High - temperature labels are mainly used in the process of surface mounting of circuit boards and electronic circuits, with relatively frequent applications.

When used on circuit boards, they are mainly used to identify the board's serial number and function, which facilitates warehouse entry and exit or packaging. After the data is entered with a barcode scanner, it is very convenient to know all the production processes of the circuit board.

In the surface - mount process of electronic circuits, thermal transfer printing can be used, and it shows the best and first - class reading rate. Even if the label board is directly removed from an environment with soldering flux, the label can still resist dirt. If the label is pre - heated, it can further resist various chemical substances such as soldering fluxes, melting agents, and cleaning agents, as well as extreme environments of high temperature and wear, ensuring good performance in various extremely harsh application environments.

In the process of SMT patch installation, high - temperature labels are indispensable for recording relevant data. Therefore, in the process of circuit board printing and electronic circuit surface treatment, high - humidity labels are one of the labels that must be used.
