The FPC sheet is placed on the die, and then the semiconductor chip is transferred to the head to be seated. On the other hand, when the chip is seated on the FPC sheet, if the surface of the chip is not uniformly adhered to the top surface of the sheet, poor contact may occur between the chip and the circuit of the sheet, so that the bottom surface of the head and the top surface of the die are parallel to each other. Should be done. However, such a chip bonder is constructed by assembling a large number of mechanical parts. Therefore, when operating for a long time, the head and die may not be perfectly parallel and inclined due to play or error generated between the mechanical parts. Is generated.

따라서, 상기 칩본더 헤드는 상기 흡착기구에 흡착된 칩의 각도를 시트의 굴곡면에 맞춰 소정각도 기울이므로써, 시트에 인쇄된 회로와 칩의 사이에 접촉불량이 발생되는 것을 방지할 수 있도록 구성된다.Therefore, the chip bonder head is configured to prevent contact failure between the circuit printed on the sheet and the chip by tilting the angle of the chip adsorbed by the suction mechanism to the curved surface of the sheet. do.

따라서, 헤드블록(6)과 상부조절블록(8) 및 하부조절블록(10)을 상호 이완시킨 후, 하부조절블록(10)의 저면을 상기 다이(23)의 상면에 밀착시키면, 상부조절블록(8)과 하부조절블록(10)이 적절히 각도조절되어, 하부조절블록(10)의 저면과 다이(23)의 상면이 평행을 이루게된다. 그리고, 상기 유입실린더(34)를 신장시키면, 상기 고정바(28)가 하부조절블록(10)을 당겨, 헤드블록(6)과 상부조절블록(8) 및 하부조절블록(10)에 형성된 오목부(16,20)와 돌출부(18,22)를 상호 강제로 밀착시키므로써, 상부조절블록(8)과 하부조절블록(10)이 유동되지 않도록 고정하게 된다.Therefore, after relaxing the head block 6 and the upper control block 8 and the lower control block 10 mutually, if the bottom surface of the lower control block 10 is in close contact with the upper surface of the die 23, the upper control block (8) and the lower control block 10 is properly angled, so that the bottom of the lower control block 10 and the upper surface of the die 23 is parallel. Then, when the inlet cylinder 34 is extended, the fixing bar 28 pulls the lower control block 10, the concave formed in the head block 6, the upper control block 8 and the lower control block 10. By forcibly adhering the parts 16 and 20 and the protrusions 18 and 22 to each other, the upper control block 8 and the lower control block 10 are fixed so as not to flow.

그리고, 이와같은 과정은 매일 작업을 시작할 때, 또는 상기 다이(23)를 교체할 때 한번씩만 실시하면 된다.And, this process only needs to be performed once at the beginning of daily work or when the die 23 is replaced.

이와같이 구성된 칩본더 헤드는 전자석(14)을 이용하는 종래의 칩본더 헤드와 달리, 상기 고정바(28)와 공압실린더(34)를 이용하므로, 구조가 간단하고, 전기를 소모하지 않을 뿐 아니라, 코스트를 절감할 수 있는 장점이 있다. 특히, 고정바(28)와 공압실린더(34)는 자력이나, 전자파를 발생하지 않으므로, 자력이나 전자파에 의해, 반도체칩(4)이 손상되거나 오작동되지 않는 장점이 있다.Unlike the conventional chip bonder head which uses the electromagnet 14, the chip bonder head configured as described above uses the fixing bar 28 and the pneumatic cylinder 34, so that the structure is simple and consumes no electricity. There is an advantage to reduce. In particular, since the fixed bar 28 and the pneumatic cylinder 34 do not generate a magnetic force or an electromagnetic wave, there is an advantage that the semiconductor chip 4 is not damaged or malfunctioned by the magnetic force or the electromagnetic wave.

본 실시예의 경우, FPC에 반도체칩(4)을 안착하는 칩본더 헤드를 예시하였으나, 이러한 칩본더 헤드의 구조는 FPC이외에, 일반적인 PCB나, 반도체패키지의 리드프레임이나, 서브스트레이트에 반도체칩(4)을 안착하는 칩본더 헤드 등에도 적용할 수 있다. 또한, 상기 승강구동기구(34)는 공압실린더를 이용하였으나, 필요에 따라, 유압실린더와 같이, 상기 고정바(28)를 상측으로 잡아당길 수 있는 다양한 종류의 장치를 이용할 수 있다.In the present embodiment, the chip bonder head for mounting the semiconductor chip 4 on the FPC is illustrated, but the structure of the chip bonder head is not the FPC, but the semiconductor chip 4 in the lead frame of the general PCB, the semiconductor package, or the substrate. It can also be applied to chip bonder heads for mounting). In addition, although the lifting drive mechanism 34 uses a pneumatic cylinder, as needed, various kinds of devices capable of pulling the fixing bar 28 upward, such as a hydraulic cylinder, may be used.

이상에서와 같이 본 발명에 의하면, 공압실린더(34)에 의해 승강되는 고정바(28)를 이용하여, 헤드블록(6)과 상부조절블록(8) 및 하부조절블록(10)을 상호 고정할 수 있도록 구성하므로써, 구조가 간단하고, 자기장에 의한 칩의 불량발생을 방지할 수 있도록 된 새로운 구조의 칩본더 헤드를 제공할 수 있다.According to the present invention as described above, by using the fixing bar 28 which is elevated by the pneumatic cylinder 34, the head block 6 and the upper control block 8 and the lower control block 10 can be fixed to each other. In this configuration, it is possible to provide a chip bonder head having a new structure, which is simple in structure and prevents chip defects caused by a magnetic field.
