Film and panel two-dimensional relative position optimization

Marchewka A., Wocianiec R., Zdrojewski J.

Journal of Polish CIMAC

2011

Vol. 6, no 3

145-158

The article presents automatic films registration system for printed circuit board exposure units with a new proposed processing method, based on the Radon transformation. The conditions and criteria of alignment deviation evaluation for selected registration marks were defined. Proposition of a mechatronic unit built on a base images from to 2 or 4 movable cameras and 6-axis films positioning device is designed. Align film and panel for a solder mask targets images processing method, based on the Radon transformation, was used. Rules for 2- and 4-point films position optimization were created, as wells as marks and registration algorithms. Experimental results showing capability and limits of the registration system were presented.
