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 [...]
Hexagon socket bolts are also called cylindrical head hexagon socket bolts and hexagon socket screws. Commonly used levels are 4.8, 8.8, 10.9, and 12.9. Hexagon socket bolts are generally selected for grade 8.8, 10.9 and 12.9 when used on aluminum profiles, and the material is mostly carbon steel. However, in order to meet market demand, [...]
The small class mentioned the content of PCB in the previous sharing, so what is the connection between switching power supply PCB wiring and ripple? Let's share the relationship between the PCB wiring and ripple of the switching power supply, and the reasons for the ripple of the switching power supply. Damaged power plug 1. [...]
When entering a pcb factory, the most common ones are red PCB, green PCB or blue PCB. A small amount of black PCB. Among them, the usage rate of the first three colors is the highest. The boards between different colors have What's the difference? PCB, as a printed circuit board, mainly provides interconnection between [...]
