Description

플렉시블 회로기판 테스트용 툴{The testing tool of flexible circuit board}The testing tool of flexible circuit board

본 발명은 휴대폰이나 디지털카메라 등에 내장된 소형 플렉시블 회로기판(PCB) 테스트용 툴에 관한 것으로 상세하게는 PCB의 회로패턴에 접촉되어 전기적 신호를 전달하는 툴의 다수 측정핀에 대한 안전을 최대한 확보하여 정밀성의 극대화를 꾀함은 물론 고가의 툴에 대한 반영구적인 사용을 도모하고자 한 것이다.
The present invention relates to a tool for testing a small flexible circuit board (PCB) embedded in a mobile phone or a digital camera, and more particularly, to secure the maximum safety of a plurality of measuring pins of a tool that is in contact with a circuit pattern of a PCB and transmits an electrical signal. In addition to maximizing precision, it aims to be a semi-permanent use of expensive tools.

일반적으로 휴대폰이나 디지털 카메라에 사용되는 플렉시블 회로기판(이하 '플렉시블PCB' 라 칭함)은 소형 및 세밀화된 패턴형성으로 그 작동 여부의 테스트가 매우 까다로운 문제점을 안고 있는 바, 근래 이러한 문제점을 해결하면서 그 테스트 작업의 신속,편리성을 추구하는 플렉시블PCB 테스트용 툴이 안출된 바 있다.In general, flexible circuit boards (hereinafter, referred to as flexible PCBs) used in mobile phones and digital cameras have small and fine pattern formation, which are very difficult to test for their operation. A tool for testing flexible PCBs has been devised for the rapid and convenient test operation.

이를 보다 상세히 설명하자면 플렉시블PCB의 작동유무 및 그 패턴의 접속불량을 검사하는 종래의 테스트 툴은 중앙부의 결합편(11)과 고정편(21)이 힌지(11') 결합됨과 동시에 그 일측 선단으로 각각 다수 측정핀(3)이 설치되는 가압부(12)와 안착부(22)가 형성되고 또 타측에는 탄성스프링(4)이 게재되어 상기 가압부(12)와 안착부(22)가 상호 밀착된 상태를 유지하도록 한 작동체(1)와 고정체(2)로 구성되는 것으로,To explain this in more detail, the conventional test tool for inspecting the operation of the flexible PCB and the connection failure of the pattern is coupled to the hinge 11 'at the same time as the coupling piece 11 and the fixing piece 21 in the center are coupled to one end of the same. The pressing part 12 and the seating part 22 in which a plurality of measuring pins 3 are installed are formed, respectively, and the elastic spring 4 is placed on the other side so that the pressing part 12 and the seating part 22 closely adhere to each other. It consists of an actuator (1) and a stationary body (2) to maintain the state,

플렉시블PCB의 테스트시 상기 고정체(2)로 부터 작동체(1)의 타측을 편심되게 눌러 일측 선단의 가압부(12)와 안착부(22)를 일정범위 벌어지도록 한 다음 그 내에 플렉시블PCB선단(a)을 밀어 넣어 누르고 있는 작동체(1)을 놓는다. 그러면 작동체(1)의 가압부(12)에 설치된 다수의 측정핀(3) 하단이 작동체(1)와 고정체(2) 사이에 게재된 탄성스프링(4)의 가압력에 의해 일정하게 플렉시블PCB선단(a)에 형성된 패턴과 가압 접촉되면서 전기적 신호를 검사장치(c)와 기기(도면의 미도시)로 전달하여 테스트가 이루어지게 한다. When testing the flexible PCB, the other side of the actuator 1 is eccentrically pressed from the fixed body 2 so that the pressurizing portion 12 and the seating portion 22 at one end are opened to a certain range, and then the flexible PCB tip is placed therein. Push in (a) to release the actuator (1). Then, the lower end of the plurality of measuring pins 3 installed on the pressing part 12 of the actuator 1 is constantly flexible by the pressing force of the elastic spring 4 placed between the actuator 1 and the fixture 2. The test is made by transferring an electrical signal to the inspection device (c) and the device (not shown in the drawing) while being in pressure contact with the pattern formed on the PCB tip (a).

