Abstract
Abstract An improved tool for use with a die bonding machine. The tool has means on one end thereof for releasably holding an elongated die in either of a pair of angularly disposed positions, including a first group of spaced, die-engaging lips between which a die extends when the die is in a first position and a second group of die-engaging lips disposed transversely of the first group of lips for positioning the die when the latter is in the second position extending transversely of the first die position on the tool. The tool has a fluid passage therethrough terminating at a location between the lips so that, when the passage is coupled to a source of vacuum, a die can be held releasably thereon in either position. The method includes picking up a first die by the tool when the die is oriented in the first position and moving it to a first disposal point, then picking up a second die oriented at an angle relative to the first die and moving the second die to a second disposal point adjacent to the first disposal point, the picking up and moving of the second die being accomplished without rotating the tool in its support.
