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: An electromagnetic relay capable of externally and manually controlling, turning on, and shutting off electric power includes casing, push-pull rod and relay module. The casing has top cover, where slideway is formed, and an end of the slideway has bump. The push-pull rod is installed to the slideway and has an end formed into hook portion and passed into the casing. An open slot, which has fitting hole and sliding hole, is formed on the push-pull rod. The relay module is installed at the chassis and has elastic contact plate assembly and lever, and an end of the lever is engaged with the hook portion. After the fitting hole is sheathed on the bump, the sliding hole is moved relative to the bump, so that the hook portion drives the lever to push the elastic contact plate assembly to define electrical connection or disconnection state according to different requirements.

Abstract: An electromagnetic relay includes a casing, a coil set, a rotating bridge, first and second extension arm, first and second switch conductive plate assemblies, and first and second gripper modules. The novel design of the rotating bridge allows the first and second switch conductive plate assemblies to have synchronous contact or disconnection and provide sufficient and appropriate force to a first movable contact and a first fixed contact of the first switch conductive plate assembly and a second movable contact and a second fixed contact of the second switch conductive plate assembly to achieve a stable conduction and ensure a reliable separation for a disconnection, so as to achieve the effects of reducing the excessive change of resistance during operation, preventing high temperature caused by incomplete contacts, and improve application performance.
