Abstract

In this paper, we developed a new mounting head system for a microchip such as flip chip. The proposed head system consists of a macro/micro positioning actuator for stable force control. The macro actuator provide the system with a gross motion while the micro device yields fine tuned motion to reduce the harmful impact force that occurs between very small sized electronic parts and the surface of a PCB(printed circuit board). In order to show the effectiveness of the proposed macro/micro mounting system, we compared the proposed system with the conventional mounting head equipped with a macro actuator only. A series of experiments were executed under the mounting conditions such as various access velocities and PCB stiffness. As a result of this study, a satisfactory voice coil actuator as the micro actuator has been developed , and its performance meet well the specifications desired for the design of the microchip mounting head system and show good correspondence between theoretical analysis and experimental results.
