Abstract: A copper foil structure and a manufacturing method thereof are provided. In some embodiments, the copper foil structure includes a copper foil layer and a conductive organic anti-oxidation layer. The conductive organic anti-oxidation layer is disposed on the copper foil layer, and the conductive organic anti-oxidation layer includes an organic antioxidant and a conductive polymer.

Abstract: The disclosure provides an electronic device and a manufacturing method thereof. The electronic device includes a package structure, a circuit structure, a bonding structure and an external element. The circuit structure is disposed on the package structure and is electrically connected to the package structure. The circuit structure has a recess. The bonding structure includes a first bonding pad and a second bonding pad. The second bonding pad is disposed in the recess, and the second bonding pad is disposed on the first bonding pad. The bonding structure is disposed between the circuit structure and the external element. The external element is electrically connected to the circuit structure through the bonding structure. A width of the first bonding pad is smaller than a width of the second bonding pad.

Abstract: A circuit board cleaning system includes a cleaning tank, an ion exchange resin column, and a pump unit. The cleaning tank accommodates a cleaning liquid and allows a circuit board to be immersed in the cleaning liquid. The cleaning liquid includes a liquid water and a hydrocarbon-based surfactant. An ion exchange resin filled in the ion exchange resin column is a basic ion exchange resin. The pump unit is configured to pump the cleaning liquid into the ion exchange resin column, and enable the cleaning liquid to pass through the ion exchange resin column. When the cleaning liquid passes through the ion exchange resin column, the basic ion exchange resin deprotonates the hydrocarbon-based surfactant. After the cleaning liquid passes through the ion exchange resin column, the cleaning liquid is returned to the cleaning tank to remove acidic residue remaining on a surface of the circuit board.

Abstract: A cartridge structure for a water filter contains a body, an upper cover connected with the body, and a lower cover coupled with the body. The body includes plural filtering layers defined therein, the upper cover includes an inlet defined on a top end thereof and a first groove formed around an inner side thereof, and the lower cover includes an outlet defined on a bottom end thereof and a second groove formed around an inner side thereof, such that plurality of filtering materials are fixed in the first groove and the second groove. Thereby, water flows into the inlet and then is filtered by the filtering materials and the filtering layers so as to enhance filtering effect. Also, after a period of using time, the upper cover and the lower cover are removed from the body so as to take the filtering layers, thus recycling the filtering layers.

Abstract: A food heating device contain: a cup and a base used to hold the cup and including a transmission mechanism. The cup includes plural ribs mounted around an inner wall thereof, and each rib extends downwardly along the inner wall of the cup. The cup also includes plural protrusions fixed on a bottom end thereof and a shaft secured at a central position of the bottom end thereof. The shaft has a blade disposed on a top end thereof, such that the shaft is inserted through the bottom end of the cup and is connected with a transmission mechanism via a bearing. Thereby, ingredients are crushed into juices after the transmission mechanism drives the blade, and during a crushing process, the shaft nibs with the bearing to produce a high temperature, and the ingredients are crashed in the cup by the plural ribs and the protrusions to be heated quickly.

Abstract: A dewatering device of a vegetable and fruit processor is combined with a main machine that drives and rotates a filter trough and a filter to separate residues from vegetable and fruit juices.

Abstract: A fruit/vegetable juice spinning filter includes a container, a strainer basket, and a cover. The container internally defines a chamber and is provided with a bottom opening and a juice outlet. The strainer basket is disposed in the chamber of the container to define a filtered juice receiving space between the container and the strainer basket. The strainer basket has a spinning shaft downward extended through the bottom opening of the container to associate with an external rotary drive source. The cover closes a top of the container and the strainer basket. When an amount of primarily extracted and pulp-containing fruit/vegetable juice is poured into the strainer basket, and the spinning shaft and accordingly the strainer basket are driven by the external rotary drive source to spin, the primarily extracted juice in the strainer basket is centrifugally separated from the pulp to produce almost pulp-free juice.

Abstract: A lighting equipment for an eyeglasses includes a fin attached to one side of a main frame of the eyeglasses. A clamping frame has a pair of retaining plates formed at one side and a pair of clamping plates formed at an other side. The fin is force-fitted within the retaining plates of the clamping frame. A housing has an open lateral end enclosable by the clamping frame. A bulb is force-fitted and laterally rotatable within the housing. The light beam emitted from the bulb is adjustable both in a vertical direction and in a lateral direction.
