  High-frequency transformers will produce copper loss and iron loss during operation. These two losses are finally converted into heat energy, which makes the iron core and winding of the high-frequency transformer heat up and the temperature rises. In addition, the windings also generate heat through current. When the heat of the high-frequency transformer is dissipated to the environment to reach thermal equilibrium, the temperature of each part of the high-frequency transformer should be a stable value. If the temperature of each part of the high-frequency transformer exceeds its allowable range for a long time, especially when the oil temperature of the high-frequency transformer is higher than normal by more than 10℃ or the temperature is still rising, the insulation of the high-frequency transformer is easy to be damaged, and it is easy to be damaged. High voltage breakdown causes malfunction or accident. Therefore, during normal operation of the transformer, it is not allow...

  If there is a way to ensure that the product is reliable, it is to ensure the predictability of its PCB, which is an important part of the product. In fact, PCB is the core component in almost all electronic products (from phones to computer systems) today. From automobiles to national defense, from aviation to technology, PCBs are ubiquitous in any industry. In all these industries, product reliability is of paramount importance. Whether it is medical technology or aviation technology, any mistake can cause huge losses. Similarly, in the medical field, equipment failure can have terrible consequences, leading to loss of life. This requires rewriting the traditional predictability method. Traditional predictability methods are usually based on  physical inspection .  However, physical inspection has inherent disadvantages, that is, only external defects can be inspected. Another problem faced by physical inspection is that when the PCB is complex and has countless vias,...
