Overview
Industrial FPC — RFID, IoT, factory automation.
Industrial electronics cover a wide substrate envelope: RFID inlays and tags for asset tracking, thin embedded sensors for process instrumentation, flex interconnects for factory-automation equipment, and compact modules for industrial IoT. CircuFlex supports the full range with fine-feature capability for RFID antennas, thin constructions for embedded sensors, and documentation discipline for industrial qualification.
- Fine antenna geometry for UHF, HF, and NFC RFID inlays
- Thin constructions (0.065 mm) for embedded sensors and flexible tags
- 600 × 500 mm panel capability for high-volume RFID production
- Documentation discipline aligned to industrial qualification expectations
- Polyimide base for industrial thermal and chemical envelopes
- Full FPC process flow for RFID, sensors, and module interconnects
- Surface finishes matched to industrial solderability and corrosion requirements
Industrial & RFID capability
From antenna to assembly, single process flow.
Industrial FPC programs benefit from one coordinated manufacturing flow — RFID antenna fabrication, thin-film electronics, module interconnects, and validation all under a single process discipline.
FEATURE 01
UHF / HF / NFC RFID
Fine conductor geometry supports the antenna designs across UHF, HF, and NFC frequency bands. From high-volume consumer tags to compact embedded industrial RFID.
FEATURE 02
Thin FPC for embedded sensors
0.065 mm board thickness and thin-film construction options let sensors embed into harsh environments — pipe monitoring, equipment condition, factory IoT.
FEATURE 03
Large-panel RFID production
600 × 500 mm maximum panel size supports high-volume RFID inlay panelisation for cost-efficient production runs.
FEATURE 04
Industrial qualification support
Audit file, control plan, FAI, and reliability test coordination — the documentation package industrial SQE teams expect.
FEATURE 05
Polyimide durability
PI base film proven in industrial-environment applications — thermal stability, chemical resistance, and long service life.
FEATURE 06
Single-flow manufacturing
DFM through electrical test in one coordinated process — reduces supplier handoffs and improves root-cause response time on industrial programs.