측정핀(3)들은 상단이 검사장치(c)의 단자판(b)과 연결되어 전기적 신호를 위와 같이 전달하게 된다.
The measuring pins 3 are connected to the terminal plate b of the inspection device c to transmit the electrical signals as described above.

상술한 바와 같이 종래의 테스트 툴은 플렉시블PCB의 세밀화된 패턴의 테스트를 매우 신속하면서도 편리하게 도모하여 주는 이점을 제공하고 있음을 알 수 있다. 그러나 근래에 들어 상기 테스트 툴의 사용시 노출된 측정핀 구성으로 인해 잦은 파손과 그에 따른 고가의 비용손실 그리고 플렉시블PCB의 많은 테스트 오류 등으로 신뢰성 저하 및 기피현상이 일어나고 있음이 지적되었다.As described above, it can be seen that the conventional test tool provides an advantage of very quickly and conveniently testing the fine pattern of the flexible PCB. In recent years, however, it has been pointed out that the reliability of the evacuation phenomenon is caused by frequent breakage, high cost loss, and many test errors of the flexible PCB due to the configuration of the measuring pin exposed when the test tool is used.

즉, 전기한 구성을 살펴보면 다수의 측정핀이 작동체의 가압부에 끼움되어 그 하단부가 외부에 완전 노출되어 있음을 알 수 있는데, That is, looking at the above configuration, it can be seen that a plurality of measuring pins are fitted to the pressurization portion of the actuator so that the lower end thereof is completely exposed to the outside.

이 경우 취급 부주의 내지는 외부환경으로부터 측정핀이 쉽게 파손 및 훼손될 우려가 상당히 높아 고가의 비용적 손실을 초래함은 물론 작업의 효율성을 저해하게 되고, 특히 가장 대두되었던 문제가 플렉시블PCB선단을 밀어 넣거나 빼낼 때 조금의 부주의에도 플렉시블PCB와 소형이면서도 충격에 약한 측정핀이 서로 부딪쳐 상호 훼손되는 문제가 많았으므로 측정핀의 미세 휨에 의한 접촉불량으로 테스트의 잦은 오류가 일어나 제품의 신뢰성과 품질을 크게 저해하였던 문제가 있었다.In this case, there is a high possibility that the measuring pins can be easily broken and damaged from carelessness or external environment, which leads to expensive cost loss and impedes the efficiency of work. When pulling out, there was a problem that the flexible PCB and the small but weak measuring pin collide with each other even if there is little carelessness, so that they are mutually damaged. There was a problem.

또한 다수 측정핀들은 작동체와 고정체에 게재된 탄성스프링의 탄발력에 의해 플렉시블PCB를 가압접촉시키게 되는데, 만약 작업자가 작동체와 고정체의 누름 상태를 순간 일시적으로 해제할 경우, 탄성스프링의 탄발력이 순간 강하게 발생하면서 다수 측정핀들을 플렉시블PCB의 패턴에 타격시켜 패턴은 물론 측정핀의 훼손을 야기하였던 문제까지 지적되고 있었다.
In addition, the plurality of measuring pins are in pressure contact with the flexible PCB due to the elastic force of the elastic springs placed on the actuator and the stationary body. If the operator releases momentarily the pressing state of the actuator and the stationary body, The momentary force of the resilience occurred at the moment, hitting a plurality of measuring pins on the pattern of the flexible PCB caused the damage of the measuring pin as well as the pattern was pointed out.

