μMark

The μMARK is a unique computerized laser system for the marking of Chip Size Packages (CSP) in a wafer form. The wafer is automatically aligned (manual alignment is also possible) for an accurate and reproducible marking. The whole process is controlled and monitored by both hardware and software. The mark layout is designed with a built-in graphic editor. The mark may include characters, graphics, logos and “leg-1” dot. The system may use either a CO₂ or a Nd:Yag laser.
