532nm 녹색 레이저 에칭 PCB 회로 기판

동박 적층판은 PCB의 기본 소재입니다. PCB의 전통적인 생산 공정에서 처리 기술은 화학적 에칭에 의해 동박판 위의 배선도를 제외하고 주로 동박층을 제거하고 세척 및 탈검과 같은 추가 단계가 추가됩니다. 드릴링, 구멍 금속화 및 코팅이 중간에 있기 때문에 전체 공정은 공정 주기가 길고 레티클에 의해 제한되어 정밀도가 낮고 환경 오염이 쉽습니다.

단면에서 양면으로, 단층에서 다층으로 PCB 기판이 발전함에 따라 Rigid 기판, Flexible 기판 및 Rigid-Flex 기판이 있으며 고정밀, 고밀도, 고밀도로 지속적으로 발전하고 있습니다. 신뢰성과 고성능. 또한 점점 작아지고 있으며 전통적인 제조 공정의 섬세함과 생산 능력이 분명히 부족하여 대량 가공 및 생산에 도움이 되지 않습니다.

Laser processing gradually replaces traditional processing technology with high efficiency, high consistency and high precision, and also has important applications in PCB circuit etching. The 532nm green laser can be used to directly complete the etching without a mask, and it can be done in one step, avoiding the pollution and cumbersome operations of the traditional chemical etching method. The processing mechanism is to act on the copper layer of the copper clad laminate by a high-energy density laser beam, so that it can be quickly evaporated and vaporized to achieve the purpose of removal, so as to produce the required circuit pattern.

The excellent beam quality (M2<1.2) and the easy focusing characteristics of the 532nm green laser make the spot size of the output laser beam in the order of microns, which can match the processing requirements of complex PCB boards and fine circuits, bringing higher processing. ; High stability can keep the etching quality more consistent and the appearance is good. At the same time, the single-photon energy of the 532nm green laser is high, and the copper material has a good absorption peak in the 355nm band compared to other bands, supplemented by a narrow pulse width of about 25ns, the thermal effect during processing is small, and the heat affected zone is small, even if the In the face of flexible circuit boards (FPC) based on materials with high thermal sensitivity such as PI film, it also has a very good processing effect, and the "cold" processing effect is worthy of the name.

Today, 532nm green lasers are widely used in circuit board manufacturing. Different powers have different divisions of labor. For example, low power of 3-5W can be used for high-quality marking of PCB boards or FPC flexible boards, and higher power can be used for punching holes. (through holes or blind holes), cutting, etc., are reliable tools for improving quality and efficiency in the production process of circuit boards.
