Engineers were tasked with creating electronic circuits that have more functionality and take-up less space. Component spacing became an issue because the closer components are located to each other the harder it is to manufacture them. It is necessary to find a manufacturing process where the components will stay centered.
ASI Consulting Group used Robust Optimization techniques to test the manufacturing process and ensure that component spacing would not be an issue for failure. The optimized design reduced position variable by over 32%.
The new process design for component spacing allowed for smaller circuit boards. Smaller circuit boards are cheaper and lighter.
