Abstract:
An electronic device may have printed circuits to which electrical components are mounted. The printed circuits may have metal traces that form signal lines and contact pads. Vias or other conductive structures may he used in interconnecting the signal lines to the contact pads. The contact pads may have elongated shapes or other shapes and may he formed in arrays on the printed circuits. Laser welds or other electrical connections may be used to join contact pads on a first printed circuit to respective contact pads on a second printed circuit. The laser welds may form part of a rectangular region of welds or may form part of a non-rectangular region of welds such as a region with a curved edge. Alignment marks may be used in aligning the contact pads.

Abstract:
Fiducials having substantially continuous portions made on a substrate allow the position of the substrate to be determined. An approach for making fiducials involves moving first and second fiducial devices together back and forth across the substrate along a trajectory having a component along the lateral axis of the substrate while the substrate and the first and second fiducial devices are in relative motion along the longitudinal axis of the substrate. The first fiducial device operates to make one fiducial on the substrate during the movement along the trajectory and the relative motion. The second fiducial device operates to make another fiducial on the substrate during the movement along the trajectory and the relative motion. The fiducials may be formed so that they have a constant spatial frequency with the first fiducial being out of phase with respect to the second fiducial.
