Copper cladding is to use the idle space on PCB as the datum plane and then fill it with solid copper. These copper areas are also called copper filling. The significance of applying copper is to reduce the impedance of ground wire and improve the anti-interference ability; Reduce voltage drop and improve power efficiency; Also, […]

Hai hi3518EV300 processor, as a new generation of consumer cameraSOC, integrates a new generation of ISP and the latest H265 video compression encoder in the industry. It leads the industry in low bit rate and high image quality. At the same time, it detects human figures and supports intelligent applications such as face and abnormal […]

Whether the amplifier gets current from this power supply or another power supply depends on the instantaneous polarity of the signal on the load. The current flows from the power supply, passes through the bypass capacitor, and enters the load through the amplifier. Then, the current returns to the ground plane from the ground terminal […]

Nowadays, the use of PCB multilayer circuit boards in the market has become a popular trend, and with the development of the industry, the ability of many PCB manufacturers to develop and produce PCB multilayer circuit boards has become increasingly prominent. So, what are the requirements for the proofing of PCB multilayer circuit boards? Below, […]

Printed circuit boards (pcbs) are generally called printed circuit boards (PCBs). Printed circuit board proofing means that a small amount of samples are produced for testing before mass production, which also answers the question of PCB proofing sold in the market. Many electronic product manufacturers will find some professional PCB proofing manufacturers to cooperate with, […]

Generally, there are two kinds of SMT processes, one is lead-free process and the other is lead-containing process. Everyone knows that lead is harmful to people, so lead-free process meets the requirements of environmental protection and is the general trend. Shenzhen Yingcheng Electronic SMT SMD foundry adopts lead-free technology. The difference between lead-containing process and […]

In fact, the displacement of components in smt processing is a bad phenomenon in SMT factory. With the development of science and technology and the improvement of people’s living standard, the pursuit of electronic products is becoming more and more miniaturized and precise. However, the traditional DIP plug-in in SMT small batch chip processing factory […]

For some customers, the design of PCB is seriously nonstandard, and they simply can’t tell whether it’s pad or via. Sometimes conductive holes are treated with pad, and sometimes key holes are treated with via. The design confusion leads to more errors. According to incomplete statistics, the problems caused by nonstandard design account for more […]

Gas reflow welding is also called condensation welding. VPS refers to SMT SMD welding equipment that uses the latent heat released by the vaporization of fluorocarbon liquid as a heat medium to provide heat for welding. First-phase reflow thick film circuit. 1. The principle of gas-phase reflow soldering is that the liquid containing fluorocarbon can […]

In fact, the micro-assembly technology of SMT proofing and small batch processing is a comprehensive technology of assembling various micro-components of electronic circuits on high-density multilayer interconnected substrates by micro-welding and SMT chip processing to form micro-electronic products. I. Multi-chip module The multi-chip component in SMT package is a kind of high-tech electronic product derived […]
