Wednesday, August 13, 2014: Solder paste inspection (SPI) systems measure the volume of the solder pads before the components are applied and the solder is melted. They are essential tools in PCB assembly lines, particularly in industries where tough quality and safety standards apply. It is not just the increasing board density and the miniaturisation of components that are driving this trend—the use of SPI systems in overall process control and test strategy has proved to be an unmatched return on investment, as they can reduce the incidence of solder-related defects to statistically insignificant levels.
