Temperature control for weld paste: a proposal for improvement in the SMT sector

Due to the great technological advance in the most varied segments of the automatic insertion sector, little is concerned with the temperature control of the weld paste that will be applied in the printed circuits (PCB), used in the most diverse equipment. Knowing that the process of applying the weld paste is one of the first steps of the sector, great attention should be paid to the quality of the weldpaste used, because the low efficiency in this step will generate great impacts for the other, as well as can impact the end customer. In order to give due importance to this stage of the manufacturing process this article shows the reality between equipment that has the control and temperature adjustment through air conditioners coupled to screen printer equipment, and those that perform the same function, however, without the control and temperature adjustment of the weld paste inside the equipment during the use and application of the same in the printed circuits. Performing a comparison between the equipment, it was observed how much an improvement not implemented for the whole plant, generated considerable impacts to the production process, which if it had been made could in addition to generate higher profits for manufactures, also generate greater confidence and customer satisfaction before the ready product produced with more quality.
