On the market, most of the popular NFC tags are implemented as Dry/Wet Inlay, Paper Sticker and PET sticker, but among them, their production process is to attach the wafer to the substrate through conductive glue, so through the test of washing water, most of these labels are washable for about 3 to 10 times.

Dianchain's most NFC PCB FPC is generally temperature resistant to 150 ° C for 3 hours. Now the temperature-resistant coating of the product has been tested and explored. The highest instant temperature resistance of customized PCB and FPC can reach 270℃~280℃.
