Printed circuit boards (PCBs) are boards consisting of conductive tracks, pads and other features that are laminated onto a thin sheet of copper foil, or printed on a surface coated with copper. These sheets are used as a base for electronic components, such as resistors, capacitors and transistors. Commonly-used abbreviations include PCB and PCBA (printed circuit board assembly).

Uses of Printed Circuit Board (PCBs):
Printed circuit boards, or PCBs, are used in many consumer electronics applications. They are found in virtually every kind of device that can be plugged into a wall socket, as well as industrial applications and automotive equipment. The main advantage of using printed circuit boards is their ability to combine several components into one assembly. This reduces both cost and weight when compared to using individual discrete electronic components.

Manufacturing Process
PCBs are made from a variety of different materials, depending on what their function will be. Almost all PCBs have an insulating base made of either epoxy-bonded paper or glass cloth. The majority of PCBs have a top layer that can be copper, but other materials may be used. PCBs can also have additional layers such as an aluminum sheathing that protects copper traces and pads from damage during assembly processes like wave soldering or reflow soldering.

Additional components can be added to PCBs to add functionality such as heat sinks to prevent overheating. A few types of electrical components are attached directly to printed circuit boards; most require some form of surface mount technology (SMT). In some cases, these components may actually replace parts of a circuit board entirely when designers want to minimize size and weight in devices like cell phones or laptops. When finished, boards go through various testing phases before they’re sent out for sale.
Market Demand of Printed Circuit Board (PCBs)
The potential growth difference for the PCB sector between 2020 and 2025 is USD 12.86 billion. Market momentum is predicted to accelerate at a CAGR of 3.60 percent over the forecast period. The increased use of cellphones is one of the primary drivers driving the PCB sector. Smartphone usage is expected to accelerate globally due to the availability of low-cost smartphones and expanding global Internet penetration.
