PCB circuit board is the support of circuit components and devices in electronic products. Even if the circuit schematic design is correct, the printed circuit board is not properly designed, which will adversely affect the reliability of electronic products. When designing printed circuit board, we should adopt correct method, abide by the general principle of [...]

With the development of science and technology and the continuous development of smart phone technology and wearable electronic technology, Intelligence, thinning and lightening, and miniaturization have become the mainstream. Consumers will also have higher and higher quality requirements for their products. Well, as manufacturers of laser marking machines, the quality control of internal PCB boards is also [...]
PCB refers to the circuit board, and PCBA refers to the circuit board plug-in assembly, added SMT and DIP process. PCB is a bare board, and PCBA is a finished board. A printed circuit board (PCB) is called a "printed circuit board." It is made of a glass epoxy resin material. According to the [...]
In general, the copper foil distribution on PCB board is very complicated, and it is difficult to model accurately. Therefore, it is necessary to simplify the shape of wiring and make the electronic components on the board of ANSYS model, which are close to the actual circuit board, to be simulated by simplified modeling, [...]
1.The solderability of the circuit board hole affect the quality of welding The solderability of the circuit board hole is not good, and it will cause the false weld defect, which will affect the parameters of the components in the circuit, leading to the instability of the multilayer component and the inner layer wire, [...]
The Development of China’s printed Circuit Board Industry will enter the period of High Speed growth
With the rapid development of electronic products, the price war has changed the structure of supply chain. China has become the most important PCB manufacturing base in the world because of its industrial distribution, cost and market advantages. The output value of China's printed circuit board industry has maintained the position of first in the [...]
Prior to the advent of PCBs, the interconnections between electronic components were made by directly connecting electrical wires. To simplify wiring, people printed circuit patterns on the substrates and formed pathways through copper plating. As a result, printed circuit boards came into being. Has now developed into a cornerstone of the electronic information industry. [...]
The ceramic circuit board industry has long been developing for many years and has already matured. The overall market pattern has long been clear. Compared with other PCBs, the ceramic circuit board is an alternative to the old generation of substrates, which can perfectly replace the metal substrate and the transparent substrate. Because of [...]
According to sources, iphone's new OLED iPhone has decided to reduce the use of rigid-flexible printed circuit boards (RFPCBs) to replace the more expensive and less advanced multi-FPCBs. The South Korean website The Investor reported that RFPCB is a key component for connecting iPhone X embedded chips and panels, and the touch panel of [...]
Under the influence of globalization, the division of labor in the industrial chain internationalization is becoming more and more clear. With the advantage of labor force and capital, China is gradually occupying the leading power in the low end of the industrial chain. China is the largest producer of PCB in the world, but [...]
