Abstract:
A lead (12) of an electrical component (10) is formed with an arrowhead-shaped tip (20) that functions to mechanically fasten the lead and component to a substrate (14), such as a flexible printed circuit (11). The tip is formed with barbs (21) extending rearwardly from the end (22) of the tip and having a width (W) across the barbs greater than the diameter (d) of a mounting hole (13) in the substrate. With this arrangement, the barbed tips may be inserted into and through the hole, with the barbs being compressed relatively inward with respect to the hole as the tip passes through the hole, so as to fasten the tips to the substrate in preparation for a soldering operation, in which the tips are soldered (30) to conductive pad areas (16) deposited on the surface of the substrate adjacent to the tips.
Abstract:
To seat an electrical circuit element in a metallized opening of a circuit board and permit escape of solder gases, a bead is placed on the insertion pin and formed with a surface facing the support board which is non-symmetrical with respect to the axis of the pin, and of the insertion opening. Preferably, the surface is conical, and on adjacent pins the cone angles are tilted in opposite directions to provide for the non-symmetrical positioning of any one cone and centered placement of the insertion pins in the insertion openings.
Abstract:
The connection of an electrical component to a printed circuit board wherein a lead to the component includes an offset being in frictional engagement with the walls of an opening within the circuit board, the apex of the offset being soldered to be able to electrically connect the lead to the printed circuit path on the underside of the board, the free end of the lead extending exteriorly of the board on the upper surface thereof.
Abstract:
A staking electrical contact for staking an electrical conductor onto a printed circuit board and in electrical engagement with a printed circuit path on the printed circuit board which comprises a body portion having spaced legs between which the electrical conductor is disposed and the legs are driven into slot means of the printed circuit board until the contact is bottomed whereupon the free ends of the legs are bent into engagement with the printed circuit path and soldered thereto.
Abstract:
A semiconductor device package may include a substrate having an insulating layer with a patterned conductive layer formed thereon, the patterned conductive layer including at least a first pattern portion and a second pattern portion. The semiconductor device package may include a leadframe having a lead that is soldered to the substrate with solder provided in an opening between the first pattern portion and the second pattern portion and with the lead inserted into the opening.
Abstract:
An RF connector includes a conductive pin for carrying an RF signal. The conductive pin has a first longitudinal end that serves to interface with a male RF connector to receive the RF signal. The pin also includes a second longitudinal end for connecting with a printed circuit board (PCB). The second longitudinal end may be tapered, and the pin may have a groove formed above the tapered end. A housing encircles the conductive pin. The housing is shaped and sized to accept the male RF connector. A grounding element may be positioned on the bottom of the housing. The grounding element is to contact the PCB when the connector is connected to the PCB. The grounding element may be ring-shaped and soldered to the housing or epoxied to the housing.
Abstract:
