Abstract:
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 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 from the surface interconnect during the soldering process. The compliant pin may be soldered into place upon being coupled to the tapered surface interconnect.

A communication module may include a communication ground layer (338). The communication module may also include a circuit board (340). The circuit board (340) may be located proximate the communication ground layer (338). The circuit board (340) may include a stitch layer (346). The stitch layer (346) may be electrically coupled to the communication ground layer (338) via a plurality of stitch layer vias (348). Additionally, the communication module may include multiple ground vias (342). The ground vias (342) may be electrically coupled to a portion of the circuit board (340) and to the communication ground layer (338).
Abstract:
A contact tail for an electronic component compatible with surface mount manufacturing techniques. The contact tail is stamped, providing a relatively low manufacturing cost and high precision. High precision in the contact tails in turn provides more reliable solder joints across an array of contact tails in an electronic component. Further, the contact tail may be shaped to reduce the propensity for solder to wick from the attachment area during a reflow operation. Reducing the propensity of solder to wick reduces the chance that solder will interfere with the operation of the electronic component. Additionally, reducing the propensity for solder to wick allows pads to which the contact tail is attached to be positioned over vias, thereby increasing the density with which contacts may be attached to a substrate. The reliability with which electronic assemblies incorporating components using the contact tail is also increased when the contact tail is used in self-centering arrays.
Abstract:
Electromagnetic shielding devices are provided with walls having a pair of opposing, generally parallel side faces that terminate at a tapered end portion. Each tapered end portion is configured to be surface mounted to a respective conductive portion (e.g., mounting pad) of an electronic substrate via a pair of solder fillets. The tapered end portion of each wall includes a pair of elongate end faces symmetrical about a plane that is generally parallel to, and equidistant between, the wall side faces. The end faces define a pair of elongated cavities with respect to a PCB that are configured to receive the solder fillets.
Abstract:
First and second tapered holes are provided at facing positions of the first and second circuit boards. The elastic spacer including first and second spacers is attached between them to couple the two in parallel and thereby facilitate attachment of the two to a back panel. The first spacer is provided at one end part with a tapered part which fits with the first tapered hole and the second spacer is provided at one end part with a tapered part which fits with the second tapered hole. A spring is inserted between the two spacers. The first spacer is fit in the tapered hole and fastened by a screw to the first circuit board. The second circuit board is fastened by a screw to the first spacer in a state fitting the second tapered hole over the second spacer with the second circuit board approaching the first circuit board.
