Single Layer Adhesive Flexible PCB Built on Polyimide With Immersion Gold for Instrument Panel

Unveiling the Versatility of Transparent Flexible PCBs

Introduction:
Embarking on a revolutionary journey, transparent flexible PCBs have become a game-changer in various industries, including consumer electronics, automotive, and medical devices. This article delves into the specifics of a remarkable single-sided adhesive transparent flexible copper clad laminate, shedding light on its exceptional properties, construction details, and wide-ranging applications.

Properties and Specifications:
With its remarkable visible light transmittance of 90.1% to 90.5%, the single-sided adhesive transparent flexible copper clad laminate takes center stage, offering unparalleled transparency and minimal light interference. Its electrical performance is equally impressive, boasting a volume  resistivity of 1.3×10^8 MΩ-cm and a surface resistance of 4.7×10^5 MΩ, ensuring rock-solid reliability.

This transparent flexible PCB excels in bonding strength and dimensional stability, guaranteeing longevity and durability. Its outstanding chemical resistance protects against corrosive substances, while its compliance with the EU RoHS directive ensures it remains free from harmful elements like Pb, Hg, Cd, Cr6+, PBB, and PBDE, making it a safe and eco-friendly choice.

Construction Details:
The construction of this transparent flexible PCB revolves around a single-layer stackup, comprising an 18 μm copper layer and a 0.05 mm polyester core (SF490). Its sleek design, with a finished board thickness of 0.06 mm, offers a lightweight and slim profile, perfect for diverse applications. The outer layers boast a finished copper weight of 0.5 oz (0.7 mils), ensuring optimal conductivity.

When it comes to surface finish, this transparent flexible PCB embraces immersion gold, providing superior solderability and resilience against corrosion. The top silkscreen, in a pristine white hue, facilitates clear component labeling, while the bottom silkscreen is deliberately omitted. Coverlay is employed for both top and bottom solder masks, delivering reliable protection against solder bridging and environmental factors.

Applications:
The application scope of the transparent flexible PCB is extensive, with a notable highlight being its exceptional suitability for large touch panels. Its transparency, flexibility, and electrical properties merge seamlessly to create touch-sensitive interfaces characterized by flawless integration and precise functionality. Its adaptability to a wide temperature range, from -40℃ to +85℃, guarantees consistent performance across diverse operating conditions.

Conclusion:
The single-sided adhesive transparent flexible copper clad laminate emerges as an unrivaled solution for countless applications, catering to the demands of various industries. Its remarkable properties, including exceptional transparency, reliable electrical performance, and chemical resistance, position it as the go-to choice for demanding applications. Whether in large touch panels or other cutting-edge devices, this transparent flexible PCB stands strong, providing a robust and efficient solution.
