Description

Waterproof NFC Tag

This creation is about an NFC tag, especially an NFC tag with waterproof and twist resistance.

With the development of technology, smart devices have begun to infiltrate into the lives of modern people. Smart phones, bracelets, home appliances, etc., and even textiles or wearables have also begun to develop intelligently, that is, smart clothing. However, in the field of smart clothing, it is a problem that smart clothing must be more able to adapt to harsh environments than general smart devices, especially waterproof, sun-resistant, flexible and other characteristics, especially the clothing itself must be Durable, especially to withstand the cleaning process. And the electronic components (NFC tags, antennas, ICs, etc.) on smart clothing must also have corresponding durability. Conventional electronic components cannot be cleaned, and they are prone to short circuits and malfunction when they encounter water. In addition to waterproofing, clothing is often twisted and twisted many times during the washing process. Even if the electronic components do not encounter water failure, they are easily damaged during the twisting process. Therefore, how to place the electronic components on the clothes and be able to withstand the harsh environment under clothes washing is the first problem to be overcome. At present, a relatively common practice in the market is to encapsulate electronic parts into buttons so that clothing can correspond to intelligent functions. However, the button method requires the use of additional mold manufacturing, which greatly increases the manufacturing difficulty and cost, and is easy to drop and lose. There are still many defects to be overcome. Therefore, how to properly attach electronic components to clothing is worth thinking about by those with ordinary knowledge in the art.

In view of the above problems, this creation provides a waterproof NFC tag. The beneficial effect of this creation is that it has the characteristics of waterproofness and elasticity, and is suitable for being applied to smart clothes. This creation provides a waterproof NFC tag, which includes a back part, a central part, and a film part. The adhesive part includes an antenna element. The central part includes an IC chip and an NFC tag. The IC chip and the NFC tag are packaged in a black plastic. The thin film portion is provided around the central portion and includes a plurality of connection lines. The IC chip and the NFC tag are connected to the antenna element through the connection lines. It is characterized in that the central portion and the film portion are disposed on the adhesive back portion. The above waterproof NFC tag is characterized in that the thickness of the waterproof NFC tag is 0.6 mm. The aforementioned waterproof NFC tag is characterized in that the film portion is covered with a polyester film.

After the setting of the flexible circuit board and the electronic components is completed, the function of the electronic components is checked (step S30), and it is confirmed that the flexible circuit board and electronic components function normally after the printing process, 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 affixed to the periphery of electronic components. Its main purpose is to protect the connecting wires extending from the electronic components. The connecting wires are the most easily damaged components during the laundry washing process. Therefore, attaching the waterproof film can make the connecting wires of electronic components It is not affected by water and can still be powered normally after being twisted. After that, the electronic components are encapsulated by using black glue (step S50). In this embodiment, the electronic components are encapsulated by using a dot of black glue, and the electronic components are encapsulated in the black glue. The used black glue is waterproof black glue. Prevent electronic components from being affected by water, thereby achieving waterproof function. Next, the black rubber is dried (step S51). In this embodiment, natural drying is used to allow the black rubber to be shaped and protect the electronic components. After the electronic component is packaged, a backing adhesive is formed behind the electronic component (step S60). The backing adhesive is composed of a large area of black adhesive. As the main structure of the waterproof NFC tag, it supports the main components of the waterproof NFC tag. In this embodiment, the adhesive further includes an antenna element. After the adhesive is completed, check the function of the electronic component again (step S70), and confirm whether the electronic component is damaged in the foregoing process. Under normal circumstances, the function of the electronic component must be functional, and the related functions of the NFC tag must be maintained. Afterwards, a visual inspection is performed (step S80) to check whether the appearance of the waterproof NFC tag is complete. Please refer to FIG. 2A and FIG. 2B. FIG. 2A and FIG. 2B show the waterproof NFC tag of the present invention. The original waterproof NFC tag 100 includes a backing portion 110, a film portion 120, and a central portion 130.
