When it comes to high-frequency printed circuit boards, there is a lot you need to know. In this article, you will learn the five main things you should know about high-frequency PCBs, from the way they use energy, to what cherished technology they help to keep functional.
THEY ARE CONSTANTLY TRANSFERING ENERGY
One very important thing to note about high-frequency PCBs is that they are almost constantly transmitting electrical currents. This is because they are always sending and receiving messages.
Think of a printed circuit board, specifically one that is used for high-frequency applications, as similar to the nervous system in the human body. The PCB is similar to the neural pathways in the nervous system. Electrical signals are sent around the PCB to help a desired function occur. This is constantly happening in high-frequency applications, just as it is always happening, even idly, in the human body.
ENGERY MOVES THROUGH THEM QUICKLY AND OFTEN
High-frequency is defined as ?happening often.? This means that a lot of energy is moving through them, usually at a very quick pace. This is to assure that the user of the device the PCB is helping to control can receive and respond to information as quickly as possible.
THEY NEED TO BE DESIGNED WITH HEAT IN MIND
Because high-frequency PCBs are moving a lot of energy very quickly, the printed circuit boards need to be designed with heat in mind. Energy brings along with it a lot of heat. Whenever you?re using a device that seems to be overheating, it is likely caused by some issue within the PCB. This is because it wasn?t designed with heat in mind.
When designing with heat in mind, the manufacturer must consider using a most costly material like Teflon to keep the board from overheating. In addition, they must be sure to attach components in the best places for heat dispersion.
Because most high-frequency PCBs are made of multiple layers, they need to layered correctly. This assures that energy isn?t always going to one specific side or spot on the board.
If a high-frequency PCB isn?t designed with heat in mind, it could experience overheating or burning. This makes it difficult to use the devices it helps to function, making customers increasingly frustrated when their device doesn?t work at its best. Brands want to work with manufacturers who have a good reputation of producing high-quality boards that are designed with these points in mind.
THEY ARE FOUND IN OUR MOST CHERISHED TECHNOLOGY
The advance of technology has resulted in the creation of some of our most cherished technology. So, you probably won?t be surprised to learn that high-frequency PCBs can be found in a number of communications, industrial, and medical devices.
In the communications sector, you can find high-frequency PCBs inside of devices like smartphones and laptops. We are constantly pressing buttons or keys on these devices. In order for that key to function the way we want it to; an electrical signal has to be sent through a high-frequency PCB. That?s why laptops, especially older ones, are more prone to overheating. Another important communications device that uses high-frequency PCBs are GPS systems. GPS systems are constantly sending and receiving information. When they were first designed, they were used just for directions to a known address. Now, GPS systems can locate gas stations, restaurants, and businesses! We rely on them heavily when traveling, and the use of a functioning high-frequency PCB is crucial to keeping us on the right paths.
In the industrial setting, high-frequency PCBs are used in items like power convertors or industrial machines. These are constantly sending signals to maintain power levels and maintain a level of operation. Without the high-frequency PCB, these items wouldn?t function very well.
Lastly, in the medical industry, high-frequency PCBs can be found in devices large and small. For some larger devices, like X-ray and MRI machines, electricity is sent around during a long scanning process in order to identify issues within the body. For smaller devices, like blood sugar monitors, vitals are being taken and reported to an app or separate device to help keep people?s health as balanced as possible.
THEY MUST BE DESIGNED VERY SPECIFICALLY
As you?ve learned, these high-frequency PCBs are found in a number of devices that help provide us with safety and a healthy lifestyle. Because of this, these printed circuit boards have to be designed very particularly, from the size of the board, materials used, spacing of the components, and the calculation of the size of the pathways.
All of this is very important to the functional operation of the printed circuit board. More traditional PCBs can be found in smaller, less expensive items like remote controls. However, these high-frequency boards are found in more expensive equipment that we use for the sake of our health, safety, and as a landline for communication and travel. We do not want this equipment to fair.
For that reason, design software is often used to calculate the perfect width of the pathways on the circuit design. This takes into consideration the length and depth of the pathway as well as the amount of energy traveling down the pathway during different functions. Mathematical equations are heavily relied on, and lasers and special drilling machines are usually used to ensure that guidelines are followed to the very line.
In conclusion, there is a lot to know about high-frequency printed circuit boards. Not only did you learn that they move a ton of energy at high frequencies during each use, but they also have a number of uses in our most loved technology, they should be designed with heat and mind, and their design must be very precise and mathematical.
High-frequency PCBs are usually made with heat resistant materials and are almost always multilayered boards. Their design helps them to stay functioning in harsh environments like extreme cold or heat, so that the devices they help to function can be there for us when we need them most!
