Introduction to paper RFID electronic label manufacturing process and material application

RFID (Radio Frequency Identification) electronic tag is a smart tag that transmits information and identifies through radio frequency signals. Its production process involves multiple steps and the use of multiple materials.

The production process of paper RFID electronic tags mainly includes the following steps:

Chip preparation: The core of the paper RFID electronic tag is the chip, and the preparation process involves the design, etching, deposition and testing of the chip. These chips are manufactured using CMOS processes, including steps such as wafer dicing, circuit design, photolithography, etching and metal deposition.

Paper RFID electronic label manufacturing process and material application introduction

Antenna manufacturing: The antenna is an important part of the paper RFID electronic tag used to receive and transmit radio frequency signals. Usually made of conductive materials (such as aluminum, copper) through printing or etching techniques. The manufacturing process includes design, printing, calibration and testing.

Packaging assembly: The chip and antenna are assembled on the label substrate and packaged to protect the circuit from environmental influences. Encapsulation typically uses an adhesive or encapsulating material to hold the components together through bonding or heat compression techniques.

Label printing: Print identification information, barcodes or QR codes on the label film. Printing processes include digital printing, thermal transfer printing and inkjet printing, etc., used to print the necessary information on the label surface.

Testing and quality inspection: After production is completed, radio frequency performance testing, identification information reading and writing testing, and appearance quality inspection are required to ensure that the function and quality of each electronic tag meet standards.

The application materials of paper RFID electronic tags mainly include the following:

Chip material: Chips usually use silicon materials, and metal films, polymers, etc. are also used as different layers and components of the chip during the production process.

Antenna material: Antenna materials are generally made of metals with excellent electrical conductivity, such as aluminum, copper or silver, and are applied to the substrate through printing, etching or spraying processes.

Packaging materials: Packaging materials need to have good wear resistance, temperature resistance, and chemical corrosion resistance. Commonly used materials include polyurethane, epoxy resin, polyester film, etc.

Label film material: Label film is mostly made of plastic materials, such as PET (polyester film), PVC (polyvinyl chloride), etc., which are wear-resistant and flexible.

The production process and material application of paper RFID electronic tags is a complex and delicate process involving a variety of materials and process steps. The manufacturing process and material application of paper RFID electronic tags are constantly innovative and developed, making them widely used in various fields. From supply chain management to retail, healthcare, smart logistics, smart cities and other fields, RFID tags have become a key Tool to improve efficiency and optimize management.
