Abstract

One of the early applications of lasers was marking electronics components. Today laser marking has found its way into a wide range of applications, from wafer marking at the chip scale package level to beer bottles and food package identifications, and to marking of the cloth buttons. In many cases, laser marking has become a standard manufacturing process. We will review the laser marking technology over the last four decades. This would include the review on evolution of the different laser technologies and beam delivery systems used in various laser-marking systems for the past 40 years. Finally, the latest laser marking technologies will be presented and future directions be discussed.
