Printed Circuit Boards (PCBs): What They Are Made Of and How They Work

Printed circuit boards, or PCBs, are an essential component of modern electronics. They are used in everything from smartphones to spacecraft, and have revolutionized the way we design and build electronic devices. But what are PCBs made of, and how do they work? In this article, we'll take a closer look at these fascinating devices and explore the role our company plays in the industry.

What Are Printed Circuit Boards?

Before we dive into the materials that PCBs are made of, let's first review what PCBs actually are. In simple terms, a PCB is a board made of non-conductive material (usually fiberglass or plastic) that contains a pattern of conductive pathways etched onto its surface. These pathways, or traces, are used to connect the various electronic components that are mounted onto the board, allowing them to communicate with each other and perform their intended functions.

What Are PCBs Made Of?

The non-conductive material used to make a PCB is typically called the substrate. Substrates can be made of a variety of materials, but the most common ones are fiberglass and plastic. Fiberglass is the more traditional choice, and is still widely used in many applications. It is made by weaving together glass fibers and then impregnating them with a resin. This creates a strong, rigid material that is resistant to heat and chemicals.

Plastic substrates, on the other hand, are a more recent development. They are made of various types of plastic, such as polyimide or polyester, that have been reinforced with glass fibers. Plastic substrates are more flexible and lightweight than fiberglass, making them ideal for applications where space and weight are at a premium.

Regardless of the substrate material, the conductive pathways on a PCB are typically made of copper. Copper is an excellent conductor of electricity, and is also easy to etch onto the surface of the substrate using a chemical process. Once the copper has been etched into the desired pattern, a layer of solder mask is applied to protect the copper traces and provide a surface for soldering electronic components onto the board.

How Do PCBs Work?

As we mentioned earlier, the conductive pathways on a PCB are used to connect the various electronic components that are mounted onto the board. These components can include resistors, capacitors, transistors, and many others, and are typically soldered onto the board using a wave soldering or reflow process.

Once the components are mounted, the board is ready to be used. When power is applied to the board, electricity flows through the copper traces, connecting the various components and allowing them to communicate with each other. By carefully designing the pattern of copper traces on the board, engineers can control the flow of electricity and ensure that the device functions as intended.
