Abstract
A system and method for laser marking integrated circuit packages is provided. The integrated circuit packages to be marked are positioned within trays. The trays have pockets into which the integrated circuit packages fit. If an integrated circuit package is not properly positioned within a tray pocket, it will stick up. This condition is detected by an electric eye. In a method of the invention, trays loaded with integrated circuit packages are placed on a conveyor. The trays are conveyed under an electric eye the beam of which is broken if, but only if, an integrated circuit package is improperly positioned within a tray pocket. If the beam is broken, a controller stops the conveyor, permitting an operator to deal with the problem. If the beam is not broken, the conveyor takes the tray onward to a laser marking area where all the integrated circuit packages within the tray can be consistently marked.
