Techniques or processes for providing markings on products are disclosed. In one embodiment, the products have housings and the markings are to be provided on sub-surfaces of the housings. For example, a housing for a particular product can include an outer housing surface and the markings can be provided on a sub-surface the outer housing surface yet still be visible from the outside of the housing. Since the markings are beneath the surface of the housing, the markings are durable.

A process of forming an identification marking within article formed from an at least partially optically transparent material for identification and validation, said process including the steps of (i) forming an indicia with an at least partially optically transparent material by way of subsurface laser engraving (SSLE); and (ii) forming a plurality of defects within or adjacent indicia within said at least partially optically transparent material resultant of the step of forming the indicia and from localized heating and irregularities in said at least partially optically transparent material, wherein said plurality of defects forms said identification marking

A system and method for performing laser marking may include identifying an event performed by a laser marking system. A laser marking unit may be driven to mark the feature on the part. The part may be illuminated with a visible illumination signal to indicate an occurrence of the event in response to identifying the event.

Flame retardant thermoplastic compositions that are capable of being used in a laser direct structuring process. The compositions include a thermoplastic resin, a laser direct structuring additive, and a flame retardant. The compositions offer flame retardant characteristics while also substantially maintaining the mechanical properties of the base thermoplastic resin, such as the impact strength and/or HDT of the composition. The compositions can be used in a variety of applications such as personal computers, notebook and portable computers, cell phone and other such communications equipment.
