TL;DR: In this article , the authors proposed a real use case of servitization, about a complete automatic test equipment (ATE) for the searching and classification of defects in real industrial production machines, which can be sent to the cloud in real-time for fast and accurate classification of multiple defects.
Abstract: The push for increase production efficiency and reduce discards is calling for a new generation of automatic test equipment (ATE) relying on cloud architecture. In details, traditional in-line automatic test equipment can be connected by means of IoT technology to the cloud, where virtually unlimited complexity algorithms can increase the measurement accuracy. This paper introduces a real use case of servitization, about a complete ATE for the searching and classification of defects in real industrial production machines. The measurements taken on the workpiece are sent to the cloud in real-time for fast and accurate classification of multiple defects. The paper proposes a suitable architecture and provides proof-of-concept experimental results obtained with a (sample) batch of products. The classification of multiple classes of defect is achieved with 95% overall accuracy (and precision and recall better that 92% in any single class), whereas traditional in-line ATE can only classify binary conditions (i.e., good/not good).

TL;DR: A survey of typical construction methods and style concepts that were used during the past seven decades provides an index of progress as discussed by the authors, particularly those that influenced the utility of the equipment and the role of the product engineer who takes the concepts and ideas of the scientists and devises suitable designs that are effective, reliable, and producible, and of the production engineer who handles the problems attending the manufacturing of these designs.
Abstract: A survey of the typical construction methods and style concepts that were used during the past seven decades provides an index of progress. From rather haphazard constructions that prevailed during the first quarter of this century, the industry soon reached a period when mass production of radio equipment was possible, whereupon the role of the product engineer, who takes the concepts and ideas of the scientists and devises suitable designs that are effective, reliable, and producible, and of the production engineer, who handles the problems attending the manufacturing of these designs, became important. In this review, the design techniques of several eras will be noted, particularly those that influenced the utility of the equipment. The many developments leading up to new processes, the ever-changing objectives, closer tolerances and increasing complexity taking place during the second quarter of the century, lead us into the space age with the emergence of the transistor, missiles, computers and automation. Printed-wiring and other assembly techniques are described, from the simple manual operations to the programmed automatic insertion of component parts. The roles of dip soldering and wirewrap, flexible cabling, and standardization are recounted. The progress of miniaturization is reviewed, from using conventional parts through various methods up to the micromodule and other arrangements with different form factors and integration methods. Finally, more sophisticated microminiaturization approaches?thin films, and fabrication of solid-state circuits by forming, "growing," and electron-microscope techniques. Automatic testing, dynamics, cooling, and audio-visual aids are touched upon.
