Field of the Invention The present invention relates to a semiconductor package tester, and more particularly, to a contactor of a semiconductor package tester in contact with a pin of the semiconductor package for electrically connecting the semiconductor package and the tester. .

제 1 도는 종래 기술에 따른 핸들러(반도체패키지 검사장치) 콘택터(Handler Contactor)의 구성도로서, 이에 도시된 바와 같이 검사를 받는 반도체패키지(10)와 그 패키지(10)를 검사하기 위한 테스트신호를 입출력하는 피씨비(PCB)회로(20)를 전기적으로 연결하는 판스프링 콘택터(30)가 그의 탄성력에 의해 상기 패키지(10)의 핀(11)과 접촉되었다. 즉, 판스프링 콘택터(30)는 피씨비회로(20)의 테스트신호 입출력단자와 연결된 일측이 고정되고, 그 일측을 지지축으로 하는 탄성력에 따라 그의 타측이 좌우로 움직이는 도체판으로서, 그의 타측이 패키지(10)의 핀(11)과 접촉됨으로써, 일측을 통해 입력되는 피씨비회로(20)의 테스트신호가 타측의 접촉점을 통해 패키지(10)의 핀(11)으로 출력된다(이와 반대되는 경로로 패키지의 출력신호가 피씨비회로로 전송된다).FIG. 1 is a block diagram of a handler (semiconductor package inspection device) contactor according to the prior art, and as shown therein, a test signal for inspecting a semiconductor package 10 to be inspected and a package 10 thereof. The leaf spring contactor 30 that electrically connects the input / output PCB circuit 20 is in contact with the pin 11 of the package 10 by its elastic force. That is, the leaf spring contactor 30 is a conductor plate having one side connected to a test signal input / output terminal of the PCB circuit 20 fixed thereto, the other side of which is moved left and right according to an elastic force having one side as a support shaft, and the other side of which is a package. By contacting the pin 11 of the (10), the test signal of the PCB circuit 20 input through one side is output to the pin 11 of the package 10 through the contact point of the other side (package in the opposite path Output signal is transmitted to PCB circuit).

이와 같은 판스프링 콘택터(30)는 패키지(10)의 전체 핀(11)과 피씨비회로(20)의 입출력단자를 일대일로 연결하도록 배치되어, 피씨비회로(20)의 테스트신호를 패키지(10)로 전달함과 아울러 그 테스트신호에 따른 패키지(10)의 결과신호를 피씨비회로(20)로 전달한다.The leaf spring contactor 30 is arranged to connect the entire pin 11 of the package 10 and the input / output terminals of the PCB circuit 20 in a one-to-one manner, thereby connecting the test signal of the PCB circuit 20 to the package 10. In addition to the transfer, the result signal of the package 10 according to the test signal is transferred to the PCB circuit 20.
