This project describes the problems of securing and placing SMD electronic components on PCB cards when the conventional method is applied. SMD components may be badly welded and damaged; therefore, the PCB is of poor quality. Surface mount components should not be touched by hand, because it could generate electric shocks to the integrated circuit. The time to place the SMD components correctly in their reference position depends on the number of components and the type of packing to be placed on the PCB. This paper presents two proposals for mechanical design. The pneumatic suction module was designed in the SolidWorks program and performed stability tests with step function and position inputs to analyze the behavior of the open loop and closed loop. The first model is designed with power screws and circular guide shafts to transfer the load and DC brushless servo motors with optical encoders were selected. The second design is designed with linear guide shafts to move the load and AC servo motors with absolute encoders were selected. Mathematical modeling of the electro-pneumatic system and the servomotors with PID controllers was carried out in the MatLab / Simulink program. With the simulation of finite element analysis of the mechanical components, the resulting stresses are minimal. The design based on power screws is lower cost and slower, but the model designed in linear guide shafts is higher cost and more flexible.
