The Northbridge chip generally works according to the type and frequency of the CPU, as well as the type and maximum capacity of the memory, and provides a high-speed interface to external bus devices such as PCI/AGP. The northbridge is usually located on the motherboard near the CPU socket, and because this type of chip generally generates more heat, it is usually equipped with a heatsink on this chip.
General LED packaging plant, 5 feet for the three chips positive, 6 feet for the three chips negative. Triangle notch for MARK point, RGB beads triangle side for the positive pole. Monochrome light or white light seal triangle side is generally defined as the negative pole, this is not absolute, to see the supplier acknowledgement shall prevail.
The number and type of computer pins vary, but the basic principles of computers always remain the same. In the future, as technology develops, we can look forward to the emergence of more and more advanced pins and interfaces, which will drive computer technology forward.
The foot is the GATE terminal, the 3-pin is the CS terminal, the 4-pin is the INV terminal, the 5-pin is the COMP terminal, and the 6-pin is the VDD terminal. Using this chip plus a switching power supply pulse transformer is very easy to form a switching power supply. Chip above the printed word is generally not the model, only to the physical circuit against the typical common 6-pin power supply chip.
At this point, press the power switch to start the computer, in the moment of pressing the power switch, the power switch to the NQ chip or I/O chip to send a boot trigger signal, triggering the boot circuit work, at this time, the power interface of the 14th pin becomes low, the ATX power supply began to work.
A computer chip is actually an electronic part There are millions of resistors, capacitors, and other small components in a computer chip.
The COMS chip on a computer's motherboard is near the CMOS battery, and in the picture, the CMOS chip on the motherboard is labelled with a green post-it note next to the push-button battery.The CMOS chip belongs to the ram-ram-ram, and the push-button battery is mainly responsible for powering up the CMOS, and in the event of a power outage, the BIOS settings will be lost, for example, every time you turn on the computer, the system time will not be correct.
The main chip in the computer motherboard is generally referred to as the "CPU" Central Processing Unit CPU on the computer motherboard CPU back contacts Central Processing Unit (CPU, central processing unit) as the core of the computer system's computing and control, is the information processing, the operation of the programme of the final execution unit. The CPU is the final execution unit.
Inside the computer CPU is actually a semiconductor design layout. Including digital circuit layout, analogue circuit layout, RAM/CACHE part of the version, as well as power and IO layout. There are also protection circuits and so on. Each part is coloured differently depending on the design specifications of the layout, and it looks very intuitive.
1, the raw material construction is different, different composition. According to the query computer network shows that the wafer is the main raw material for LED, can be free to light, the chip is a solid-state semiconductor device, is a PN junction, can be directly converted to light.
2, chip and wafer difference: integrated circuits, or microcircuits, microchips, chips (in electronics is a way to miniaturise circuits (mainly including semiconductor devices, but also passive components, etc.), and is usually manufactured on the surface of semiconductor wafers.
3, led wafer is the main raw material for LED, LED mainly rely on the wafer to emit light. led chip is a solid state semiconductor device, that is, a P-N junction, which can directly convert electricity into light.
4, light-emitting diode) chip is a solid-state semiconductor device, it can be directly converted into light. the heart of the LED is a semiconductor wafer, the wafer is attached to one end of a bracket, one end of the negative terminal, the other end of the power supply is connected to the positive electrode, so that the entire wafer is encapsulated by epoxy resin.
