Waterproof NFC tag!NFC Label wholesale

How to make waterproof NFC tags. First, provide a flexible circuit board (FPC) as the carrier of the waterproof NFC tag, and inspect the flexible circuit board (S10). The purpose of the inspection is to confirm whether the flexible circuit board functions normally, and the flexible circuit board is selected to make the waterproof NFC The label can withstand bending. In this embodiment, the thickness of the flexible circuit board is between 0.1 mm and 0.12 mm.

Next, a plurality of electronic components are set on the flexible circuit board (S20), that is, the piece is printed. The electronic components that need to be installed include IC chips, NFC tags, capacitors and other components. In the preferred embodiment, NXP S50 IC is selected as the IC chip.

After the flexible circuit board and electronic components are set up, the functions of the electronic components are checked (S30), and it is confirmed that after the printing process, the flexible circuit boards and electronic components function normally, and the NFC-related functions must also be able to be used normally.

Furthermore, a waterproof film is provided, and the waterproof film is attached to the periphery of the electronic component. In this embodiment, the waterproof film is a polyester film, also called Mylar. The waterproof film is attached to the periphery of the electronic component, and its main purpose is to protect the connecting wire that the electronic component extends. The connecting wire is the component that is most easily damaged during the clothes washing process. Therefore, attaching the waterproof film can make the connecting wire of the electronic component Not affected by water, and can still be energized after being twisted.

After that, the electronic component is encapsulated with black glue (S50). In this embodiment, the electronic component is encapsulated by dispensing black glue, and the electronic component is encapsulated in the black glue. The black glue used is waterproof vinyl, which can avoid The electronic c
