Abstract

Due to their vast number of benefits, plenty of complex and miniaturized three dimensional molded interconnect devices are developed. One especially demanding process step during their manufacturing is the geometrical exact creation of the conductive pattern layout on the different substrates' faces. Therefore, sophisticated and flexible technologies like laser direct structuring or printing processes can be used, which are subject to multiple research activities, concentrating for example on coating materials or process parameters. An additional aspect is the necessity of providing a flexible and sufficiently accurate handling device, which three dimensionally moves the substrate relative to the process nozzle applying the coating material. For this task industrial robots could be used, which inherit multiple beneficial features. One main drawback of using this type of kinematic is their relative low absolute accuracy of a few hundred microns, which is not sufficient for moving the substrate during the process with the needed accuracy. To exploit the multiple advantages which accompany the usage of standard robots, in current research activities at FAPS institute a new approach is investigated, improving their accuracy in course of complex 3D-movements. In this work, modern optical sensor systems for online process monitoring and subsequent real-time robot control are used. By continuously supervising the conducting pattern generation progress, the actual process spot position on the substrate is determined. Subsequently, this information is used to continuously derive the robots actual position. Compared with target state values, geometrical offsets between actual state and target state are calculated. Considering this information during the process, a closed-loop control of the robot control is established and the robot's movement is corrected in real-time. Thereby, position deviations are compensated and an accurate application of the conductive pattern layout on the substrate is obtained. Improving the accuracy of conventional industrial robots and as a result qualifying them for supporting the conductive pattern generation of miniaturized 3D-MID products can greatly contribute to the MID technology. With their high flexibility of movement, the advantage of design flexibility of the 3D-MID technology can be even better exploited and hence more sophisticated 3D-MID products and applications will be possible in the future.
