摘要:
A method for manufacturing a gas separating unit which comprises laminating a metal plate on a material capable separating a hydrogen gas (palladium alloy fo il) by cladding, etching selectively a central portion of a cut clad plate (K) using an etching solution, to thereby expose an underlying palladium alloy foil layer, and providing a metal supporting plate on the other side of the palladium alloy f oil layer. The method allows the manufacture of a gas separating unit having an enhanced effective area of a material capable of separating a hydrogen gas and is excellent in the handlability of a material capable of separating a hydrogen gas during manufacturing.
摘要:
An electronic circuit device capable of providing a stable electrical connection between an electronic component chip and a connecting multi-layer substrate, and being downsized at high density; and a production method therefor. An electronic component chip (1) and a connecting multi-layer substrate (2) or electronic component chips are heated in an inactive atmosphere such as argon or a reducing atmosphere such as hydrogen and pressure-welded to each other with or without an intermediary of an interposer (6), or their joint surfaces are activated and then pressure-welded at room temperature or by heating, thereby producing an electronic circuit device (40) by directly and metallurgically joining them by using any one of the above methods.
