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.

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.

A circuit board assembly may include a circuit board, a first electrical terminal, and a layer of solder paste. The circuit board may include a minimum thickness, a first side, and a second side opposite the first side. The first electrical terminal may include a solder tab. The layer of solder paste may be disposed on the first side of the circuit board. The solder tab of the first electrical terminal may extend into the first side of the circuit board but not beyond the second side of the circuit board.

The invention provides a spacer for soldering comprising an elongate body having one end provided with a tapped hole and an opposite end provided with a transverse bearing surface having a smooth centering peg projecting therefrom, the peg has a longitudinal outer passage extending over at least a fraction of its length as far as the transverse bearing surface to enable molten solder to penetrate by capillarity as far as the transverse bearing surface. The invention also provides a module including such a spacer.

In an embodiment a filter component includes a printed circuit board with an electrical circuit arranged thereon, a bus bar and a clamping plug-in connector, wherein the clamping plug-in connector, arranged on the printed circuit board, is electrically connected to the electrical circuit and is configured for electrically contacting the electrical circuit with the bus bar.

A method of assembling a circuit board may include inserting a first electrical terminal into a first side of a circuit board, and applying a second layer of solder paste to a second side of the circuit board, the second side disposed opposite of the first side. The first electrical terminal may include a solder tab, a maximum length of the solder tab may be shorter than a minimum thickness of the circuit board, and if the first electrical terminal is inserted into the circuit board, the solder tab may extend at least partially into the circuit board without extending entirely through the circuit board. One or more electrical terminals with short and/or long solder tabs may be inserted into the second side of the circuit board and/or one or more electrical components may be attached to second side of circuit board.

A semiconductor module includes a substrate having a first surface, a first contact pin and a second pin. A respective first end of the first contact pin and the second contact pin is mounted over the first surface of the substrate. A respective first section of the first contact pin and the second contact pin is configured to be connected to a printed circuit board (PCB). The first section of the first contact pin is insertable to the PCB with a first press-in force and the first section of the second contact pin is insertable to the PCB with a second press-in force. The first press-in force is different than the second press-in force. The first contact pin is provided in a central region of the substrate and the second contact pin is provided in a peripheral region of the substrate.
