In addition to being used in printed circuit boards, high - temperature labels are also used in the SMIT devices of many electronic products. Devices such as motherboards, corrosion products, mobile phones, and lithium - ion batteries use these labels, which can not only ensure that the markings on the labels remain stable for a long time and are clearly visible. Moreover, during the high - temperature operation of these electronic products, the markings on the labels will not be lost.

During the long - term use of high - temperature labels, people's requirements for such labels are constantly changing. In addition to maintaining the original features, people have also made improvements in aspects such as the color, luster, and aesthetics of the labels. Especially in terms of the background color of the labels, using characters of different colors on labels with different background colors can prompt users with different levels of information. Moreover, the usage environment of many high - temperature labels has also changed. Mainly after the adoption of new technologies, there can be many different types of aesthetics and luster in the labels. In daily use, people can achieve more operational purposes with the help of these labels. Now, some school supplies or office supplies have also started to use these high - temperature labels.
