Abstract:
An apparatus for cleaning at least one object may include a cleaning chamber, an air-blowing unit, a rotating unit and a collecting unit. The at least one object may be received within the cleaning chamber. The air-blowing unit may be configured to blow air to the at least one object in the cleaning chamber to float particles from the at least one object. The rotating unit may be configured to rotate the at least one object to provide the at least one object with the air in at least two directions from the air-blowing unit. The collecting unit may be configured to collect the floated particles.
Abstract:
An apparatus for holding stacked trays includes a cover and a hooking unit. The cover protects an upper surface of the stacked trays. The hooking unit is connected to the cover. The hooking unit is drawn from at least two side surfaces of the cover along the side surfaces of the stacked trays, to hold both lower ends of the stacked trays. Thus, the stacked trays may be easily held only by hooking the hook on the lower end of the stacked trays.
Abstract:
A locking apparatus for locking a magazine configured to receive a printed circuit board (PCB) may include an actuator, a rotating block, and a locking member. The actuator may be installed on the magazine. The rotating block may be connected to the actuator. The rotating block may be rotated about a vertical axis. The locking member may be rotatably connected to the magazine about the vertical axis. The locking member may be selectively combined with the rotating block to block a front face of the magazine, thereby preventing breakaway of the PCB from the magazine.

Abstract:
A burn-in board connection device includes a first connection unit to hold a burn-in board and move in a first direction perpendicular to the burn-in board that is inserted in a chamber of a burn-in test device, a second connection unit to move in a second direction parallel to the burn-in board to attach/detach the burn-in board that is held by the first connection unit to/from a connector disposed in the chamber. A burn-in board connection method includes coupling a finger to the burn-in board by moving the finger in a first direction, attaching the burn-in board to a connector by moving the finger in a second direction, and driving the finger by converting a rotation of a servo motor into a linear movement of the finger.
Abstract:
Provided is an apparatus for clamping a stack of trays that allows automation and prevents distribution of particles or foreign materials during a semiconductor fabrication process. In one embodiment, the apparatus includes a frame body surrounding the stack of trays, a plurality of belt drums, and a hook. Each belt drum is attached to one side of the frame body has a belt and spiral spring. The belt is structured to securely surround the stack of trays using the elastic tension of the spiral spring member mounted in the belt drum. The hook is structured to be rotatably connected to the frame body and slid under a bottom surface of the stack of trays to secure the stack of trays.

Abstract:
A system for facilitating the handling and transporting of semiconductor packages includes a stock of trays in which semiconductor packages can be held, and a tray carrier by which a stack of the trays can be easily handled using automated equipment and without producing dust. The tray carrier includes a frame having an open bottom end through which a stack of trays can be inserted into the frame, belt drums mounted on both sides of the bottom end of the frame, fork blocks mounted to the frame under the belt drums, and a belt extending from the belt drums through the fork blocks and across the open bottom end of the frame. When the tray carrier is placed over a stack of the trays, the belt surrounds the top and sides of the stack of trays. The fork blocks include prongs that are movable into the space constituting the open bottom end of the frame so as to support the bottom of the stack of trays. The tray carrier also has fork handles for actuating the fork blocks, and locking handles for locking the fork blocks in place.
