Abstract:
A surface mount electrical connector includes a terminal body having a first elongate member that cooperates with a housing to secure the terminal body to the connector housing. A second elongate member of the terminal body includes a curved portion having an aperture therethrough. The curved portion includes a convex surface that facilitates automated assembly operations, and the aperture helps to overcome surface tension in liquid solder, thereby promoting a secure electrical connection.
Abstract:
A semiconductor device comprises a semiconductor element and electrodes electrically connected to the semiconductor element, the semiconductor element and the electrodes being sealed by a sealing agent having an insulating property, the electrodes being exposed around a mounting surface that is joined via a joining agent to an external mounting circuit board, wherein the electrodes are shaped so that the joining agent is visually identifiable from side surfaces surrounding the mounting surface when the mounting surface is joined via the joining agent to the mounting circuit board.
Abstract:
Lands formed on a flexible printed circuit board are electrically connected with lands formed on a rigid printed circuit board through solder. At this point, solder resist is formed between neighboring two lands on the rigid printed circuit board, and is terminated with an end portion that is interposed between the rigid printed circuit board and the flexible printed circuit board. Accordingly, even when surplus solder is extruded onto the rigid printed circuit board, the solder resist can prevent solder bridges from being formed between the lands.
Abstract:
A method and apparatus for engaging electrical components to a circuit board. The body of the component has at least one fastener integrally formed therewith. The at least one fastener includes a neck portion engaged to the body of the component and extending to a hook portion. The fastener is configured to reside substantially within a through-hole formed in a circuit board. The through-hole in the circuit board has a solder lining, and the fastener is placed into the through-hole. The solder is reflowed via known soldering techniques so that the hook portion of the fastener is engaged by the reflowed solder, thus engaging the component to the circuit board.
Abstract:
A solder-bearing metallic lead, and methods of fabricating and using it, where the lead is formed with a solder-retaining portion having a cross-sectional profile with undercuts, which may be in a V-shape or flat, where solder surrounds said solder-retaining portion and undercuts, and extends outwardly from the lead while leaving a portion of the lead uncovered by solder to permit the lead metal to form direct contact with a substrate or other conductive pad.
Abstract:
A surface-mount integrated circuit converter board assembly having a pin grid array arranged enables a conventional surface-mount lead device to be mounted for subsequent attachment to a printed circuit board. The converter board assembly includes an array of spaced apart pins, arranged in rows and columns for mounting, and a plurality of spaced apart pin pads connected thereto. The pin pads are sufficiently spaced apart to avoid interference. A set of surface-mount lead pads is part of the converter board and is interconnected to the array of pins by a plurality of lead traces. The method of making the converter board with a surface-mount integrated circuit device includes forming or reforming the leads of the device to align with the surface-mount pads.
Abstract:
An improved brazing structure is disclosed in which at least a tip end portion to be brazed of a lead is bent and this tip end portion is bonded to a metallized layer by a brazing material substantially in perpendicular to the plane of the metallized layer.
Abstract:
A surface-mounted electronic component (10) has an outer lead (12) extending from a package (11) for connection to a circuit pattern (21) on a printed circuit board (20) by using a connecting member (30). The outer lead (12) has a hole (12b) having an opening at least on a connecting member (30) facing side in a portion (12a) of the outer lead (12) for connecting the outer lead (12) to the circuit pattern (21).
