In the back-end semiconductor packaging process, wafer dicing is a critical and core operation that divides an entire wafer into individual dies. With the continuous advancement of chip integration, ultra-thin wafer requirements, and the widespread application of third-generation compound semiconductors (such as Silicon Carbide [SiC] and Gallium Nitride [GaN]), traditional cutting methods are highly prone to causing catastrophic defects like micro-cracks and top chipping along the kerf edges. How can high-speed cutting stability be maintained under elevated spindle speeds while controlling die-fly and chipping tolerances within the micrometer (\u03bcm) range? Drawing upon advanced electroforming and resin-bond engineering technologies, the technical team at Honway Corporation has introduced its signature Dicing Blade series, custom-built for high-end semiconductors and electronic substrates. This article provides an in-depth exploration of the industrial application scenarios for Hub Blades (hard blades) and Hubless Blades (soft blades), while demystifying how the precise utilization of dressing boards can achieve the ultimate goal of minimizing top chipping dimensions.<\/p>\n\n
Precision diamond dicing blades are primarily divided into two main camps based on process applications: Hub Blades (hard blades) and Hubless Blades (soft blades). The primary physical differences between the two lie in the rigid support structure of the tool and the composition of the bonding agent, which directly determine their applicable material characteristics and debris evacuation trajectories.<\/p>\n\n
Hub Blades<\/strong> refer to blades where the ultra-thin cutting ring is integrally fixed to an aluminum alloy hub at the factory. This design provides exceptionally high axial bending rigidity, specifically engineered for the forced, highly rigid linear cutting of hard and brittle materials. Conversely, Hubless Blades<\/strong> are purely circular, ring-shaped thin blades that must be installed using the machine’s precision flange clamps. Their bonding agents possess moderate elasticity, allowing for micro-adjustments of stress during the high-speed cutting of hard, tough, or composite materials.<\/p>\n\n To address silicon wafer dicing, as well as third-generation semiconductors with extreme Mohs hardness and highly fragile cleavage planes (such as SiC wafers and sapphire substrates) or back-end packages, Honway Corporation has developed two flagship hub blade solutions based on the specific process stages:<\/p>\n\n Conversely, when encountering composite materials commonly found in modern advanced packaging or System-in-Package (SiP) configurations, the high rigidity of a hub blade can inadvertently trigger large-scale delamination defects. To address this, Honway introduces the HWES25 Package Dicing Blade (Hubless Type)<\/strong> solution:<\/p>\n\n On the production floor for wafer dicing and substrate processing, the metrics that engineers care about most are undoubtedly the size control of Top Chipping<\/strong> and Back Chipping<\/strong>. However, many process novices mistakenly assume that large edge chips on the wafer surface indicate a blade quality issue, completely overlooking the vital importance of the dressing board<\/strong>.<\/p>\n\n When a new dicing blade is first mounted onto the spindle, most of the diamond abrasives on the edge are encapsulated by an excess layer of bonding agent, meaning the cutting edge is not yet fully sharp or exposed. If wafer dicing is performed directly at this stage, excessive mechanical frictional stress will be pushed back into the silicon wafer, causing severe top chipping. The application engineering team at Honway Corporation points out that a precise “pre-dressing process” is an unskippable baseline in production:<\/p>\n\n
