Installation diagram of RFID tag

RFID tags are composed of coupling elements and chips, each RFID tag has a unique electronic code, attached to an object to identify the target object, commonly known as electronic tags or smart tags.

There are various types of RFID tags, each with its own unique characteristics and application scenarios. Here are a few categories briefly introduced:

1. There are three types of power sources with or without batteries: active RFID tags, passive RFID tags, and semi-active RFID tags;

2. According to the tag job evaluation rate: low-frequency RFID tags, high-frequency RFID tags, ultra-high frequency RFID tags, Weibo tags;

3. Classified by tag packaging type: sticker type RFID tag, plastic packaging RFID tag, glass RFID tag, ceramic RFID tag;

4. Classified by influencing medium: anti metal RFID tags, anti liquid RFID tags;

In addition, there are some labels based on specific application scenarios, such as high-temperature resistant labels, corrosion-resistant labels, etc;

Based on different sizes and performance labels, as well as the markers to be identified, choose the appropriate installation method. The above pictures provide several commonly used and our multiple implementation installation plans.

1.
Adhesive label

To achieve maximum adhesion of adhesive labels, please try to implement the following process as much as possible:

ØUse alcohol or other solvents with equivalent efficacy to wipe the area where the label needs to be affixed, ensuring that there is no dirt, dust, oil stains, or other debris in this area. Even a small amount of debris can affect the adhesion of the backing adhesive;

ØDepending on the type of label, ensure that the adhesive backed side of the label is completely flat and the entire label has no curled edges or deformations; When preparing to stick, hold the edges of the label and remove the release layer to ensure that your fingers do not touch the adhesive backing;

Uneven label

The label is completely flat

ØStick the label in the preset position and press it firmly for 10 seconds to ensure that the remaining items are fully adhered, ensuring that the edges are not raised and the adhesive is firm;

ØAfter the installation of the new label is completed, it is forbidden to shake or attach force to the label within 30 minutes;

6.2Hanging label

ØHanging labels need to consider the hanging position, and under normal circumstances, try to minimize their shaking after hanging to prevent damage due to impact;

ØHang on the surface of metal objects and choose anti metal tags as much as possible to meet the reading requirements.

6.3Screw hole fixed label

ØChoose appropriate aperture screws or rivets, fix the label directly in the preset position, and pay attention to the installation tool's torque not being too large, which may easily break the hole edge; You can also choose labels with both adhesive backing and fixed holes for a more secure installation.

6.4Embedded tags

ØAccording to the size of the label, cut an embedded space. Experimental results have shown that a circular cavity is more conducive to the recognition of the label;

ØApply a layer of epoxy resin adhesive at the bottom of the embedded label;

ØLoad labels to ensure that the labels are as flush as possible with the surface of the embedded material body, in order to ensure the readability of the labels;

ØTowards labelsInject resin without any metal components into the surrounding grooves;

ØEnsure that the resin completely fills the gap between the label and the material;

ØConfirm the tag recognition performance with a handheld reader/writer;

ØCommon issues with label installation

1What kind of metal tags would be recommended?

In selecting tags for a specific application, many factors need to be considered, such as the price of the tag, the physical size and shape of the tag; But what needs to be considered more are the reading and writing distance and the material of the label, the material of the installation surface, the installation method, and the surrounding environmental factors (including metal, humidity, current, etc.), all of which are related to the durability and reading and writing performance of the label. To achieve high-quality and reliable label reading and writing performance, it is necessary to analyze multiple variables in the environment. You can quickly understand the parameters, performance, and applications of each label through the electronic label product manual.

2Why is there a certain difference between the read-write distance of tags and experimental data?

The label will be designed and adjusted according to the application environment, such as adding protective coatings or creating gaps to avoid direct installation of the label on metal. These practices may all reduce label performance, resulting in little difference between actual performance and the originally designed performance.

In most cases, tags will lose a certain read and write distance due to the impact of the application environment, especially when the tag is embedded in metal or installed in a multi metal environment. Ordinary tags will temporarily maintain a certain level of performance, but in order to achieve sustained and stable tag performance, it is necessary to choose tags that are compatible with the application environment. Our technical team will assist clients in optimizing label frequency based on their actual application environment.

3How to install labels on assets?

After ensuring the read-write performance of tags in harsh environments, the issue of installing tags arises one after another, which is also one of the biggest challenges in RFID applications. High performance metal tags can resist high temperatures or immersion in liquids, but the adhesive backing of the tag may not be able to withstand them. The most ideal application is to embed tags into assets, ensuring that the tags are not affected by the external environment to the greatest extent possible. However, in practical applications, embedded methods may not necessarily meet actual needs.

Adhesive backing is one of the most commonly used methods for installing labels, and a comprehensive and detailed analysis of the application environment is required when selecting adhesive backing. The extremely cold environment can also affect the performance of the backing adhesive and cause the label to become brittle and fragile, so it is necessary to fully consider the storage environment and temperature of the workflow of the label. Not all applications can use adhesive to install labels. Other commonly used installation methods include bolt fixing, tape hanging, or epoxy adhesive fixation. We have rich experience and application cases in label installation, and our products also support all the installation methods mentioned above.

4What are the potential sources of interference in the application environment?

Just because a label is not directly attached to metal does not mean it will not be affected by metal interference. If the asset around which the tag is installed is rich in metals, or if the asset passes through an environment where multiple metals are stored during movement, it is necessary to carefully judge the use of the tag to ensure stable and reliable performance.

5Can high-temperature resistant labels be used in all high-temperature applications?

not always. Many different applications require labels to resist high temperatures. For example, a label designed for use in a dry and hot environment cannot be used in high-temperature and high-pressure steam sterilization environments, nor may it necessarily meet other types of high-temperature applications. The high-temperature resistant series tags are designed for different types of applications, meeting RFID applications with different high-temperature requirements, such as vehicle painting workshops, medical high-temperature and high-pressure steam sterilization, etc.
