Application of Right Angle Knife Repair
With the miniaturization of semiconductor devices, ultra-thin wafers, the popularization of compound semiconductors, and the increasing demand for high-precision grooves in advanced packaging, it is necessary to use a right angle knife for groove cutting in specific scenarios of semiconductor cutting to achieve vertical 90 ° sidewalls, low edge breakage, low damage, and high consistency in micro groove processing. However, during the machining process, the right angle cutter bears a large cutting force, and as the blade wears, it can lead to abnormal cutting of the right angle, directly affecting product quality and production efficiency, becoming a common problem in the industry.
In response to the common industry problem of the attenuation of the slotting right angle effect with the increase of the number of right angle knives, a precise tool repair process is used to restore the performance of the blade, extend the service life of the tool, reduce the cost of consumables, and ensure the stability of vertical 90 ° sidewall machining.
Process objective:Vertical 90 ° sidewall
Using equipment:AR9000W
Process background
With the miniaturization of semiconductor devices, ultra-thin wafers, popularization of compound semiconductors, and the increasing demand for high-precision grooves in advanced packaging, it is necessary to use a right angle knife for groove cutting in specific scenarios of semiconductor cutting to achieve vertical 90 ° sidewalls, low edge breakage, low damage, and high consistency in micro groove processing.
However, during the machining process, the right angle cutter bears a large cutting force, and as the blade wears, it can lead to abnormal cutting of the right angle, directly affecting product quality and production efficiency, becoming a common problem in the industry.
core pain point
The key technical challenges faced by slotting with right angle knives focus on the contradiction between tool life and processing quality: as the number of slotting knives increases, the cutting effect of right angle blades significantly decreases, and frequent tool changes can bring dual pressures of downtime losses and consumable costs.
High cost of consumables:As the number of blades increases, the slotting effect of right angle blades significantly decreases, and frequent blade replacement results in high consumable costs.
Significant production losses:The shutdown of tool changing directly affects production capacity, and the yield fluctuates significantly.
Unstable quality:The right angle effect decays with the number of cuts, resulting in poor product consistency.

Comparison of the effect before and after knife repair

Before repairing the knife
The right angle effect of the cutting track is abnormal (measured at 95.15 °/86.63 °), the slotting angle deviates from the target value, and the product yield decreases. It is necessary to frequently replace the blade to maintain the processing quality.

After repairing the knife
Restoring to the new blade level (measured at 90.47 °/92.00 °), the slotting angle is close to the ideal 90 °, allowing for efficient cutting and significantly extending the blade's lifespan while reducing consumable costs.
