation absorbing material and homogeneously distributed in the layer at least about 7% by weight, based on the weight of lacquer, of an inert particulate material such as silica. The use of this material makes it possible to approximate a logarithmic photolysis, thereby providing sufficient linearity in the corresponding characteristic curve to achieve the desired duplicating results.
