NOZZLE BODY FOR WET-BLAST PROCESSING APPRATUS

摘要

The purpose of the present invention is to provide a nozzle body for an innovative wet-blast processing apparatus that demonstrates unprecedented effects. The present invention is a nozzle body for a wet-blast processing apparatus in which a slurry (4) formed by mixing an abrasive (3) in a liquid (2) can be jetted together with pressurized air. The nozzle body removes burrs attached to a terminal (20b) of a semiconductor package (20) formed by providing a wiring substrate with an electronic component such as a semiconductor integrated circuit chip and covering the semiconductor package (20) with a synthetic resin. The nozzle body has a slurry-jetting opening (5) for jetting the slurry (4) to the tip of a cylindrical main body (6). The slurry-jetting opening (5) is formed having a polygonal shape in cross-section.
