OBJECTIVE

Develop a process to dice lithium niobate  (LiNbO3) bars.

SPECIFICATIONS

Max. Edge Chipping:  20mm

OUTLINE

Initial testing was conducted with a resin-bond blade, but chipping at the entrance and exit corners exceeded specification.

The required edge quality was achieved by reducing wheel grit size and concentration. Switching to a metal-bond also reduced blade wear. The final test parameters are shown in Table 1:

RESULTS

A total of (44) parts were generated and randomly inspected:
