Abstract

Inkjet technology has made large inroads into the industrial domain. In fact, inkjet has become a mature technology for graphical applications even in functional printing like printed electronics. It is by propel the droplets of ink onto paper, plastic or other substrates. The alphabet can be print out on the printed circuit board with several of scales. But the problem is, the previous method to evaluate the quality of alphabet only measured qualitatively which not effective. For example, aspect of following the required scale. The main purpose of this project is an effort to investigate the quality of readability of alphabet on the printed circuit board by quantitatively with numerical data. Thus, this project will help to alternate the previous method to more obvious and helpful method that can justify the quality of the product. It can be seen by numerical representing the average, standard deviation and pattern of graph to prove the acceptability of quality towards alphabet on printed circuit board. It can be compare and prove by actual data. The data that includes height and width of the alphabet is studied under microscope and Measure-X software. For further studies, more alphabets are inspected and SEM analysis is done. From this study, it will help the production industries that want to look through of the readability and quality of alphabet on printed circuit board. The standard deviation of straight alphabets is smaller than curvy alphabets
