포고 핀을 이용한 하드 디스크 드라이브 테스트용 착탈지그의 드라이브 착탈방법Drive removal method of detachable jig for hard disk drive test using pogo pin

본 발명은 하드 디스크 드라이브(Hard Disk Drive: 이하 HDD라 칭함) 제조 공정에 관한 것으로, 특히 포고 핀(pogo pin)을 이용한 HDD 테스트용 착탈지그의 드라이브 착탈방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hard disk drive (hereinafter referred to as HDD) manufacturing process, and more particularly to a drive detachment method of a detachable jig for HDD test using a pogo pin.

컴퓨터시스템의 보조기억장치로 널리 사용되고 있는 하드 디스크 드라이브(Hard Disk Drive)는 도 1에 도시된 바와 같은 일련의 제조공정 절차를 거쳐 하나의 완성된 제품으로서 출하된다.A hard disk drive, which is widely used as an auxiliary memory device of a computer system, is shipped as a completed product through a series of manufacturing process procedures as shown in FIG.

도 1은 종래 하드 디스크 드라이브(Hard Disk Drive:이하 HDD라함)의 제조공정단계를 설명하기 위한 제조공정 주요절차를 도시한 도면으로서, 크게 6단계로 구분된다. 도 1을 참조하면, 제조공정의 제1단계(Ⅰ)인 HDA(Hard Disk Assembly) 조립공정은 HDD의 기구부인 HDA(Head Disk Assembly)를 조립하는 공정으로서 클린 룸(clean room)내에서 이루어진다. 제조공정의 제2단계(Ⅱ)인 서보라이트 공정은 액츄에이터(actuator)의 서보제어를 위한 서보 패턴을 디스크상에 기록하는 공정으로서 서보라이터(servo writer)에 의해 수행된다. 제조공정의 제3단계(Ⅲ)인 기능 테스트공정(function test)은 상기 HDA 조립공정에서 만들어진 HDA와 PCBA(Printed Circuited Board Assembly) 조립공정(통상 HDA조립공정후 수행됨)에서 만들어진 PCBA를 결합시켜 행해지는 최초의 테스트로서 HDA와 PCBA가 정상적으로 매치(match)되어 동작하는지를 테스트한다. 이때 약 20분∼25분간의 기본 테스트를 특정 테스트 시스템과 결합하여 수행한다. 제조공정의 제4단계(Ⅳ)인 번-인(burn-in) 테스트 공정은 HDD의 제조공정중 가장 긴 시간이(통상 8시간 내지 16시간)이 소요되는 공정으로서 별도의 테스트 시스템 없이 번-인 룸(burn-in room)내의 래크(rack)상에서 자체 프로그램(펌웨어)에 의해서 수행된다. 이러한 번-인 테스트 공정은 소비자가 하드 디스크 드라이브를 정상적으로 사용할 수 있도록 하기 위해 디스크상에 존재하는 디펙(defect)부분을 미리 찾아내어 드라이브 사용시 디펙부분을 피해갈 수 있도록 선조치하는 공정을 말한다. 제조공정의 제5단계(Ⅴ)인 최종 테스트(final test) 공정은 상기 번-인 테스트 공정에서 통과한 HDD 세트(set)가 정상적으로 디펙처리 되었는가를 확인하기 위한 공정으로서 특정 테스트시스템을 이용하여 HDD 세트 마다의 디펙처리 상태를 테스트한다. 최종 테스트 공정을 마친 HDD 세트는 제조공정의 제6단계(Ⅵ)인 출하검사공정, 포장 및 출하공정을 거쳐 하나의 완성된 제품으로 출하된다.FIG. 1 is a diagram illustrating main steps of a manufacturing process for explaining a manufacturing process step of a conventional hard disk drive (hereinafter referred to as an HDD), which is divided into six steps. Referring to FIG. 1, a hard disk assembly (HDA) assembling process, which is a first step (I) of a manufacturing process, is performed in a clean room as a process of assembling a head disk assembly (HDA) which is a mechanical part of an HDD. The servolite process, which is the second stage (II) of the manufacturing process, is a process of recording a servo pattern for servo control of an actuator on a disk and performed by a servo writer. The function test, which is the third step (III) of the manufacturing process, is performed by combining the HDA made in the HDA assembly process and the PCBA made in the printed circuited board assembly (PCBA) assembly process (usually performed after the HDA assembly process). The first test is to test that the HDA and PCBA work correctly. A basic test of about 20 to 25 minutes is then performed in combination with a specific test system. The burn-in test process, which is the fourth stage (IV) of the manufacturing process, is the process that takes the longest time (usually 8 to 16 hours) of the HDD manufacturing process. It is performed by its own program (firmware) on a rack in a burn-in room. The burn-in test process refers to a process of finding defects existing on the disk in advance so that consumers can use the hard disk drive normally, and preemptively avoiding defects when using the drive. The final test process, which is the fifth step (V) of the manufacturing process, is a process for checking whether the HDD set passed in the burn-in test process is normally defected. Test the defect state for each set. After the final test process, the HDD set is shipped as a finished product through the shipment inspection process, packaging and shipment process, which is the sixth step (VI) of the manufacturing process.

