An electronic device where molten solder does not come into contact with a sealant so as not to destroy a sealing function. An electronic device is provided with: an insulating base mounted on a printed circuit board; a common planar terminal provided so as to extend from an outer side surface to a bottom surface edge of the insulating base, and cause electrical continuity between the outer side surface and the bottom surface edge of the insulating base; a cover fitted to the insulating base and covering the common planar terminal; and a sealant sealing a gap between the outer side surface of the insulating base and an inner circumferential surface of the cover. A solder pool is formed in a position surrounded by the printed circuit board and the common planar terminal at the bottom surface edge of the insulating base.

Provided is a substrate terminal-equipped printed circuit board having configured to enable a substrate terminal to be fixed to a printed circuit board without using a pedestal, and to reduce the pressure and the insertion force applied to an inner surface of a through hole when the substrate terminal is press-fitted therein. A conducting portion of a substrate terminal includes: a press-fitted portion disposed at a proximal end portion thereof and is press-fitted into a through hole; and a loosely inserted portion that extends from the press-fitted portion to a distal end portion thereof, has a narrower width than the press-fitted portion, and is inserted into the through hole with a gap therebetween, and the press-fitted portion of the conducting portion is in pressure contact only with printed wiring provided on a surface layer of the printed circuit board and with an insulating layer located immediately below the printed wiring.

A socket housing and contact assembly process includes forming the solder ball contact region after initial installation of a set of contacts into the housing. The contact regions of the set of contacts pass through corresponding contact cavities to extend beyond the housing and the contact regions are formed over at equal angles for solder ball placement.

An assembly is provided. The assembly includes a component, a solder pin arranged on the component, an electrical structural unit, and a soldering point which is arranged on the electrical structural unit and forms an opening, into which the solder pin is insertable along an insertion direction in order to produce a soldered joint. The solder pin has an insertion portion which, on sides of the solder pin that face away from each other, forms insertion walls which are arranged at an acute angle to one another in such a way that the insertion portion tapers in the insertion direction. A part of the insertion portion is arranged outside the opening in such a way that one or more portions of the insertion walls extend inside the opening and one or more portions of the insertion walls extend outside the opening.

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.

According to exemplary embodiments, a tapered surface interconnect is formed on a printed circuit board (PCB). A compliant pin of an electrical connector may be coupled to the tapered surface interconnect and soldered thereto. The surface interconnect may be formed by drilling through one or more layers of the PCB. The depth of the surface interconnect may be shorter than a height or a thickness of the PCB. The surface interconnect may have a tapered side wall to allow for a better fit with a tapered compliant pin. The inclination of the side wall of the surface interconnect may be linear or concave. The intersection between the tapered sidewall and the bottom of the surface interconnect may be rounded to minimize pin insertion issues and may allow for easier solder flux evacuation. The compliant pin may be soldered into place upon being coupled to the tapered surface interconnect.
