摘要:
A connector for microelectronic elements includes a sheet-like body (3) having a plurality of holes (36), desirably arranged in a regular grid pattern. Each hole is provided with a resilient laminar contact (38) having a plurality of projections (42) extending inwardly over the hole in the body. Microelectronic elements (68) having bump leads (70) such as solder balls thereon may be engaged with the connector by advancing the bump leads into the holes of the connector to engage the bump leads with the contacts. The assembly can be tested, and if found acceptable, the bump leads can be permanently bonded to the contacts.

The invention relates to an assembly comprised of a panel-like constructed electrical/electronic module (7) comprising a flat surface with exposed, contactable connection sections AS serving as a part of an essentially flat conductor track structure for electrically connecting the module (7). The assembly also comprises a connection unit (1) provided with electrical/electronic elements D, which are located on a conductor track structure (2) situated in a plane parallel to the conductor track structure of the module (7). In addition, the assembly is fitted with means for contacting connection sections of the module whereby enabling the module to be electrically connected via the connection unit. The means for contacting the connection sections AS of the module (7) are bent out from the plane of the conductor track structure (2), and are connection sections AA that represent a portion of the conductor track structure. The connection sections AS of the module (7) are rigid and are electrical conductor sections AS that can be bent out from the plane of the conductor track structure of the module (7). Connection sections AA of the connection unit (1) are arranged according to the arrangement of connection sections AS of the module (7) so that when the connection unit (1) is connected to the module (7), one connection segment AS of the module (7) and one of the connection unit (1) are electrically connected to one another, abut against one section, and, in the area in which they abut, are situated in a spatial position different from that of the planes of the conductor track structures (2).

The invention relates to a method and device for connecting the electrical conductors which are surrounded by outer insulation and associated with overlapping flat conductors (47, 49) by means of a sonotrode (52) producing ultrasonic vibrations and a counter electrode associated therewith. The conductors which are to be connected are to be arranged on a surface (48) of a carrier (50) extending between the sonotrode and the counter electrode. The carrier can be embodied as a counter electrode.

A low cost Hall position sensor comprises a standard surface mount Hall effect sensing device (2) having its three leads (4, 6, 8) soldered directly to an exposed electro-conductive end portion of a standard flexible multiconductor circuit (42). The flexible circuit (42) may be custom designed and manufactured at low cost for a variety of mass production applications. The position sensor further comprises a permanent movable Hall magnet (82) disposed proximate to the soldered Hall effect sensing device which remains stationary during operation. The Hall effect sensing device (2) picks up variations in the magnetic flux generated by the movement of the Hall magnet during operation and sends a corresponding feedback voltage signal to an external controller which powers the Hall effect sensing device via the flexible circuit (42). The flexible circuit (42) has a second exposed electro-conductive end portion (46) for removably mating with a corresponding flex circuit connector on the controller board. The Hall position sensor may be used in applications involving a moving Hall effect sensing device (406) disposed proximate to a series of stationary Hall magnets (404a-404k).

The invention relates to a method for producing an electrical connection between a first contact partner part and a second contact partner part. According to the invention, the two parts are brought together and then interconnected non-detachably in a positive material fit or quasi- positive material fit, to form a plug-in connection.
摘要:
In a stator winding method and a stator winding structure, the ends (4a) of windings (4) are caused to become entangled with terminals (6) through a longitudinal rod member (10) and form slack portions (4aA) when the longitudinal rod member is removed, whereby the vibration resistance and impact resistance of the windings can be improved as well as preventing breakage thereof.

A solder-bearing lead (10) for attachment to the surface of a substrate (39), wherein a discrete mass of solder (24) is mechanically held firmly by the lead (10) in a position permitting close proximity to the substrate surface to connect the lead (10) to the substrate (39) with an electrical and mechanical bond upon melting of the solder (24), the lead body having a pair of fingers (22) partially encircling the solder mass (24) with a gap (32) between the fingers (22) providing an unobstructed flow for the melted solder to the substrate. The lead may also be used to interconnect a first substrate (39) to a second substrate (44), forming a bond between conductive areas (45, 46) on both substrates.
