Abstract: A circuit board structure includes a carrier, a thin film redistribution layer disposed on the carrier, solder balls electrically connected to the thin film redistribution layer and the carrier, and a surface treatment layer. The thin film redistribution layer includes a plurality of pads, a first dielectric layer, a first metal layer, a second dielectric layer, a second metal layer, and a third dielectric layer. A plurality of first openings of the first dielectric layer expose part of the pads, and a first surface of the first dielectric layer is higher upper surfaces of the pads. The solder balls are disposed in a plurality of third openings of the third dielectric layer and are electrically connected to the second metal layer and the carrier. The surface treatment layer is disposed on the upper surfaces, and a top surface of the surface treatment layer is higher than the first surface.

Abstract: Semiconductor processing apparatuses and methods are provided in which an electrostatic discharge (ESD) prevention layer is utilized to prevent or reduce ESD events from occurring between a semiconductor wafer and one or more components of the apparatuses. In some embodiments, a semiconductor processing apparatus includes a wafer handling structure that is configured to support a semiconductor wafer during processing of the semiconductor wafer. The apparatus further includes an ESD prevention layer on the wafer handling structure. The ESD prevention layer includes a first material and a second material, and the second material has an electrical conductivity that is greater than an electrical conductivity of the first material.

Abstract: An apparatus having a first portion including a first front wall, a first rear wall, and a bottom wall integrally coupled to the first front wall and the first rear wall, and pivotal pin structures integrally coupled to and extending from the first rear wall. The apparatus includes a second portion having a second front wall, a second rear wall, and a top wall integrally coupled to the second front wall and the second rear wall, and pin holders integrally coupled to and extending from the second rear wall and at an offset angle with reference to the top wall. The pivotal pin structure includes a base support connected to the first rear wall and a shaft connected to the base support, and the pin holder defines an opening sized and shaped to accept the shaft. The first and second portions are sized and shaped to be pivotally movable between open and closed configurations.

Abstract: A fastening mechanism includes a nosepiece, a rotating unit, a torsion spring and a locking unit. The nosepiece is disposed at one side of an object removably disposed in a housing. The rotating unit includes a wheel body including a peripheral wall with an outer peripheral friction surface disposed in frictional contact with a side surface of the nosepiece and a rotating disc formed with a notch. The rotating unit is operable to rotate in a releasing direction relative to the housing as biased by the torsion spring to move the object away from the housing through an opening by virtue of the frictional contact. The locking unit releasably engages the rotating disc to dispose the rotating unit at a stopped position.

Abstract: A circuit board device for fixing an electronic card, which is formed with at least one aperture, includes a circuit board and a securing member. The circuit board includes a board body formed with two through holes, and a socket connector provided on the board body for mating with the electronic card. The securing member includes a pressing plate for pressing against the electronic card, at least one engaging stud projecting from a bottom end of the pressing plate for engaging the aperture, and two resilient engaging arms provided respectively on left and right sides of the pressing plate. The engaging arms extend respectively through the through holes and engage releasably the board body.

Abstract: A cover mechanism of covering a hole on a casing is disclosed in the present invention. The cover mechanism includes a base, a first holder, a second holder, a cover and a resilient component. The first holder and the second holder are respectively disposed on the base. The cover is pivotably disposed on the first holder. The resilient component includes a shaft and a curved portion. The shaft pivots to the second holder. A first end of the curved portion is connected to the shaft, and a second end of the curved portion pivots to a connecting hole on the cover. The cover drives the curved portion to generate resilient deformation when rotating from a first position to a second position, and a resilient recovering force of the curved portion can be for stopping the cover at the second position.

Abstract: A housing is usable for positioning selectively a first electronic card having a first locking hole and a second electronic card having a second locking hole, and includes a base plate, a connector for mating with the selected one of the first and second electronic cards, and a movable element including a lever body that has an end portion connected pivotally to the base plate and a third locking hole opposite to the end portion. The lever body is operable to move the third locking hole between a first position, where the third locking hole is aligned with the first locking hole to cooperatively receive a fastener for fastening one of the first and second electronic cards, and a second position, where the third locking hole is aligned with the second locking hole to cooperatively receive the fastener for fastening the other one of the first and second electronic cards.
