A wire harness assembly including a first connector, a second connector, and conductors extending between the first connector and the second connector. Contacts are provided on the second connector. The contacts have termination sections which are mounted on the second connector, compliant sections which extend from the termination sections, and substrate engagement sections which extend from the compliant sections. The substrate engagement sections have curved contact sections which are configured to be positioned in mechanical and electrical engagement with circuit pads of a mating printed circuit board. Embossments are provided on the curved contact sections to provide additional strength and stability to the curved contact sections.

An electrical connector used to be electrically connected to a chip module includes a body provided with multiple accommodating holes running through the body and at least one accommodating grooves. Each accommodating groove is formed between two adjacent accommodating holes to communicate the two adjacent accommodating holes with each other. Multiple terminals are correspondingly accommodated in the accommodating holes respectively. Each terminal includes a base and an elastic portion bending and extending upward from the base, and the elastic portion upward abuts the chip module. Each accommodating groove correspondingly accommodates the base of one of the terminals. Each accommodating groove is used for lowering strength of the body. When the electrical connector is soldered to a circuit board by high-temperature heating, the body is prone to be softened under the high temperature and thus becomes smooth, such that warping occurring during forming of the body is eliminated.

An electrical spring contact is provided. The electrical spring contact includes a connection portion configured to couple the electrical spring contact to a printed circuit board, a bulge portion, a bend portion having a substantially U-shaped configuration, and an inclined portion extending from the bend portion at an angle relative to a plane that is substantially parallel to the connection portion. The connection portion, the bulge portion, the bend portion, and the inclined portion are formed from a single conductive contact material.

An electrical connector includes an insulative housing and a plurality of contacts retained in the housing. Each of the contacts includes a vertical main body with retaining structure thereon, a mounting section split from the bottom portion of the main body with a horizontal pad at the end, a first transverse section extending from the top portion of the main body in a first transverse direction, an upward section extending upward from one end of the transverse direction, a second transverse section extending from an upper end of the upward section in a second transverse direction opposite to the first transverse direction, a curved contacting section extending from the end of the second transverse section, and a downward tip section formed at a free end of the contact section.

Provided is a speaker, including a holder, a pad fitted in the holder, and a conductive terminal. The conductive terminal comprises a fixed portion fitted into the holder, an elastic arm, and an engaging portion, an electrical connection portion. The elastic arm comprises an arc-shaped conductive portion connected to the fixed portion, and an extending portion connecting the arc-shaped conductive portion and the electrical connection portion. The arc-shaped conductive portion is spaced apart from the holder and protruding from the holder, the extending portion extends from the arc-shaped conductive portion towards the holder, and an end of the extending portion facing away from the arc-shaped conductive portion is attached to the holder. The engaging portion extends from an edge of an end of the extending portion facing away from the arc-shaped conductive portion while being bent towards the holder, and is engaged in an engaging groove of the holder.

An electrical connector includes an insulating body and multiple terminals. The insulating body has multiple terminal holes running through an upper surface and a lower surface thereof. Each terminal has a connecting portion correspondingly located in a corresponding terminal hole, a conducting portion extending from the connecting portion, an elastic arm formed by bending upward and extending from the connecting portion upward out of the corresponding terminal hole, and a contact portion bending upward and extending from the elastic arm. When a chip module is pressed downward, a bottom surface of each conductive sheet of a circuit board downward abuts a top surface of the contact portion, and the elastic arm deforms downward. The contact portion, the elastic arm, the connecting portion and the conducting portion are integrally formed. A thickness of the connecting portion is greater than a thickness of the contact portion.

An electrical connector for electrically connecting a chip module to a circuit board includes an insulating body, and a plurality of terminals. Each of the terminals has a base accommodated in the insulating body and a mating portion contacting a conductive sheet of the chip module. A plurality of supporting portions extend upward from an upper surface of the insulating body, and an upper end of each of the supporting portions is provided with a crumple portion located below the mating portion of one of the terminals. The chip module is mounted on the electrical connector, the conductive sheet presses the mating portion, the mating portion abuts the crumple portion, and the crumple portion is pressed so that a height of the crumple portion is decreased.

A spring connector includes a movable pin, a conductive tube accommodating a base portion of the movable pin, a spring provided in the conductive tube so as to urge the movable pin in a direction, in which the movable pin protrudes from the conductive tube, and a plate spring contact including a plurality of plate springs that electrically connect the movable pin and the conductive tube to each other. The plurality of plate springs are provided around an entire circumference of the movable pin and are in elastic contact with an inner circumferential surface of the conductive tube, respectively.

An electrical connector includes an insulating housing, a number of terminals and a lossy member. The terminals include a number of ground terminals and a number of signal terminals. The ground terminals and the signal terminals are set adjacently to each other but do not contact each other. The ground terminals do not directly contact the lossy member. As a result, installation consistency of the ground terminals can be achieved, thereby improving the electrical performance of the electrical connector.

Provided are improved manufacturing methods of semiconductor devices, probe cards, test apparatuses including the probe card, and methods for manufacturing probe cards. The probe card includes a circuit board, a support located under the circuit board, and a plurality of probe needles located on a bottom surface of the support. Each of the probe needles has a tip configured to contact a side surface of a bump included in a test target. The support may include a stress absorption layer located on a bottom surface to which the probe needles are connected. Manufacturing of semiconductor devices may comprise forming elongated conductive bumps on a body of a semiconductor device, testing the semiconductor device by contacting tips of the probe needles to sides surfaces of the bumps and packaging of the semiconductor device.
