Techniques of embedding RFID in PCBs
Radio Frequency Identification (RFID) is the technology of using electromagnetic fields for the transfer of data to automatically identify and track tags attached on objects. Such tags contain some information that is electronically stored. Moreover, some RFIDtags are powered through the process of electromagnetic induction from various magnetic fields produced near the observer. Some RFIDs collect energy from the interfering radio waves and act as passive transponders. Other types of RFID have a local power source like a battery that can operate at a range hundreds of meters from the operator. RFIDs have various applications like Automatic Identification and Data Capture (AIDC) and embedding in PCBs. As experts in the PCB world, RUSHPCB is dedicated to educating you of the operation of PCBs and several factors affecting this technology.
Embedding RFIB (Radio Frequency Identification) in PCBs means that the PCB will be uniquely and easily identified since there are RFID antennas or chips which are in the PCB. However, this is carried out in the early stages of production since the chips are placed in the PCB. This technology RFID technology is crucial in military and medical applications where Printed Circuit Boards are used. Moreover, this gives supply chains and brand owners new methods to configure PCBs more easily, update them and improves the security of consumer electronics. On the other hand, surgeons and doctors can use RFID various techniques of embedding RFIDs in PCBs to reduce counterfeits and obtain significant information from patients who have undergone joint replacement surgeries with minimal risk of memory loss.
Embedding RFID in Printed Circuit Boards increases the product’s flexibility since wireless collection of data is simple compared to other methods like using optical scanning barcodes which are printed directly on the PCB. Moreover, RFID data can be updated unlike that of barcode which can’t be updated. As if that is not enough, embedding RFID in PCBs adds the capabilities for flexibility during manufacturing and the practical applications. Some of these special capabilities include the ability to update firmware and configure commercial derivatives even after the completion of manufacturing stage. Moreover, the firmware, production date and die reel numbers can all be stored on the RFID’s tag thus they can be captured wirelessly.
Embedding RFID in PCBs makes them smart electronics since their security features are built in. This is different from the previous scenario where ensuring that PCBs were sold through the authorized sales channels was hectic. RFID technology allows brand retailers and owners to authenticate the sales process and associate PCB warranty and repair records with each product. Comparatively, embedding RFID in Printed Circuit Boards improves its visibility of the boards since a manufacturer can easily track them when they are stolen using their tags. This is possible since after purchasing, the embedded chip can be changed to indicate that it has been purchased. However, if the RFID enabled PCB is passed through the RFID gate before purchasing, the reader in the gate is signaled of this and the alarm is triggered on. Equally important, unlike EAS tags, RFID tags are inaccessible to outsiders and can’t be separated from the product.
Embedded RFID in PCB identification systems act as antennas with read distances ranging to several centimeters and features like high reading accuracy, fast data acquisition and the ability to read through packaging and enclosures. Recently, Beta LAYOUT came up with the MAGIC-PCB which is an RFID PCB identification system which uses the Murata’s Magicstrap modules which is used as RFID tags. With their partners in the RFID industry, Beta LAYOUT has come up with a better tool that can enable developers to consider and try the new PCB technique for embedding RFID. On the other hand, Murata’s Magicstarp is a tiny and robust device used as an RFID tag using its built-in IC and it excellent RF functions. This is then embedded in the PCB or its surface which possess UHF (Ultra High Frequencies) bands hence shorter wavelengths. This utilizes smaller antenna designs that the HF or LF chips.
The integrated adaptive matching circuits in the multi-layer structures enable the ground planes of the PCB to be used antennas with a reading distance of several millimeters. Some other features of this RFID embedding technique in PCBs is that it possesses fast data acquisition capability of over 100 tags per second, the ability to read through enclosures and the packages, high reading accuracy and offers a variety of turnkey antenna designs. The design comes with an RFID starter kit which includes the R/W (read/write) device, a PCB, Magistrap samples and antenna modules. However, experts argue that since most of PCB components are metallic, there exists some interference between the metallic materials and the RFID systems. The level of interference depends on the size, position and the structure of the materials used.

Embedding RFID in Printed Circuit Boards can also be carried out by the Laser Enabled AdvancedPackaging (LEAP) technique which was developed by researchers in the North Dakota State University.
The LEAP technique for embedding RFID in PCB is best suited for embedding ultrathin passive RF identification chips on the PCB. This technique uses thin silicon chips which cannot be detected when embedded in a piece of paper or any other laminate. The chips and antennas are joined on the PCB substrate at a high speed using the low cost laser technology. Uniquely, this technique is crucial for maintaining the authenticity of any PCB thus preventing counterfeiting.
Embedding RFID in PCBs is a field of interest to many researchers and researchers and a lot of research is yet to be done especially to reveal the rate of interference between the PCB components and the RFID. Moreover, better-sophisticated applications of PCBs embedded with RFID especially in military and the medical world are yet to be discovered.
