Dual-Frequency Card Inlay (Combi Prelam) Types
1Dual-frequency inlay specifications
Chip pairings: HF 13.56MHz + LF 125KHz; HF 13.56MHz + UHF 915MHz; HF ISO 14443 + ISO 15693; tri-frequency LF + HF + UHF. Substrate PVC. Layouts 5-5 or 3-8 (custom available). Thickness 0.50-0.02 mm. Each frequency keeps its own compliant chip and antenna, positioned to avoid coupling.
2Design and sampling
Because two antennas share one card body, the layout is planned so the fields do not detune each other. Combi builds are often lower volume, so we start from small batches and recommend testing a sample with your exact chip combination before the full run. Share both chip models and your reader systems and we will lay out the antennas accordingly.
3How two antennas share one card body
A dual-frequency inlay is not two inlays stacked. Each chip keeps its own compliant antenna, and the two are positioned so their fields do not detune each other — an LF coil sitting on top of an HF loop will pull both off resonance.
The spacing depends on the pairing. LF + HF behaves differently from HF + UHF, and a tri-frequency build needs all three planned together. That is design work, which is why we ask for both chip models and your reader types before laying it out.
4From PVC sheet to tested prelam — six stages
Dual-frequency sheets run the same six stages, with an extra placement and an extra test pass for the second chip.
5Both frequencies are tested on every unit
A combi card that works at one frequency and not the other is a scrapped card, so each frequency gets its own 100% read check — not a sample.
| What is checked | Instrument | Coverage |
|---|---|---|
| Chip response and read/write | Multi-chip test platform with reader and terminal | 100% of units |
| Antenna resonance frequency | Bode 100 vector network analyser | Setup + in-process |
| Inlay thickness | Digital height gauge | Per sheet lot |
| Chip-to-antenna bond strength | Push-force instrument | Per shift |
| Bond joint condition | Stereo microscope | Per shift |
| Substrate identity and density | Precision density balance | Incoming material (IQC) |
| Ageing and lamination survival | Constant temperature and humidity chamber | Qualification + periodic |
Combi volumes are usually lower than single-frequency, so we can start from a few hundred pieces. Test a sample with your exact chip combination and your own readers before the full run — interference problems show up on real hardware, not on paper.
