basic information
◉ The rough particle surface of polycrystalline diamond has many contact points between the diamond particles and the workpiece, achieving a high material removal rate. ◉ The compressive strength and impact strength are far below that of single crystal diamond. In the lapping process, polycrystalline particles are broken down under pressure, revealing new sharp cutting edges. ◉ Since they are destroyed in their original shape, a more delicate finish becomes possible. ◉ Polycrystalline diamonds do not have cleavage planes, so they do not break like single crystal diamonds. Therefore, there is no deformation beneath the surface. ◉ Ideal for high-performance lapping and polishing. ◉ The particle size distribution is strictly controlled to prevent the generation of oversized particles. ◉ A stable slurry improves process stability. ◉ All components are environmentally friendly, reducing disposal costs. ◉ Cleaning after lapping/polishing is easy. ◉ Qual Diamond's innovative formulation can maintain an environment from -20°C to 50°C.

Applications/Examples of results
Solutions for the Semiconductor Industry: Semiconductor technology is rapidly advancing due to new wafer manufacturing techniques, simulation, MEMS, and advancements in nanofabrication. In the semiconductor industry, the thinning of silicon wafers is achieved through fine grinding and polishing. Additionally, other electronic device manufacturing technologies, such as printed circuit board manufacturing, are also experiencing significant growth, but challenges related to processing and thickness quality remain a major concern for the industry. Hydroqual Mono slurry or Hydroqual Poly D slurry can be used at each stage of the polishing process for electronic and semiconductor applications. In the thinning of silicon wafers, the size distribution of diamonds becomes crucial to maintain consistent edge-to-edge flatness and a good aspect ratio. Metal structure polishing solutions: Diamond slurry has proven to exhibit excellent performance in addressing surface imperfections caused by other abrasives. New submicron-level diamond slurries and new microscopy techniques are leading metal structure inspection technology into a new frontier.
