Sometimes customers often wonder what the process flow of PCB is, and even some peers who are new to the industry are confused. When making an inquiry, customers often say that the board is very simple, and you can tell the price. In fact, the process of PCB depends on the number of layers, vias, [...]
There are several real reasons: 1. Most importantly, in the UV exposure process of solder resist layer, the pigment needs to not absorb ultraviolet light as much as possible. The selection of pigments with stable high temperature performance, good affinity with solvents and meeting various electrical specifications is limited. Green, blue and red solder resist [...]
With the rapid development of large-scale infrastructure and industrialization in China, the output and consumption of aluminum profiles have increased rapidly. Now it has become a world-class aluminum profile production base and consumer market. China's industrial aluminum profiles account for about 30% of the total application of aluminum profiles, which are mainly used in automobile [...]
Convenience Principle Potentiometers, adjustable capacitors, key switches, adjustable inductors and other regulating devices are often used in the design of circuit boards. We may adjust these devices after designing the whole circuit board, Some devices such as keys may also become the opening keys of the circuit board. Therefore, when designing such devices, they should [...]
1. Manual visual test Manual vision testing is to confirm the component mounting on PCB through human vision and comparison. This technology is one of the most widely used online testing methods. However, with the increase of output and the reduction of circuit boards and components, this method is becoming more and more unsuitable. Low [...]

PCB circuit board is the basic electronic component of all electronic circuit design. As the main support, it carries all the devices that make up the circuit. The function of PCB is not only to combine scattered components, but also to ensure the regularity of circuit design and avoid the confusion and errors caused by [...]
These details require attention when welding flexible sleeves The diameter and length of the bolt connecting the flange shall comply with the standard. After tightening, the length of the bolt protruding from the nut shall not be greater than the diameter of the bolt. After the installation of threaded flexible casing, there shall be 2-3 [...]
Variable frequency drive (VFD) is a power control equipment that uses frequency conversion technology and microelectronics technology to control AC motor by changing the working power frequency of motor. It is also one of the essential equipment in various industrial and commercial occasions today! In power quality assessment, frequency converters are typical harmonic source loads. [...]
