　　PCB and IC are both essential components in the field of electronics, but they serve different purposes and have distinct characteristics. Let’s see what are the differences between PCB vs IC. Keep reading!

What is PCB?What is IC?

　　What is PCB?

      PCB (Printed Circuit Board) is an important electronic component, a support for electronic components, and a carrier for electrical connections of electronic components. Because it is made using electronic printing, it is called a “printed” circuit board.

　　The current circuit board mainly consists of lines and patterns, a dielectric layer, holes (Through hole/via), a solder mask, and silkscreen, surface finish and other components.

　　Advantages of PCB1. High density: For decades, the high density of printed circuit boards has been developed with the improvement of integrated circuit integration and the advancement of mounting technology.

　　2. High reliability: Through a series of inspections, tests and aging tests, the PCB can be guaranteed to work reliably for a long time (usage period, generally 20 years).

　　3. Designability: For PCB various performance (electrical, physical, chemical, mechanical, etc.) requirements, printed board design can be realized through design standardization, with short time and high efficiency.

　　4. Productivity: Using modern management, it can carry out standardized, large-scale (quantity), automated and other production to ensure product quality consistency.

　　5. Testability: Relatively complete testing methods, testing standards, various testing equipment and instruments have been established to detect and identify the qualification and service life of PCB products.

　　6. Assemblability: PCB products not only facilitate standardized assembly of various components but also enable automated and large-scale mass production. At the same time, PCB and various component assembly parts can also be assembled to form larger components, systems, and even complete machines.

　　7. Maintainability: Since PCB products and various component assembly components are designed and produced in a standardized manner, these components are also standardized. Therefore, once the system fails, it can be replaced quickly, conveniently and flexibly, and the system can be restored quickly.

　　What is IC?

　　An integrated circuit is a miniature electronic device or component. Using a certain process, the transistors, resistors, capacitors, inductors and other components and wiring required in a circuit are interconnected together, made on a small or several small semiconductor wafers or dielectric substrates, and then packaged in a tube shell, into a microstructure with the required circuit functions. All the components are structurally integrated into a whole, making electronic components a big step forward in miniaturization, low power consumption, intelligence and high reliability. It is represented by the letters “IC” in circuits.

　　Integrated circuits can be divided into three categories: analog integrated circuits, digital integrated circuits and digital/analog hybrid integrated circuits according to their functions and structures.

　　Integrated circuits have the advantages of small size, lightweight, few lead wires and soldering points, long life, high reliability, good performance, etc. At the same time, they are low in cost and convenient for mass production.

　　PCB vs IC – what are the differences?

　　There is a close relationship between integrated circuits and PCBs. The integrated circuit is a whole, welded on the PCB circuit board, and the PCB is the carrier of the integrated circuit. Integrated circuits are the integration of chips, while PCBs are the electrical connections and supports on the circuit board.

　　Understanding of the relationship between the two: the integrated circuit (IC) is welded on the PCB board; the PCB board is the carrier of the integrated circuit (IC). To put it simply, an integrated circuit is a general-purpose circuit integrated into a chip. It is a whole. Once it is damaged internally, the chip will also be damaged. While PCB can weld the components by itself. If the components are damaged, they can be replaced.

