SynopsisSilicon carbide substrate is the cornerstone of the application of gallium nitride and silicon carbide in the third-generation semiconductor materials, while SiC materials are mainly used to epitaxially grow SiC epitaxial layers on conductive SiC substrates an.....
SynopsisThe SOI wafer is a sandwich structure similar to a sandwich (Sandwitch), with a total of three layers; including the top layer (device layer), the middle buried oxide layer (insulating SiO2 layer) and the bottom substrate (bulk silicon), applicable It has a wi.....
SynopsisPolyarylate (PAR )is a special polymer with thermotropic liquid crystal properties, which is formed by connecting aromatic rings through ester bonds. Because polyarylate has good heat resistance and electrical properties, it is mainly used for high temperature.....
SynopsisHigh-carbon chromium bearing steel is a large type of bearing steel, and it is the most commonly used steel for manufacturing bearings and bearing parts. The most commonly used high carbon chromium bearing steels are GCr15 and GCr15SiMn. The global High-.....
SynopsisThe robot servo system consists of three parts: a servo motor, a servo drive, and a command mechanism. The servo motor is used as an executive element in the control system, and the servo motor is used to drive the joints of the robot. The global Servo M.....
SynopsisBearing steel pipe refers to a seamless steel pipe that is hot-rolled or cold-rolled (cold drawn) for the manufacture of ordinary rolling bearing rings. The outer diameter of the steel pipe is 25-180 mm, and the wall thickness is 3.5-20 mm. There are two types.....
SynopsisThe grating ruler, also called the grating ruler displacement sensor (the grating ruler sensor), is a measurement feedback device that uses the optical principle of the grating. Grating rulers are often used in closed-loop servo systems of CNC machine tools, a.....
SynopsisVacuum evaporation, abbreviated as evaporation, refers to a process in which the coating material (or film material) is evaporated and gasified by a certain heating and evaporation method under vacuum conditions, and the particles fly to the surface of the sub.....
SynopsisThe liquid crystal material is a translucent dielectric material between the upper and lower glass plates of the liquid crystal panel, which functions as a shutter switch. Mixed liquid crystal means that due to the high performance requirements of liquid cryst.....
SynopsisHigh-frequency copper clad laminate refers to the working frequency above 5GHz, which is suitable for ultra-high frequency field, has ultra-low loss characteristics (ultra-low signal transmission loss), and can be applied to copper clad laminates in the microw.....
