The temperature-sensitive liquid crystal coating layer 3 is tightly combined with the PCB base layer 1. The temperature-sensitive liquid crystal coating layer 3 has a unique molecular structure, and the molecular arrangement state is extremely sensitive to temperature and humidity changes. When the temperature of the environment where the PCB base layer 1 is located changes, the arrangement of the temperature-sensitive liquid crystal molecules will adjust accordingly, thereby causing changes in the optical properties of the coating layer and presenting different colors. During the operation of the equipment, the temperature and humidity information of the environment where the PCB board is located can be directly obtained by observing the color or shape change of the coating layer of the PCB label. Once the environmental parameters exceed the appropriate range, the temperature may be too high to cause the performance of electronic components to decrease or even be damaged, and the humidity may be too high to cause short circuit, corrosion and other risks. Therefore, potential problems can be detected in time, and targeted measures can be taken to strengthen heat dissipation, improve ventilation and reduce humidity, thereby effectively ensuring the stable operation of the equipment, reducing equipment failures caused by environmental factors, and improving the reliability and service life of the equipment.
