Used BLANCHARD 42HD-84 #9112760 for sale

BLANCHARD 42HD-84 is a state-of-the-art wafer grinding, lapping, and polishing equipment that is designed to quickly and accurately finish semiconductor substrates. This system is capable of producing extremely precise results, making it ideal for the finishing of high-tolerance and high-precision components. The machine features a 42-inch capacity grinding wheel that is capable of removing microscopic levels of material from wafers with one pass. The wheel is powered by a robust, high-torque motor, which ensures that the wheel is always producing even and consistent grinding performance. The grinding wheel is enclosed in a safety enclosure to protect the operator from any airborne particles and debris generated during operation. The grinding wheel also features a unique water cooling unit, which helps to dissipate the heat generated during the grinding process and ensure that the wafers do not become damaged due to excessive temperature. This cooling machine also helps to extend tool life, reduce particle contamination, and keep particles from becoming imbedded in the silicon wafer. Once the wafer has been ground, the lapping and polishing process begins. This process consists of two separate operations. The first uses a specialized diamond scattered with abrasive particles to smooth and polish the wafer, while the second takes advantage of a variable speed drive motor to deliver an even and consistent polishing effect. This ensures that the lapping and polishing results are as precise as they can be. Finally, the finished wafer is inspected, cleaned, and packaged for shipping. An automated vision tool helps to quickly and accurately inspect the wafer for any damage or unevenness. This asset is designed to perform a virtual digital inspection of the wafer surface on a microscopic level, helping to ensure that the finished product meets customer requirements. The model is also capable of detecting any defects that may have occurred during the lapping/polishing process. Overall, 42HD-84 is an impressive wafer grinding, lapping, and polishing equipment that can be used to accurately and quickly finish semiconductor substrates. With its powerful motor, temperature control features, and automated vision system, this unit is capable of producing extremely precise results to meet customer requirements.
