Abstract

In this paper, a lead-to-pad alignment technique for surface mount component placement on printed circuit boards is developed. The problem is expressed as a nonlinear optimization problem with a linear objective function and quadratic constraints. A solution procedure is developed and compared with a known nonlinear optimization solution technique. Results show substantial improvements in execution time of the optimization and yield of the placement operation when implemented in a robotic cell.
