摘要:
A circuit board includes a substrate, a circuit pattern and a through electrode. The circuit pattern is disposed on one side of the substrate in a thickness direction thereof. The through electrode is filled in a through-hole formed in the substrate with one end connected to the circuit pattern. The circuit pattern and the through electrode each have an area containing a noble metal component (e.g., Au component) and are connected to each other therethrough.

There is provided a lubricant composition which includes: a first particle having a spherical shape having a diameter of 1 to 300 nm, having a Mohs hardness of 5 or more, at an amount of 0.01 to 40 weight %; and a second particle, having a diameter of 500 nm to 50 μm, having a Brinell hardness of 17 HB or less, at an amount of 0.01 to 40 weight %. The lubricant composition can form a bearing structure when the lubricant composition is subjected to an extreme pressure. The second particles are deformed into a retainer for the first particle.

An electronic device includes a substrate and an electronic component. The substrate has a metallized trace. The metallized trace has a metallized layer and an insulation layer. The metallized layer has a high melting point metal component and a low melting point metal component, the high melting point metal component and the low melting point metal component being diffusion bonded together. The insulation layer is formed simultaneously with the metallized layer to cover an outer surface of the metallized layer. The electronic component is electrically connected to the metallized layer.

摘要:
The present invention includes a step of cooling a molten metal within a fine space present in the inside of an object and hardening it while applying a forced external force exceeding atmospheric pressure to the molten metal. The fine space is opened on the outer surface of the object in terms of one end thereof. The forced external force is given by at least one member selected among a pressing pressure, an injection pressure and a rolling compaction and applied to the molten metal from the opening surface side on which the fine space is opened, in a state that the other end side of the fine space is closed.

The present invention provides a method for producing nanometer-size spherical particles. The method includes a first step for producing intermediate spherical particles. The intermediate spherical particles include a polycrystalline or single-crystalline region, having a particle size of 1 to 300 μm. The method of the present invention further includes a second step for producing final spherical particles. The second step uses a swirling plasma gas flow having the central axis thereof, the central axis running through an area between an anode and a cathode of a plasma generator. The intermediate spherical particles are discharged along the axis to subject the intermediate spherical particles to a plasma atmosphere of the area to form the final spherical particles.
