The Transparent Circuit Board redefines electronic design possibilities, breaking free from the opaque limitations of traditional PCBs to blend uncompromising functionality with sleek, invisible integration. Whether powering futuristic displays, rugged automotive systems, or precision medical devices, this innovative component balances optical clarity, mechanical resilience, and electrical performance—making it a cornerstone for next-gen electronics .
Material Versatility for Every Use Case
Every Transparent Circuit Board is engineered with substrate-conductive layer combinations tailored to specific application demands:
PI-Based Transparent Circuit Board: A flexible workhorse with 84%-87% transmittance, capable of withstanding 92,000+ bends at R=3.2mm. Paired with graphene (96% transmittance, 28-98Ω/□) or silver nanowire (4-19Ω/□), it excels in wearables and foldable devices where durability meets transparency .
Tempered Glass Transparent Circuit Board: Delivers 90%-91% light transmission for high-visibility applications like HUDs and transparent displays. Its rigid structure pairs with ITO (84% transmittance, 9-48Ω/□) for stable signal integrity in fixed systems .
PET Transparent Circuit Board: Balances cost and performance with 0.09-0.19mm thickness and 2.8-3.2 dielectric constant, ideal for consumer electronics and low-profile smart home controls .

Performance That Endures
Beyond transparency, this Transparent Circuit Board delivers reliability for harsh and precision-critical environments:
Optical & Electrical Balance: Maintains transmittance ≥83% across all variants while supporting min line/space of 4.2/4.2mil—critical for compact sensors and high-density displays .
Environmental Resilience: Survives 1,000 thermal cycles from -53℃ to 286℃ without delamination. ENEPIG surface treatment (Ni 2.7-4.6μm / Pd 0.07-0.22μm / Au 0.02-0.07μm) resists corrosion, making it suitable for automotive and marine use .
Compliance You Can Trust: Meets IPC-2221 (Class 3) for precision, AEC-Q200 for automotive-grade reliability, and RoHS 3.0 for global market access .
Where Transparency Drives Innovation
The Transparent Circuit Board transforms products across industries by turning "invisible" circuitry into a design advantage:
Consumer Electronics: Powers transparent displays and flexible wearables, where its low-profile (0.08-0.19mm total thickness for PI variants) and clarity enhance aesthetic appeal .
Automotive: AEC-Q200-certified models integrate into HUD systems and LiDAR modules, combining optical clarity with vibration resistance .
Medical: Enables miniaturized endoscopes (thanks to 0.06mm-thick PI substrates) and biocompatible wearables, where visibility aids surgical precision .
New Energy: Embedded in transparent photovoltaic curtain walls, balancing 83%+ light transmission with efficient energy harvesting .
