Claim:
A dicing assembly for singulating packaged devices from strips, carriers or substrate of various types, said dicing assembly comprising: a sawing device including a spindle that rotates relative to a spindle housing and a plurality of cutting blades that are separated by spacers and affixed to the rotating spindle, the rotating cutting blades being configured to cut through strips, carriers or substrates in order to obtain packaged devices therefrom; a nozzle assembly including, a pipe member in fluid communication with a fluid source; a nozzle member configured to direct fluid from the pipe member across the cutting blades, the nozzle assembly including a plurality of integral nozzles that are ganged together to form a single unit, the number of nozzles and spacing of the nozzles coinciding with the rotating cutting blades, the nozzles being in fluid communication with the pipe member and extending away from a side of the pipe member, the nozzles each including a through hole and an elongated substantially U-shaped channel having first and second open ends, the through hole starting at the pipe member and opening into the first open end of the elongated substantially U-shaped channel, the elongated substantially U-shaped channel having walls that surround a segment of the rotating cutting blades at the leading edge and at portions of both sides of the rotating cutting blade when the cutting blade is disposed within the channel, the through hole being disposed in front of the leading edge of the cuffing blade when the cutting blade is disposed within the channel, wherein during operation, the cutting blades are rotated, and fluid is directed through the pipe member and into the channels of the nozzles such that the fluid is forced along both the leading edge and a portion of the sides of the rotating cutting blades thereby cooling, cleaning and lubricating the cutting blades.
