In the process of PCBA processing, reflow soldering is a very important process, which will be divided into three dimensions: basic concept, process flow and process characteristics. PCBA reflow soldering has good manufacturability, and there are no special requirements for the layout position, direction and spacing of components. The layout of components on reflow soldering […]

In the manufacturing process of PCB, one of the most basic and critical processes, whether it is single-panel, double-panel or multi-panel, is graphic transfer, that is, transferring the Art-work graphic to the copper-clad substrate. Graphic transfer is the key control point in production, and it is also the technical difficulty. There are many technological methods, […]

The topic of intelligent vehicle development continues to be hot, especially after the green transportation boom of all-electric EV vehicles, and the demand for electronic design, such as autonomous driving, networked vehicles, and active/passive vehicle safety, is stimulated. Not only is the development of new technologies maturing, but the demand for automotive electronic PCB required […]

1. Overview of embedded hardware circuit design With the development of Internet of Things and artificial intelligence technology, our life is becoming more and more intelligent and informative. Smart phones, smart bracelets, smart locks, smart refrigerators, autonomous driving, robots and other smart products are emerging one after another, and human beings are about to enter […]

The layout of PCB Layout design is described from three aspects: right-angle layout, differential layout and serpentine: I. Layout design right-angle routing (three aspects) The influence of right-angle routing on the signal is mainly reflected in three aspects: first, the corner can be equivalent to the capacitive load on the transmission line, slowing down the […]

1.layout design PCB wiring and layout isolation criteria: strong and weak current isolation, large and small voltage isolation, high and low frequency isolation, input and output isolation, and the demarcation standard is one order of magnitude difference. The isolation method includes: the space is far away and the ground wire is separated. 2. The crystal […]

Circuit board simulation is no longer an option but an inevitable way for most layout designs today. EDA industry is the key factor to promote the rapid development of the global electronic industry, and its market size is as high as $1 trillion. Most of the sales are monopolized by several big companies (measured by […]

When it comes to outsourcing, the first thing that people think of is to send products or parts that they can’t or don’t want to produce to other factories for OEM. In fact, driven by the increasingly fine social division of labor, modern outsourcing is not only the outsourcing of products, but also the initial […]

Drilling jig is one of them, but 90% of the jigs have been wave welded. This kind of jig is made of hard computer gongs, and some can move the twist drilling equipment or other drilling devices to the position of each hole accurately by moving the mold. A typical practice is to leave a […]

However, compared with developed countries, China’s developing PCB automation equipment industry still has a certain gap. However, among developing countries, China is the largest and most complete country with the strongest comprehensive strength in PCB automation equipment industry. When well-known foreign PCB automation equipment enterprises take root in China, even with the continuous progress of […]
