Abstract:
A printed circuit board (PCB), which can be implemented on a battery set, having a plurality of soldering holes thereon. A soldering portion and a non-soldering portion are separately arranged around each of the soldering holes on both surfaces of the PCB. Each corresponding conductive stick can respectively pierce each soldering hole and be fixed to each soldering portion of the PCB with the fused solder or move from the soldering portion to the non-soldering portion in the soldering hole. Thus, this invention provides a convenient and efficient way for assembling the PCB on the battery set or disassembling the PCB apart from the battery set.

In a lead mounting method of mounting, onto a principal surface of a printed board, a lead to be connected to a terminal, a flat lead is prepared which lead has a mounted part to be disposed on the principal surface of the printed board and a connected part to be connected to the terminal. The flat lead is bent into an L shape so that the mounted part and the connected part are perpendicular to each other to obtain an L-shaped lead. The mounted part of the L-shaped lead is connected and fixed onto the principal surface of the printed board by soldering.

The present invention relates to a connector system for resiliently attaching and electrically connecting an integrated circuit chip to a circuit board using a plurality of leads. Each of the plurality of leads are sized and arranged to form a curved body having a first leg and a second leg with a curved portion between the first leg and the second leg. The curved body of the leads may be C-shaped in accordance with the present invention. The plurality of leads may be formed from strips of copper foil or copper mesh folded to form the curved body. The plurality of leads may also be sized and arranged to support the integrated circuit chip in a generally flat arrangement relative to the circuit board with a maximum separation of about 0.016 inches or less between the integrated circuit chip and the circuit board.

Abstract:
In a two-pole SMT miniature housing in leadframe technique for semiconductor components, a semiconductor chip is mounted on one leadframe part and is contacted to a further leadframe part. The further leadframe part is conducted out of the housing in which the chip is encapsulated as a solder terminal. No trimming or shaping process is required and the housing is tight and is capable of further miniaturization. The solder terminals as punched parts of the leadframe are conducted projecting laterally from the housing sidewalls residing opposite one another at least up to the housing floor which forms the components' mounting surface. The chip mounting surface and the components' mounting surface form a right angle with one another.
Abstract:
The invention is directed to techniques for forming a soldered connection using a pin having a channel. The channel enables the pin to form a secure connection with a via (e.g., by facilitating gas percolation out of the via hole during soldering to improve solder flow, by holding solder prior to pin insertion and soldering, or by facilitating accurate pin bending to hold solder or a pin insert prior to pin insertion and soldering) to improve connection system reliability and increase manufacturing yields. In one arrangement, the pin has a surface which includes (i) a first surface area, (ii) a second surface area that is substantially parallel to the first surface area, and (iii) a channel surface area which defines a channel that extends from the first surface area toward the second surface area. To form a soldered connection, the pin is inserted into a cavity defined by a via of a connecting member (e.g., a circuit board), in a direction that is parallel to a central axis of the via. The pin is then soldered to the via to establish an electrical pathway between the pin and the via. Depending on the particular arrangement, the channel generally facilitates the introduction of solder into the cavity of the via. Accordingly, the cavity dimension of the via can be smaller than that required for vias of a conventional reflow soldering approach (i.e., less than 100% of the maximum pin cross-section as for a conventional reflow soldering approach). Hence, the invention is suitable for use in high-density, micro-soldered connection arrangements (e.g., in situations with vias closer together than in the conventional reflow soldering approach).

Abstract:
An interchangeable printed circuit board having electrical components is attached externally proximate to the base of a switch to customize switch performance. The circuit board includes openings which slide over and electrically engage the terminals of the switch proximate the base, leaving the remainder of the terminals exposed and available for plug-in or solder electrical connection within an electrical system. The openings may be copper contact members having fingers which engage and electrically connect to the switch terminals.
