Printed Circuit Board (PCB for short) is an important part of electronic equipment, which realizes the function of the circuit by connecting electronic components and circuits together. The principle of printed circuit board mainly includes the following aspects: Basic structure A printed circuit board usually consists of a substrate, wires, holes, and pads. The substrate …
Thin-film circuits, also called flexible printed circuit boards (PCBs), house electronic components within layers of conductive and insulating materials. The conductive layer features a pattern of geometric shapes providing connections between the electronic elements without bulky wires. Flexible PCBs use the same parts as rigid PCBs, but their design allows for dynamic movement, smaller electrical …
Copper laying in PCB design is an important part of circuit board design. The so-called copper filling uses the idle space on the PCB as a reference plane and then fills it with solid copper. These copper areas are also called copper fillings. The significance of laying copper is to reduce the impedance of the ground wire, …
Material of PCB circuit board PCB circuit board substrates from PCB board prototyping manufacturers can be divided into several types based on quality, material, and fire rating: 94HB cardboard: The most common cardboard material, mostly used to make low-grade single panels, at a low price. Due to its non flame retardant effect, products with fire protection …
PCB prototyping refers to the production of a small number of sample PCB boards before formal mass production to verify the correctness of the circuit design, the rationality of the PCB layout, the reliability of the materials, and the feasibility of the process, etc., to modify or optimize the PCB board. Improve the quality and performance …
Today, radio frequency circuits are used in various electronic products, including medical, industrial control, and communication products. What is an RF Circuit Board? The frequency range of radio frequency is usually 300Khz-300Ghz. The signal above 300Khz is radio frequency, and the signal above 300Mhz is microwave. There is a considerable difference between radio frequency and …
FPC, the flexible printed board, also known as “soft board”. As the name suggests, the biggest feature of FPC is that it is soft enough. Compared with our conventional PCB hard board, FPC is very thin, bendable, and flexible, and can withstand millions of dynamic bending without damaging the wires. Arbitrary according to the space …

The entire power electronics industry, including radio frequency applications and systems involving high-speed signals, is moving towards solutions that provide increasingly complex functions in ever smaller spaces. Designers are faced with increasingly demanding challenges in meeting system size, weight and power requirements, including effective thermal management, which again starts with the design of the PCB. Highly …
Before printed circuit board design begins, designers should take some basic steps to ensure a successful project, such as management and scheduling. Time and resources must be allocated to the project, including buffers for design changes or bugs that require changes to the schematic and layout. All too often, PCB designers have to struggle to …
In the manufacturing process of the circuit board, the following two methods are usually used to solder the pins of the components to the circuit board: one is to directly solder each pin to the circuit board; the other is to paint the solder paste on the pins. Put the components and the circuit board …
