Semiconductors and small electronic components are usually produced in very large quantities. Economic mass production is only possible through fully automated processes. The small components often have to be provided with much information. This information must be flexibly and extremely quickly applied to the components.
By using a laser system with a galvo head for very fast deflection of the laser beam and a partially or fully automated solution, the high requirements can be met. The applied marking is resistant, durable and perfectly readable.
A laser system is also used for special test procedures of microchip testing, also called decapping.
Decapping a microchip into a process of removing the protective coating of a microchip so that the actual chip itself is revealed for visual inspection of the microcircuits. This process is typically performed to debug a manufacturing problem with the chip or possibly copy information from the chip.
