摘要:
A shaped member 1 having a predetermined configuration is formed by shaping powder of a valve metal under pressure (FIG. 1A), a sintered body 3 is formed by sintering the shaped member (FIG. 1B) and a pre-anodic oxidation film 9 is preliminarily formed on a surface of the sintered body 3 by electrochemical method (FIG. 1C) before a dielectric film 4 having a predetermined thickness is formed on the sintered body by anodic oxidation (FIG. 1D). The pre-anodic oxidation film 9 is formed by anodic oxidation or barrel chemical conversion to have a thickness larger than a thickness of an oxide film formed by natural oxidation (1 to 5 nm in a case of tantalum) and smaller than an oxide film 4.
摘要:
The present invention provides a chip capacitor, a fabrication method for the same, and a metal mold that can prevent the occurrence of the chip standing phenomenon even when carrying out soldering using reflow soldering, and that be applied to further down-sizing an decreasing of weight. Curved parts 26 and 36 that extend beyond the connecting tongue pieces 21 and 31 of side piece parts 22 and 23 rising in an upward diagonal direction with respect to the connecting tongue pieces 21 and 31 are formed by press bending processing, and thereby the side piece parts 22 and 32 are exposed in an upward rising direction relative to the connecting tongue pieces 21 and 31 at the external end surfaces 15b and 15c of the external resin packaging.
