본 발명은 탄성을 갖는 메탈마스크(metal mask)에 관한 것으로서, 더욱 상세하게는 표면실장 부품이 장착되는 회로기판에 크림 납(cream solder)을 사용하여 크림 납땜(cream soldering)할 때 사용되는 탄성을 갖는 메탈마스크에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal mask having elasticity, and more particularly to elasticity used when cream soldering using a cream solder on a circuit board on which a surface mount component is mounted. It relates to a metal mask having.

근래에 이르러 복잡한 회로기판에 많은 부품을 깨끗하고, 신속하게 납땜하기 위하여 납땜할 위치에 구멍이 뚫린 메탈마스크를 이용하여 크림 납을 그 구멍에 밀어넣어서 표면실장 부품을 회로기판에 장착시키는 인쇄형식의 크림 납땜(cream soldering)을 한다. 따라서 상기 메탈마스크는 크림 납땜 공정에 있어서, 납땜품질을 좌우하는 중요한 부품이라 할 수 있다.In recent years, in order to clean many parts of a complicated circuit board quickly and cleanly, a printed mask type is used to mount the surface-mounted parts to the circuit board by inserting the cream lead into the hole using a metal mask having a hole in the place where the solder is to be soldered. Cream soldering is done. Therefore, the metal mask may be regarded as an important component that determines soldering quality in a cream soldering process.

제1도는 종래의 메탈마스크의 주요부를 도시한 평면도이고, 제2도는 제1도의 측면도이다. 도시된 바와 같이, 메탈마스크(1)는 프레임(3)에 화학섬유 또는 금속(예:Ni) 성분의 매쉬 스크린(mesh screen:4)에 의하여 일정한 탄성을 유지하면서 고정되어 있다.FIG. 1 is a plan view showing main parts of a conventional metal mask, and FIG. 2 is a side view of FIG. As shown, the metal mask 1 is fixed to the frame 3 while maintaining a constant elasticity by a mesh screen 4 of chemical fibers or metal (eg, Ni).

즉, 상기 프레임(3)에 접착제로 매쉬 스크린(4)을 접착한 후, 매쉬 스크린(4)의 내측 가장자리와 메탈마스크부(1)의 외측 가장자리를 접착제로 접착한다. 그리고 그 접착부분에 접착용 테이프(tape:2)를 붙여 그 부위를 매끄럽게 처리하였다.That is, after adhering the mesh screen 4 to the frame 3 with an adhesive, the inner edge of the mesh screen 4 and the outer edge of the metal mask part 1 are bonded with an adhesive. Then, an adhesive tape (tape: 2) was attached to the adhesive portion to smoothly treat the portion.

상술한 바와 같이, 종래의 메탈마스크는 프레임(3)과 매쉬 스크린(4)을 접착하고 다시 매쉬 스크린(4)과 메탈마스크부(1)를 접착하는 공정을 거쳐야 함으로 제조공수 및 원가가 상승하는 문제점이 있었다. 그리고, 크림 납땜할 때 스퀴지(squeegee)가 상기 접착부위(5)를 건드려서 접착부위(5)의 장력을 감소시키거나, 여러번 사용하면 접착부위(5)에서 장력이 감소하여 납땜불량을 유발시키는 문제점이 있었다.As described above, the conventional metal mask has to go through the process of adhering the frame 3 and the mesh screen 4, and then again adhering the mesh screen 4 and the metal mask portion 1 to increase the manufacturing labor cost and cost There was a problem. In addition, when cream soldering, a squeegee touches the adhesive portion 5 to reduce the tension of the adhesive portion 5, or when used several times, the tension is reduced at the adhesive portion 5 to cause poor soldering. There was this.

따라서 본 발명의 목적은 상술한 종래의 문제점인 납땜불량을 방지하여 고품질의 납땜인쇄가 가능하며, 종래의 것보다 오래동안 사용할 수 있으며, 작업공수와 원가를 절감할 수 있는 탄성을 갖는 메탈마스크를 제공하는데 있다.Therefore, an object of the present invention is to prevent the soldering problem, which is the conventional problem described above, high-quality solder printing is possible, can be used for a longer time than the conventional, and has a metal mask having elasticity that can reduce the labor and cost To provide.

