What is the material of the computer mainboard PCB?
On the circuit board, there is a patchwork of circuit wiring; and then the above is the edges and corners of each component: slot, chip, resistors, capacitors and so on. When the host is powered on, the current will pass through the CPU, the north and South Bridge chip, memory slot, AGP slot, PCI slot, IDE interface, and the serial port, parallel port and PS/2 interface of the main board edge. Subsequently, the motherboard will identify the hardware according to the BIOS (basic input and output system), and enter the operating system to play the function of supporting the system platform.
The six panel adds the auxiliary power layer and the signal layer. The six layer PCB board has stronger electromagnetic interference resistance, and the mainboard is more stable.
The flat surface of the motherboard is a PCB printed circuit board which is divided into four layers and six boards. Four layers: main signal layer, ground layer, power layer and sub signal layer.
