    Recent developments in printed wiring boards (PWBs) for use in surface mounting technology (SMT) in Japan are reviewed. Particular emphasis is placed on the high-density multilayer PWBs, which are important for SMT. Requirement for PWBs with respect to wiring density and housing capability, electrical properties, characteristics required at time of mounting, and reliability are discussed. Design, ...

    For pt.IV see ibid., vol.7, no.1, p.20 (1991). Some of the problems related to corona and partial discharge damage to polymer insulators are outlined. The basic construction of polymer insulators for overhead lines, which consist of a core, weathersheds, and metal end fittings, is described. Two types in common use are suspension/dead-end type, which is used where line loads subject the insulator ... View full abstract»

    The basic performance requirements for heat-shrinkable components and the compounding and processing techniques that are used to meet these requirements are covered. The emphasis is on the electrical, mechanical, and environmental protection features of components for low-voltage (up to 1 kV) applications. The aim is to provide a fundamental understanding of the capabilities and applications of he... View full abstract»

    Attention is drawn to a parameter that plays a crucial role in determining the breakdown strength of transformer oil, yet which tends to be ignored. This parameter is the settling time, which can mean either the time interval between two consecutive measurements or the time for which an oil sample is stored before measurements begin. The term is used here in the former sense. Research carried out ... View full abstract»
