When Laser Cutting Technology Meets PCBs: Enhancing Quality and Efficiency for Automotive Applicatio

Printed circuit boards (PCBs) are widely used in the automotive industry in vehicle electronic devices, sensors, lighting systems, and many other automotive applications. In applications that require high safety, PCBs must meet high quality standards, so we must be cautious about every detail of the PCB production process.

Wuhan Sintec Optronics Co., Ltd., with its rich laser expertise and automotive industry experience, performs outstandingly in PCB laser cutting.

First of all, laser cutting PCBs is different from using machining or stamping for cutting, as laser cutting does not leave dust residues on the PCB, which will not affect subsequent use, and the mechanical stress and thermal stress introduced to the components by the laser are negligible small and the cutting process is very gentle.

Secondly, laser technology can meet cleanliness requirements. Through Sintec optronics technology, PCB substrates can be non-carburized and non-discolored processed to produce PCBs with high cleanliness and quality. In addition, Sintec optronics has also designed relevant functions in its products to prevent failures during the cutting process. Therefore, users can achieve extremely high yield in production.

In fact, by adjusting the parameters, the same laser cutting tool can be used to process various materials, such as standard applications (such as FR4 or ceramics), insulated metal substrate (IMS) and system-in-package (SIP). This flexibility allows PCBs to be applied to various scenarios such as cooling or heating systems for engines, chassis sensors, etc.

There are no limits in design for contours, radii, labels or other aspects of PCBs. Through full circumferential cutting, PCBs can be placed directly on the table, greatly improving space utilization efficiency. Compared with mechanical cutting technology, laser cutting of PCBs can save more than 30% of materials. This not only helps reduce the cost of producing special-purpose PCBs, but also is conducive to building a friendly ecological environment.

Sintec Optronics laser systems can be easily integrated with existing manufacturing execution systems (MES). The advanced laser system ensures stability in the operation process, while the automation characteristics of the system also simplify the operation process. With higher output laser sources integrated, current laser machines can now fully compete with mechanical systems in cutting speed.

In addition, the operating costs of laser systems are low, as there are no wear parts (such as cutters). This avoids the costs of replacing parts and downtime caused.

The application fields of laser are very wide. In addition to being used for substrate cutting, it can also be used for individual material layer marking, drilling or engraving.
