Disco-DDS2300 Die Separators Die separator for high-precision DAF separation Φ300 mm SDBG SDTT Improves the cut quality of thin wafers with DAF In separation process for thin wafers with DAF (Die Attach Film), there are issues such as DAF burring forming on the cut surface when full-cut dicing is performed and pickup errors during die bonding.
Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a mill's energy budget. Overall energy use and media ...

Laser grooving kerf check function. During blade dicing, when low-k or copper layers are present in the street, which are difficult to cut, usually blade dicing is performed after laser grooving. Adding the kerf check function can optimize this process. The kerf check can be performed relative to the width or position of the detected groove/kerf.

1. Grinding Discs. It makes sense to talk first about grinding discs, also called "grit discs." These are the discs you need if you want to grind metal or stone. Each disc features an abrasive compound consisting of grains and a bonding agent. You can choose a higher or lower grit depending on how fine or coarse you want the abrasive grains ...
Application Laser grooving process. First, the DFL7161 rapidly makes two laser grooves in the dicing street - either "Pi Laser Grooving" or "Omega Laser Grooving"; then the wafer is blade-diced at standard speed. This application achieves excellent throughput yet greatly reduces or eliminates chipping, delamination and other cut-quality issues.
Grinding – Ex. 1-1 • You are grinding a steel, which has a specific grinding energy (u) of 35 W-s/mm3. • The grinding wheel rotates at 3600 rpm, has a diameter (D) of 150 mm, thickness (b) of 25 mm, and (c) 5 grains per mm2. The motor has a power of 2 kW. • The work piece moves (v) at 1.5 m/min. The chip thickness ratio (r) is 10.
The Center Offset Grinding of TAIKO Wafer. The TAIKO process is a wafer backgrinding method developed by DISCO. This process method leaves a ring (approximately 3 mm) on the wafer outer edge and thin grinds only the inner area of the backside wafer. By leaving this edge ring, it is possible to reduce the risks of wafer breakage or edge chipping.
The challenges of robot-based surface processing, such as deburring, polishing or grinding, lie in the compensation of tolerances, the programming of sensor-adaptive processes and the handling of complex geometries.Furthermore the integration of force-torque sensors, camera systems or special tools and the interaction with the robot requires special programming skills.
Grinding and Polishing Guide. Grinding should commence with the finest grit size that will establish an initially flat surface and remove the effects of sectioning within a few minutes. An abrasive grit size of 180-240 [P180-P280] is coarse enough to use on specimen surfaces sectioned by an abrasive wheel. Hack-sawed, bandsawed, or other rough ...
grinding. Each ground surface should have scratches that are clean-cut and uniform in size, with no evidence of previous grinding scratches. Cleaning before going to next stage grinding is always helpful. Grinding Mediums Grinding media are silicon carbide (SiC), aluminium oxide (Al 2 O 3), emery (Al 2 O 3-Fe 3 O 4), and diamond particles.
For example, when grinding with a 4" (101.6 mm) wide superabrasive wheel, the rest blade will generally work well at 30º. But with a wheel width of 6" (152.4 mm) or 8" (203.2 mm), that same angle may generate too much pressure toward the grinding wheel and cause chatter.
