The relationship between pcb and integrated circuit


The integrated circuit is soldered on the PCB board. The board is the carrier of the integrated circuit.
Many people have heard of the abbreviation "PCB". But what does it mean? It's actually very simple, it's a printed circuit board (PCB). It will appear in almost every electronic device. If there are electronic parts in a certain device, they are all mounted on PCBs of different sizes. In addition to fixing various small parts, the main function of the PCB is to provide electrical connections between the upper parts. As electronic equipment becomes more and more complex, more and more parts are needed, and the circuits and parts on the PCB are becoming more and more dense. The bare board (no parts on it) is also often referred to as "Printed Wiring Board (PWB)". The base plate of the board itself is made of materials that are insulated and heat-insulated, and not easy to bend. The tiny material that can be seen on the surface is copper foil. The copper foil was originally covered on the entire board, but the middle part was etched away, and the remaining part became a network of small lines. These lines are called conductor patterns or wiring, and are used to provide circuit connections for parts on the PCB. Usually the color of PCB is green or brown, which is the color of solder mask. It is an insulating protective layer that can protect the copper wire and prevent parts from being welded to the wrong place. A silk screen is also printed on the solder mask. Usually words and symbols (mostly white) are printed on this to mark the position of each part on the board. The screen printing circuit board surface is also called the legend surface.

         An integrated circuit is a miniature electronic device or component. A certain process is used to interconnect the transistors, diodes, resistors, capacitors and inductors and other components and wiring required in a circuit, fabricate them on a small or several small semiconductor wafers or dielectric substrates, and then package them in a Inside the shell, it becomes a miniature structure with the required circuit functions; all of the components have been structured as a whole, so that the volume of the entire circuit is greatly reduced, and the number of lead wires and soldering points is also greatly reduced, thereby making the electronics Components have taken a big step towards miniaturization, low power consumption and high reliability.
         Integrated circuits have the advantages of small size, light weight, few lead wires and soldering points, long life, high reliability, and good performance. At the same time, they have low cost and are convenient for mass production. It is not only widely used in industrial and civilian electronic equipment such as tape recorders, televisions, computers, etc., but also in military, communications, and remote control. The use of integrated circuits to assemble electronic equipment can increase the assembly density by tens to thousands of times compared with transistors, and the stable working time of the equipment can also be greatly improved.
       It is represented by the letter "IC" in the circuit (also use the text symbol "N", etc.).
        PCI is the circuit board on which various components are defended! IC is an integrated circuit, a member that integrates many components, and it is also soldered on the PCB board, which is the flat component with the largest area!
How do you say their relationship? It is the relationship between the car and the highway or the relationship between the computer and the wire.

The motherboard of your computer is PCB and cpu is IC~