What is the difference between the package substrate and PCB

　　The packaging substrate is a kind of electronic substrates that can provide electrical connection, protection, support, heat dissipation, assembly and other functions for chips and electronic components, so as to achieve multi-pin, reduce the volume of packaged products, improve electrical performance and heat dissipation, ultra-high density or multi-chip modularization and high reliability.　　The packaging substrate can be considered as a PCB or thin-thick film circuit substrate with higher performance or special functions. The packaging substrate plays the role of electrical interconnection and transition between the chip and the conventional printed circuit board (mostly motherboard, sub-board, backplane, etc.), and also provides protection, support, heat dissipation, assembly and other functions for the chip.　　With the continuous progress and development of electronic installation technology, the boundaries of various levels of electronic installation are becoming less and less clear. The role of PCB is becoming more and more important. Higher and newer requirements are put forward for PCB and its substrate materials in terms of function and performance.　　Difference between package substrate and PCB　　Printed Circuit Board (PCB) refers to a circuit board that forms a copper circuit pattern on a copper clad laminate according to a predetermined design. Its main function is to connect various electronic components according to a predetermined circuit and act as an electrical connection.　　The packaging substrate and PCB manufacturing principles are similar. It is the extension of PCB to high-end technology to adapt to the rapid development of electronic packaging technology. There is a certain correlation between the two. The packaging substrate is a high-end PCB.　　package substrate　　In electronic packaging engineering, the electronic substrate (PCB) can be used for different levels of electronic packaging (mainly used for the 2nd to 5th levels of the 1st to 3rd level packaging), but the packaging substrate is used for the 2nd and 3rd levels of the 1st and 2nd level packaging, Ordinary PCBs are used for levels 3, 4, and 5 of level 2 and level 3 packages.　　However, they all provide functions such as interconnection, protection, support, heat dissipation, and assembly for electronic components to achieve multi-pin, reduce the volume of packaged products, improve electrical performance and heat dissipation, ultra-high density or multi-chip modularization, and high reliability for the purpose.　　The process and reasons for the separation of the package substrate from the PCB　　After the 1980s, with the wide application of new materials and new equipment, integrated circuit design and manufacturing technology developed rapidly in accordance with “Moore’s Law”, tiny and sensitive semiconductor components came out, large-scale integrated circuits and ultra-large-scale integrated circuits appeared, and high-density multilayer packaging substrates emerged as the times require, which separates integrated circuit packaging substrates from ordinary printed circuit boards. A proprietary manufacturing technology for integrated circuit packaging substrates then formed.　　At present, among the mainstream products of conventional PCB boards, products with a line width/line spacing of 50μm/50μm belong to high-end PCB products. However, this technology still cannot meet the technical requirements of the current mainstream chip packaging. In the field of packaging substrate manufacturing, products with a line width/line spacing of 25μm/25μm have become more common, which reflects that packaging substrate manufacturing is more advanced in technology than conventional PCB manufacturing.　　There are two fundamental reasons for the separation of packaging substrates from conventional printed circuit boards: on the one hand, because the development speed of PCB boards is lower than that of chips, it is difficult to directly connect chips and PCB boards. On the other hand, the cost of the PCB board refinement is much higher than the cost of interconnecting the PCB and the chip through the packaging substrate.　　Main structure and production technology of package substrate　　At present, there is no unified classification standard in the packaging substrate industry. Packaging substrate is usually classified according to the substrate material and manufacturing technology applicable to substrate manufacturing.　　According to different substrate materials, packaging substrates can be divided into inorganic packaging substrates and organic packaging substrates. Inorganic packaging substrates mainly include: ceramic-based packaging substrates and glass-based packaging substrates. Organic packaging substrates mainly include: phenolic packaging substrates, polyester packaging substrates, and epoxy resin packaging substrates.　　Organic Package Substrate　　According to the different manufacturing methods of the packaging substrate, the packaging substrate can be divided into a core packaging substrate and a new coreless packaging substrate.　　Core and coreless packaging substrates　　The core package substrate is mainly divided into two parts in structure, the middle part is the core board, and the upper and lower parts are laminated boards. The production technology of the core packaging substrate is based on the high-density interconnection (HDI) printed circuit board production technology and its improved technology.　　Core and coreless packaging substrates　　A coreless substrate refers to a packaging substrate with a core board removed. The fabrication of the new coreless package substrate mainly produces interlayer conductive structures—copper pillars—by bottom-up electrodeposition technology. It only uses an insulating layer (Build-up Layer) and a copper layer to achieve high-density wiring through a semi-additive (SemiAdditive Process, abbreviated as SAP) build-up process.　　Advantages and disadvantages of coreless packaging substrates　　Advantages　　Thinning;　　The electrical transmission path is reduced, the AC impedance is further reduced, and its signal line effectively avoids the return loss generated by the PTH (copper plated through hole) on the traditional core substrate, which reduces the inductance of the power system loop and improves the transmission. characteristics, especially frequency characteristics;　　The direct transmission of signals can be realized, because all circuit layers can be used as signal layers, which can improve the freedom of wiring, realize high-density wiring, and reduce the limitation of C4 layout;　　Except for some processes, the original production equipment can be used, and the process steps are reduced.　　Disadvantages　　Without core board as support, it is easy to warp and deform in the manufacture of coreless substrates, which is the most common and biggest problem at present;　　Laminate shattering is prone to occur;　　Some new equipment for coreless substrates for semiconductor packaging needs to be introduced. Therefore, the challenges of coreless substrates for semiconductor packaging mainly lie in materials and processes.