상기 목적을 달성하기 위한 본 발명에 따른 탄성을 갖는 메탈마스크는 크림 납땜을 하기 위한 개구부가 형성된 메탈마스크와, 상기 메탈마스크를 지지하기 위한 프레임과, 상기 메탈마스크의 가장자리 주위에 형성되어 상기 개구부에 유연한 탄성을 부여하기 위한 다수개의 탄성공을 구비한 것을 특징으로 한다.The metal mask having elasticity according to the present invention for achieving the above object is a metal mask having an opening for cream soldering, a frame for supporting the metal mask, and formed around the edge of the metal mask to the opening; It is characterized by having a plurality of elastic holes for imparting flexible elasticity.

이하 첨부된 도면을 참조하면서, 본 발명에 따른 바람직한 실시예를 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

제3도는 본 발명에 따른 탄성을 갖는 메탈마스크의 주요부를 도시한 평면도이고, 제4도는 제3도의 단면도이다. 도시된 바와 같이, 탄성을 갖는 메탈마스크는 메탈마스크부(10)와 프레임(20)으로 구성된다.3 is a plan view showing the main part of the elastic metal mask according to the present invention, Figure 4 is a cross-sectional view of FIG. As shown, the elastic metal mask is composed of a metal mask 10 and the frame 20.

상기 메탈마스크부(10)는 스테인레스로 만들어져 있으며, 이 메탈마스크부(10)에는 개구부(11)와 탄성부(12)로 되어 있다.The metal mask part 10 is made of stainless steel, and the metal mask part 10 includes an opening 11 and an elastic part 12.

상기 개구부(11)는 부품을 회로기판(30)에 크림 납땜하기 위하여 크림 납을 회로기판(30)에 인쇄 도포하기 위한 구멍(13)들이 형성된 부분이다.The opening 11 is a portion in which holes 13 are formed to print and apply cream lead to the circuit board 30 in order to cream solder the component to the circuit board 30.

상기 탄성부(12)는 상기 개구부(11)가 후술하는 프레임(20)의 지지를 받아 납땜할 때 회로기판과 밀착되도록 소정의 탄성을 가지도록 상기 개구부(11) 주위에 다수개의 탄성공(14)이 형성된 부분이다. 즉, 개구부(11)의 주위는 구멍의 크기와 수를 조절하여 적절한 탄성을 개구부(11)에 제공할 수 있다.The elastic part 12 has a plurality of elastic holes 14 around the opening 11 so as to have a predetermined elasticity so that the opening 11 is in close contact with the circuit board when soldered by the support of the frame 20 to be described later. ) Is formed. That is, the periphery of the opening 11 can be adjusted to provide a suitable elasticity to the opening 11 by adjusting the size and number of holes.

상기 프레임(20)은 상기 메탈마스크부(10)의 가장자리와 접착되어 그 메탈마스크부(10)를 지지하는 역할을 한다.The frame 20 is bonded to the edge of the metal mask part 10 to support the metal mask part 10.

상술한 바와 같이 구성된 본 고안에 따른 탄성을 갖는 메탈마스크 크림 납을 회로기판(30) 위에 인쇄도포하기 위하여 메탈마스크부(10)를 회로기판(30) 위에 위치시키면, 제4도에 도시된 바와 같이 상기 회로기판(30)의 상면은 안내판(40)과 같은 높이를 유지하고 있고, 프레임(20)과 메탈마스크부(10)가 직접 연결되어 있으므로 안내판(40)과 메탈마스크부(10) 그리고 회로기판(30)과 메탈마스크부(10) 사이의 간격을 최대로 줄일 수 있으므로 고품질의 인쇄도포상태를 얻을 수 있다.In order to apply the metal mask cream lead having elasticity according to the present invention configured as described above to be printed on the circuit board 30, the metal mask part 10 is placed on the circuit board 30, as shown in FIG. 4. As described above, the upper surface of the circuit board 30 maintains the same height as the guide plate 40, and the frame 20 and the metal mask part 10 are directly connected to each other, so that the guide plate 40 and the metal mask part 10 and Since the distance between the circuit board 30 and the metal mask part 10 can be reduced to the maximum, a high quality printing application state can be obtained.

그리고 메탈마스크를 여러번 사용하여도 메탈마스크부(10)의 탄성력에 변화가 없어 메탈마스크의 수명을 한층 더 연장시킬 수 있으며, 종래의 매쉬 스크린을 프레임에 부착하고 메탈마스크를 매쉬 스크린에 부착하는 작업공수와 매쉬 스크린의 원가를 절감할 수 있다.In addition, even if the metal mask is used several times, the elastic force of the metal mask unit 10 does not change, and thus the life of the metal mask can be further extended. The cost of man-hours and mesh screens can be reduced.
