Laser Bar Stacking

Applications

Stacking or unstacking laser dies for facet coating

Prior to facet coating laser bars are being piled up into stacks. The so formed large area of die facets can easily be transferred to coating chambers and efficiently coated.

Both the grade of the laser and the yield of the laser chip production are depending on the quality of the coating. In turn the quality of the coating is proportional to the precision of the stack. A high precision stacking equipment therefore is mandatory for a reliable and cost effective laser bar production.

The ideal machine for this task is the ficonTEC StackLineā„¢.
