본 발명은 이동단말기에서 사용하는 인쇄회로기판에 관한 것으로, 특히 이동 단말기의 소형화에 적당하도록 인쇄회로기판에 진동모터와 스피커를 삽입시킬 수 있는 홀을 만들어 구비시켜 이동단말기의 크기를 줄이는 데 적합한 이동단말기용 인쇄회로기판 장치에 관한 것이다.The present invention relates to a printed circuit board used in a mobile terminal, and in particular, a hole suitable for miniaturization of a mobile terminal is provided by making a hole for inserting a vibration motor and a speaker in the printed circuit board to reduce the size of the mobile terminal. A printed circuit board device for a terminal.

일반적인 인쇄회로기판(印刷回路基板 printed circuit board : PCB)은 집적 회로, 저항기 또는 스위치 등의 전기적 부품들이 납땜되는 얇은 판을 의미한다.A general printed circuit board (PCB) refers to a thin plate on which electrical components such as integrated circuits, resistors, or switches are soldered.

대부분의 컴퓨터에 사용되는 회로는 이 인쇄 회로 기판에 설치된다. 보통의 인쇄 회로 기판이 만들어지는 순서는 절연체인 에폭시 수지 또는 베이클라이트 수지로 만든 얇은 기판에 구리박을 붙인 후에, 계속하여 구리박으로 남아 있기를 원하는 회로 배선에는 레지스트를 인쇄한다. 그리고 구리를 녹일 수 있는 식각액에 인쇄된 기판을 담그면 레지스트가 묻지 않은 부분은 녹는다. 그 후에 레지스트를 제거하면 구리박이 원하는 형태로 남아 있다. 부품을 꽂아야 하는 부분에는 구멍을 뚫고 납이 묻으면 안 되는 곳에는 푸른색의 납 레지스트를 인쇄한다.Circuits used in most computers are installed on this printed circuit board. The order in which a normal printed circuit board is made is to attach copper foil to a thin substrate made of an epoxy resin or a bakelite resin, which is an insulator, and then a resist is printed on the circuit wiring which is desired to remain copper foil. Subsequently, the printed substrate is immersed in an etchant that can dissolve copper, and the non-resist-free portion melts. The resist is then removed to leave the copper foil in the desired form. Drill a hole in the part where the part should be inserted and print a blue lead resist where it should not be leaded.

한편, 이동단말기서의 메인보드도 인쇄회로기판으로 구성되는 것으로, 중앙 처리 장치(CPU), 메모리 등 주요 부품 간의 연계를 주관하는 기판으로서 CPU 소켓이나 칩 세트, ROM 등을 갖추고 있다. 이동단말기에서의 성능을 확인할 경우 PCB로 제조되는 메인보드의 설계 내용도 이에 못지 않을 만큼 중요한 요소이다. 메인보드의 중심적인 역할은 칩 세트라는 대규모 집적 회로(LSI)가 담당한다. On the other hand, the main board of the mobile terminal is also composed of a printed circuit board, and has a CPU socket, a chip set, a ROM, and the like as a board that manages the linkage between main components such as a CPU and a memory. When checking the performance of the mobile terminal, the design content of the main board manufactured by the PCB is equally important. The central role of the motherboard is played by a large integrated circuit (LSI) called a chip set.
