    摘要: Disclosed is a low thermal resistance surface mount component and a mounting substrate bump-connected therewith, capable of removing a soldered low thermal resistance surface mount component from a circuit board without harming the performance of the circuit board or the performance of the low thermal resistance surface mount component. The solder bumps 3 in an area approaching the periphery 2 of the low thermal resistance surface mount component 1 are composed of a solder of a melting point lower than that of the solder bumps 3 in an area approaching the center. The low thermal resistance surface mount component 1 on the circuit board can be removed by partial heating and by melting the solder bumps. However, when the component is partially heated in this manner, the heating temperature declines approaching the periphery compared to that of the center of the low thermal resistance surface mount component 1. Therefore, the solder bump composed of the solder of the low melting point is used in the area approaching the periphery so that the solder bump can be melted even at such a lower heating temperature. As such, the solder bump of the entire surface of the low thermal resistance surface mount component 1 is melted.

    摘要: In order to provide a two-dimensionally arrayed probe (element packaging structure) in which a multilayer element can be used as a piezoelectric ceramic transducer element, each defective element can be replaced and the ill connection of each element can be repaired, and in order to provide a multilayer electric part suitable for realizing such an element packaging structure, the multilayer electronic part is configured with a multilayer chip-like element having a surface electrode, an internal electrode and a back electrode on the one hand and a flexible board attached to one side surface of the chip-like element on the other hand, alternate ones of the electrodes along the multilayer of the chip-like element are connected electrically to each other by the electrode pattern of the flexible board thereby to form two electrode groups, and the end portions of the electrode pattern of the flexible board are used as the two electrode portions for external connection which are electrically connected to the two electrode groups.
