PCB engineers refer to senior engineering and technical personnel engaged in research, teaching, product design, scientific and technological development, production and management of various electronic equipment and information systems. Generally divided into hardware engineers and software engineers. Hardware Engineer: mainly responsible for circuit analysis and design; and PCB layout design with computer software as a…
In PCB manufacturing all over the world, there are billions of printed circuit boards out of the factory. And in every day’s life, there are tens of millions of tons of waste PCB scrap accumulation. Once the circuit board is abandoned, it will do great harm to our ecological environment and human health. No matter…
Affected by the wrong deletion of schematic diagram, set the automatic backup function of PCB immediately. Different from schematic backup, the format of PCB backup file and source file is the same, but the name is different. This name is set by us. The steps are as follows: Click “setup” – > “user preferences” to…
Printed circuit board (PCB) is the blood of electronic products. It is the key component of supporting, loading and connecting electronic circuits. It is an important component of most electronic equipment and products that can not be ignored. PCB can be divided into rigid pcb, flexible PCB and rigid flexible PCB according to the degree…
The packaging of PCB board has a very small proportion in the manufacturing process of custom PCB manufacturing factory. The main reason is that it does not produce added value on the one hand, and on the other hand, the Chinese manufacturing industry does not pay much attention to the packaging of products. In this…
The signal with PCB change (such as step signal) propagates from a to B along the transmission line, and the coupling signal will be generated on the transmission line C-D. once the changed signal ends, that is, the signal returns to stable DC level, the coupling signal will not exist. Therefore, crosstalk only occurs in…
In PCB manufacturing, it is necessary to punch and cut according to certain specifications. If each operation needs mold or protection board, it is too troublesome and inefficient. It is easier to use laser cutting. Laser cutting mainly includes carbon dioxide laser (CO2 laser) and ultraviolet laser (UV laser). Let’s take a look at their working…
Even if the trend of PCB manufacturing and usage is small, it will also affect consumers. Although there may be more time, the following four main technology trends are expected to maintain the leading position in the PCB market for a long time and lead the whole PCB industry to different development directions. 1. High…
There is no doubt that printed circuit board (PCB) is a milestone tool in human technology. Why? This is because it is hidden in every electronic device today. Like other great inventions in history, PCB is also gradually mature with the progress of the historical wheel. Up to now, it has a history of 130…
At present, with the requirement of PCB size becoming smaller and smaller and the requirement of device density becoming higher and higher, the difficulty of PCB design is gradually increasing. How to shorten design time while ensuring quality? This requires engineers to have excellent technical knowledge and master some design skills. Determine the number of…
How often do you start the PCB development process and are bothered by time-consuming management tasks? Once ready for production, a design review and correction of DFM issues will be required, which will take your own time. With the acceleration of product development progress and the shortening of product life cycle, the pressure of increasing…
Do you know “why PCB must be baked before SMT passes the reflow oven after the expiration date of PCB”? The main purpose of PCB baking is to remove moisture and moisture, and to remove moisture contained in PCB or absorbed from outside, because some PCB materials can easily absorb water molecules. In addition, PCB…
Recently, the upstream materials of PCB have been rising one after another, except that the international copper price has been breaking through 7000 US dollars and approaching 8, In addition to the $000 mark, the supply and demand of electronic grade glass fiber cloth and glass fiber yarn are also reversed. After the third quarter…
Recently, we encountered a PCB leakage problem. The cause is a low-power product. The current of UA level of the whole machine was aged at room temperature for a period of time. After using it for a period of time, it was found that the power consumption of individual sample machines even reached Ma level.…
In the design of PCB, the ESD resistance design of PCB can be realized by layering, proper layout and installation. In the design process, most of the design modifications can be limited to the increase or decrease of components by prediction. By adjusting PCB layout and wiring, ESD can be well prevented. Static electricity from…
