Abstract: A working system for a semiconductor packaging process includes a machine equipment, a supply unit and a return device. The supply unit is correspondingly connected to the machine equipment and includes an input device and an output device. The return device is connected to the input device and the output device. As such, a magazine is transferred from the input device to the output device via the return device, thereby accelerating the operation speed of a production line.

Abstract: A working system for a semiconductor packaging process includes a machine equipment and a supply unit correspondingly connected to the machine equipment, and the supply unit includes an input device, an output device and a pick-and-place device for inputting a magazine to the input device and/or outputting the magazine from the output device, so that the magazine is automatically transported to the input device or away from the output device by the pick-and-place device, thereby accelerating the operation speed of the production line.

Abstract: A multi-functional leg stretching apparatus comprises an anchoring device made up of a positioning seat and a retaining block for the winding around of an elastic strap there-through, a fixed inner tube securely mounted at the anchoring device therein with both ends thereof symmetrically protruding outwards at both sides of the anchoring device, and a pair of movable outer tubes that, each having a pedal, and plate-like protective frame with an embedded support plate mounted thereto, are symmetrically joined to both ends of the fixed inner tube thereof. A resilient member is accommodated inside the fixed inner tube to extend outwards at both ends into which an abutting element is respectively adapted to abut against the adjacent outer edge of the movable outer tube thereby, permitting the abutting elements affected by the bounding force of the resilient member to flexibly draw and limit both movable outer tubes gathering towards the positioning seat of the anchoring device thereby.
