본원발명은 이와 같은 배경하에서 태동하게 된 것이다.It was against this background that the present invention was born.

동박표면에 드라이 필름을 열압착하는 핫롤부(100,200)로 구성하는 핫롤장치에 있어서,In a hot roll device comprising a hot roll section (100, 200) that thermally presses a dry film onto a copper surface,
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 portion (110, 210) of the hot roll portion (100, 200) are configured differently, and when the cross-sectional diameter of the central portion of the hot roll portion (100, 200) is a and the cross-sectional diameter of the hot roll end portion (110, 210) is b, the hot roll device is configured such that a>b.
이렇게 구성하면 중앙부위에 밀착되는 압력이 집중 되어 표면눌림부위에 드라이필름의 에어포켓이 발생되지 않게 되는 것이다.By configuring it this way, the pressure applied to the central area is concentrated, preventing air pockets in the dry film from forming in the pressed surface area.
이로 인한 덴트, 밀착력저하 및 표면눌림이 없어지는 것이다.This eliminates dents, loss of adhesion, and surface pressure.
여기서 상기 크라운부(120)와 상기 핫롤단부(110,210)에 대한 길이부의 측면부 구성은 크라운타입의 형상을 갖도록 구성하되, Here, the side portion of the length of the crown portion (120) and the hot roll portion (110, 210) is 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.It is preferable that the central portion of the hot roll portion (100, 200) be convex and configured in an arc shape to the hot roll end portions (110, 210) which are both ends of the hot roll portion (100, 200), so as to improve adhesion and reduce the defect rate when thermally pressing the dry film onto the copper surface.
여기서 상기 a와 상기 b와의 관계는 a ≥ 1.002b 인 조건을 만족하도록 구성하는 것이 바람직하다.Here, it is desirable to configure the relationship between a and b so as 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 section (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 is c, then the relationship between a, b, and c satisfies c≒0.0003(a-b).
여기서 핫롤부의 길이는 660mm이다.The length of the hot roll here is 660 mm.
도면에서는 크라운부 지름이 90.2mm 이고 핫롤단부의 지름은 90mm 가 가장좋은 효과를 보이는 것이다.In the drawing, the diameter of the crown part is 90.2 mm and the diameter of the hot roll end part is 90 mm, which shows the best effect.
본원발명의 도면 3a 내지 도면4b에 대하여 설명하면 하기와 같다.The drawings 3a to 4b of the present invention are described 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.Drawings 3b and 4b show that when a dry film is laminated on a substrate having a surface step of 8 um, only 20% of the dry film adheres before the improvement of the hot roll as in Drawing 3a, whereas when the present invention is applied as in Drawing 4a, the dry film maintains adhesion up to 70%.
도면3a 내지 도면 4b는 20개를 테스트 진행하여 14개의 제품에 드라이필름이 떨어지지 않는 결과를 보이는 것이다.Drawings 3a to 4b show the results of testing 20 products and showing that the dry film did not come off in 14 products.
도면5에서는 AOI(Auto Optical Inspection) Open 불량률의 개선전 개선후의 수치에 관한 것이다.Figure 5 shows the numerical 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.This is a comparison of the open defect rate that occurred when applying a hot roll part having a crown part to which the present invention is applied to a mass-produced product and the hot roll part corresponding to the background technology.
배경기술로는 오픈불량률이 0.46% 인데 대하여 본원발명을 적용한 결과 0.27%의 불량률로 불량이 개선되었다.As a background technology, the open defect rate was 0.46%, but as a result of applying the present invention, the defect rate was improved to 0.27%.
즉 본원발명을 적용한 결과 배경기술보다 오픈불량률을 41% 감소한 결과를 보인다.In other words, the result of applying the present invention shows a 41% reduction in open defect rate compared to the background technology.
