Abstract
A system for controlling a boundary of spreading liquid adhesive on a surface is disclosed. The system includes one or more ultra-violet (UV) sources configurable to emit UV light onto the liquid adhesive; and a control circuit coupled to the one or more UV sources and configured to control the one or more UV sources to selectively apply the UV light at selected locations on the liquid adhesive to cure the adhesive and prevent its further spread at those locations.
