The standard for electrical equipment for medical laser film usually specifies temperature rise rather than temperature.The following factors should be considered when determining the measurement method and allowable temperature rise in such standards, such as structural characteristics, thermal conductivity and thickness of insulating medical laser film, detectability of each part of insulating medical laser film, ventilation method, load characteristics, etc.In the circuit board manufacturing industry can be used for electronic protection paste, especially for SMT temperature protection, electronic switch, PCB board gold finger protection, electronic transformer, relay and other electronic components that need to withstand high temperature and moisture protection.How do you choose good or bad medical laser film?Actually, the glue quality of medical laser film has two standards in use, one is the initial adhesive force, one is the holding force, the two are inversely proportional.Under normal circumstances, the adhesive force is less than 10 medical laser film is glue coating less, generally only about 20 microns, such as stationery medical laser film, general promotional bundled with medical laser film.The initial adhesive force of normal sealed medical laser film is between 15 and 20. The thickness of this medical laser film glue is usually 22 to 28 microns.It's a standard thickness.But at present the medical laser film on the market is mixed with most of the impurities, so the thickness is increased, to cover impurities, glue also mixed with color powder, so transparent medical laser film appeared egg yellow, light green, this kind of medical laser film is generally inferior.What are the characteristics and classification of industrial medical laser film?
