Few supply chains are as long and as sensitive as that of the semiconductor industry. A chip may be designed in one country, manufactured in another, encapsulated in a third, and mounted on a circuit board thousands of kilometres from where it was first created. Every link in the chain adds value, but also risk: losses, misidentification, counterfeit components and audits that require knowing what happened to each batch.
This is precisely the area where RFID (Radio Frequency Identification) comes into its own. And that is why this November we will be where the European chip industry gathers: at SEMICON Europe 2026 (Munich, 10–13 November), at stand C2119, as part of the delegation of Catalan companies coordinated by ACCIÓ, the Catalan Government’s agency for business competitiveness.
In this article, we explain what an RFID tag manufacturer is doing at a semiconductor trade fair, where RFID adds value in this sector, and what you can expect to see at our stand.
What is SEMICON Europe?
SEMICON Europe is the leading European trade fair for the semiconductor industry, organised by the SEMI association. The 2026 edition will take place from 10 to 13 November at Messe München (Munich, Germany), alongside electronica, Europe’s largest trade fair for electronic components and systems. Together, they form Europe’s largest electronics platform.
The event brings together the entire microelectronics value chain: equipment and materials manufacturers, foundries, testing and packaging companies, automation suppliers and, increasingly, traceability and identification firms. The fact that it coincides with electronica means that manufacturers of circuit boards and equipment that use these chips are also present in the same halls. For us, the two audiences form a single conversation: identifying the product from the wafer right through to the finished device.
What is an RFID tag manufacturer doing at a chip trade fair?
The short answer: the semiconductor industry is one of the most traceability-intensive sectors in the world, and much of that traceability is achieved through RFID.
The long answer has three reasons.
1. Europe is rebuilding its manufacturing capacity. The European Chips Act sets the target for Europe to account for 20 per cent of global semiconductor production by 2030. More factories in Europe mean greater material flows, more inter-plant logistics and a greater need for robust identification systems from day one.
2. Component counterfeiting is a real problem. Counterfeit or re-labelled electronic components enter the supply chain via distribution channels. A UHF RFID tag offers something that a printed label cannot: the TID, a unique serial number encoded by the RFID chip manufacturer that cannot be rewritten, and which allows verification that the packaging arriving is the same as that which left the factory.
3. The cleanroom has been using RFID for years. The containers that transport wafers within a fab (FOUPs, SMIF pods, reticle pods) are identified using RFID systems integrated into the equipment itself, to the extent that SEMI maintains a specific standard for this purpose, SEMI E144, which defines the radio interface between the carrier tags and the readers on the production equipment. The sector doesn’t need to be told what RFID is: it uses it every day. The interesting question is another: what happens when the product leaves the cleanroom?
Where RFID comes into play in the semiconductor lifecycle
Inside the cleanroom: the carriers
At the front-end, wafers are transported in sealed containers (FOUPs for 300 mm wafers, SMIF pods, and lithography mask pods) which the automation systems identify at each piece of equipment. This layer is usually managed using readers and transponders factory-integrated into the carriers and load ports themselves, in accordance with standards such as SEMI E144. Let’s be honest: there’s little for a label manufacturer to contribute here. Our work begins when the material passes through the door.
From the back-end to distribution: where UHF reigns supreme
Between the fab, the test and packaging plant, and the end customer, there is a constant flow of wafer boxes, trays, tubes, magazines and, above all, reels (the tape-and-reel component reels that feed the assembly lines). Each of these carriers now carries printed tags that are read one by one, in line of sight, package by package.
With UHF RFID tags (RAIN RFID, EPC Gen2 / ISO/IEC 18000-63), this same flow is taken to a whole new level: a box containing dozens of reels is verified in seconds without being opened, the receipt is automatically reconciled against the dispatch note, and each container is identified with a unique serialised EPC. UHF backscatter does not require line-of-sight, so reading works just as well with sealed packaging.
Authenticity: the EPC + TID pairing
The EPC identifies the item and is encoded at the factory; the TID is the RFID chip’s serial number, engraved by its manufacturer and non-rewritable. The combination of the two, verified at source and checked at destination, makes it far more difficult for relabelled or cloned packaging to pass as genuine. In a sector plagued by component counterfeiting, this layer of verification is just as valuable as the scan itself.
