Circuit Board (English: Printed Circuit Board, also known as: printed circuit board, PCB) is one of the indispensable parts of electronic equipment, its main function is to miniaturize the circuit, intuitive, for the mass production of fixed circuits and optimize the layout of electrical appliances plays an important role.

YPK117A-61163280 The YPK117A-61163280 circuit board mainly consists of welding pad, through hole, mounting hole, wire, component, connector, filler, and electrical boundary. The main functions of each component are as follows: 1.

Pad: Metal hole for welding the pin of a component.

Through holes: There are metal through holes and non-metal through holes, where the metal through holes are used to connect the component pins between the layers.

Mounting hole: Secure the circuit board.

Wire: YPK117A-61163280 Electrical network copper film connecting component pins.

Connector: The component that connects the circuit board.

Filling: Copper coating of YPK117A-61163280 ground network can effectively reduce the impedance.

Electrical boundary: Determine the size of the board, and all components on the board can not exceed the boundary.
