In this paper, a de-embedding method is proposed for conducting accurate on-wafer device measurements in the gigahertz range. The method addresses issues of substrate coupling and contact effects and is therefore suitable for measurements with lossy technologies such as CMOS. The method assumes a probe-tip two-port calibration performed with well-known techniques and impedance substrates. By em...

The quality and economy of grinding depend on proper selection of grinding conditions for the materials to be ground. In order to evaluate the effect of heavy-duty grinding, a new performance index, which includes specific material removal rate, size accuracy, and grinding forces, was proposed. Robust design of experiment, including orthogonal arrays, the signal-to-noise ratio (SNR) method, and...

Abstract Fixture layout is a complex task that significantly impacts manufacturing costs and requires the expertise of well-trained engineers. While most research approaches to automating fixture process use optimization or rule-based frameworks, this paper presents novel approach using supervised learning. The proposed framework replicates 3-2-1 locating principle fixtures for sheet metal desi...

The currently available anti-buckling fixtures for uniaxial tension-compression testing of sheet metal could not fulfill the requirements and standards. In this study, a unique system to enable getting accurate repeatable isotropic kinematic behavior was designed. front surface specimen fully supported during initial position, tension, compression free from any buckling. Because using acrylic b...

Present situation in the industrial manufacture has brought new trends in the kind of flexibility and intelligence. That means new generation of intelligent manufacturing systems. New generation of clamping fixtures is represented by group of clamping fixtures which can be used in intelligent manufacturing systems. Important effect, which brings manufacturing times shortening, can be realized b...

The use of holding and inspection fixtures is common across many sectors manufacturing. concept a fixture for component, the purposes assembly or inspection, straightforward. design associated clamping strategy can have significant impact on process. This paper presents methodology investigating effects sequence production fixture, dimensional variability an automotive production-representative...

This paper discusses techniques for embedding and de-embedding the characteristics of two-port devices described by scattering parameters at microwave frequencies. Such techniques have wide applications in areas such as the measurement of the parameters of a semiconductor device mounted in a fixture, removal of the effects of cables, adapters, etc. and network analyzer calibration using variant...
