Abstract

The technology of laser direct selective metallization on aluminum nitride substrate was investigated for manufacturing fine line circuits. In laser direct structuring, laser activation and electroless copper plating were used. The feasibility was evaluated by analyzing the sieving, contrast, and fine linewidth patterns, and the results showed that the width of the feasible fine reached 100 μm. A near-field communication (NFC) antenna circuit of the width of 400 μm was fabricated on the aluminum...

Abstract

Laser direct structuring (LDS) technology used for polyimide (PI) films containing copper dichromate as the activator for antenna circuits was evaluated. The polyamic solutions containing various contents (1 to 10 phr) of copper dichromate were spread on a glass sheet. Then, the solvent was evaporated and imidated to obtain the PI films containing LDS activator. The near-infrared laser was used to scan the sieving and contrast patterns of the LDS PI films, and then the electrochemical copper was...

Abstract

This study aims to create a composite supercapacitor prepared by using carbon electrodes blended with wood-derived activated carbon and monolayer graphene. The supercapacitor was integrated into dye-sensitized solar cells (DSSCs) to form a comprehensive energy system. Such a system combines the functions of solar energy conversion and storage of solar power supply systems and wearable electronic devices. In this study, the impact of gel electrolytes was investigated on the performance and long-t...
