Abstract: An integrated circuit package including electrically floating metal lines and a method of forming are provided. The integrated circuit package may include integrated circuit dies, an encapsulant around the integrated circuit dies, a redistribution structure on the encapsulant, a first electrically floating metal line disposed on the redistribution structure, a first electrical component connected to the redistribution structure, and an underfill between the first electrical component and the redistribution structure. A first opening in the underfill may expose a top surface of the first electrically floating metal line.

Abstract: A semiconductor structure includes a functional die, a dummy die, a redistribution structure, a seal ring and an alignment mark. The dummy die is electrically isolated from the functional die. The redistribution structure is disposed over and electrically connected to the functional die. The seal ring is disposed over the dummy die. The alignment mark is between the seal ring and the redistribution structure, wherein the alignment mark is electrically isolated from the dummy die, the redistribution structure and the seal ring. The insulating layer encapsulates the functional die and the dummy die.

Abstract: A mechanism, configured for positioning a work piece, includes a support member and a position assembly. The position assembly includes a guiding member and a positioning sleeve sleeved on the guiding member. The guiding member detachably is coupled to the support member. The positioning sleeve is detachably coupled to the support member. The guiding member is partially exposed from the positioning sleeve.

Abstract: A positioning device includes a fixing mechanism, a first positioning assembly, a second positioning assembly. The fixing mechanism includes a base, a first moving member movably passing through the base, and a second moving member movably passing through the base. The first positioning assembly includes a bottom board and two first guide portions protruding from the bottom board. Each first guide portion forms one first incline surface. The second positioning assembly includes a base body and two second guide portions. The base body is positioned between the two first guide portions respectively positioned on opposite side surfaces of the base body. Each second guide portion forms a guiding surface. The first moving member is fixed with the bottom board at one end away from the base. The second moving member is fixed with the base body at one end away from the base.

Abstract: A laser detection device includes a mounting member, a laser displacement sensor fixed on the mounting member, and a reflective member. The laser displacement sensor includes a laser transmitting head configured to emit laser beams to a workpiece along a first line of direction, and a laser receiving head coupled to the laser transmitting head and configured to receive the laser beams reflected from the workpiece. The reflective member includes a prism fixed on the mounting member, and spaced away from the laser displacement sensor. The prism has a reflective surface on an incline with the first line of direction and configured to reflect a part of the laser beams via the reflective surface to the workpiece along a second line of direction different from the first direction. The part of the laser beams are directly reflected or reflected via the prism to the laser receiving head.

Abstract: A screen protecting assembly includes a pivot shaft, a curtain, two connecting bases and two rotating buttons. The curtain wraps around the pivot shaft. The connecting bases are connected to two opposite ends of the pivot shaft. Each rotating button has a first connecting portion and a second connecting portion. The first connecting portion engages the pivot shaft, and the second connecting portion is rotatably connected to the connecting base. When the rotating buttons are rotated in a first direction, the curtain unfolds to cover a screen of the electronic device. When the rotating buttons are rotated in a second direction counter the first direction, the curtain wraps around the pivot shaft again, so that the screen of the electronic device is exposed.