At the electronics plant: SMT reception and PCB traceability
The other half of the story takes place in the factories that assemble these chips. There, RFID comes into play on two fronts. The first is internal logistics: component reception, storage of reels in warehouses, control of material exposed to moisture (MSL) and feeding the correct material to the SMT lines. A wrong reel in a feeder means an entire batch of defective boards.
The second front is the board itself. Tagging a PCB with RFID requires an understanding of the process: the tag may pass through reflow ovens, where lead-free profiles reach peaks of around 260 °C (IPC/JEDEC J-STD-020), on a substrate packed with copper and metallic components that cause any conventional UHF antenna to go out of tune. This is a clear case of ‘the tag matters’: materials and antenna designs specifically tailored to this combination of temperature, metal and minimal space are required.
Assets, tooling and cleanroom clothing
And then there is everything else involved in production: returnable containers that travel between plants, jigs, calibrated tools, measuring equipment and even cleanroom clothing, which is managed using RFID laundry tags capable of withstanding washing and sterilisation cycles. These applications are less high-profile than product traceability, but they deliver quick returns: an asset that can be located is not purchased twice.
RFID applications in the semiconductor and electronics sector
| Application | Problem it solves | How RFID solves it |
|---|---|---|
| Dispatch and receipt of batches | Manual verification, package by package, with line of sight | Bulk UHF scanning of sealed boxes and automatic reconciliation against the delivery note |
| SMT reel management | Material errors on production lines and searching for reels in the warehouse | Unique identification per reel, location by scan and control of material exposed to moisture |
| Component authenticity | Counterfeit or re-labelled components in the supply chain | EPC + TID verification at source and destination; the TID cannot be rewritten |
| PCB traceability | Identify each board throughout the process and in after-sales service | Labels suitable for reflow, metal and confined spaces, read automatically on the production line |
| Returnable assets and containers | Loss of tools, trays and containers between plants | On-metal labels on assets and readings at checkpoints |
| Cleanroom clothing and equipment | Monitoring of wash cycles and equipment allocation per operator | Laundry tags that withstand industrial washing and sterilisation |
The technical challenges: why labels matter more here than anywhere else
It is worth pausing to consider why. A metallic surface does not simply ‘interfere’ with RFID in a vague way: it modifies the electromagnetic behaviour of the UHF antenna, alters its impedance and detunes the tag, so that a conventional label stuck onto a chassis, a rack or a reel with a metallised laminate, can go from being readable at several metres to being unreadable altogether. The solution is not to increase the reader’s power, but to use RFID tags designed for metal surfaces, where the antenna is engineered to account for that surface, or to validate the exact tagging position where the substrate allows.
Something similar applies to temperature: it is not enough for the material to ‘withstand’ the thermal peak; it must retain its adhesion, print legibility and RF performance after several cycles. And in spaces measured in millimetres, the size of the antenna physically limits the range, so the correct question is not ‘how far can this tag be read?’ but ‘how far does this process need to read it?’. In our guide to industrial RFID, we explore these selection criteria in detail.
Practical example: component reception at an electronics plant
Situation. An SMT assembly plant that receives hundreds of boxes containing reels of components from various suppliers every week, with manual receiving: opening, scanning barcodes one by one, and placing them in the correct location.
Problem. Hours spent on manual handling during receipt, placement errors that subsequently halt production lines, and no systematic defence against components of dubious origin.
RFID implementation. UHF tagging of each reel and each box at source (supplier or consolidation centre), with serialised EPCs. RFID gateway or desktop reader at reception, readers in the reel warehouse and antennas at the line feed points. Scan events are transmitted via middleware to the ERP and MES.
Flow. Reel tagged at source → reading of the sealed box on receipt → automatic reconciliation with the dispatch note → location via reading in the warehouse → verification of the correct reel when loading the feeder.
Expected outcome. Receiving times are reduced from hours to minutes, stock placement no longer relies on manual processes, and each reel is traceable from the supplier right through to the circuit board it ended up on. We won’t promise you a specific percentage saving: it depends on volume, the starting point and the level of integration. What does change from day one, however, is the reliability of the data on which the plant operates.
