Description
본원발명은 동박표면에 드라이 필름을 열압착하는 핫롤부로 구성하는 핫롤장치에 관한 것이다.The present invention relates to a hot roll device consisting of a hot roll unit that heat-presses a dry film on the surface of copper foil.
도6은 종래기술을 설명하기위한 장치의 구성도이다.Figure 6 is a configuration diagram of a device for explaining the prior art.
박막의 구리판의 전후면에 드라이 필름을 핫롤부를 통하여 밀착시키는 것을 보이는 도이다.This diagram shows dry film being adhered to the front and back surfaces of a thin copper plate through a hot roll unit.
도7은 종래기술을 적용할 경우의 에어포켓이 발생하는 것을 보이는 도이다.Figure 7 is a diagram showing the occurrence of air pockets when applying the prior art.
도7은 도면9에서 보는 바와 같이 중앙부에 압력을 가하지 못하게 되어 밀착불량이 발생하게 되는 것으로 표면눌림부위에 드라이필름에어포켓이 발생하는 것이이다.As shown in Figure 7, as shown in Figure 9, pressure cannot be applied to the central part, resulting in poor adhesion, and dry film air pockets are generated in the area where the surface is pressed.
이로 인하여 종래기술을 적용하는 경우에 도8a 내지 도면 8c에서 보는 바와 같이 필름의 표면 단차를 극복하지 못하여 오픈불량이 발생하는 것을 보이는 도이다.As a result, when applying the prior art, the surface level of the film cannot be overcome as shown in Figures 8a to 8c, resulting in open defects.
도8a는 덴트가 발생하는 것을 보이는 것이고 도면8b는 밀착력이 저하되는 것을 보이는 도이다. 도면 8c는 표면눌림이 발생하여 오픈이 발생하는 것을 보이는 도이다.Figure 8a shows a dent occurring, and Figure 8b shows a decrease in adhesion. Figure 8c is a diagram showing that openness occurs due to surface compression.
도면9는 중앙부에 밀착불량이 발생하는 것을 보이는 종래기술에 관한 도이다.Figure 9 is a diagram of the prior art showing that adhesion failure occurs in the central portion.
도면10은 기술이 진보함에 따라 기판 및 드라이필름이 점점 얇아짐으로 핫롤부적용시에 에어포켓이 발생할 수 있는 확률이 더 높아질 가능성이 더 많은 것이다.Figure 10 shows that as technology advances, the substrate and dry film become thinner, so the probability of air pockets occurring when hot rolls are not applied increases.
본원발명은 이와 같은 배경하에서 태동하게 된 것이다.The present invention was born under this background.

동박표면에 드라이 필름을 열압착하는 핫롤부(100,200)로 구성하는 핫롤장치에 있어서,In the hot roll device consisting of a hot roll unit (100, 200) that heat-presses a dry film on the surface of copper foil,
상기 핫롤부(100,200)의 중앙부인 크라운부(120)와 상기 핫롤부(100,200)의 핫롤단부(110,210)의 단면지름을 상이하게 구성하되, 상기 핫롤부(100,200)의 중앙부단면지름을 a라하고 상기 핫롤단부(110,210)의 단면지름을 b라 할 때 a>b 가 되도록 핫롤장치를 구성하는 것이다.The cross-sectional diameters of the crown portion 120, which is the central portion of the hot roll portion 100, 200, and the hot roll end portions 110, 210 of the hot roll portion 100, 200 are configured differently, and the cross-sectional diameter of the central portion of the hot roll portion 100, 200 is a. When the cross-sectional diameter of the hot roll ends 110 and 210 is b, the hot roll device is configured so that a > b.
이렇게 구성하면 중앙부위에 밀착되는 압력이 집중 되어 표면눌림부위에 드라이필름의 에어포켓이 발생되지 않게 되는 것이다.If configured in this way, the pressure of close contact is concentrated in the central area, preventing air pockets in the dry film from being created in the area where the surface is pressed.
이로 인한 덴트, 밀착력저하 및 표면눌림이 없어지는 것이다.This eliminates dents, loss of adhesion, and surface compression.
