Used STRASBAUGH 6C #9298685 for sale

STRASBAUGH 6C is a CNC-based wafer grinding, lapping, and polishing equipment, manufactured by STRASBAUGH Technologies Incorporated. It is a highly efficient and cost-effective production machine developed and designed to meet the necessary requirements of the semiconductor industry. Developed over thirty years ago and refined ever since, 6C can be used in a wide range of manufacturing processes and is capable of grinding and polishing both single and double-sided wafers. STRASBAUGH 6C system encompasses a series of clamping, grinding, lapping, and polishing spokes that are affixed to a rotary shaft mounted on a sturdy support frame. All equipment is controlled and driven by powerful drive motors that can handle a variety of wafer sizes, thicknesses, and production rate requirements. The clamping spokes, located at the center of the rotary shaft, secure the wafers in place while the grinding, lapping and polishing spokes rotate around the outer edge of the shaft, in continuous motion. For single-sided wafer grinding, a transparent polymer abradant pad is used over the grinding spoke and allows for a complete, uniform blend of the surface with minimal impact to the existing pattern. For double-sided grinding, a rotary grinding head with a diamond-tipped abrasive disc is used for precision grinding on both sides simultaneously. The lapping and polishing operations are designed with tight tolerances and are capable of producing excellent mirror-like finishes. The rotary lapping enclosure houses a series of compact driven spindle units, each composed of precision-balanced stainless steel plates. The spindle units contains several diamond tools that, when activated, are driven by a high pressure coolant flow. Depending on the choice of abrasives, these controlled coolant jets help to slowly, but continuously, scale down the wafer surface, leaving a perfectly flat surface with excellent surface finish. Finally, a specially designed polishing spindle unit is used to polish further, producing a highly reflective and smooth mirror-like finish. 6C is characterized by its low power consumption and excellent levels of accuracy, speed and repeatability. With the addition of automation and recirculating coolant systems, STRASBAUGH 6C unit can provide for even greater efficiency in production and repeatability of results. This machine has become a favorite of the semiconductor industry due to its robust design and ability to provide consistent robust performance in most demanding applications.
