PCB

Have you ever wondered if a circuit board is an integrated circuit during your electronics studies? Regarding printed circuit boards (PCBs) and integrated circuits (ICs), many people are somewhat confused about these two concepts.2 oz copper thickness in mm In fact, the difference between them is easy to understand. Today, Shenzhen Qinji Electronics will clarify the difference between PCB and IC.

First, let's understand the concept of PCB.

PCB (Printed Circuit Board), also known as Printed Circuit Board or Printed Wiring Board, is an important electronic component, which serves as a support body for electronic components, as well as a carrier for the electrical connection of electronic components. It is called a "printed" circuit board because it is made by electronic printing technology.

Today's circuit boards are made up of wiring and graphics, dielectric layers, holes, solder resist, screen printing, and surface treatment.

Next, let's understand the concept of integrated circuits.

Integrated circuit (integrated circuit) is actually a miniature electronic device or component.plated through hole vs via Through a specific process, a circuit in the required transistors, resistors, capacitors and inductors and other components, as well as wiring interconnections together, the production of a small or several small semiconductor wafers or dielectric substrate, and then encapsulated in a shell, forming a micro structure with the required circuit function. In which all the components in the structure has been composed of a whole, which is an important step in the development of electronic components to the direction of micro-miniaturization, low power consumption, intelligence and high reliability. We usually use "IC" to represent integrated circuits.

According to the different functions and structures, integrated circuits can be divided into analog integrated circuits, digital integrated circuits and mixed digital/analog integrated circuits.

ICs have the advantages of small size, light weight, fewer lead wires and soldering points, long life, high reliability, good performance, low cost, and easy mass production.

So what is the relationship between PCBs and integrated circuits?

Integrated circuits generally refers to the integration of chips, such as the north bridge chip on the motherboard, CPU internal are known as integrated circuits, initially known as integrated blocks. PCB, on the other hand, refers to the circuit boards we usually see and the process of printing and soldering chips on them.

Simply put, an integrated circuit is a general-purpose circuit integrated into a single chip to form a whole. Once there is damage inside it, the whole chip will fail. But! PCB is able to weld its own components, and if it is broken, you can also replace the components, which is very convenient. We can remember this way: integrated circuits (ICs) are soldered on PCB circuit boards; and PCB boards are the carrier of integrated circuits (ICs).