본 발명은 전기한 종래의 플렉시블PCB 테스용 툴이 가지는 다수 문제를 보완하기 위하여 발명된 것으로 특히 작동체 일측에 형성된 가압부로 다수의 측정핀을 설치함에 있어서, 상기 가압부 하부위치에 완충스프링이 게재된 가압판을 소정의 간격을 두고 설치하여 그 유동에 의한 측정핀 인출을 유도하는 것으로, 다수 측정핀의 불필요한 노출을 방지함은 물론 플렉시블PCB의 회로패턴으로 측정핀이 보다 안정적으로 접촉이 이루어질 수 있도록 함에 그 기술적 과제의 주안점을 두고 발명된 것이다.
The present invention has been invented to solve a number of problems of the conventional flexible PCB test tool described above. In particular, in the case of installing a plurality of measuring pins with a pressing portion formed on one side of the actuator, a shock absorbing spring is placed at the lower portion of the pressing portion. The pressure plate is installed at predetermined intervals to induce the measurement pins to be pulled out by the flow, and to prevent unnecessary exposure of the plurality of measurement pins, and to allow the measurement pins to be more stably contacted by the circuit pattern of the flexible PCB. The invention has been invented focusing on the technical problem.

The seating part 22 It is preferable to form the shape of the flexible PCB front end (a) (part where the connection pattern to be tested) can be seated or a shape in which a connector (not shown) installed in the flexible PCB can be seated.


또한 본 발명에서는 상기 작동체(1)의 가압부(12) 하측으로 소정의 간격을 두고 가압판(5)을 마련하여 그 양측단이 이음핀(51)의 걸림턱(51')에 걸림,설치되도록 함과 동시에 이음핀(51)의 길이를 따라 소폭 상,하 유동 되도록 구성한다.
In addition, in the present invention, the pressing plate (5) is provided at a predetermined interval below the pressing unit 12 of the actuator (1) and both ends thereof are caught and installed on the locking step (51 ') of the joint pin (51). At the same time it is configured to flow slightly up and down along the length of the joint pin (51).

이를 보다 상세히 설명하자면, 도 3에서와 같이 작동체(1)와 고정체(2)의 타측단 즉, 탄성스프링(4)이 게재된 부위를 동시 또는 작동체(1)만을 누르게 되면 일측 가압판(5)과 안착부(22)가 상대적으로 벌어지면서 일정범위 개방되어 진다.
그러면 상기 개방된 가압판(5)과 안착부(22) 사이로 플렉시블PCB선단(a)을 삽입하여 안착부(22) 상에 위치시키는데(테스트 준비단계), 이때 가압부(12) 하측의 완충스프링(53)이 가압판(5)을 양측 이음핀(51)을 따라 하부로 밀어 가압부(12)로부터 일정거리를 가지도록 함과 동시에 가압판(5)내에 측정핀(3) 하단을 음폐시켜 플렉시블PCB선단(a)과 충돌을 예방한다.
이는 가압판(5)을 통해 측정핀(3)의 안전을 최대한 보장한 상태에서 플렉시블PCB선단(a)을 고정체(2)의 안착부(22)에 삽입되도록 하는 것으로, 상호간의 충돌방지로 작업의 효율성, 정밀성, 그리고 신속성이 증대되는 효과를 가지게 하였다.

한편 위 작용을 통해 고정체(2)의 안착부(22)로 플렉시블PCB선단(a)을 안전하게 정 위치시키면, 작업자는 작동체(1)와 고정체(2)의 누름상태를 해제하여 가압판(5)과 안착부(22)를 초기 상태로 가압 밀착시켜 테스트를 실시한다.
상세하게는 작동체(1)와 고정체(2)가 타측 탄력스프링(4)에 의해 초기 상태가 되면, 상기 작동체(1)는 그 복귀력에 의해 일측 가압부(12)를 하강시켜 먼저, 가압판(5)을 안착부(22)에 위치한 플렉시블PCB선단(a)으로 가압고정되게 하고 동시에 완충스프링(53)에 의해 유지된 가압판(5)과 가압부(12)사이의 폭 만큼 계속 더 진행(하강)하면서, 가압판(5)으로 가압부(12) 하부를 밀착시켜 측정핀(3) 하단이 가압판(5) 저면에 고정된 플렉시블PCB선단(a)에 형성된 패턴과 접촉되게 한다.
여기서, 가압판(5)은 플렉시블PCB선단(a)을 가압,고정하여 플렉시블PCB선단의 흔들림이나 이탈 등의 문제를 예방하고 또 측정핀(3)과의 정확한 접촉을 유도하며, 특히 작동체(1)의 복귀속도를 가압판(5)과 가압부(12) 사이의 다수 완충스프링(53)으로 일부 상쇄시켜 플렉시블PCB선단(a)과 가압판(5) 및 측정핀(3)의 접촉이 보다 안정적으로 이루어질 수 있도록 하였다.
참고로 상기 작동체(1)의 복귀속도를 상쇄시키지 않을 경우 플렉시블PCB선단(a)과 가압판(5)이 강하게 부딪쳐 플렉시블PCB의 위치를 흩트릴 우려가 있으므로 테스트의 오류를 유발하고 또 측정핀(3)의 하단이 도면에서와 같이 뾰족하여 플렉시블PCB의 패턴을 찍어 훼손시킬 수 있는 우려가 있다.

