RFID tags, also known as transponders, are devices with a microchip and an antenna that is used to store data and communicate with readers. The microchip in an RFID tag is composed of silicon, while the antenna can be made of various materials such as etched copper, aluminum, or conductive ink. In this blog post, we will discuss the various materials that can be used to make RFID tags.
The Chip & Antenna
The chip and antenna are typically put on a substrate that is either PET or paper. This inlay is then inserted into a printable label to create an RFID transponder that can be affixed to a product. Depending on the environment where the tag is used, it may need to be embedded in hard plastic or ceramic to protect it from heat or physical damage.
For example, if the tag needs to withstand extreme temperatures or industrial environments, it may need to be embedded in ceramic or hard plastic. Some tags can be embedded in metal; these are known as armored-RFID tags and they are designed specifically for harsh conditions.
Tag Packaging
In addition to the material of the chip and antenna, another factor that must be considered when making RFID tags is their packaging. Tag packaging helps protect the tag from environmental damage such as water, dirt, dust, and other contaminants.
It also protects against physical wear and tear from use over time. Typically, tag packaging is made from synthetic materials such as vinyl or polyethylene terephthalate (PET). However, depending on the environment where the tag will be used, certain metals such as stainless steel may also be used for their protective properties.
RFID tags have been used for many different applications over the years due to their versatility; so understanding what materials they are made of is essential to ensure they perform well under any given condition.
The microchip in an RFID transponder is composed of silicon while its antenna can be made of etched copper, aluminum or conductive ink embedded on either PET or paper substrate material depending on its intended usage environment; furthermore protective packaging can range from synthetic materials like vinyl and PET up to stainless steel in more extreme cases.
