Board Plane

- Mar 04, 2017 -

Board plane is a PCB (printed circuit board), generally use four layer boards or six boards. In contrast, in order to save costs, low quality boards for four-layer Board: main signal, grounding, power, signal, and six boards increased the auxiliary power supply and signal layers and, therefore, six-layer PCB Board anti-electromagnetic interference ability is stronger, the motherboard may also be more stable.

Working principle

In the circuit board below, 4-storey glass circuit wiring; above, or parts of a clear division of Labor: slots, chips, resistors, capacitors, etc. When the host is powered on, the current in an instant by CPU, North Bridge chip and memory slots, and AGP slots, PCI slots, IDE interface, and the edge of the System Board's serial port, parallel port, PS/2 interface and so on. Subsequently, the Board based on the BIOS (basic input/output system) to identify the hardware and develop support systems platform function into the operating system.