여기서 상기 크라운부(120)와 상기 핫롤단부(110,210)에 대한 길이부의 측면부 구성은 크라운타입의 형상을 갖도록 구성하되, Here, the crown portion 120 and the side portions of the length portions of the hot roll ends 110 and 210 are configured to have a crown-type shape,
상기 핫롤부(100,200)의 중앙부는 볼록하여 상기 핫롤부(100,200)의 양측단부인 상기 핫롤단부(110,210)에 이르기까지 아크형상으로 구성하여 상기 동박표면에 상기 드라이필름을 열압착할 때에 밀착력을 개선하고 불량율을 감소시키는 것이 바람직하다.The central portion of the hot roll portion (100, 200) is convex and has an arc shape extending to the hot roll ends (110, 210), which are both ends of the hot roll portion (100, 200), thereby improving adhesion when heat-pressing the dry film on the copper foil surface. It is desirable to reduce the defect rate.
여기서 상기 a와 상기 b와의 관계는 a ≥ 1.002b 인 조건을 만족하도록 구성하는 것이 바람직하다.Here, the relationship between a and b is preferably configured to satisfy the condition that a ≥ 1.002b.
핫롤단부(110,210)의 단면지름을 b라 할 때 a>b 가 되도록 핫롤장치를 구성하는 것이다.When the cross-sectional diameter of the hot roll ends (110, 210) is b, the hot roll device is configured so that a>b.
핫롤부의 길이를 c라고 하면 a,b,c와의 관계는 c≒0.0003(a-b) 를 만족하는 것이다.If the length of the hot roll part is c, the relationship between a, b, and c satisfies c≒0.0003(a-b).
여기서 핫롤부의 길이는 660mm이다.Here, the length of the hot roll part is 660mm.
도면에서는 크라운부 지름이 90.2mm 이고 핫롤단부의 지름은 90mm 가 가장좋은 효과를 보이는 것이다.In the drawing, the crown diameter is 90.2mm and the hot roll end diameter is 90mm, which shows the best effect.
본원발명의 도면 3a 내지 도면4b에 대하여 설명하면 하기와 같다.The description of Figures 3a to 4b of the present invention is as follows.
도면 3b와 도면 4b는 표면단차가 8um 형성된 기판에 드라이필름을 라미네이트하였을 경우에 도면3a와 같은 핫롤부인 개선 전에는 20%만 밀착되었는데 비하여 도면 4a와 같이 본원발명을 적용할 경우에는 70%까지 드라이필름이 밀착유지 되는 결과를 갖게 되는 것이다.Figures 3b and 4b show that when a dry film is laminated to a substrate with a surface step of 8um, only 20% of the adhesion is achieved before the improvement of the hot roll resistance as shown in Figure 3a. However, when the present invention is applied as shown in Figure 4a, the dry film adheres by up to 70%. The result is that this is maintained closely.
도면3a 내지 도면 4b는 20개를 테스트 진행하여 14개의 제품에 드라이필름이 떨어지지 않는 결과를 보이는 것이다.Figures 3a to 4b show the results showing that dry film did not fall on 14 products after testing 20 products.
도면5에서는 AOI(Auto Optical Inspection) Open 불량률의 개선전 개선후의 수치에 관한 것이다.Figure 5 shows the values of the AOI (Auto Optical Inspection) Open defect rate before and after improvement.
본원발명을 적용한 크라운부를 가지고 있는 핫롤부를 양산제품에 적용하여 배경기술에 해당하는 핫롤부 적용시 발생했던 Open 불량률과 비교한 것이다.The hot roll part with the crown part to which the present invention was applied was applied to a mass-produced product and compared with the open defect rate that occurred when applying the hot roll part corresponding to the background technology.
배경기술로는 오픈불량률이 0.46% 인데 대하여 본원발명을 적용한 결과 0.27%의 불량률로 불량이 개선되었다.In the background technology, the open defect rate was 0.46%, but as a result of applying the present invention, the defect was improved to 0.27%.
즉 본원발명을 적용한 결과 배경기술보다 오픈불량률을 41% 감소한 결과를 보인다.In other words, as a result of applying the present invention, the open defect rate is reduced by 41% compared to the background technology.
