Offset Placement After Solder Screen (OPASS) printing addresses solder paste alignment errors. With the technology, the placement machine reportedly can automatically detect and compensate for misalignment of the solder paste to produce high-quality boards regardless of prior process errors. Addresses placing small components centered on the paste and not the pad, which reduces defect rate. Said to eliminate the need for other equipment such as AOI machines.
