Laser Scribing and Marking

Laser scribing and laser marking are highly precise methods for surface refinement of heat sinks in power electronics. Laser scribing uses a laser to engrave fine patterns onto the surface of the heat sink, enabling electronic components to be soldered directly onto copper or gold-plated (NiAu) heat sinks. This technique optimizes thermal coupling and improves the mechanical stability of components. The precise control of the laser allows the creation of complex designs with high repeatability, increasing production efficiency and allowing flexible adaptation to specific requirements. Laser marking also allows for permanent markings such as serial numbers, logos, or technical information to be applied to heat sinks without affecting the surface structure or functionality. This is particularly advantageous for demanding applications requiring precise identification and traceability. The combination of laser scribing and laser marking opens up numerous possibilities for optimizing functionality, quality, and customization of heat sinks in modern power electronics.

Screen Printing

Screen printing is a proven method for surface refinement of heat sinks in power electronics, allowing precise and repeatable patterns, inscriptions, and markings to be applied. A special paste is printed onto the heat sink surface through a fine mesh screen, ensuring even and sharp reproduction of even complex designs. Screen printing is ideal for marking and labeling heat sinks with logos, technical information, or color codes without impairing the thermal and electrical properties of the components. Additionally, this method offers high resistance to mechanical and chemical stresses, ensuring the durability of markings even under demanding operating conditions. Thanks to its flexibility in materials and colors, screen printing allows for tailored adaptation to specific design requirements and supports the branding of electronic products. This makes screen printing a cost-effective and versatile solution for functional and aesthetic refinement of heat sinks in modern power electronics.
