Abstract: A printed circuit board includes a substrate, a trace, first and second ground layers, first and second power vias, and first, second, third and fourth antipads. The trace is routed along a signal layer and the power vias are adjacent to the trace within the substrate. The first and second antipads are around the first power via. The first antipad is located within the first ground layer and the second antipad is located within the second ground layer. The third and fourth antipads are around the second power via. The third antipad is located within the first ground layer and the fourth antipad is located the second ground layer. The first and third antipads are non-shared antipads between the first and second power vias, and the second and fourth antipads are non-shared antipads between the first and second power vias.

Abstract: A printed circuit board, comprising a trace disposed within the printed circuit board, a power via proximate to the trace, and a ground via positioned proximate to the power via such that a return current directionality is orthogonal to the trace.

Abstract: Solid low foaming and low pH all-purpose cleaning and disinfectant compositions are disclosed. The solid disinfectant compositions comprise approximately 50% w/w to approximately 75% w/w of citric acid encapsulated by a binder and approximately 1% to approximately 5.5% w/w of sodium benzoate. The solid cleaning and disinfectant compositions comprise approximately 50% w/w to approximately 75% w/w of citric acid encapsulated by a binder; approximately 1% to approximately 5.5% w/w of sodium benzoate; and approximately 10% w/w to approximately 15% w/w of sodium lauryl sulfate. The solid compositions are dissolved in water to produce a disinfectant solution comprising approximately 1.2% w/v to approximately 2% w/v citric acid and approximately 0.083% w/v to approximately 0.15% w/v sodium benzoate. A 10 minute contact time with the disinfectant solution provides a 5 log10 reduction in Staphylococcus aureus on a surface.
