Electroformed hub dicing blade

Details:
Electroformed hub dicing blade is made by using an ultra-thin diamond wheel and a high precision aluminum alloy hub.

Applications of hub dicing blade:
cutting Silicon Wafers, copper wafer, IC/LED Packages, Compound Semiconductor Wafers (GaAs, Gap),Oxide Wafers (LiTaO3), Optical Glass


The features of hub type dicing blade:
* improving balance between blade life and processing quality (in particular backside chipping)
* Strengthens rigidity, Reduction in wavy cutting and blade wear under high load conditions
* precise control of diamond grit size, diamond concentration, and nickel bond hardness to reduce splitting on the edges
* Realizes high speed wafer cutting after laser grooving.
