Description

핫 프레스용 실리콘 패드{silicone pad for hot press}Silicone pad for hot press

본 발명은 핫 프레스용 실리콘 패드에 관한 것으로, 보다 상세하게는 PCB 또는 FPCB와 같은 회로기판에 절연수지층을 가열, 가압할 때 사용되는 것으로 재사용이 가능하도록 구성된 핫 프레스용 실리콘 패드에 관한 것이다.The present invention relates to a silicon pad for hot press, and more particularly, to a silicon pad for hot press used when heating and pressing an insulating resin layer on a circuit board such as a PCB or FPCB and configured to be reusable.

일반적으로 PCB 또는 FPCB와 같은 회로기판은 동박으로 구성된 회로가 노출되지 않도록 절연수지층이 적층되도록 제조된다.In general, a circuit board such as a PCB or FPCB is manufactured so that an insulating resin layer is laminated so that a circuit composed of copper foil is not exposed.

최근 전자제품의 소형화로 그 수요가 크게 증가하고 있는 FPCB는 회로기판 제조공정 중 핫 프레스를 통해 절연수지층을 형성시키는 핫 프레스 공정을 통해 폴리이미드 필름과 같은 수지계열의 필름을 가열, 가압하여 절연수지층을 형성하게 된다.FPCB, whose demand is increasing due to the recent miniaturization of electronic products, is insulated by heating and pressing a resin-based film such as a polyimide film through a hot press process that forms an insulating resin layer through hot pressing during the circuit board manufacturing process. A resin layer is formed.

핫 프레스 공정에서는 수지계열의 필름이 들뜨지 않고 고르게 부착시키기 위해 적게는 수 장에서부터 많게는 수십 장에 이르는 크라프트 페이퍼(Kraft Paper)를 회로기판의 상,하부에 적층하여 프레스가 크라프트 페이퍼를 통해서 수지계열의 필름을 가압할 때 압력분포가 균일하도록 실시되고 있다.In the hot press process, in order to adhere the resin-based film evenly without lifting it, from a few sheets to a maximum of several tens of kraft papers are laminated on the top and bottom of the circuit board, and the press is made of resin-based films through the kraft paper. When the film is pressed, the pressure distribution is uniform.

반면, 전량 수입에 의존하고 있는 크라프트 페이퍼는 일회용으로 재사용이 어렵고 종이재질로 지분 등 이물이 다수 발생되는 문제점이 있었다.On the other hand, kraft paper, which is entirely dependent on imports, has a problem in that it is difficult to reuse because it is disposable, and a large number of foreign substances such as stakes are generated as paper materials.

이에 따라, 한국등록특허 제10-0969705호 "연성인쇄회로기판(FPCB) 제조용 복합필름 및 이를이용한 연성인쇄회로기판의 제조방법"과 같이 크라프트 페이퍼를 대체하기 위한 기술개발이 지속적으로 이루어지고 있으나, 실리콘만으로는 이형성확보가 어렵거나, 크라프트 페이퍼를 대체할 수 있는 경도 및 열전도율 범위로 제조하기 어려운 문제점이 있었다.Accordingly, technology development to replace kraft paper is continuously being made, as in Korean Patent Registration No. 10-0969705 "Composite film for manufacturing flexible printed circuit board (FPCB) and manufacturing method of flexible printed circuit board using the same", There was a problem in that it was difficult to secure releasability only with silicon, or it was difficult to manufacture in a range of hardness and thermal conductivity that could replace kraft paper.

도 1은 본 발명에 따른 핫 프레스용 실리콘 패드를 도시한 단면도이며, 도 2는 본 발명에 따른 핫 프레스용 실리콘 패드의 다른 실시예를 도시한 단면도이고, 도 3은 본 발명에 따른 핫 프레스용 실리콘 패드의 또 다른 실시예를 도시한 단면도이다.1 is a cross-sectional view showing a silicone pad for hot press according to the present invention, FIG. 2 is a cross-sectional view showing another embodiment of a silicone pad for hot press according to the present invention, and FIG. 3 is a cross-sectional view for hot press according to the present invention It is a cross-sectional view showing another embodiment of the silicon pad.

도 1에 도시된 바와 같이, 본 발명에 따른 핫 프레스용 실리콘 패드(이하, 패드)는 회로기판 제조공정 중 핫 프레스를 통해 폴리이미드 필름과 같은 수지계열의 필름을 가열, 가압하여 절연수지층을 형성시키는 핫 프레스 공정에서 회로기판의 상,하부에 배치되는 실리콘 재질로 구성된 패드(10)로 회로기판의 상,하부에서 소정의 온도로 가열되어 가압하는 프레스를 대신하여 수지계열의 필름에 접하여 열과 압력을 전달하게 된다.As shown in FIG. 1, the silicone pad for hot press (hereinafter, the pad) according to the present invention heats and presses a resin-based film such as a polyimide film through hot press during the circuit board manufacturing process to form an insulating resin layer. In the hot press process to form, the pad 10 made of a silicone material disposed on the top and bottom of the circuit board replaces the press that is heated to a predetermined temperature from the top and bottom of the circuit board and pressurized, and comes in contact with the resin-based film to generate heat and heat. transmits pressure.

특히, 상기 패드(10)는 수직방향 열전도율을 기 설정된 범위로 조절하기 위한 열확산재(3)가 혼합되어 판상으로 경화된 실리콘 재질로 구성된 제1 레이어(1)를 포함하여 열전도율이 낮은 실리콘 재질로 인해 열이 균일하게 전달되지 못하거나, 특정 영역에 열이 집중되는 것을 효과적으로 방지하게 된다.In particular, the pad 10 is made of a silicone material with low thermal conductivity, including a first layer 1 made of a silicon material hardened into a plate shape by mixing a thermal diffusion material 3 for adjusting the vertical thermal conductivity to a preset range. This effectively prevents heat from being uniformly transferred or from being concentrated in a specific area.

또는, 보강재(4)가 제1 레이어(1)의 일면 또는 양면에 부착되거나, 보강재(4)가 배치된 상태에서 열확산재가 혼합된 액상 실리콘을 경화시켜 보강재(4)가 제1 레이어(1)의 일면 또는 양면에 일체로 형성되도록 제조될 수도 있다.Alternatively, the reinforcing material 4 is attached to one or both surfaces of the first layer 1, or the reinforcing material 4 is formed by curing the liquid silicone mixed with the thermal diffusion material in a state in which the reinforcing material 4 is disposed. It may be manufactured so as to be integrally formed on one or both sides of the.

또는, 복수 개의 제1 레이어(1) 사이에 보강재(4)가 배치되되, 제1 레이어(1)와 보강재(4)가 교번하여 적층되는 형태로 구성될 경우 패드(10)가 휘어지는 것을 보다 효과적으로 억제할 수 있다.Alternatively, when the reinforcing material 4 is disposed between the plurality of first layers 1, and the first layer 1 and the reinforcing material 4 are alternately stacked, the pad 10 is more effectively prevented from being bent. can be suppressed

도 3에 도시된 또 다른 실시예와 같이, 상기 패드(10)는 제1 레이어(1)의 일면 또는 양면에 실리콘 재질로만 구성되거나, 제1 레이어(1)와는 열확산재(3)의 혼합비율이 상이한 제2 레이어(2)를 더 포함하도록 구성될 수도 있다.3 , the pad 10 is composed of only silicon material on one or both sides of the first layer 1 , or the mixing ratio of the first layer 1 and the thermal diffusion material 3 . It may be configured to further include this different second layer 2 .
