일반적으로 반도체 소자에 은액을 일정두께로 도포하여 제품의 특성을 향상시키도록 하고 있다.Generally, silver liquid is applied to a semiconductor device at a predetermined thickness to improve product characteristics.
종래에는 은 페이스트를 반도체 소자에 일정두께로 도포하기 위하여 도 1에 도시된 바와같이 VAT(1)내에 은액(2)을 넣고 VAT(1)중심부에 설치된 스틸러(3)를 회전시켜 점도를 측정하였다.Conventionally, in order to apply a silver paste to a semiconductor device with a predetermined thickness, as shown in FIG. .
그러나, 이와같은 종래 기술에 있어서는, VAT(1)내의 은액(2)이 일정점도를 유지하고 있는지를 측정하기 어려웠으며, 점도의 변화 또한 측정하기가 어려운 문제가 있었다.However, in such a prior art, it is difficult to measure whether the silver liquid 2 in the VAT 1 maintains a constant viscosity, and there is a problem that the change in viscosity is also difficult to measure.
본 고안은 페이스트의 점도 유지장치는 이와같은 종래의 문제점을 해결하기 위하여 안출한 것으로, 점도를 측정하여 이를 디지탈상의 수치로 나타내주고 설정치의 점도를 벗어날 경우 센서의 작동으로 희석제를 보충하여 줌으로써 은 페이스트의 점도를 항상 일정하게 유지할 수 있도록 하는 은 페이스트의 점도 유지장치를 제공하는데 그 목적이 있다.The present invention has been devised to solve the conventional problems of the viscosity of the paste, which measures the viscosity and indicates it as a digital value, and when the viscosity is out of the set value, the diluent is replenished by the operation of the sensor. It is an object of the present invention to provide a viscosity maintaining device of a silver paste, which can maintain a constant viscosity of a silver paste at all times.
이와같은 목적을 달성하기 위한 본 고안은 은액을 뿜어주기 위한 펌프와, 상기 펌프로부터의 은액이 주입되는 제1VAT와, 상기 제1VAT주위에 설치된 제2VAT와, 상 기 제2VAT를 통하여 낙하되는 은액을 저장하는 은액저장통과, 상기 은액저장통내에 설치되어 점도를 측정하여 이를 디지탈수치로 디스플레이하는 점도측정기와, 상기 점도가 설정치를 벗어날 경우 이를 감지하여 희석제를 보충하여 주도록 하는 센서를 구비하여 구성함을 특징으로 한다.The present invention for achieving the above object is a pump for spraying the silver liquid, the first VAT is injected into the silver liquid from the pump, the second VAT installed around the first VAT, and the silver liquid falling through the second VAT And a viscometer for storing the silver liquid reservoir, the viscometer for installing the silver liquid reservoir and measuring the viscosity and displaying it as a digital value, and detecting the viscosity when the viscosity is out of the set value and replenishing the diluent. It is done.

도 2는 본 고안 은 페이스트의 점도 유지장치의 구성도로, 은액을 뿜어주기 위한 펌프(11)와, 상기 펌프(11)로부터의 은액이 주입되는 제1VAT(12)와, 상기 제1VAT(12)주위에 설치된 제2VAT(13)와, 제2VAT(13)를 통하여 낙하되는 은액을 저장하는 은액저장통(14)과, 상기 은액저장통(14)내에 설치되어 점도를 측정하여 이를 디지탈수치로 디스플레이하는 점도측정기(15)와, 상기 점도가 설정치를 벗어날 경우 이를 감지하여 희석제를 보충하여 주도록 하는 센서(16)로 구성된 것이다.2 is a configuration diagram of a viscosity paste holding device of the present invention, a pump 11 for spouting a silver liquid, a first VAT 12 into which the silver liquid from the pump 11 is injected, and the first VAT 12. The second VAT 13 and the silver liquid storage container 14 for storing the silver liquid falling through the second VAT 13 installed in the periphery, and the viscosity is provided in the silver liquid storage container 14 to measure the viscosity and display it as a digital value. The measuring device 15 and the sensor 16 for detecting the viscosity when the viscosity is out of the set value to replenish the diluent.
단, 도면중 미설명 부호 17은 은액이 통과할 수 있도록 설치된 파이프이다.However, reference numeral 17 in the drawings is a pipe installed so that the silver liquid can pass through.
이와같이 구성된 본 고안은 먼저 펌프(11)에 의해 은액저장통(14)의 은액이 제1VAT(12)내로 주입된다.In the present invention configured as described above, the silver liquid of the silver liquid storage container 14 is first injected into the first VAT 12 by the pump 11.
이렇게 주입되는 은액이 제1VAT(12)를 넘게 되면, 제2VAT(13)의 출구를 통하여 낙하하게 되고, 이와같이 낙하한 은액은 다시 은액저장통(14)내로 모이게 되는데, 이때 은액저장통(14)내에 설치된 점도측정기(15)에서는 은액의 점도를 측정하여 이를 디지탈 수치로 표시하여 준다.When the injected silver liquid exceeds the first VAT 12, the silver liquid falls through the outlet of the second VAT 13, and the dropped silver liquid is collected into the silver liquid reservoir 14 again. In the viscosity measuring device 15, the viscosity of the silver solution is measured and displayed as a digital value.
또한, 이렇게 측정된 은액의 점도가 센서(16)에 의해 감지되는데, 만일 설정치의 점도를 벗어날 경우 센서(16)에서 이를 감지하여 희석제를 보충하도록 동작하게 된다.In addition, the viscosity of the silver liquid thus measured is sensed by the sensor 16, and if it is out of the viscosity of the set value is detected by the sensor 16 to operate to replenish the diluent.
따라서, 은액의 점도가 항상 일정하게 유지되어 반도체 소자에 은액을 일정 점도로 도포할 수 있게 된다.Therefore, the viscosity of the silver liquid is always kept constant so that the silver liquid can be applied to the semiconductor element at a constant viscosity.
본 고안 은 페이스트의 점도 유지장치에 의하면, 은 페이스트의 점도관리를 정확히 할 수 있음은 물론 (-)극성을 인출하는 은 페이스트의 두께가 균일해져 손실값의 균형을 유지할 수 있으며, 양질의 제품을 얻을 수 있는 효과가 있다.According to the device for maintaining the viscosity of the silver paste, the viscosity management of the silver paste can be precisely controlled, and the thickness of the silver paste which pulls out the negative polarity becomes uniform, so that the loss value can be balanced. There is an effect that can be obtained.
