RELIABILITY-BASED OPTIMAL DESIGN METHOD FOR A E-PRINTED PATTERN IN A R2R PROCESS

摘要

PURPOSE: An optimal design method based on the reliability of a conductive pattern is provided to utilize a mathematical model as an analysis process of a strain generation element by including a mathematical model within a logic for determining an optimal solution. CONSTITUTION: The length and the width of a printing pattern is set up in an R2R(Roll to Roll) method(S210). The stress applied to the pattern is minimized by setting up a first formula as an object function. The stress is defined to be applied to the pattern. A critical stress value which generates cracking on the pattern is calculated through a second equation.
