Abstract

With the emergence of line pitch SMD technol- ogy, solder paste deposition has become a critical process parameter. The current screen print process relies on statistical process control (SPC) methods to maintain the process in its optimum range. Because of this, the process depends on a static oper- ating condition to generate its output. Thus the sys- tem output is directly tied to the calibration of the equipment.
