- A
slurry 4 that has passed through a cylindrical main body is jetted from a slurry-jetting opening 5, theslurry 4 is jetted onto a resin burr attached to, for example, a base part of aterminal 20 b, and the resin burr is removed. - In the present invention, the slurry-
jetting opening 5 has a polygonal shape in cross-section, theslurry 4 jetted from the slurry-jetting opening 5 is in the shape of a rectangular prism, and processing is performed with good efficiency. - That is, when a
semiconductor package 20 undergoes wet-blast processing, it is necessary that anarea 20 a covered by a synthetic resin not be jetted by theslurry 4. Theslurry 4 is jetted along the outer edge of thearea 20 a covered by the synthetic resin, but the outer edge area of the jetted slurry is arcuate when the slurry-jetting opening 53 is circular, as illustrated inFIG. 6 , and the outer edge of thearea 20 a covered by the synthetic resin is linear, as illustrated inFIG. 7 , resulting in poor processing efficiency. - Inasmuch, because, in the present invention, the
slurry 4 is jetted in the shape of a rectangular prism from the slurry-jetting opening 5, and the outer edge area of thejetted slurry 4 is linear, the jetted surface area relative to the outer edge of thearea 20 a covered by the synthetic resin is larger than in the above-described case in which the slurry-jetting opening 5 is circular, as illustrated inFIG. 5 , and resin burrs can be removed quickly and with good processing efficiency. - Specific examples of the present invention will be described on the basis of the drawings.
- The present example is a nozzle body M for a wet-blast processing apparatus in which a
slurry 4 formed by mixing an abrasive 3 in aliquid 2 is jetted together with pressurized air, the nozzle body M removing a burr (resin burr 30) attached to aterminal 20 b of asemiconductor package 20 formed by providing a wiring substrate with an electronic component such as a semiconductor integrated circuit chip and covering thesemiconductor package 20 with a synthetic resin. - Specifically, the wet-blast processing apparatus is: provided to a
base body 21 through which thesemiconductor package 20 which is a body to be processed passes, as illustrated inFIG. 1 ; equipped with a slurry-jetting part comprising the nozzle body M, a slurry-accumulatingpart 22 installed in a lower position, and a slurry-conveyingpart 24 for conveying the slurry from the slurry-accumulatingpart 22 to the slurry-jetting part via apump device 23; and configured so that the slurry jetted from the slurry-jetting part is sent to the slurry-accumulatingpart 22 to be reused. Numeral 25A is a pressurized-air-supplying device, 25B is a pressurized-air-conveying part, and 26 is a slurry-returning/conveying part connected to the nozzle body M, the slurry-returning/conveying part returning theslurry 4 to the slurry-accumulatingpart 22. - The nozzle M is configured of a cylindrical
main body 6 and a fittingcylinder 8 continuously connected in a fitted state to the cylindricalmain body 6, as illustrated inFIG. 1 . - In addition, a base end of the cylindrical
main body 6 is continuously connected to a base end part of thefitting cylinder 8, and the base end part of the fittingcylinder 8 is continuously connected to the pressurized-air-conveyingpart 25B via aport 10. - Furthermore, a
communication hole 12 is bored into an area arranged inside aspace 7 of the fittingcylinder 8 in the cylindricalmain body 6, and aslurry introduction part 13 connected to the above-described slurry-conveyingpart 24 and aslurry output part 14 connected to the slurry-returning/conveyingpart 26 are provided to a prescribed outer peripheral location on the fittingcylinder 8. - The cylindrical
main body 6 of the present example is, as illustrated inFIGS. 1 to 4 , configured so that the periphery of a to rectangular cylindrical member 6 a provided with a cylinder hole having a square shape in cross-section and being formed of a suitable metal member is covered by a syntheticresin coating member 6 b, and a tip opening part having a rectangular shape in cross-section is configured as the slurry-jetting opening 5 for jetting theslurry 4 at the tip of the cylinder hole of the rectangular cylindrical member 6 a. - Accordingly, the
slurry 4 is jetted in the shape of a rectangular prism from the slurry-jetting opening 5. - In addition, in the present example, the opening dimensions of the slurry-
