Aplicação de PCB FlexívelPostado em 10/07/2020
Como o nome sugere, o PCB flexível possui flexibilidade física. Essas PCBs são amplamente utilizadas em dispositivos mecanicamente sensíveis porque a flexibilidade permite que a placa de circuito resista à vibração. O PCB flexível é mais durável do que as placas de circuito tradicionais, mas o fabricação de PCBé sensível e complicado.
Due to the light weight of the design, the circuit board can be shaped according to the housing, which can fit into a small volume, and the overall size of the final product can be reduced. flexible PCB eliminates the excessive use of wiring harnesses and connectors in the PCB.
Rigid plates add some restrictions in product design because they cannot be installed in a limited space. Circuit boards need to be vibration resistant in products that are often subjected to mechanical shock.
PCB are more suitable for this situation because they can be bent and wrapped if needed. They can survive the harsh temperature of -200 to 400 degrees Celsius. Compared with traditional circuit boards, these functions make flexible circuit boards more reliable and durable.
Computers and accessories
Flexible PCB is very powerful in terms of signals and atmospheric conditions. The hard drive in the computer contains Flexible PCB. Because these PCB provides high data transfer rates on physically small circuit boards. Other electronic devices such as printers, calculators and laptop LCDs are usually designed with flexible PCBs for similar reasons.
Aircraft electronic systems are often filled with cables and are light in weight. A typical Airbus contains nearly 100 kilometers of cable, while a helicopter contains about 12 kilometers of cable. There is no compromise on the reliability and performance of aircraft systems. The flexible PCB reduces weight and can be significantly improved even when subjected to mechanical shocks, making it an ideal choice for aircraft.
Over time, automotive products have become more compact. Flexible PCB add compactness to their design. Because regardless of shape, these PCBs can be placed in a limited space and still work efficiently. Flexible PCB enables designers to produce lightweight products while maintaining product performance.
Flexible PCBs are commonly used in engine management computers, airbag controllers and other electronic components of automotive products. Since automobiles are often exposed to high temperatures, which is tolerable for flexible PCBs, these circuit boards have modern automotive products.
The mobile phone is small in size, but has many functions. Ever wondered how to design dense circuits in such a compact housing? The flexible PCB can realize the synchronization of multiple components, while requiring the least space.
Connecting wiring harnesses or rigid boards for synchronizing components is disadvantageous because of the limited size and shape of mobile phones. In addition, mobile phones will heat up, and traditional circuit boards cannot withstand high temperatures. In addition, PCB flexível also added waterproof function in the design.
Today, mobile phones and digital books are developing flexible PCBs, which is a major technological breakthrough. Imagine packaging a mobile phone or bending the pages of a digital book? It is not possible to use rigid PCBs. With the advancement of technology, flexible PCBs are also constantly developing, and we hope that in the near future, we will be able to bend the phone like a page.
Medical electronic products need to be highly accurate and durable. Wearable devices currently under development are usually developed using Flexible PCB, and its flexibility makes it suitable for host use.
Today, wearable devices are used to track health, and these gadgets are very compact and sophisticated. Flexible PCB can be implanted with sensors on the patient’s skin, and the results can be monitored on a smart watch or mobile phone. This revolution in wearable medical devices is brought about by flexible PCBs.
It is often necessary to place medical devices inside the human body. For example, cardiac pacemakers or pill cameras are often exposed to extreme atmospheric conditions and flexible PCBs are best suited for this situation.
Rigid PCBs are bulky and cannot adopt shape changes and low performance during high signal transmission, which makes them unfavorable for medical electronic products.
Recent research on Flexible PCBs has allowed scientists to develop Flexible PCBs that are more suitable for medical devices. These PCBs are developed using organic materials to provide more suitable quality for prosthetic components. Compared with flexible traditional PCBs, these circuit boards are more flexible, which is exciting for the development of high-performance prostheses.
Flexible PCBs have revolutionized sensors. Modern sensors are manufactured on flexible PCBs, which reduces their size. These sensors can be placed in limited and irregular spaces, suitable for design or more compact products.
Most modern military equipment uses flexível such as radar systems in military vehicles. The control system in military grade equipment requires high signal and robustness of the conductive path. Because equipment must be used at extreme temperatures, weather conditions often make it difficult to withstand rigid PCBs. In addition, military equipment is often affected by vibration and mechanical stress, which is easily tolerated by flexible PCBs. For these reasons, flexible PCB is best suited for military equipment.
