Alcohol resistant QR code printing high temperature resistant labels
High temperature resistant label paper is based on polyimide film and is coated with special pressure-sensitive adhesive.
It has good chemical and abrasion resistance and can withstand temperatures up to 320°C.
Chemical substances such as detergents and cleaning agents have a certain antiseptic effect.
And can maintain excellent performance in extremely harsh environments of high temperature and wear.
It is mainly composed of three parts: substrate, adhesive and release paper.
SMT Label.1
High temperature label paper designed for character or barcode labels on printed circuit boards
Because it can withstand the erosion of solder, flux, etc. encountered in the production of printed circuit boards.
The thickness is mainly 25um and 50um. Commonly used colors are matte white and bright white.
There are also some other custom colors like red, yellow, blue and green.
High temperature label stickers are widely used in SMT and crest process of many electronic products,
Mainboards, anti-corrosion products, mobile phones and lithium batteries and other products.
SMT Tag 1.1
High temperature resistant label paper is mainly used for barcode traceability in SMT process.
In each process node of SMT, it is necessary to collect the QR code information of each PCB board and register the status of each process.
In individual processes, not only the two-dimensional code is required to withstand high temperature
Moreover, the anti-alcohol scratching of the QR code requires that the QR code should not be blurred or faded after contact with alcohol.
In this case, you need to use alcohol-resistant resin ribbon to print the QR code
Solve the problem of anti-alcohol scratching of SMT traceable QR code.
