Micropatterning using maskless electrochemical micromachining

Abstract

To attain economical micropatterning of microfeatures on the planar surfaces, a developed and maskless electrochemical micromachining procedure (MEMM) is applied wherein a layer of coating with unified micropores is made on the micropatterned tool. The textured tool and substrate are attached mechanically with sturdy structure in economically developed EMM cell. A distinctively electrolyte flow path by accommodating the textured tool with designed textures is manufactured in the cell unit to substantially mitigate mass removal restriction due to opening of the narrow-textured area in the tool. A single micropatterned tool creates multiple identical microtextures cost-effectively. Experimentation is carried out to appraise this anticipated MEMM procedure, with the effort on analysing the uniformity of dimensions of the machined micro impressions utilizing the influence of duty ratio and frequency. It is revealed that the advanced MEMM method displays beneficial machinability and pertinency to create micro impressions with considerably identical profiles on the planar surfaces.
