Abstract:
An electrical connector includes: an insulative housing defining a front mating cavity; a mating tongue extending into the front mating cavity and defining thereon first and second mating faces opposite to each other, said mating tongue dividing said mating cavity into a first mating space confronting the first mating face for mating with a first complementary connector, and a second mating space confronting the second mating face for mutually exclusively mating with second and third complementary connector; a plurality of first type contacts disposed on the first mating face for connecting with the first complementary connector, a plurality of second type contacts disposed on the second mating face for connecting with the second complementary connector, and a plurality of third type contacts located between the first type contacts and the second type contacts with front ends of the third type contacts exposed to the second mating space.
Abstract:
A flip chip semiconductor package is disclosed according to the present invention, the flip chip semiconductor package comprises a chip that is mounted on and electrically connects to a leadframe via a plurality of solder bumps by means of flip chip, and an encapsulate that encapsulates the chip, the plurality of solder bumps, and the leadframe, wherein, the leadframe further comprises a plurality of leads and a ground plane that is located between the plurality of leads, and also a slit is formed on the ground plane, and then a molding compound that makes up the encapsulant should be capable of filling within the slit, thus to enhance the adhesion between the ground plane and the encapsulant, and then avoid delamination between the ground plane and the encapsulant in subsequent thermal cycle processes, thereby increasing the reliability of fabricated products.
Abstract:
A keyboard. The keyboard comprises at least one key, a base, a membrane assembly and a circuit board. The membrane assembly is disposed between the base and the key. At least part of the circuit board is disposed in the key. The keyboard is connected to a notebook computer or a personal computer via a connection member.
Abstract:
An electrical connector includes an insulative housing defining a mating cavity, two parallel and stacked mating portions respectively forwards extending into the mating cavity, sets of contact retained in the housing and a grounding member retained in the housing. The first mating portion defines thereon a first surface; the second mating portion spaces from the first mating portion and defines thereon a second surface opposite to the first surface. The sets of contact include a first set of contacts each defining a contacting section exposed upon the first surface and a second set of contacts each defining a deflectable cantilevered beam accessible from the second face. The grounding member is disposed between the first and second mating portions to reduce the cross-talk between the first and second sets of contacts.

Abstract:
An electrical connector assembly includes an insulating housing, a plurality of first contacts received in the insulating housing, at least one detecting pin and a controlling circuitry. At least partial first contacts unitarily includes first contacting portions transferring first data signals and second contacting portions transferring second data signals. The detecting pin produces two sets of different detecting signals corresponding to the first data signals and the second data signals. The controlling circuitry controls said data signals output data signals through different output terminals.
Abstract:
An electrical connector includes an insulative housing having a mating cavity, a tongue portion extending into the mating cavity and defining thereon first and second faces opposite to each other, and a plurality of contacts retained to the housing. The plurality of contacts defines a first and second set of contacts and expanded contacts. The first set of contacts each defines a first blade contacting section exposed onto the first face, the second set of contacts each defines a deflectable cantilevered beam exposed onto the second face, and the expanded contacts include at least one power contact for power transmission. The at least one power contact defines a second contacting section arranged between two adjacent cantilevered beams and projecting out of the second face.
Abstract:
An information handling system circuit board has an opening formed through it proximate a coupling point of an integrated circuit to the circuit board. The opening manages stress at the coupling point of the integrated circuit to the circuit board to reduce the risk of damage to the coupling point during deformation of the circuit board, such as when the circuit board is coupled to a chassis or when a component is pressed into the circuit board. In one embodiment, rectangular openings are formed at diagonally opposed corners of a BSA integrated circuit. In alternative embodiments, openings of varying shape, such as slots or curved slots, are formed at selected corners of the integrated circuit.
Abstract:
A touchpad comprises a first insulating layer and a second insulating layer. The first insulating layer has a sensor surface and a plurality of metal sensors disposed on the sensor surface. The second insulating layer has a touch surface and a connecting surface. The connecting surface is opposite to the touch surface and covers the metal sensors. An electronic product comprises a main body and a touchpad. The main body has an exterior. The touchpad is disposed in the main body and exposed to the exterior of the main body. A method for forming a touchpad comprises locating a plurality of metal sensors on a sensor surface of a first insulating layer, and then connecting the first insulating layer and a second insulating layer, with the metal sensors sandwiched between the first insulating layer and the second insulating layer.