이상의 구체적인 실시 예를 통해 살펴본 본 발명은 작동체에 설치된 측정핀의 안전을 최대한 확보함과 동시에 테스트의 정밀성을 향상시켜 그 신뢰성의 극대화를 꾀하도록 하였다.The measuring pin 3 is usually connected to the upper end of the terminal plate (b) of the inspection device (c) to transmit the electrical signal.

To describe this in more detail, as shown in FIG. 3, when the other end of the actuator 1 and the fixture 2, that is, the portion where the elastic spring 4 is placed, is pressed simultaneously or only the actuator 1, one side of the pressure plate ( 5) and the seating portion 22 is relatively wide open while opening a certain range.
Then, the flexible PCB front end a is inserted between the open pressure plate 5 and the seating part 22 to be positioned on the seating part 22 (test preparation step), at which time the buffer spring under the pressing part 12 ( 53 pushes the pressure plate 5 downward along the both side joint pins 51 to have a certain distance from the pressure unit 12, and at the same time, the bottom of the measuring pin 3 in the pressure plate 5 is negatively swept. prevent conflicts with (a).
This allows the flexible PCB tip a to be inserted into the seating part 22 of the fixture 2 in the state of ensuring the safety of the measuring pin 3 through the pressure plate 5, thereby preventing collision between them. It has the effect of increasing efficiency, precision, and speed.

On the other hand, when the flexible PCB front end (a) is securely positioned to the seating portion 22 of the fixture 2 through the above action, the operator releases the pressing state of the actuator 1 and the fixture 2 to press the plate ( 5) and the seating portion 22 in the initial state in close contact with the test is carried out.
In detail, when the actuator 1 and the fixed body 2 are in an initial state by the other elastic spring 4, the actuator 1 lowers one side press part 12 by its return force, The pressure plate 5 is pressurized to the flexible PCB tip a located at the seating portion 22 and at the same time, the pressure plate 5 is further continued by the width between the pressure plate 5 and the pressure portion 12 held by the shock absorbing spring 53. While advancing (falling), the lower portion of the pressing portion 12 is brought into close contact with the pressing plate 5 such that the lower end of the measuring pin 3 is in contact with the pattern formed on the flexible PCB tip a fixed to the bottom of the pressing plate 5.
Here, the pressure plate 5 pressurizes and fixes the flexible PCB tip a to prevent problems such as shaking and detachment of the flexible PCB tip and induces accurate contact with the measuring pin 3, in particular, the actuator 1 ), Partly offset by the multiple buffer springs 53 between the pressure plate 5 and the pressure part 12, so that the contact between the flexible PCB tip a, the pressure plate 5 and the measuring pin 3 is more stable. It could be done.
For reference, if the return speed of the actuator 1 is not canceled, the flexible PCB front end a and the pressure plate 5 may be strongly collided to disperse the position of the flexible PCB, thereby causing a test error and measuring pin ( The lower end of 3) is sharp as shown in the drawing, so there is a risk of damaging the pattern of the flexible PCB.

The present invention, which has been discussed through the above specific embodiments, is intended to maximize the reliability of the test pin while ensuring the safety of the measuring pin installed in the actuator as much as possible and improving the precision of the test.
