A method for inserting preformed solder members into connector pins for use with electrical connectors. The method generally includes a connector pin having an open cavity at one end, into which a preformed solder member can be first inserted and then pressed, rather than melted, in place, such that voids and air spaces within the cavity are substantially eliminated. The method allows for inserting solder members in high quantities, where the preformed solder members are placed in a fixture and the fixture is placed on a shaker table, so that solder members can be inserted into large numbers of connector pins that are pre-installed in connector grommets, largely simultaneously.

Printed circuit boards (PCBs) are configured with an athermalized mounting suitable for securing and positioning and the PCBs within an inertial measurement unit (IMU). The PCBs include integrated circuit (IC) components, such as accelerometers and/or gyroscopes, which require relative positional stability within the IMU environment in order to provide accurate results. The athermalized mounting configuration of the PCB enables the PCBs to experience thermal expansion within the IMU without causing significant displacement of the IC relative to the IMU environment.

A printed circuit board is provided. The board includes a plurality of vias through the printed circuit board, each having a first section with a first width, a second section with a second width less than the first width, and a third section with a third width greater than the second width and less than the first width. The second section is located between the first section and the third section, the first and second sections are plated, and the third section lacks plating. At least one of the plurality of vias has the first width dimensioned to receive a connector pin inserted through the first face. A further at least one of the plurality of vias has the first width dimensioned to receive a further connector pin inserted through the second face. Further versions of the printed circuit board and method of making a printed circuit board are provided.

In a composite component having a laminate body, a conductive layer and a connector can be joined to one another using an intermediate flexible circuit. Among other things, this flexible circuit places the conductive layer and the connector in electrical communication with one another. Furthermore, during the forming process and because of its thinness, the flexible circuit integrates well with the layers of the laminate body and can accommodates some spatial displacement of the connector and conductive material relative to one another.

An electronic apparatus includes a connection target member that has a first connection portion including copper or copper alloy, a connection terminal that has a second connection portion including copper or copper alloy, the second connection portion mechanically connecting with the first connection portion by spring reaction force of the connection terminal, and a joint portion that is provided with a contact point between the first connection portion and the second connection portion. At least one of the first connection portion and the second connection portion includes an oxide film at a periphery of the joint portion on a surface thereof, the oxide film including copper oxide. The joint portion directly joints copper included in the first connection portion and copper included in the second connection portion metallurgically.

An interposer includes a housing having a plurality of through-holes penetrating a first surface and a second surface and a signal contact pair composed of a pair of signal contacts. Each of the signal contacts includes a base portion press-fitted in one of the through-holes, a first contact beam extending from the base portion beyond the first surface, and a second contact beam extending from the base portion beyond the second surface. The pair of signal contacts are positioned adjacently to each other widthwise and are each asymmetrical with respect to a width direction. The signal contact pair has a plane-symmetrical shape with respect to the width direction.

Electrical contact arrangement for an electric motor and method for producing same. The present invention relates to an electrical contact arrangement for an electric motor, in particular for an EC drive of a motor vehicle fan, comprising an elongate contact which runs perpendicular to a planar basic conductor, wherein the basic conductor is in the form of a leadframe, and a conductive cohesive and/or form-fitting and/or force-fitting connection is provided between the leadframe and the contact. The present invention also relates to a method for the production of said electrical contact arrangement.
