An effective way to identify products in production and logistics areas is to mark them directly with two-dimensional codes, such as Data Matrix codes. These codes, which are applied to the product or workpiece with direct part marking (DPM), allow you to identify individual production steps and data at any time. It is then possible to track the entire service life of a product.
DPM codes are primarily used in mechanical engineering applications and in the electronics and automotive industries. The codes are placed on printed circuit boards, as well as metal and plastic components. Laser etching, dot peen marking, and ink jet marking are among the most common methods of attaching codes directly to parts.
