Commonly Use Circuit Boards

The printed circuit board, or PCB, is the backbone of many electronic devices we use on a daily basis. It is a flat sandwich of insulating material and copper-plated metal that has a pattern of conducting traces, pads for connections and features like solid conductive areas etched from its surface. The insulated material helps protect the copper from corrosion and prevent unwanted electrical contact between the conductive metal and stray bare wires. Using a computer-aided design (CAD) software, designers create a schematic of the board’s layout. Once the design database is configured and network connectivity information imported from the schematic, it’s time to place components on the PCB. Each component’s footprint has a net connection displayed as a ghost-line image on the PCB outline, and a skilled designer knows how to place them in the most efficient way possible while minimizing signal interference between circuit traces and reducing the amount of solder required for the connections.

Almost all industries have some level of need for the technology that PCBs circuit board provide. For example, in the industrial sector, PCBs are used to power much of the equipment found in manufacturing and distribution centers. Similarly, the medical industry relies on electronics to help keep us healthy and alive. For example, electronic blood pressure and glucose monitors, infusion pumps, pacemakers and more rely on small PCBs to function properly.

In the automotive and aerospace industries, there are particular requirements that need to be met. These industries often require flexible PCBs, which can be made to conform to the space limitations of a specific device. This flexibility also allows the PCB to withstand vibrations and other physical shocks that may occur in these environments.

What Industries Commonly Use Circuit Boards?

There are many different types of PCBs, with some having multiple layers and others having fewer. Single-layer PCBs have the copper layer applied to one side of the insulating material, and this type is the most common. It’s used in home computers, calculators, cameras, radio and stereo equipment, printers and more.

The most complex PCBs are multilayered and can have as few as four or as many as 12 layers of copper. These are often used in file servers, data storage and weather forecasting equipment. Rigid PCBs are also commonly used in computer motherboards, and these are usually rigid and made of materials that can withstand high levels of vibration, heat and other environmental factors.

There are also special-purpose PCBs for surface-mount components, which have a finer lead pitch than other PCBs and are easier to solder by hand. These are known as breakout boards and have the leads from each component broken out to separate terminals on the PCB, making them easy for manual connections to be made. These are often used in prototypes and for testing purposes. Another method of connecting components to a PCB is by using the machine-routed technique, which uses a patented system of interconnecting insulated wires embedded in a non-conducting matrix. This was popular in the 1980s and 1990s but has since been replaced by more modern techniques.
