Method for manufacturing radio frequency tags with hot and cold stamping technology

Abstract

The invention discloses a manufacturing method of radio frequency tags, and the radio frequency tags are manufactured with a hot and cold stamping technology; the process method has the steps that: polyvinyl chloride (PVC), polypropylene (PP), polyethylene terephthalate (PET), paper, plastics and the like are adopted as base materials, and electro-metal stamping foils are stamped on the base materials by a stamping machine through a hot stamping or cold stamping technology, then waste is discharged from other parts of the metal foils, and antenna patterns are obtained; and if coil antennas are to be manufactured, insulation layers need to be paved on coils, the electro-metal stamping foils are stamped on the insulation layers and are connected with the ends of the antennas to form bridges, i.e. radio frequency antennas. Finally, chips are reversely pasted on the antenna bridges, coated and packaged, and radio frequency tags are obtained. A traditional radio frequency tag process has the disadvantages of too high cost, complicated process, long production time, certain pollution to the environment and the like, and the method for manufacturing radio frequency tags with the hot and cold stamping technology can effectively reduce the radio frequency tag manufacturing cost, simplify the complicated process, and meet the market demand for the low-cost radio frequency tags.

Description

technical field [0001] The invention relates to a method for making a radio frequency label, in particular to a method for making a radio frequency label by hot stamping or cold stamping technology. Background technique [0002] Radio Frequency Identification (RFID) technology is a wireless automatic identification technology and an innovation of automatic identification technology. The radio frequency identification system includes the front-end radio frequency part and the background computer information management system. The radio frequency part is composed of a reader and a transponder. The transponder is implanted with an IC chip. The transponder and the reader / writer transmit and exchange information through electromagnetic waves. Radio frequency identification technology has many advantages and is widely used in transportation, logistics, security, anti-counterfeiting and non-contact integrated circuit (IC) cards, etc. [0003] Both the reader and the transponder ne...

Problems solved by technology

[0010] The conductive ink method to prepare radio frequency identification antennas has been widely used in recent years. The reason is that the conductive ink method omits many processes of foil covering, printing resist ink, etching, and removing the resist ink layer, and adopts screen printing and gravure printing. Directly print the conductive ink on the substrate according to the pattern designed by the antenna. Compared with the traditional etching method, it greatly shortens the production process and reduces the environmental pollution during the production process. However, the conductive medium of the conductive ink is silver powder or carbon powder. high production cost

[0011] The above three processes all involve the manufacture of radio frequency antennas on material substrates such as PVC, PET, paper and other substrates, and then package radio frequency cards and radio frequency electronic tags. However, each process involves relatively expensive materials and complicated manufacturing processes. The production cost is relatively high, and it is sometimes difficult to meet the requirements of the product using the above-mentioned process
