What Is RFID and Benefits of RFID in PCB Industry ?

Radio-frequency identification (RFID) technology has emerged as a game-changer in various industries, including the printed circuit board (PCB) manufacturing industry. RFID technology utilizes radio waves to communicate information between RFID tags and readers, allowing for real-time tracking of a wide range of objects, including PCB components and finished products.

The incorporation of RFID technology in the PCB industry offers manufacturers numerous benefits, including streamlining inventory management, facilitating higher product quality control, improving traceability, and boosting production efficiency. Additionally, RFID technology can provide greater visibility into the supply chain, enabling manufacturers to detect bottlenecks and other inefficiencies and optimize operations accordingly.

Innovations in RFID technology continue to emerge, promising even more advancements and benefits for businesses that use this technology. Specifically within the PCB industry, RFID technology is poised to play an increasingly critical role in shaping the future of the industry. By incorporating RFID technology into their operations, PCB manufacturers can gain a competitive edge and remain at the forefront of innovation in this ever-evolving marketplace.

What Is Radio Frequency Identification(RFID) ?

Radio Frequency Identification (RFID) is a wireless communication method that utilizes electromagnetic or electrostatic coupling in the radio frequency range of the electromagnetic spectrum. This process uniquely identifies an item, animal, or person and has the capability to track their location. Essentially, RFID search, identifies, tracks, and communicates with objects and individuals via radio frequency transmissions.

RFID is a technology that retrieves data using digital encoding from an RFID tag, and this information can be read using a reader. During this process, the device functions as a tag or label that is readable by a reader. Unlike traditional barcodes and QR codes, RFID functions by transmitting information wirelessly and through the internet. RFID can be applied using either passive or active methods and provides the ability to read from a concealed location. The collected data is then stored in a database for later retrieval.

Radio-Frequency Identification (RFID): Types

There are two types of such tags:

Active RFID

The apparatus comprises radio frequency identification (RFID) tags that are powered by a connected power supply for transmitting a signal. Concurrently, the apparatus also incorporates an antenna to facilitate the reception of data.

In the case of an active tag, it employs a dedicated power source such as a battery to enable autonomous operation without requiring energy from the source or reader. Therefore, the active tag’s circuitry can operate continuously without the dependence on external power supply, manifesting a self-dependence on its own specialized power source.

Passive RFID

Passive RFID tags, unlike their active counterparts, are not designed with an independent power supply and instead rely on power from the reader. The RFID tags integrated within this apparatus do not have a direct connection to a power supply, and passive RF tags store their energy and utilize it when exposed to emitted power from active antennas and RF tags. Such power is transmitted over specific frequencies as per standards, with low frequency utilizing the 125-134 MHZ range, high frequency employing the 13.56 MHZ range, and ultra-high frequency using the 856 MHZ to 960 MHZ range.

Unlike barcodes, RFID tags do not require direct line-of-sight with the reader and thus can be embedded into the item under surveillance. This enables Automatic Identification and Data Capture (AIDC) through the use of RFID technology.

How Does RFID Work ?

Automatic Identification and Data Capture (AIDC) encapsulates several technologies, which includes radio frequency identification (RFID). AIDC techniques, utilizing radio waves, automate the identification of items, extract data, and seamlessly feed the collected information into computer systems with minimal or no human intervention. The primary components of an RFID system are an RFID tag (smart label), an RFID reader (interrogator), and an antenna.

An RFID tag features an integrated circuit and an antenna that facilitate the transmission of data to the RFID reader. Upon capture, the radio waves are converted to an easy-to-use data format by the reader. The data accumulated by the tags is accessed via a communications interface and transmitted to the host computer system. Here, it gets stored in a database for future retrieval and analysis.

Versatility: RFID technology can be employed in a variety of applications across a range of industries, from inventory and asset management to logistics and healthcare.

Disadvantages of RFID

Radio Frequency Identification (RFID) technology has a few potential disadvantages, including:

High initial investment: Implementing an RFID system requires significant investment in hardware, software, and infrastructure such as readers, antennas, and middleware. These costs can be prohibitively high for some businesses, especially small to medium-sized enterprises.

Limited reading capabilities: Although RFID has a longer range than other automatic identification technologies, it still has limitations in reading range and may struggle with metal or liquid products or products with a high water content.

Privacy concerns: RFID raises concerns around personal privacy and data protection, as tagging of consumer goods or tracking of individuals can lead to concerns about the misuse of personal information.

Interference with other systems: RFID operates on radio frequencies, which can potentially interfere with other electronic systems in the vicinity. This could lead to system failure or malfunction, especially in sensitive environments such as hospitals or aircraft.

Standardization: Lack of standardized protocols can be a barrier to the implementation of RFID solutions, especially in global supply chains where teams need to integrate data from multiple sources into a single system.


Application of Radio Frequency Identification (RFID)

RFID tags have proven to be versatile tools, finding their way into a wide array of business sectors. In the automotive industry, RFID tags attached to vehicles during production enable performance monitoring along assembly lines, while the tracking of RFID-tagged medications as they move through warehouses ensures efficient inventory management. Microchipping pets and livestock also facilitates identification. Furthermore, retailers take advantage of these tags to speed up checkout processes, bolster security, and discourage theft by customers and employees.

Given their ability to track valuable assets, commodities, and living creatures, RFID tags give rise to legitimate concerns regarding privacy and data protection. In response to these apprehensions, standard specifications have been created to address security and privacy issues.

To avoid traceability, reader and tag authentication, and over-the-air privacy concerns, on-chip cryptography is utilized in the ISO/IEC 18000 and ISO/IEC 29167 standards. These standards also address digital signatures for use with RFID and barcodes to ensure the data’s legitimacy, its source, and its read method. This work is carried out within the ISO/IEC JTC 1/SC 31 Automatic identification and data capture techniques working group.

In the electronics industry, UHF RFID label tags are attached to finished products after the assembly process. A new approach enables the direct integration of PCB RFID label tags at earlier production stages.

Implementing PCB RFID tags provides detailed tracking information to management, allowing for precise identification of specific printed circuit boards and facilitating efficient inventory tracking and identification of production bottlenecks.