Trace-ID at SEMICON Europe 2026: stand C2119
We are taking part as part of the delegation of Catalan companies coordinated by ACCIÓ, the public agency that brings together the Catalan semiconductor ecosystem: according to its own study, this comprises around 260 companies and organisations and some 4,600 jobs. The fact that an RFID label company from L’Hospitalet de Llobregat is part of this delegation says something about the current state of the sector: traceability is now considered part of the chip’s value chain, not just an add-on.
At stand C2119, we’ll be showcasing what best illustrates our work: physical samples. Labels for metals, industrial labels for demanding environments, miniature formats, laundry labels for cleanroom clothing, and examples of bespoke developments with encoding verified unit by unit at our factory in Barcelona. If your project is in the planning stage, bring us the actual item (the reel, tray or container) and we’ll look at it together with the tags in hand.
Checklist: what to define before discussing tags
If you’re coming to see us in Munich (or if you write to us beforehand), these are the variables we start with for any project in this sector:
- Item to be tagged: reel, tray, tube, box, container, PCB or asset, and what material it’s made of.
- Thermal and chemical processes: maximum temperatures, cycles, exposure to solvents or sterilisation.
- Space available for the tag and its orientation relative to the reader.
- Distance and reading point: gate, desktop, handheld reader or in-line antenna.
- Required data: identification only (EPC), authenticity verification (EPC + TID) or data in the User Memory.
- Target systems: ERP, MES or WMS that will process the scan events.
- Annual volume and who applies the labels: origin, consolidation centre or plant.
Frequently Asked Questions
What is SEMICON Europe and when is it taking place in 2026?
SEMICON Europe is the leading European trade fair for the semiconductor industry, organised by SEMI. The 2026 edition will take place from 10 to 13 November at Messe München (Munich), alongside the electronica trade fair. It brings together equipment and materials manufacturers, foundries and suppliers from across the microelectronics value chain.
Where can you find Trace-ID at SEMICON Europe 2026?
At stand C2119, within the delegation of Catalan companies coordinated by ACCIÓ. We’ll be showcasing samples of RFID tags for metals, industrial environments, cleanroom laundry and bespoke solutions, and you’re welcome to contact us in advance to arrange a meeting.
Is RFID used in semiconductor manufacturing?
Yes, it has been for years: the carriers that move wafers within the fab (FOUPs, SMIF pods, reticle pods) are identified using RFID systems integrated into the equipment, and SEMI maintains the E144 standard which defines that radio interface. Outside the cleanroom, the traceability of packaging, reels and assets is managed using UHF RFID tags.
Which RFID frequency is best suited to the logistics of electronic components?
For packaging, reels and assets, the standard practice is UHF (RAIN RFID, EPC Gen2 / ISO/IEC 18000-63), as it allows dozens of tags to be read simultaneously, without line of sight and from several metres away. Within the fab’s equipment, systems operating at other frequencies—integrated by the equipment manufacturers themselves—coexist.
Does RFID work on reels and metal-based substrates?
It works if the tag is designed for it: metal detunes a conventional UHF antenna, so on metallic or metalised surfaces, on-metal tags with an antenna adapted to that surface are used. Validation on the actual carrier is mandatory before scaling up.
Can an RFID tag pass through the reflow oven on an SMT line?
There are tags made from technical materials designed for high-temperature processes, but not every tag can withstand this: lead-free reflow profiles reach peak temperatures of around 260 °C. The tag must be validated in the actual process, checking adhesion, print quality and RF performance following the thermal cycles.
How does RFID help combat counterfeit electronic components?
By providing a layer of verification that is difficult to replicate: the serialised EPC identifies each package, and the TID is a unique serial number encoded on the RFID chip that cannot be rewritten. Checking both at the destination against the source data allows re-labelled or duplicate packages to be detected.
Can RFID be integrated with the plant’s ERP or MES?
Yes: the readers publish read events which the middleware filters and delivers to the ERP, MES or WMS, so that receipts, stock locations and consumption are updated without manual intervention. Integration is part of the project design, not a later addition.
Shall we meet in Munich?
If your company manufactures, encapsulates, distributes or assembles electronics and you’re considering RFID for traceability, authenticity or asset management, SEMICON Europe is the perfect opportunity: 10–13 November, stand C2119. Get in touch with us beforehand and we’ll book a slot with our technical team; if you’re unable to travel, we’ll analyse your requirements anyway and prepare samples for you to test on your actual equipment.
