Summary
In this paper method, based on the Radon transformation, used to align film and panel for a solder mask targets during registration before exposure, is presented. One of the challenges for the registration system is the images quality. System stability can depend on the type of liquid (LPI) or dry film (DFSM) used as a mask, resulting in changes of the panel reflection. Proposed method will be used to supply requested parameters for the alignment process used in the dedicated exposure machine based on LED technology.
