Laser Marking in Electronics Industry
Even in the Smallest Areas
Electrical products usually bear various labels and markings, they are required for good usability and contain type- and security information, serial numbers and traceability codes. Solid state and CO2lasers will produce durable laser markings on commonly used materials even on the smallest areas. For instance, a perfectly legible 2D matrix code will fit within an area of less than 1 mm x 1 mm.
Laser marking of polymers relies on carbonization or foaming processes caused by laser beam absorption. For backlit parts the laser selectively removes specific lacquer layers from multilayer-coated transparent bodies.
For metal housings annealing is used in most cases. Annealing produces durable laser markings with perfect surface quality without adding any undesirable substance.[/vc_column_text][vc_single_image image=”2429″ style=”vc_box_outline” border_color=”blue” title=”Laser Marking of Components for Electrical Installation”][vc_column_text]
- Dark and light markings on differently colored parts.
- Data-matrix codes by color exchange.
