Abstract

PURPOSE:To raise the inspection accuracy by detecting a solder short circuit by allowing a laser beam to pass through successively to not only the center between parts leads, but also both its sides. CONSTITUTION:It is decided to be a bridge or not by allowing a laser beam 6 to pass through the center between parts leads 4. When it is decided to be bridge by the center between the leads 4, it is inspected to be a bridge by allowing the laser beam 6 to pass through successively to both its sides in parallel and at an equal interval in accordance with sequence shown in the figure. In such a way, the inspection accuracy can be raised.
