When it comes to dicing hard and brittle materials, the type of dicing saw selected is critical to the outcome of the project. There are several types of dicing saw available for various dicing projects. When selecting the right dicing saw blade, a number of factors should be considered. These factors include the blade quality, blade life, and rigidity of the blade’s material, as well as how these components will react with the material being diced. The type of dicing saws will dictate the cutting speed, performance, and surface finish.
Dicing Saw Considerations
Before selecting a dicing saw for a particular project, providers must consider factors such as:
- Depth of the required cuts
- Type of material being cut
- Needed quality of the cut
- Required production output
- Equipment and speed/RPMs used
Dicing Saw Bonds
The primary variation among dicing saw types is the type of bond used to manufacture the blade. Dicing saw blades are primarily constructed of fragments of diamond or cubic boron nitride (CBN), as well as metal dust. Diamond or CBN have a critical function as the abrasive that performs the dicing job. This is because diamond and CBN are among the most durable materials known to man. The abrasive and metal dust may be compressed at high temperatures to form a strong, durable dicing saw. The type of dicing saw bond will vary based on components such as the type of metal used and the size of the diamond or CBN.
Types of dicing saw bonds include:
- Resin bond: Typically more forgiving and freer cutting. These dicing saw blades are recommended for projects in which surface finish and cut quality are most important.
- Sintered (metal bond): Provide exceptional consistency and long life. These blades are recommended for larger blade exposures and very straight cuts.
- Hybrid bond: The speed and finish of a resin bond, in addition to consistency, long life, aggressiveness, and exceptional performance.
- Hubless nickel bond: Ideal for cutting thin substrates and wafers, as they maintain exceptional sharpness and form with minimal chipping.
- Hubbed nickel bond: Pre-mounted on a hub, this dicing saw blade provides a low wear rate and excellent cut quality. These saws are best for dicing silicon as well as III-V materials.
Selecting a Dicing Saw
All components of a dicing project should be considered carefully when selecting a dicing saw blade.
