Laser marking of circuit boards

Smartphones, computers, electric cars – just pay attention to our real lives and feel the enormity of the electronics industry. And it's still evolving at a rapid pace. This would not have been possible without laser technology. Laser technology enables the electronics industry to have the necessary efficiency in the production process. Laser marking of electronic components plays an important role in this. In the electronics industry, productivity is a top priority. When ultra-small, sensitive parts need to be permanently marked, lasers are a must.

Laser markers are the first choice for marking sensitive electronic components. Thanks to the targeted energy input and stable laser characteristics, process reliability is guaranteed, even for different component materials. If these parts are exposed to harsh conditions, the markings must be durable. TRUMPF laser markers offer the flexibility in wavelength, pulse duration and power classes required for laser marking of electronic components. Durable and highly available. This ensures productivity in the electronics industry.

Efficient: TRUMPF laser markers help you significantly reduce processing times.

Versatile: roughening, cleaning, texturing: the laser marking machine also prepares the material for the connection.

Gentle on materials: Sensitive electronic components are not stressed during laser marking; Less heat gets in.

Flexible: Whether it's a small size, a combination of different materials or a delicate connection – lasers enable a wide range of component designs.

Application examples

Laser marking of printed circuit boards (PCBs).

Every electronic product is equipped with a printed circuit board (PCB). Traceability is particularly important here. Because in the event of a manufacturing defect, the entire batch can be quickly identified by marking. When marking text, serial numbers, barcodes or 2D codes on printed circuit boards, a safe and efficient process is required due to the tight space and sensitive materials: TRUMPF laser markers achieve reliable and fast laser marking with high pulse peak power and excellent focusability.

Diode laser marking

Semiconductors are getting smaller. If you want to mark semiconductors, you need to make sure that the marking content is clear and machine-readable. In addition to this, the periphery must be undamaged during marking. Pulsed lasers are ideal for this type of task. Even for microcomponents, pulsed lasers can be processed quickly and precisely.

Laser marking of flame-retardant synthetic materials

Flame-retardant synthetics are mostly used in electronic components, such as switches. The decisive factor for high-quality laser marking of components made of flame-retardant synthetics is the appropriate wavelength for the thermal modification of the synthetic. Marking with a UV laser marker (using ultraviolet wavelengths) is better absorbed by flame-retardant synthetics. Marking is produced by a photochemical reaction on the surface of the part – the marking quality is high.
