pcb characteristics

PCBs are being used more and more widely because they have many unique advantages, roughly as follows.


Can be densely packed


Over the years, the high density of printed boards has been able to evolve accordingly with the increased integration of integrated circuits and advances in mounting technology.


High Reliability


Through a series of inspection, testing and aging tests and other technical means, PCBs can be guaranteed to work reliably for a long period of time (generally 20 years of use).


Designability


The requirements for various properties (electrical, physical, chemical, mechanical, etc.) of the PCB can be achieved by standardizing and standardizing the design, etc. This results in short design time and high efficiency.


Producibility


PCBs can be standardized, scaled (in volume), and produced automatically with modern management, thus ensuring consistent product quality.


Testability


The establishment of a more complete test methods, test standards, through a variety of test equipment and instruments, etc. to detect and identify the PCB product qualification and service life.


Assemblability


PCB products are easy to standardize the assembly of various components, and can also be automated and mass-produced on a large scale. In addition, the PCB and various other components for the overall assembly, but also to form a larger part, system, up to the whole machine.


Maintainability


Since the components of the overall assembly of PCB products and various components are designed and produced on a standardized scale, these components are also standardized. Therefore, in case of system failure, they can be replaced quickly, easily and flexibly, and the system can be restored to work quickly.

PCBs have other advantages, such as making the system miniaturized and lightweight, and high-speed signal transmission.

PCB Functionality

PCBs have the following functions in electronic devices.


(1) To provide mechanical support for fixing and assembling various electronic components such as integrated circuits, to realize the wiring and electrical connection or electrical insulation between various electronic components such as integrated circuits, and to provide the required electrical characteristics.


(2) To provide solder resist graphics for automatic soldering, and identification characters and graphics for component insertion, inspection, and maintenance.


(3) electronic equipment using printed circuit boards, due to the consistency of similar printed circuit boards, to avoid errors in manual wiring, and can achieve automatic insertion or placement of electronic components, automatic soldering, automatic detection, to ensure the quality of electronic products, improve labor productivity, reduce costs, and facilitate maintenance.


(4) In high-speed or high-frequency circuits to provide the circuit with the required electrical characteristics, characteristic impedance and electromagnetic compatibility characteristics.


(5) Printed boards with passive components embedded inside provide certain electrical functions, simplify electronic installation procedures, and improve product reliability.


(6) In large-scale and ultra-large-scale electronic packaging components, it provides an effective chip carrier for miniaturized chip packaging of electronic components.
