Fio de diamante serra cortada ímã NdFeB

Diamante fio loop serra corte ímã NdFeB ímãs de neodímio, também conhecidos como ímãs NdFeB, são cristais tetragonais formados pelo neodímio, ferro, and boron (Nd2Fe14B). This type of magnet is the second most magnetic permanent magnet after absolute zero holmium magnet today, and it is also the most commonly used rare earth magnet. NdFeB is divided into two types: sintered NdFeB and bonded NdFeB. Bonded NdFeB has magnetism in all directions and is resistant to corrosion; The sintered NdFeB is easy to corrode, e...

Direção de desenvolvimento de equipamento de corte de wafer de silício com fio diamantado

1) High line speed and high production capacity support the reduction of single GW investment According to the theory of fracture mechanics and the properties of silicon materials, when the maximum cutting depth of diamond abrasive grains is greater than the critical cutting depth of silicon materials, the transition from plastic cutting to brittle fracture cutting will occur. Portanto, within the allowable range of the diamond wire load, appropriately increasing the steel wire speed in the multi-wire cutting process is beneficial...

Fluxo de processamento de lingotes de silício na indústria de semicondutores

Na etapa de preparação do wafer de silício monocristal, the silicon ingots need to be processed into raw silicon wafers or barewa-fers with high surface accuracy and surface quality to prepare for planarization for lithography and other processes in the first half of the IC process. Ultra-smooth and damage-free substrate surface are required here. For silicon wafers with a diameter of ≤200mm, the traditional silicon wafer processing process is: single crystal growth → cropping → outer diameter barrel grinding → flat edge or V-groove treatment...
