An electronic device includes a printed circuit board having lands and an electronic element having a body and terminals. First and second lands provide a zigzag pattern. Each first land is coupled with the first terminal, and each second land is coupled with the second terminal. The second terminal includes a first parallel member, a first connection member, a second parallel member and a first mounting member. The first parallel member is completely embedded in the body, or another part of the first parallel member exposed from the body is shorter than the second parallel member. A second height between the second parallel member and the printed circuit board is smaller than a first height between the first parallel member and the printed circuit board.
Abstract:
An electronic component mounting structure includes a board and an electronic component mounted on a surface of the board. The board includes lands. The electronic component includes a body and terminals extending from the body. Each terminal is electrically connected to a corresponding one of the lands of the board. The terminal has a first terminal portion extending along the surface of the board and a second terminal portion extending toward the surface of the board. Each land includes a land portion electrically soldered to the first terminal portion and a blind hole for receiving the second terminal portion. The first terminal portion is soldered to the land portion in a reflow process under the condition that the second terminal portion is inserted in the blind hole.
Abstract:
An integrated circuit (IC) package 100 comprises an IC 102 and leads 104 coupled to the IC. Each lead has a first end 106 configured to be coupled to the integrated circuit and a second end 108 configured to pass through one of a plurality of mounting holes 110 extending through a mounting board 112. The leads comprise at least one positioning lead 114 comprising a stop 118 being a continuous part of the positioning lead and having a lateral dimension 120 greater than a diameter 122 of a first hole 124 of the plurality of mounting holes. The leads further comprise at least one non-positioning lead 116 having a continuous uniformly shaped body 130 with a lateral dimension 132 less than a diameter 134 of a second hole 136 of the plurality of mounting holes. The stop limits an extension of the non-positioning lead through the second hole.
Abstract:
A surface-mounted electronic component has an outer lead extending from a package for connection to a circuit pattern on a printed circuit board by using a connecting member. The outer lead has a hole having an opening at least on a connecting member facing side in a portion of the outer lead for connecting the outer lead to the circuit pattern.
Abstract:
An electromagnetic (EM) shielding assembly includes an electrically conductive shielding portion and one or more electrically conductive protrusions for engaging with respective conductive apertures in a circuit board. The electrically conductive protrusions can be in electrical communication with the EM shielding portion. The protrusions can enable the EM shielding assembly to be attached to a circuit board in a computer system while also providing an electrical connection to logical ground. Further components, for example a heat sink that may be in electrical communication with the EM shielding portion, may thereby also be connected to logical ground.
Abstract:
An electrical connector (10) of the type having an array of signal contacts (22) surface mountable to pads of a circuit board (20), with at least one ground bus (40) having a plurality of post sections (44,50,52) insertable into through holes (34) of the circuit board. At least two of the post sections (50,52) include protuberances (54,56) proximate free ends thereof adapted to bear against side walls of the respective through holes upon insertion thereinto, for deflection of the shanks (62,64) of the post sections in the opposite direction. The protuberance of each of the at least two post sections extends in opposed directions along the row of posts, thus cooperating to act as a clamp of modest force to retain the connector to the board prior to contact soldering. The deflectable shank (62,64) preferably has a reduced cross-sectional area at root (66,68) facilitating deflection in the plastic region.
Abstract:
A diode or other axial lead electronic component which requires mounting of its leads in a predetermined orientation is provided with leads of considerably different diameter. A printed circuit board is provided with holes sized to receive respective leads, so that the leads can be inserted into the holes only one way. Instead of having circular cross-sections and different diameters, one lead may have a circular cross-section while all or an end portion of the other lead has a non-circular cross-section with a diameter allowing that lead to fit in only the larger hole of the printed circuit board.
Abstract:
An electronic component is provided having mounting leads configured as concentric arcs centered about a desired axis of rotation. The leads may therefore be inserted into a mounting board, and the component rotated to a desired angle with respect to the surface of the mounting board. In some embodiments, one or more of the mounting leads is provided with tabs or other positioning elements to facilitate the positioning of the component at any of a number of selected angles relative to the mounting board.
