NdFeB permanent magnet material overview

NdFeB permanent magnet material overview 1. NdFeB magnets introduction NdFeB magnets, also known as NdFeB magnets, are tetragonal crystals formed by neodymium, iron, and boron (Nd2Fe14B). NdFeB is the third-generation rare earth permanent magnet, which is called “Magnetic King” because of its excellent performance. High-performance NdFeB refers to sintered NdFeB permanent magnet materials whose sum of intrinsic coercivity (HcikOe) and maximum magnetic energy product ((BH)maxMGOe) is greater than 60. 2. NdFeB permanent magnet material classification NdFeB permanent magnet material is the representative of rare [...]

A simple understanding of semiconductor silicon wafers

A simple understanding of semiconductor silicon wafers      一， Introduction to Semiconductor Wafers The research of semiconductor originated from the research of solid state physics and electronic science. In 1938, Shaw’s paper “Rectification at the Metal-Semiconductor Interface” was the first to link the fundamental research of solid state physics with the performance of semiconductor components. At the end of 1947, the first transistor was born at Bell Labs. Early research on solid-state physics was based on germanium crystals as transistors, but [...]

Processing flow of single crystal silicon ingots in the semiconductor industry

Processing flow of single crystal silicon ingots in the semiconductor industry In the single-crystal silicon wafer preparation stage, the silicon single-crystal 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 → [...]

How do manufacturers test tires?

How do manufacturers test tires? Tire design determines the relevant basic indicators of the tire (such as specification, size, bearing capacity, pattern, etc.), on this basis, tire R&D engineers select the appropriate tire structure, frame material, rubber formula, size, pattern on the basis of scientific calculation, (It is now possible to directly generate tire design drawings directly with the help of computer series and big data analysis). How the tires produced according to this design plan behave in the process of use [...]

What is the difference between natural crystal and quartz

What is the difference between natural crystal and quartz Natural crystals belong to the crystalline minerals of quartz. The main ingredient is silica. Due to various impurities in quartz, it is classified as different colors. However, natural crystals belong to quartz, but there are still some differences between them. Quartz is a mineral resource with very stable physical and chemical properties. The crystal belongs to the oxide mineral of the cubic system, namely low temperature quartz (a-quartz), which is the most [...]
