    Abstract: The present invention relates to a two-level mounting board in which a second substrate is supported horizontally by a metal pin above a first substrate having a mounting electrode on an outer base surface, the free, lower end of the metal pin is inserted in a hole provided in the surface of the first substrate, and the metal pin is affixed by solder to an annular electrode land provided on the surface of the first substrate to form an outer periphery of the hole, wherein part of the ring of the annular electrode land is cut away to open the same. This provides a two-level mounting board in which metal pins can be connected reliably to the first substrate to support the second substrate horizontally, and a crystal oscillator using the same.

    Abstract: A printed circuit board for avoiding producing burrs, the printed circuit board includes a packaging substrate, at least one plated through hole, at least one first conductive portion, at least one non-conductive portion, at least one second conductive portion and at least one cut section. The plated through hole is formed on the packaging substrate. The first conductive portion and the second conductive portion respectively are adjacent to two sides of a peripheral of the plated through hole and separated by the non-conductive portion. Furthermore, the cut section is arranged on the non-conductive portion, thus the packaging substrate is cut without passing through the first conductive portion, and it will not cause the burrs on the first conductive portion.

    Abstract: A pair of soldering irons are fixed to a sliding plate at a predetermined interval. The soldering irons are integrally moved so as to reciprocate in a rectangular direction relative to a conveyor belt. One of the soldering irons is conveyed to a working position of the conveyor belt and the other of them is separated from the conveyor belt. While one of the soldering irons solders a circuit board, the other is cleaned. The circuit board has a slit into which a metal plate is inserted and soldered. For the slit, a soldering land constituted of a main-land and a sub-land is provided. The main-land is formed along one of longer sides of the slit. The sub-land is elongated from the main-land along a shorter side of the slit. The soldering land is not formed all around the slit so that the slit is not closed by solder when the circuit board is dip-soldered.

    Abstract: A photoresist is deposited on a seed layer on a substrate. A first region of the photoresist is removed to expose a first portion of the seed layer to form a via-pad structure. A first conductive layer is deposited onto the first portion of the seed layer. A second region of the photoresist adjacent to the first region is removed to expose a second portion of the seed layer to form a line. A second conductive layer is deposited onto the first conductive layer and the second portion of the seed layer.
