Abstract:
An electrical contact assembly that uses an elastomer strip for each row of individual contacts. Each contact comprises a rigid bottom pin and a flexible top pin with a pair of arms which extend over and slide along sloped surfaces of the bottom contact. The elastomer strip is located between rows of the bottom and top pins. A bottom socket housing is provided with grooves which receive each elastomer strip. A row of top pins is then placed over each elastomer strip, and through ducts in the bottom socket housing. Bottom pins are then snapped into place in between the pair of arms.
Abstract:
An electronic device includes a base body, which has a top side and also an underside lying opposite the top side. The base body has connection locations at its underside. An electronic component is arranged at the base body at the top side of the base body. The base body has at least one side area having at least one point of inspection having a first region and second region. The second region is embodied as an indentation in the first region. The first and the second region contain different materials.
Abstract:
A structure of a light emitting diode is provided. In one aspect, a light emitting diode structure comprises a light emitting diode, a conductive frame, and a substrate. The conductive frame is electrically connected to the light emitting diode and has a fixing hole connecting a first side of the conductive frame and a second side of the conductive frame opposite the first side. The fixing hole has a ladder-shaped inner sidewall with a first radius of the inner sidewall adjacent the first side smaller than a second radius of the inner sidewall adjacent the second side. The substrate has a conductive pillar that is received in the fixing hole by entering the fixing hole from the first side of the conductive frame and deformed such that the conductive pillar adheres to the ladder-shaped inner sidewall of the fixing hole.
Abstract:
A method of fixing reflowable elements on electrical contacts. The method includes providing a strip having a number of electrical contacts, each contact including a contact body and a tail portion extending away from the contact body. The tail portions of the contacts are then disposed adjacent an elongate reflowable member. The elongate reflowable member is pushed onto the tail portions of the plurality of contacts. Subsequently, the elongate reflowable member is cut into a plurality of separate reflowable elements, each reflowable element corresponding to one of the tail portions. The electrical contacts with the reflowable element attached thereto are separated from the strip.
Abstract:
A circuit module includes a substrate, a component land provided on the substrate, an electronic component bonded to the component land, a case land provided on the substrate, and a case bonded to the case land so as to cover the electronic component. The case includes a top plate, and a leg that extends from a peripheral edge of the top plate in a direction substantially perpendicular to the top plate and that includes a groove in an end surface thereof that is bonded to the case land.

Abstract:
The invention relates to a first component (12, 13, 31, 36a-36c, 50, 62) intended for being connected to a second component (14, 15, 51, 63a-63c). The first component (12, 13, 31, 36a-36c, 50, 62) comprises at least one recess (16, 17, 32, 37a-37c, 52a-52c, 64a-64c) having at least one opening (19, 20, 34, 35, 54a-54c) which will be filled at least in part by the second component (14, 15, 51, 63a-63c) which latter is in a flowing condition during establishment of the connection, at least in the area of the opening (19, 34, 54a-54c). A reduction in cross-section (18, 33, 38a-38c, 53a-53c, 65a-65c) is provided in the recess (16, 17, 32, 37a-37c, 52a-52c, 64a-64c) that will be back-filled by the second component (14, 15, 51, 63a-63c) during establishment of the connection. The reduction in cross-section (18, 33, 38a-38c, 53a-53c, 65a-65c) is provided in the recess (16, 17, 32, 37a-37c, 52a-52c, 64a-64c) on the side facing the second component (14, 15, 51, 63a-63c).
Abstract:
A socket connector is bonded to a circuit board by solder materials. The solder materials are well arranged so that no short circuits occur. The socket connector can be applied in a wide range of uses with high yield and reduced cost. The socket connector has an insulative housing having a plurality of terminals and a solder material therein. The socket connector is characterized by the insulative housing being provided with a plurality of overflow holes in a direction along which the insulative housing and terminals apply pressure to the solder material.
