ZH05 Series

Availability: Product not in stock!

Provides stable processing through high-accuracy concentration control
Electroformed bond

Applications: Silicon wafer, Compound semiconductor wafers (GaAs, GaP, etc.), Oxide wafers (LiTaO3, etc.), etc

Newly developed grit concentration control technology has made possible five distinct levels of grit concentration. This wider range of choices offers improved balance between blade life and process quality (in particular, backside chipping).

  • 5 grit concentration levels support diverse applications.
  • The ZH05 Series offers shorter precut times and lower chance of blade breakage due to flying die

Product Classification

Concentration range

During dicing, concentration affects both the speed of blade wear and the size of chipping. By selecting precisely a concentration* that is appropriate to the application, both wear speed and process quality can be made more stable and consistent.

*Concentration refers to the percentage of diamond grit in the abrasive portion of the blade. For example, a concentration level of 100 indicates 25 % diamond grit by volume.



Experimental Data

By increasing the concentration options for ZH05, it is possible to precisely respond to customer needs. It also has the potential to shorten the precut time.

To use these DISCO blades and wheels (hereafter precision tooling) safely...
Please read carefully and follow the instructions below to prevent any accidents or injuries:

  • USE a safety cover (nozzle case, cover), equipped as a standard accessory, to avoid injury.
  • DO NOT EXCEED the specified rpm limit indicated on the precision tooling.
  • FOLLOW the instruction manual of the equipment to mount the precision tooling properly.
  • DO NOT DROP OR HIT the precision tooling. This may cause breakage or injury.
  • Always CHECK the precision tooling for chipping or any other damage before starting to use it. DO NOT USE the tooling if there is any damage.
  • READ the operation manual of the cutting/grinding equipment before use.
  • DO NOT USE the precision tooling with modified or customized equipment.
  • DO NOT USE precision tooling that has a different size from the one recommended for your equipment.
  • DO NOT USE the precision tooling for any other purpose than grinding, cutting, or polishing.
  • Always USE water or coolant to prevent precision tooling damage.
