The included angle between the at least one of the second metal lines and the two adjacent first metal lines is greater than or equal to 0 degrees and less than or equal to 10 degrees. The first width of one of the two adjacent first metal lines is greater than the second width of the at least one of the second metal lines.

Abstract: An electronic device is provided. The electronic device includes a redistribution structure, an electronic unit and a first conductive pad. The first conductive pad is disposed between the redistribution structure and the electronic unit. The electronic unit is electrically connected to the redistribution structure through the first conductive pad. The first conductive pad has a first coefficient of thermal expansion and a first Young's modulus. The first coefficient of thermal expansion and the first Young's modulus conform to the following formula: 0.7×(0.0069E2?1.1498E+59.661)?CTE?1.3×(0.0069E2?1.1498E+59.661), wherein CTE is the first coefficient of thermal expansion, and E is the first Young's modulus in the formula.

Abstract: A semiconductor device includes a first region and a second region, and the second region surrounds the first region. The semiconductor device includes at least one electronic unit, a redistribution structure, a plurality of first pads, and a plurality of second pads. The redistribution structure may be electrically connected to at least one electronic unit. A plurality of first pads are arranged on the redistribution structure and correspondingly to the first region. There is a first pitch between two adjacent first pads. A plurality of second pads are arranged on the redistribution structure and correspondingly to the second region. There is a second pitch between two adjacent second pads, so that the first pitch is smaller than the second pitch.

Abstract: A gas regulator has a base and a blocking mechanism. The base has a transporting passage. The blocking mechanism has a plug, a first elastic unit, an elastic sealing sheet, and a switching unit. The plug is moveably mounted in the transporting passage and forms a gap for gas to pass through the transporting passage. The first elastic unit moves the plug to block an end opening of the transporting passage. The blocking chamber is formed between the elastic sealing sheet and the base. The switching unit is connected to the elastic sealing sheet and moves along with the deformation of the elastic sealing sheet relative to the plug. The switching unit abuts the plug to space the plug apart from the end opening. When the gas pressure is too high, the switching unit moves to allow the plug to move to block the end opening.

Abstract: A gas regulator with a gas-amount display assembly is capable of showing an amount of gas in a gas storage device connected to the gas regulator, and the gas regulator includes a regulating assembly, a detecting assembly, and a display assembly. The detecting assembly has a touch switch and an abutting component selectively abutting the touch switch. The display assembly and the detecting assembly are separated from each other. The display assembly changes its display state according to whether the abutting component abuts the touch switch or not. With the detecting assembly and display assembly separated from each other, the regulating assembly and the detecting assembly can be disposed with the gas storage device at a safe position, and the display assembly may be disposed at a position that can be observed easily. Thus, the user can check the amount of the gas at any time.

Abstract: A lid of gas pressure regulator has a top segment, a surrounding wall, a pressing segment, and a gap. The surrounding wall protrudes downward and annularly from an annular edge of the top segment. The pressing segment protrudes transversely, outward and annularly from a bottom edge of the surrounding wall, and extends upward. The gap is formed between the surrounding wall and the pressing segment. Because the pressing segment is thinned and the gap is formed between the pressing segment and the surrounding wall, the overall volume and the weight can be reduced, and the pressing segment has sufficient height to prevent an opening edge of the seat from being bent at a large angle and fracture.
