An interface card fixing device adapted to fix an interface card to a main board is provided. The interface card fixing device includes a base, a fixing portion, an engaging portion and a connecting portion. The base includes a first surface and a second surface opposite to each other and a protrusion protruding from the first surface. The base has a through hole passing through the first surface, the second surface and the protrusion so that the protrusion forms a hollow cylinder. The fixing portion extends from the second surface of the base and includes a breach communicating with the through hole. The engaging portion is adapted to pass through the through hole and the breach, and fix to the base. The connecting portion is connected to the base and the engaging portion. A main board module having the interface card fixing device is further provided.

A test socket for a semiconductor integrated circuit (IC) is provided. The test socket includes a socket body configured to engage the semiconductor IC and a load board and an elastomer retainer including a top surface adjacent to the socket body and configured to face the semiconductor IC, and a bottom surface configured to face a load board. The elastomer retainer defines a slot extending from the top surface to the bottom surface. The test socket further includes a rotational contact positioned in the slot. The rotational contact is configured to move between a free state, a pre-load state, and a loaded state. The elastomer retainer is configured to compress under a pre-load force from the rotational contact when moving from the free state to the pre-load state, and compress under a loading force from the rotational contact when moving from the pre-load state to the loaded state.

A chip carrier for carrying an electronic chip, wherein the chip carrier comprises a mounting section configured for mounting an electronic chip by sintering, and an encapsulation section configured for being encapsulated by an encapsulant.

Disclosed is a socket apparatus for ball grid array (BGA) balls, including a base member of electrically insulative material, a plurality of electrical contact members disposed in row and column configuration attached to the electrically insulative material, a plate member extending in a row direction, and a plurality of extension members connected to the plate member and configured to press BGA balls of a mounted BGA into the plurality of electrical contact members when the plate member is pulled in a first direction.

An electrical connector and the buckle assembly thereof. The buckle assembly includes a stiffener provided with a frame opening for receiving an insulating body of the electrical connector, and a load plate with a rear end pivoted to the stiffener. The stiffener has a reinforce rib in front of the frame opening. The reinforce rib has a raised portion protruding upward from an upper surface of the stiffener, and an extending portion is formed by horizontally extending from the raised portion. The load plate has a through hole for receiving the chip module, a receiving hole in front of the through hole, and two receiving holes behind the through hole. Each receiving hole allows a locking member to pass therethrough to fix the load plate onto the stiffener.

An electrical connector and a clamping member thereof. The electrical connector includes an insulating body, multiple terminals fixed to the insulating body, a stiffener surrounding a periphery of the insulating body, a load plate, and a clamping member located between the load plate and the stiffener. A grasping portion protrudes forward from the clamping member. The grasping portion has two first sections provided at each of two opposite sides thereof, two second sections formed by respectively turning and extending forward from the two first sections to be close to each other, two third sections formed by respectively turning and extending forward from the two second sections, and a head formed by extending from the third sections. A distance between the two first sections is greater than a distance between the two third sections, and a width of the head is greater than the distance between the two third sections.

An adapter apparatus and method includes using an adapter body defining a socket cavity configured to receive a packaged device and a torque applicator configured to apply an axial force. A bearing structure positioned between the torque applicator and a packaged device may be used to transfer a force (e.g., an axial force) applied using the torque applicator to the packaged device.

An electrical connector and the buckle assembly thereof. The buckle assembly includes a stiffener for receiving a socket, a load plate for pressing the chip module, and a guide frame pivoted to the stiffener. A rear end of the load plate is pivoted to the stiffener. The guide frame has an opening for receiving the chip module, and two side arms located on two opposite sides of the opening and a rear arm connected to the two side arms. Each of the side arms is provided with a sliding rail for carrying a side plate of a clamping member. The side plate is slidable along the sliding rail. The clamping member is used for fixing the chip module. A protruding portion is formed by protruding upward from the sliding rail, making the protruding portion higher than the sliding rail.

An electrical connector and the buckle assembly thereof. The buckle assembly includes a stiffener provided with a frame opening for receiving an insulating body of the electrical connector, and a load plate with a rear end pivoted to the stiffener. The stiffener has a reinforce rib in front of the frame opening. The reinforce rib has a raised portion protruding upward from an upper surface of the stiffener, and an extending portion is formed by horizontally extending from the raised portion. The load plate has a through hole for receiving the chip module, a receiving hole in front of the through hole, and two receiving holes behind the through hole. Each receiving hole allows a locking member to pass therethrough to fix the load plate onto the stiffener.

An electrical connector and a clamping member thereof. The electrical connector includes an insulating body, multiple terminals fixed to the insulating body, a stiffener surrounding a periphery of the insulating body, a load plate, and a clamping member located between the load plate and the stiffener. A grasping portion protrudes forward from the clamping member. The grasping portion has two first sections provided at each of two opposite sides thereof, two second sections formed by respectively turning and extending forward from the two first sections to be close to each other, two third sections formed by respectively turning and extending forward from the two second sections, and a head formed by extending from the third sections. A distance between the two first sections is greater than a distance between the two third sections, and a width of the head is greater than the distance between the two third sections.
