Application of Microwave Drilling to Electronic Ceramics Machining

2006 7th International Conference on Electronic Packaging Technology, 2006

Ceramic materials are important in electronic industry. A number of ceramics are used in micro-electronic packaging and substrate manufacturing. However, hardness and brittleness of ceramics cause many difficulties in their machining. In this paper, a novel method is introduced for ceramic machining which uses the microwave energy. The method is based on the phenomenon of local hot spot produced by ...


Switched mode power supplies EMC analysis: near field modeling and experimental validation

Proceedings of International Symposium on Electromagnetic Compatibility, 1995

An EMC analysis of a switched mode power supplies (SMPS) is presented which shows the variation of the radiation patterns, near field spatial distributions and radiation properties as the SMPS's load is altered. Depending upon the loading, the SMPS exhibits magnetic or electric dipole behavior. Currents and fields calculated by an accurate prediction model are compared with those measured.


Dielectric director for near-field microwave imaging

2009 3rd European Conference on Antennas and Propagation, 2009

A dielectric director has been introduced to enhance near-field radiation properties of ultra-wideband antennas. This paper presents a parametric study of selected parameters that define the director used to improve the radiation behavior of a balanced antipodal Vivaldi antenna. The near-field radiation distortion and intensity are of interest. The director permittivity is found to be the key parameter that controls ...

  • Application of Microwave Drilling to Electronic Ceramics Machining

    Ceramic materials are important in electronic industry. A number of ceramics are used in micro-electronic packaging and substrate manufacturing. However, hardness and brittleness of ceramics cause many difficulties in their machining. In this paper, a novel method is introduced for ceramic machining which uses the microwave energy. The method is based on the phenomenon of local hot spot produced by near-field microwave radiation. It is cheaper and more effective to the process of ceramics, and has advantages in improving process quality. The paper offers a model of microwave-drilling on a slice of ceramics and investigates the effect area of microwave. Parametric study is conducted and documented based on the proposed drilling model. In addition, a comparison is presented between the proposed microwave method and other methods, with the focus on the holes drilling of ceramics. Finally the paper discusses the prospect and issues of microwave-drilling in actual applications to micro-electronics industry

The proposed antenna is constructed on glass-epoxy FR-4 substrate with relative permittivity 4.6. Numerical results of the different design antenna parameters radiation characteristics, including current density on the patch, near field, gain and radiation pattern are presented.

  • Antenna-on-package concept: shielding of backside radiation and study of electromagnetic near field inside package

    In recent years a lot of research has been performed in the field of antenna integration. Very interesting is the integration of a planar radiating element in the package surrounding a chip. The electromagnetic field at the back of the antenna is not negligible, and may cause interference with the circuits in the chip, possibly encumbering the operation of the system. This interference was quantified by a numerical near field analysis, and shielding methods to reduce it were investigated

  • An analysis of a dipole antenna near a prolate head model using a hybrid NFM/MoM approach

    A hybrid approach using null field (NFM) method and method of moments (MoM) is proposed to solve the radiation problem of a dipole antenna near a prolate head model. In the proposed approach, the electromagnetic fields in the prolate, which is used to emulate a human head, is modeled by NFM and the dipole antenna is analyzed by MoM. The mutual coupling between the dipole antenna and the head model is fully taken into account by an iterative process. The proposed hybrid method combines the analytical attribute of NFM and the flexibility of MoM and can be extended to analyzing a system of multiple regions with different algorithms. Numerical results concerning the field inside the head model, and the input impedance of the antenna are presented. The accuracy and efficiency of the proposed algorithm are verified by comparing numerical results with other available data.
