Abstract

The invention provides an array resistor and a PCB board applied with the array resistor. The array resistor comprises a packaging body and resistors in pairs arranged in the packaging body. Resistors in each pair are symmetrically crossed and insulating with each other; two ends of each resistor are respectively provided with corresponding pins on the packaging body; and two ends of each resistor are electrically connected to packaging body pins respectively. The invention can realize crossing output transformation of signals, solve difficulty wiring and adjusting, and guarantee signal quality; meanwhile, crossing output transformation of differential signals is realize through the array resistor, so as to solve difficulty in wiring and adjusting and realize a function like a twisted pair on a board, and the array resistor is tighter than the twisted pair, has controllable spacing and amazing effect on interference inhibition.

Description

technical field [0001] The invention relates to a resistance exclusion and a PCB board using the resistance exclusion. Background technique [0002] The signal rate on the existing PCB board is getting faster and faster, the wiring density is getting higher and higher, and there are more requirements for PCB routing. The use of resistance exclusion can save space for PCB wiring, especially for high-density PCBs. Resistance exclusion is several resistors packaged together. It is more convenient to use resistance exclusion than to use several resistors, so resistance exclusion applications have been developed rapidly. The existing exclusions are all straight-through. When the differential signal crosses and the routing needs to be changed, the existing exclusions are not applicable. It is necessary to adjust the wiring or change the position through PCB punching and threading. However, wiring adjustment is very difficult for high-density PCBs, and changing positions through P...
