Application of MCDM Methodology for Performance Evaluation of Inkjet Based Micro-Fabrication Process

摘要

Recently drop on demand based direct write inkjet printing technology has been used in application areas like printed electronics,sensor fabrication in micro-nano scale.It also finds its employability in micro fluidics and drug development application as a micro scale dispensing medium.Like any other real field application problem,E-jet have several criteria or attributes and to fully realise the potential of this technology,fulfilling them is a tricky issue.This paper proposes the application of Technique for Order Preference by Similarity to Ideal Solution(TOPSIS)to come up with an alternative which could handle the multi-criteria decision-making problem for E-jet microfabrication process.The proposed methodology has done an exhaustive search among several alternatives in a chosen experimental domain,while tries to strike a trade-off between ejected droplet diameter and throughput of the process simultaneously.After conducting the analysis the favourable operational condition of the process has been identified.The proposed approach can be used as an offline quality improvement measure of the said process.
