Abstract
Circuit making is one of the significant gateways in implementing electronics technology. The traditional printed circuit board (PCB) is an excellent advancement on hand-wired circuit boards. By making an electric circuit, a conductive path for the flow of current is established. Notwithstanding, electronics enthusiasts still encounter difficulties in the multiplicity implementation of components. Moreover, the frail complexity of PCB designing and manufacturing can result in failure issues. The main idea of this study is the use of Ink made of charcoal which is applicable only in paper can be a conductive path. By developing the idea, the researchers used graphite and carbon black found in waste dry cell batteries containing high conductive properties and adhesive property, making the ink sticky to the desired platform. Through testing and observation, a mixture of 15ml (2×7.5ml) carbon black and graphite and 15ml of adhesive processed through EXAKT80E Machine (Mixture 2:2:0) is the most effective formula, garnering the most satisfying results among the other ratios. The acceptability rating of the proposed product was compared to the traditional one in terms of conductivity, adhesiveness, viscosity, and thermal resistivity. The Mixture 2:2:0 was tested in both direct current (DC) and alternating current (AC) applications including series and parallel circuits in prepared surfaces. Among the 5 mixtures, Mixture 2:2:0 shows a significant effective result.
