What is the function of chip circuit board?
Pcba Prototypes and PCB are becoming more and more important in today's electronic products, which is equivalent to the lifeblood of electronic products. It is one of the indispensable and important originals; we all know that the circuit board can really promote the normal operation of Electronic Components is its circuit Connect various electronic components, because the electronic components are connected to make the circuit board play a normal role, then what is their role, today we will introduce the role of the originality electronics IC.
We all know that the originality electronics IC is the core element in the circuit board, and its position is beyond the originality electronics IC to determine whether a circuit board is good or bad; the circuit board can be divided into the north bridge chip and the south bridge chip according to the position of the circuit. The two correspond to different positions and functions; the north bridge chip generally provides support for the type and main frequency of the CPU, the type and maximum capacity of the memory, ISA/PCI/AGP slot, ECC error correction, etc., and it is usually close to the CPU on the motherboard The position of the socket, because the heat of this kind of chip is generally high, so there is a heat sink on this chip. The South Bridge chip is mainly used to connect to Cable Connectors I/O Connectors and ISA devices, and is responsible for managing interrupts and DMA channels to make the device work more smoothly. It provides control of KBC (keyboard controller) and RTC (real-time clock). Support for USB (Universal Serial Bus), Ultra DMA/33 (66) EIDE data transfer mode and ACPI (Advanced Energy Management), etc., near the PCI slot.
