Abstract:
A circuit board with a holding mechanism integrated into the circuit board for the holding of wired, electronic components. To this end, a connection bore is provided for receiving a connection wire or pin of the component. The connection bore is formed from two neighboring and partially mutually overlapping bores. In such case, the first bore is so placed relative to a second bore that ridges are formed in the interior of the connection bore as a result of the overlapping of the first and second bores. The ridges provide a narrowing of the open passageway through the connection bore. In this narrowing, the connection wire or pin is controllably, securely seized by the ridges.

A mounting structure for mounting a terminal at a circuit board, which allows the terminal to be mounted at the circuit board easily by using an automatic mounter and facilitates inspection of the bonding state at the mounting area where the terminal is mounted at another board, is provided. The mounting structure for a circuit board terminal also assures a sufficient level of strength at the terminal mounting area, reduces the electrical resistance and improves the usable area ratio at the circuit board.

One or a plurality of hollow through electrodes (1b) are disposed near the recessed electrodes (1a) at the circuit board (1) in correspondence to each terminal. A mounting portion (4b) of each terminal (4) which is mounted at the circuit board (1), includes a first vertical portion (4c), a horizontal portion (4d) and a second vertical portion (4e) formed by bending the front end of the horizontal portion (4d). The first vertical portion (4c) is fitted at the recessed electrodes (1a) at the circuit board (1) and is then bonded to the circuit board (1) via a conductive bonding material. The second vertical portion (4e) is inserted at the through electrodes (1b) and is then bonded via a conductive bonding material.
Abstract:
A circuit board and method for populating, securing and electrical contacting of components thereon is provided, as an alternative to the known pressfit technology. After the soldering of SMD-components on a first side of a circuit board, conductive adhesive and solder paste are applied on a second side of the circuit board and a connection pin of a thermally critical THT-component is inserted into the special connection bore from the first side of the circuit board. Then, on the second side of the circuit board, SMD-components are set into the solder paste. In a reflow soldering oven, the SMD components are soldered and the conductive adhesive is dried and cured. By the binding effect of a metallizing sleeve of the connection bore, the insertion of the connection pin in the area of the a constriction produces a kind of cold weld connection, which, alongside the electrical connection by the conductive adhesive, represents a redundant connection, which accompanies the highly secure mechanical connection by the conductive adhesive.

A method for forming a recognition mark on the back surface of a substrate for a KGD that can be easily produced at a low manufacturing cost and permits repeated use of a substrate is provided. In the method, wiring patterns are formed on a surface of one side of an insulating substrate. The method includes a step of forming a conductive pattern as a recognition mark on one surface where the wiring patterns are formed, and a step of forming a through hole from a surface where the wiring pattern is not formed toward the conductive pattern. In the substrate, bumps connected with the KGD are formed on the surface on which the wiring patterns are not formed. Also, the conductive pattern may have a shape as the recognition mark or the through hole may have the shape as the recognition mark.
Abstract:
Disclosed is a novel deformation-resistant structure of a portable device, capable of reducing an electric failure by decreasing a distortion which occurs in a soldered portion between a printed circuit board of the portable device and an electric part mounted on the board due to a mechanical stress such as drop or pressure. Through slits are formed in positions in a printed wiring plate, which correspond to bosses having prepared holes disposed at the corners of a casing. By inserting screws into the prepared holes through the through slits, the printed circuit board is mounted in the casing. Although the casing is deformed when an external mechanical stress is applied to the casing, the screw and the boss can slide along each of the through slits. Thus, a deformation amount of the printed circuit board is not caused or becomes smaller than that of the casing.
