• Grintimate GRC-series, a good partner for Semiconductor industries (20210528)

  With the scale of 5G and the rise of electric vehicles industries, Silicon wafers, gallium nitride GaN, and silicon carbide (SiC) applications are growing.  The pre-process of wafer grinding is including lapping and grinding for rough grinding or rough polishing followed by Chemical Mechanical Polishing(CMP).  Both have advantages and disadvantages.  The first one causes small scratches on the surface, poor quality & inefficiency.  The last one causes the extreme inefficiency & bad roughness.  Therefore, GRINTIMATE Horizontal Hydrostatic Rotary Surface Grinder (GRC-series) has been launched and presented at 2020 SEMICON TAIWAN with enthusiastic response.

  GRC-series are equipped with a hydrostatic bearing spindle and hydrostatic rotary worktable, with characteristics of high rigidity and high vibration resistance, non-friction and non-stick slip , supporting an eccentric stress and high centrifugal force processing.  The spindle and work table run-out can easily reach <1μm.  The rotary table maintains a load capacity of >10,000kg.   The stability of hydrostatic can effectively improve scratches and grinding efficiency, maintain long service life, greatly lower maintenance costs, and enhance machine stability during operation, which is very suitable for hard and fragile material processing, such as SiC, Alumina, Zirconia, Porous Ceramics and Chuck Table and etc.

• Grintimate hydrostatic grinder is the best for production quality improvement (20210528)

  Over the past 30 years, based on the beneficial comparation, division of labor and specialization in global supply chain, which allows the continued innovative development worldwide in Semiconductor industry. With this architecture, the US is committed to the range of IC design and sales, Japan and Netherlands are dedicated in IC materials and equipment while Taiwan, South Korea, and China are focus on production and manufacture. In order to enhance the competition in Taiwan, the Grintimate is dedicated in developing high-precision, high-quality, low vibration, environmentally machine tools to keep up with the growing of semiconductor industry for a wide range of processing requirement. At the moment, the global semiconductor industry competition has been turning white-hot situation, apart from production processing, yield rate, or production capacity, and the newly use of material is critical. The material revolution caused by the third generation of semiconductor industry, which is mainly with GaN and SiC materials. In order to provide a wide range of materials in grinding application, with the exclusive hydrostatic spindle technology, which could enhance the stability and rigidity of machine, providing the optimized processing equipment for clients.

  The most important core technology of Grintimate is with the exclusive hydrostatic spindle technology, all the products are equipped with a hydrostatic spindle.  In order to widely applied in the gradually growing industries for high-precision processing, such as semiconductor, electric automobile, automation intelligence, and aerospace industries, etc.  The wheel spindle of plunge type cylindrical grinder (CDC-series) and angular type cylindrical grinder (CAC-series) features high-rigidity, high vibration resistance, high load-capacity, and temperature rise resistance, the spindle run-out can easily reach < 1.0μm, perfectly on heavy cutting efficiency and mirror surface performance.  The CAC series has excellent precision not only on O.D. surface, taper surface, forming O.D. surface, R surface, grooved surface, and end-face surface, but also be widely used in target and Sapphire crystal column grinding.
