An electronic device includes a press-fit terminal, an electronic component and a substrate. The substrate includes a first through hole, a second through hole and an inlay. The press-fit terminal is press-fitted in the first through hole. The second through hole is located between the first through hole and a part of the substrate at which the electronic component is mounted. The inlay is made of a metal material and press-fitted in the second through hole. The inlay restricts a strain in the substrate and restricts decrease of a holding force of the substrate holding the press-fit terminal.

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.

A bobbin provides secure attachment of a magnetic component to a printed circuit board. The circuit board includes a set of slotted apertures and a set of tubular apertures. The bobbin includes at least two pin rails and a plurality of standoffs proximate each pin rail. L-shaped pins are attached to one of the pin rails. Straight pins are attached to the other pin rail. The component further includes a core, and at least one winding. The L-shaped pins are shaped to pass through and slide within the set of slotted apertures. The L-shaped pins engage the bottom surface of the circuit board when the straight pins are inserted through the set of tubular apertures (i.e., in a secured position). In the secured position, the magnetic component is held in place against the top surface of the circuit board and provides a soldering area for mounting on the bottom surface.

A work machine including a flow device for flowing molten solder from under a circuit board, and a backup pin for supporting the circuit board from below while a lead of a leaded component is being inserted into a through-hole, which are moved separately under the circuit board. Thus, when the circuit board needs to be supported, the backup pin can be moved to any position, and when solder needs to be applied, the backup pin can be moved to a position that does not obstruct operation of the flow device. Accordingly, as well as guaranteeing operation of the flow device, it is possible to support the circuit board with the backup pin as required, thus improving practicality of the work machine.

The present disclosure provides a LED module. The LED module includes a LED lamp, a heat radiator, and a PCB. The LED lamp includes a LED main body, and a heat conducting block and a pin configured to the main body. The heat conducting block is mounted on the bottom surface of the LED main body towards the PCB. The pin has a free end passing through the PCB, and electrically connecting a bonding pad of the PCB. The heat radiator is caught between the heat conducting block and the PCB, and the heat conducting block resists against the heat radiator. A display device is also provided. The heat introduced by the LED lamp can directly dissipate from the heat conducting block to the heat radiator, thus enhancing the heat dissipation of the LED lamp.

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.
