With the miniaturization of various smart products, the density of components on circuit boards is increasing. In order to improve the quality of circuit boards, strict product tests and quality inspections must be passed before they leave the factory. X-ray inspection equipment is mainly used to detect process defects of circuit boards and find out [...]
For precision parts, processing is very strict. The processing program includes cutting in, cutting out, etc. There are specific requirements for size and accuracy, such as how many micrometers are floating up and down 1mm. If the size difference is too large, it will become waste at this time, which is equivalent to reprocessing. This [...]
As a new type of sensor, the optical fiber sensor has the incomparable advantages of traditional sensors, such as: high measurement accuracy, large measurement dynamic range, fast response speed, immunity to electromagnetic interference, explosion-proof, flame-proof, anti-corrosion, easy long-distance measurement and Reuse, small size, simple structure, high mechanical strength, etc. In the early days, optical fibers [...]
With the development of science and technology, the requirements for soldering processes in electronic processing are getting higher and higher. The soldering process of traditional soldering soldering machines can no longer meet the precision welding of some small devices. At this time, laser soldering machines can just make up for the shortcomings of traditional soldering [...]
Due to the complex process flow of PCB manufacturing, in the planning and construction of intelligent manufacturing, it is necessary to consider the related work of process and management, and then carry out automation, information and intelligent layout. EDA365 Electronic Forum 1 Process classification According to the number of PCB layers, it is divided into [...]
In daily life, our common circuit boards include ceramic circuit boards, alumina ceramic circuit boards, aluminum nitride ceramic circuit boards, circuit boards, PCB boards and so on. The progress of electronic life means the progress of the circuit board industry. When the circuit board passes through the production line, the company will inspect the performance [...]

Each company has some differences in the design of materials. Generally, the definition of materials focuses on the setting of the glass transition point. But for the long-term temperature resistance, it is only necessary to meet the standard, so the quality requirements in this regard are all Different. For long-term temperature resistance, most FR-4 materials [...]
One of the goals of photovoltaic technology development is to continuously improve the efficiency of solar cells and reduce costs. Among them, one of the requirements of the front metalization process of solar cells is the quality of fine line printing, that is, reducing the width of the grid line from 30μm to 25μm, 20μm, [...]
The purpose of the detection of the printed circuit board: to detect whether there is a PCB on the conveyor belt. Application: Because the reflectivity of the PCB board is very different, it is very unreliable to detect with a direct-reflection sensor. The VS1 focusing sensor has high gain and can reliably detect each circuit [...]
