What is PCB anti-metal label

In the practical application of RFID, the metal surface will form a shield for conventional RFID tags, resulting in the problem of being unable to read and write data. In order to overcome this problem, PCB anti-metal labels came into being. We will give you a detailed introduction around the definition, characteristics, materials, advantages, costs and application scenarios of PCB anti-metal labels.

PCB anti-metal tag, the whole process is Printed Circuit Board Anti-Metal Tag, which is a special RFID tag based on printed circuit board technology. It adopts specific structural design and material selection to work on metal surfaces and realize the reading and writing functions of metal tags.

1. Characteristics of PCB anti-metal labels:

1. Anti-metal interference: PCB anti-metal tags have excellent anti-metal interference capabilities and can work normally on metal surfaces to achieve stable data transmission.

2. High-frequency communication: PCB anti-metal tags mostly use ultra-high frequency (900MHz) communication, which has long communication distance and high-speed data transmission capabilities.

3. Highly customizable: PCB anti-metal labels can be customized according to the needs of different application scenarios, including adjustments in size, shape, chip type, antenna design, etc.

4. Long life and durability: PCB anti-metal labels are made of durable materials, with long service life and wear resistance.

2. Material of PCB anti-metal label:

The main materials of PCB anti-metal tags include: PCB circuit board: As the main structure of the tag, it generally uses organic polymer materials, glass fiber FR-4 reinforced hard materials + epoxy resin substrates, which can withstand harsh environmental conditions. use. Antenna: Made of conductive material (such as copper), it connects the data transmission between the chip and the tag and provides reading and writing functions.

3. Cost of PCB anti-metal labels:

The cost of PCB anti-metal labels is relatively high, compared with paper electronic labels. The main factors include material cost, production process and customization requirements. However, with the advancement of technology and the growth of market demand, and with the realization of economies of scale, costs are expected to gradually decline and become more competitive.

4. Application scenarios:

Asset MANAGEMENT: In the industrial world, asset management is crucial to a company's productivity and cost control. PCB anti-metal tags can be applied to the tracking and management of important equipment, providing real-time location monitoring and status updates.

logistics and supply chain: In logistics and supply chain management, metal containers and containers are common, and traditional RFID tags cannot be directly applied to metal surfaces. PCB anti-metal labels can track and control logistics links and improve logistics efficiency and accuracy.

Equipment maintenance: PCB anti-metal labels can be used in equipment maintenance management to facilitate the implementation of preventive maintenance plans, record equipment maintenance history and provide maintenance guidance information.

As the key to breaking through metal barriers in the Internet of Things, PCB anti-metal tags have the characteristics of anti-metal interference, high-frequency communication, and high customization. It has broad application prospects in many fields such as asset management, logistics and supply chain, equipment maintenance and smart retail. Although the cost is relatively high, with the development of technology and the growth of market demand, PCB anti-metal labels will gradually become an indispensable and important component in IoT applications.
