RFID Traceability for Electronic Components: a Tag Compatible with Antistatic Protection

The Client

A company active in electronics manufacturing moves a large number of sensitive components every day — boards, semiconductors, assembled modules — between internal departments, external suppliers and end customers. As is common across the sector, every component travels protected in antistatic containers: an essential precaution against electrostatic discharge (ESD), which can silently damage circuits and high-value components even without visible signs of failure.

The Challenge

The client managed the movement of these containers without a precise tracking system: the position of a batch at any given moment — still on the shop floor, already at the supplier, or in delivery to the customer — had to be reconstructed through a paper log, a phone call, or a visual check. The result was partial visibility across the internal and external supply chain, with a concrete risk of delays, shipping errors and loss of traceability on materials of high economic value and extreme physical sensitivity.

Applying an RFID tag to an antistatic container is not, however, a neutral operation the way it would be on a standard package. The tag must coexist with the electrostatic properties of the container without compromising them: the wrong material or adhesive can alter the container's charge dissipation, defeating the very purpose the container exists for. On top of this, an electronics manufacturing environment often defeats standard off-the-shelf RFID solutions, where electromagnetic interference, proximity to metal masses and specific materials cause missed or unstable reads.

The Wintag Solution

Wintag designed a tag built to be applied directly to the antistatic container, drawing on decades of experience in technical plastics processing inherited from Astraplast. The project's priority was identifying materials and a fastening system compatible with the container's antistatic requirements, avoiding any interference with its dissipative properties, while at the same time ensuring a stable RFID read even in an electronics manufacturing environment with nearby metal surfaces and possible sources of RF disturbance.

The tag was sized to follow each container throughout the entire movement cycle — from the internal department, to the supplier, through to delivery to the external customer — with no need for replacement or maintenance, and able to withstand the repeated handling typical of a high-turnover logistics cycle.

The Results

The client now has continuous traceability of the container across the entire supply chain, internal and external: they always know where each batch is, at every stage of the process, without having to manually reconstruct movements. The electrostatic protection of the components remains intact, because the tag was engineered not to alter in any way the characteristics of the container it is applied to. The benefit translates into less time spent tracking down batch locations and a reduced risk of delays or errors on high-value materials.

Technology Used

For applications of this kind, Wintag evaluates the most suitable combination between UHF RFID tags (long-range reading, ideal for department gates and mass inventory of containers in movement) and NFC/HF tags (close-range reading via smartphone, useful for manual spot checks). The choice of chip, encapsulation and fastening system is defined together with the client, taking into account the container's ESD specifications, the required reading distance and the reader infrastructure already in place or to be installed. Integration with the client's management systems takes place via standard APIs, with no need for structural changes to existing information systems.
