Laser Depaneling for Automotive Applications from LPKF


TUALATIN, OR — Vehicles con- tain many PCBs — in the onboard electronics and sensors, in the lighting system, in previ- ously purely mechanical systems such as seat or mirror adjusters, and in many other places. Especially for safety-rele-


vant applications, a printed cir- cuit board has to meet high qual- ity standards. Here, it is essen- tial that the PCB always works reliably during operation. To ensure this, every single detail of PCB production must be just right. With extensive expertise in laser technology and experi- ence in the automotive industry, LPKF has these requirements in mind when it comes to depanel-


ing and allows this know-how to flow continuously into product development. During depaneling, the last


step in the process of manufac- turing PCBs, the boards in a panel are singulated. Unlike mechanical depaneling processes such as milling or punching, the laser process leaves no dust on the populated boards, so later functionality in use is not jeop- ardized. The depaneling process is gentle; the mechanical and thermal stresses introduced into the components by the laser are negligible. Standards pertaining to technical cleanliness, such as VDA 19/ISO 16232, can be met with laser technology.

The CleanCut technology


from LPKF enables substrate processing free of carbonization and discoloration. The result is high-quality printed circuit boards with maximal technical


ceramics all the way to insulated metal substrates (IMSs) and sys- tems-in-packages (SiPs). The pinpoint control of the


laser beam results in unsur- passed cut precision and extremely narrow cutting chan- nels. With a full perimeter cut, the individual printed circuit boards can be positioned on the panel without large breakout clearance channels for optimal space utilization. Thus, materials savings of

cleanliness. The process thus provides a preventive measure against potential component fail- ure during use. Especially for sensitive com-


ponents such as sensors, the yield for users is thus particular- ly high. Laser-processable mate- rials range from standard appli- cations such as FR4, flex, or


more than 30 percent in compar- ison with mechanical depaneling processes can be realized. This paves the way for achieving cost efficiency in the production of application-specific printed cir- cuit boards and has positive effect on the ecological footprint. Contact: LPKF Laser &