도 2는 도 1와 같은 제조공정중에서 최종 테스트 공정(V단계)을 수행하기 위해 테스트 장비의 PC케이블 및 파워케이블을 테스트자가 HDD의 PC컨넥터 및 파워 컨넥터에 연결시키는 동작을 보여주고 있다. 도 2를 참조하면, 테스트 수행자 2가 테스트할 HDD 4를 테스트 장비 6의 빈 슬롯에 안착시킨 후 상기 테스트 장비 6에서 연장된 39핀의 케이블(PC케이블) 8과 4핀 케이블(파워케이블) 10을 하드 디스크 세트 PCBA에 있는 39핀 컨넥터 12 및 4핀 컨넥터 14 각각에 수동 연결시킨다.FIG. 2 illustrates an operation in which a tester connects a PC cable and a power cable of the test equipment to the PC connector and the power connector of the HDD in order to perform a final test process (step V) in the manufacturing process as shown in FIG. 1. Referring to FIG. 2, the test performer 2 seats the HDD 4 to be tested in an empty slot of the test equipment 6, and the 39-pin cable (PC cable) 8 and the 4-pin cable (power cable) 10 extended from the test equipment 6. To the 39-pin connector 12 and the 4-pin connector 14 on the hard disk set PCBA.

최종테스트시 테스트 장비의 케이블과 HDD의 컨넥터 착탈과정에서, 연장된 각 케이블을 HDD세트에 장착하기는 상기한 바와 같이 어렵지 않으나 HDD 세트에서 분리할 때 순간적으로 많은 힘이 가해야 하며 이러한 동작을 장시간 반복할 시 작업자는 많은 피로감을 느끼게 된다. 또한 각 테스트 장비의 케이블을 HDD세트의 컨넥터의 수직방향으로 정확히 떼어내지 못하면 HDD 컨넥터가 휘어지게 되므로 마지막 공정에서 하나 하나의 목시(目視)검사를 통해 휘어진 컨넥터를 펴주어야 한다. 그리고 테스트 장비에서 연장된 케이블을 오래 사용하다 보면 케이블의 구멍이 헐거워져 테스트 수행시 제품불량을 유발시킬 수 있다.During the final test, it is not difficult to attach each extended cable to the HDD set in the process of detaching the cable of the test equipment and the connector of the HDD. However, when detaching from the HDD set, a large amount of momentary force must be applied. When repeated, the worker feels a lot of fatigue. In addition, if the cable of each test equipment is not detached correctly in the vertical direction of the connector of the HDD set, the HDD connector will bend. Therefore, the bent connector must be unfolded by visual inspection one by one in the final process. And prolonged use of extended cables in test equipment can cause loose holes in the cables, which can lead to product defects when performing tests.

따라서 본 발명의 목적은 하드 디스크 드라이브 테스트시 테스트 장비의 케이블에서 하드 디스크 드라이브의 컨넥터의 착탈을 보다 용이하게 하기 위한 착탈지그의 착탈방법을 제공하는데 있다.Accordingly, an object of the present invention is to provide a detachable jig detachment method for more easily detaching the connector of the hard disk drive from the cable of the test equipment during the test of the hard disk drive.
