Abstract
본 발명은 반도체 제조공정중 특정 공정전 리드프레임의 적합여부를 광섬유센서를 이용하여 구별하는 장치에 관한 것으로, 리드프레임의 이동중에 리드프레임의 사이드 레일에 접한 리드프레임의 이동경로상의 소정위치에 배치되어 리드프레임 및 리드프레임 사이를 고속으로 센싱하는 광섬유센서와, 상기 센서에 연결되어 센싱된 신호를 증폭하는 센서 증폭기와, 상기 센싱된 기호를 리드프레임수 계수신호를 변환하는 고속 카운터 모듈과, 기준 리드수가 설정된 기준모듈과, 상기 고속 카운터 모듈 및 기준 모듈 출력을 비교하여 일치하지 않을때 장비의 스톱명령을 출력시키는 비교부를 포함하는 것을 특징으로 하는 리드프레임 구별장치를 구비하여 구성된다.The present invention relates to an apparatus for distinguishing whether a lead frame is suitable before a specific process during a semiconductor manufacturing process by using an optical fiber sensor, and arranged at a predetermined position on a movement path of a lead frame in contact with a side rail of the lead frame during movement of the lead frame. A high speed counter module for converting the sensed symbol into a lead frame number counting signal, a fiber optic sensor for sensing a lead frame and a lead frame at high speed, a sensor amplifier connected to the sensor, and amplifying the sensed signal; Comprising a lead frame distinguishing device comprising a reference module for setting the number of leads, and a comparison unit for comparing the output of the high-speed counter module and the reference module and outputs a stop command of the equipment.
