Description

라우터 비트 {Router Bit}Router Bit {Router Bit}

본 고안은 라우터 비트에 관한 것으로서, 상세히 설명하면 PCB(Print Curcuit Board:인쇄회로기판) 드릴로 사용되는 라우터 비트에 관한 것이다.The present invention relates to a router bit, and more particularly, to a router bit used as a PCB (Print Curcuit Board) drill.

인쇄회로기판이란 첨단 전자기기(휴대폰, PC, 게임기, 반도체등)에 사용되는 각종 전자부품을 상호 전기적으로 연결해주는 핵심부품의 하나로서 배선회로면의 수에 따라 일반적으로 단면, 양면 다층PCB로 구분되며, 최근에는 반도체 실장용으로도 응용분야가 확대되고 있다. 전자기기의 소형화 추세로 PCB또한 고밀도화, 소형화, 박형화되어 PCB제조방법이 갈수록 정밀해야만 상기와 같은 추세를 맞출 수있다.A printed circuit board is one of the core parts that electrically connects various electronic components used in high-tech electronic devices (mobile phones, PCs, game machines, semiconductors, etc.), and is generally divided into single-sided and double-sided multilayer PCBs according to the number of wiring circuits. Recently, application fields have also been expanded to semiconductor mounting. Due to the trend toward miniaturization of electronic devices, PCBs are also densified, miniaturized, and thinned, so that the PCB manufacturing method is more accurate to meet the above trend.

라우터는 PCB제조공정중 일부에 해당되는 외형가공 공정에서 고객이 원하는 전자기기 크기로 PCB를 절단하기 위해 사용되는 고정밀도의 설비를 말하며, 비트라는 도구를 고속으로 회전(약33,000~38,000RPM/분)시켜 PCB를 절단하며, 상기와 같은 라우터 설비로 PCB외형 가공시 생산성을 위해 Work Panel을 여러장(제품에 따라 3~10매)을 겹쳐서 설계에 따라 절단작업을 하여 왔다.Router is a high-precision equipment used to cut PCB to the size of the electronic device desired by the customer in the external machining process, which is part of the PCB manufacturing process, and rotates the tool called beet at high speed (about 33,000 ~ 38,000RPM / min). The PCB is cut by the above-mentioned router facility, and the work panel is overlapped with several sheets (3 ~ 10 sheets depending on the product) for the productivity of PCB external processing.

상기와 같이 라우터설비는 스핀들에 비트를 장착시켜 고속으로 회전하면서 제품을 가공하기 때문에 고속회전에 따른 비트의 떨림현상이 발생하여 가공된 제품의 상판과 하판의 치수편차가 발생하고 또한 비트는 가공시 사용거리에 따라 날이 마모되어 치수편차가 발생하여 PCB불량을 초래하여 많은 과학자들이 이러한 문제점을 해결하기 위하여 다양하게 연구하여 왔다.As mentioned above, since the router equipment processes the product while rotating the bits at high speed by mounting the bits on the spindle, vibration of the bits occurs due to the high speed rotation. As the blade wears out according to the working distance, dimensional deviation occurs, which causes PCB defects.

Router jig is open,
