Industrial Robots Accuracy Optimization in the Area of Structuring and Metallization of Three Dimensional Molded Interconnect Devices

Abstract

Based on their beneficial features, there is a growing importance of 3D molded interconnect devices. An important process in course of their manufacturing is the conducting pattern generation. Therefore industrial robots can be used, moving the substrate with a high accuracy relative to a process nozzle. Due to complex conducting patterns an offline programming of the robots trajectory is needed. Given to the robot, this leads to a precision of the movement not meeting the product demands. To overcome this problem, the usage of modern sensor systems for process monitoring and real-time robot control is investigated. By supervising the conducting pattern generation the actual robots position is derived. Subsequently correction values are determined and given to the robot control position deviations are compensated. For this way of proceeding an efficient methodology for data processing and correction value determination is developed. First experiments already show good results with high geometric accuracies.