jetting opening 5 are set to a length of about 6 mm and a width of about 3 mm. The slurry-jetting opening 5 may have a square shape in cross-section (for example, length of 3 mm, width of 3 mm). - Furthermore, although not illustrated in the drawings, when a guide extending from the slurry-jetting opening 5 toward the tip (downward) in the slurry-
jetting opening 5 is provided, dispersing of theslurry 4 to the outside (periphery) is inhibited, and satisfactory burr removal can be performed without as much of a tendency for the jettedslurry 4 to degrade. - Because of the above-mentioned configuration of the present example, the
slurry 4 can be introduced to the inside of thespace 7 from theslurry introduction part 13, and theslurry 4 can be outputted from theslurry output part 14 to the outside of thespace 7. As a result, the pressure of theslurry 4 is reduced by the outputting of theslurry 4 from theslurry output part 14, and theslurry 4 is circulated while a constant pressure is maintained inside thespace 7. In this state, when pressurized air is introduced into the cylindricalmain body 6 from theport 10, the pressurized air draws theslurry 4 into thespace 7 via thecommunication hole 12, and theslurry 4 is accelerated by the pressurized air inside the cylindricalmain body 6 and jetted in the shape of a rectangular prism to the outside from the slurry-jetting opening 5. Theslurry 4 is circulated inside thespace 7 by theslurry introduction part 13 and theslurry output part 14, and a constant pressure is maintained inside the space 7 (accordingly, even if theslurry 4 is drawn into the cylindricalmain body 6 via thecommunication hole 12, the pressure inside thespace 7 does not change.). - According to the present example, the
slurry 4 is therefore jetted from the slurry-jetting opening 5 in the shape of a rectangular prism, and the outer edge area of thejetted slurry 4 is linear. Therefore, the impacted surface area of the outer edge of the semiconductor package 20 (thearea 20 a covered by the synthetic resin) is larger than a case in which the slurry-jetting opening 5 is circular, as illustrated inFIG. 5 , andresin burrs 30 can be removed quickly and with good processing efficiency. - In addition, the present example is configured so that the
slurry 4 is drawn in by pressurized air passing through at a constant pressure from thespace 7 in which theslurry 4 is enclosed at a constant pressure, and there is no excess abrasive. Furthermore, the air-intake pressure for taking in air through thecommunication hole 12 is maintained at a good balance, the jettedslurry 4 is therefore not intermittent, jetting can be performed smoothly and continuously, and the amount of the abrasive in theslurry 4 jetted from the slurry-jetting opening 5 is constant because the amount of the abrasive drawn in from thecommunication hole 12 is constant. - Accordingly, the power for drawing the
slurry 4 into the cylindricalmain body 6 via thecommunication hole 12 is appropriately adjusted by adjustment of the air pressure, whereby the diameter of the slurry-jetting opening 5 can also be reduced as much as possible, and deburring can be performed that much more accurately in a desired area. - Furthermore, it is preferable that the diameter of the cylindrical
main body 6 be reduced in order for accurate deburring to be performed. - As a result of experimentation, jetting of the
slurry 4 can be continuously performed without intermittency. - Because the pressurized-air passage can be made longer than with the conventional art example (in the conventional art example, the pressurized-air passage is the cylindrical
main body 6, and the length of the pressurized-air passage is the length of the cylindrical main body 6), the length over which the air is accelerated is increased in commensurate fashion, and the jetting speed from the cylindricalmain body 6 can therefore be increased even if the air-supply pressure is not increased to such an extent. The effectiveness of burr removal can therefore be improved. - This means that the expansion of air in the long air passage is commensurately sufficient, and air-flow regulation is excellent. The width of pressurized water when jetted from the cylindrical main body 6 (radially expanding width) is reduced in commensurate fashion, and accurate deburring can therefore be performed in commensurate fashion on an area in which deburring is desired. In addition, reducing the width when the water is jetted from the cylindrical
main body 6 means that noise generated during commensurately spreading can be suppressed. - The present invention is not limited to the present examples, it being possible to design the specific configuration of various constituent elements as appropriate.
