Printed circuit boards (PCBs), also called printed wiring cards, are the key elements in modern electronic devices like TVs, laptops, microwaves, and even car sensors. These boards connect various electronic components in gadgets, helping them function. PCBs are made using layers of different materials, such as substrate (FR4), copper, solder mask, and silkscreen, which are laminated together. This article explores the different types of circuit boards, their components, and the leading PCB manufacturers.

Types of PCBs
Circuit boards can be categorized depending on their manufacturing process, design, and application. The most popular types of circuit boards are:

Rigid PCBs
These are the most commonly used circuit boards due to their strength and durability. Rigid PCBs are made of a hard base material like fiberglass, and their components are attached to the surface using soldering techniques.

Flexible PCBs
A malleable substrate material, like polyimide, is used to manufacture flexible PCBs. These boards can be bent and folded to fit into tiny spaces. As a result, they are suitable for usage in wearable electronics and devices with limited room.

Rigid-flex PCBs
Rigid-flex PCBs combine the benefits of rigid and flexible PCBs. They are manufactured by combining stiff and pliable substrates into a single board. Rigid-flex PCBs are incredibly reliable, making them suitable for sophisticated electrical devices like digital cameras.

PCB components
The common components one would find on a circuit board are:

Integrated circuits
Integrated circuits, popularly called ICs, are the most vital parts of a PCB. They consist of many transistors, resistors, and capacitors attached to a single chip. ICs are utilized in virtually every electronic device, from mobile phones to large-scale manufacturing equipment.

Connectors
The various circuit board components are linked together via connectors. Connectors are utilized frequently in computer systems as well as consumer electronics. They can be found in various forms and dimensions, such as USB, HDMI, and D-sub connectors.

Switches
Electronic circuits can be turned on and off using switches. Switches can also be used to select between different PCB functionalities. Most consumer electronics and industrial machinery use switches. They come in different forms, such as slide, toggle, rotary, and pushbutton.

LEDs
Light-emitting diodes (LEDs) are used in electronic devices to convey specific information, such as whether the device is on or off. LEDs come in different colors and sizes and are often used in displays, status indicators, and backlights.

Transformers
Transformers are used to change an electrical circuit’s voltage or current. They often perform the function of converting AC voltage into DC voltage in power supplies and audio equipment.
