    摘要： The invention provides an automatic system and method using x-ray inspection to image arrays of electrical interconnections on electronic devices. The electron beam of a rotating anode X-ray tube is deflected relative to the anode to cause emission of x-rays from different regions of the anode at different times. The x-ray tube is located at an inspection station for the electronic devices and disposed to irradiate a first part of the array of interconnections with x-rays emitted from a first region of the anode and to irradiate a further part of the array of interconnections with x-rays emitted from another region of the anode. X-rays emerging from the array of interconnections are detected and used to image part at least of the array in order to automatically register interconnection integrity failures and/or detect a performance trend in the formation of the connections. Typically, the arrays of electrical interconnections are established between a ball grid array on the underside of an electronics package and an array of blobs of solder paste on a printed circuit board.

    摘要： A system and method to predict a failure of an imaging system that includes a radiation source having an x-ray tube assembly is provided. The system includes a storage medium having a plurality of programmable storage instructions to instruct a processor to perform the steps of acquiring an age of the x-ray tube assembly, calculating a baseline probability of a survivability of the tube assembly for a remaining time period dependent on the age of the tube assembly, acquiring measurement of at least one operating parameter of the x-ray tube assembly, and automatically changing the baseline probability of a survivability of the imaging system for the remaining time period in response to the measurement of the at least one operating parameter of the x-ray tube assembly.

    摘要： A multiple energy x-ray source device is disclosed. Embodiments include a dual x-ray source comprised of two x-ray tubes mounted in separate housings. Each x-ray tube operates at a different power level, and each produces a characteristic x-ray signal. The x-ray sources are mounted on a common support structure, and are adjustable with respect to one another and with respect to the support structure so as to provide the ability to precisely align the focal spot of the x-ray signal emitted by each. Interconnection of the x-ray sources is provided by way of interlocking beam shields affixed to each source.

    摘要： A smoke detector comprises a soft x-ray source (10) and an air space (16) communicating with ambient air (18) and positioned so that soft x-rays produced by the soft x-ray source (10) pass into the air space (16) to ionise air in the air space (16). A detector (14) is positioned for detecting ionised air in the air space (16). Smoke particles entering into the air space (16) mop up ionised air. This leads to a reduction in the number of ions detected which triggers an alarm. The soft x-ray source (10) preferably comprises a substrate (22) on which are provided a plurality of nanometer scale elongate structures (28). The elongate structures (28) are provided in an evacuated chamber (42) formed between the substrate (22), a spacer (30), and a laminated film (36). The laminated film (36) comprises an aluminum foil layer (38) and a supporting nylon layer (40). A voltage converting circuit (44) is powered by a 9 volt DC battery and applies a 1.5 kV DC voltage between the substrate (22) and the aluminum foil layer (38). In use, the electrical voltage induces field emission of electrons from the elongate structures (28). The electrons are accelerated across the chamber (42) to the aluminum foil layer (38), where they collide with the foil layer (38) and produce the soft x-rays.
