본 고안은 반도체패키지용 리드프레임 히터블록구조에 관한 것으로서, 더욱더 상세하게는 와이어본딩된 리드프레임 자재를 패키지몰딩이 이루어지기 전에 히터블록에 안치시켜 소정온도를 예열시키어 줄수 있는 반도체패키지용 리드프레임 히터블록구조에 관한 것이다.The present invention relates to a lead frame heater block structure for a semiconductor package, and more particularly, a lead frame heater for a semiconductor package that can preheat a predetermined temperature by placing a wire bonded lead frame material in a heater block before package molding is performed. It is about a block structure.

일반적으로 히터블록은 반도체칩이 구비된 리드프레임자재를 와이어본딩한 후 회로적 성질을 보호하기 위하여 몰드금형에서 컴파운드재로 패키지 몰딩하는데 있어 몰딩공정전에 히팅장치가 구비된 히터블록에 소정시간 안치시켜 리드프레임자재에 예열시키도록 하는 것으로서, 종래에는 도시된 도면 제5도와 제6도에 도시된 바와같이 히터블록(10)의 평탄부(19) 좌우측 상부면으로 다수개의 돌기부(35)를 전후방향에 분리 형성되고, 상기 돌기부(35)가 구비된 평탄부(19)에는 좌우 길이방향으로 다수개의 요홈(30)을 형성하며, 평탄부(19)의 소정위치 전후로는 복수개의 홈(33)을 형성하고, 이홈(33)의 좌우양측 전후에 돌기부(35A)를 각각 형성하여 된 것이다.In general, a heater block is packaged from a mold mold to a compound material in order to protect the circuit properties after wire-bonding a lead frame material equipped with a semiconductor chip, and placed in a heater block equipped with a heating device for a predetermined time before the molding process. In order to preheat the lead frame material, as shown in FIG. 5 and FIG. 6, a plurality of protrusions 35 are moved to the front and rear directions on the upper and lower left and right sides of the flat part 19 of the heater block 10. A plurality of grooves 30 are formed in the flat part 19 provided with the protrusion part 35 in the left and right directions, and the plurality of grooves 33 are formed before and after the predetermined position of the flat part 19. And the projections 35A are formed at the front, rear, front, and rear sides of the groove 33, respectively.

이러한 종래의 히터블록(10)은 와이어본딩된 리드프레임자재(90)를 안치시켜 이동시킬 수 있는 픽스쳐(70)를 히터블록(10)의 돌기(35)(35A) 외부에 안치시킨 후 로더이송장치로 이송되는 리드프레임자재(90)를 픽스텨(70)에 놓여지게 함에 따라 와이어본딩 되어진 리드프레임자재(90)를 패키지몰딩이 이루어지기 전에 히터블록(10)에 안치시키어 소정온도(약 170℃)로 예열을 시키어 줄 수 있는 것이다.The conventional heater block 10 is a loader transported after placing the fixture 70 that can be moved by placing the wire-bonded lead frame material 90 outside the protrusions 35 (35A) of the heater block 10 As the lead frame material 90 transferred to the device is placed on the fixture 70, the wire-bonded lead frame material 90 is placed in the heater block 10 before the package molding is performed, and a predetermined temperature (about 170 It can be preheated at ℃).

그러나 이러한 종래 반도체패키지용 리드프레임 히터블록구조는 상기 히터블록(10)의 픽스쳐(70)와 평탄부(19)에 안치되어지는 리드프레임자재의 반도체칩이 위치하도록 형성되어진 요홈(30)과 돌기부(35)들에 의한 위치 제한성을 받게 되어 히터블록의 제작이 곤란하고, 상기 요홈(30)과 돌기부(35)(35A)들을 히터블록(10)의 평탄부(19)에 형성시키어 주어야 하므로, 제작이 곤란하게 됨은 물론 제작원가가 상승하게 되는등의 문제점이 있었던 것이다.However, such a conventional lead package heater block structure for a semiconductor package has a recess 30 and a protrusion formed so that the semiconductor chip of lead frame material is placed on the fixture 70 and the flat portion 19 of the heater block 10. Since it is difficult to manufacture the heater block due to the positional restriction by the 35, the grooves 30 and the protrusions 35 and 35A should be formed in the flat portion 19 of the heater block 10, The production was difficult, of course, there was a problem such as a rise in manufacturing costs.

본 고안의 목적은 상기와 같은 종래의 문제점을 해결하기 위해 히터블록의 상부 평탄부에 일체화된 다수개의 돌출부와 이 돌출부에 각각 소수의 요홈부만을 형성하여 상기 히터블록에 안치 고정되어진 픽스쳐의 핀에 리드프레임자재(90)가 용이하게 안치되어질 수 있는 반도체패키지용 리드레임 히터블록구조를 제공하는데 있다.An object of the present invention is to solve the conventional problems as described above to form a plurality of protrusions integral to the upper flat portion of the heater block and only a few grooves in each of the protrusions to the pin of the fixture fixed to the heater block A lead frame heater block structure for a semiconductor package in which the lead frame material 90 can be easily placed is provided.
