钻石线切割的行业新闻和市场见解, 精密加工与先进材料.
随着清洁能源的快速发展, 光伏发电的平价上网目标也迫在眉睫. 而光伏行业的各种晶体硅制造商都在不断扩大他们的生产能力, 他们还在不断降低生产成本, 由于小硅锭的切割是晶体硅太阳能电池成本的重要组成部分. Key Takeaways Crystalline silicon ingots can be cut with inner-diameter blades, slurry wire saws or fixed diamond wire loops; diamond wire is...
Key Takeaways Sapphire wafers are about 0.2 mm thick — close to the diamond wire diameter — so roughly 40-50% of every ingot becomes cutting-waste powder washed away by coolant, and most of it has historically been landfilled. Analysis of washed, dried and sieved diamond-wire cutting waste shows alpha-alumina as the main component, with nickel (0.70%) and diamond (0.164%) as the main impurities. Ultrasound acid leaching beats conventional acid leaching for nickel removal: nickel falls to 0.009% at a 99.67% leaching ratio, 和...
抽象: 本研究调查了不同树脂粘合剂对金刚石线环切割性能的影响. Resin-cured hardness samples were prepared using pure phenolic resin, epoxy-modified phenolic resin, and aromatic alkyl-modified phenolic resin, and their Rockwell hardness was tested. The fractured surfaces of the cured resin samples were observed using scanning electron microscopy, revealing varying levels of density post-curing. Diamond wire loops were then manufactured for single crystal silicon cutting experiments. The experimental results demonstrate that diamond wire loops made...
KDP 晶体简介 KDP 晶体具有较大的非线性光学系数和较高的激光损伤阈值, making them important component materials in optical systems for high-energy engineering. KDP crystals belong to hard-to-process brittle materials, distinguishing them from traditional metal materials processing. Manufacturing Process of KDP Crystals The manufacturing process involves cutting into a rough shape and then a precision cut. Cutting is the first step in processing KDP crystal materials. Due to localized stress in the crystal blank, the entire crystal...
考虑切削液对金刚石丝圈切割质量的影响时, 有几个因素在起作用. 切削液的选择会显著影响切削过程的效率和有效性. 以下是需要考虑的一些方面: 切削液的概念： 切削液, 也称为切削油或冷却液, 有油基和水基两种形式, 服务于多种用途，例如清洁, 润滑, 以及加工过程中的冷却. These fluids are crucial in maintaining...
Key Takeaways A single-crystal silicon ingot goes through cropping, diameter grinding, 切片, edge chamfering, lapping and polishing before it is ready for lithography. Surface accuracy at the slicing stage determines how much downstream planarization work is required. Diamond wire slicing is the standard way to turn an ingot into bare wafers with tight thickness variation and low sub-surface damage. 在单晶硅晶圆制备阶段, the silicon single-crystal ingots need to be processed into raw silicon wafers or barewa-fers with high surface accuracy...
What is a Semiconductor A semiconductor chip, 通常称为集成电路, is a semiconductor device fabricated on a semiconductor wafer through processes such as etching, wiring, and patterning to achieve specific functions. Beyond silicon chips, common semiconductor materials include gallium arsenide, 氮化镓, 和碳化硅. Key Takeaways Semiconductors are materials with conductivity between conductors and insulators, forming the basis of all integrated circuits. Beyond silicon, key semiconductor types include gallium arsenide (砷化镓), 氮化镓 (赣语) 和碳化硅 (原文如此), each...
Key Takeaways A semiconductor is a material with properties between an insulator and a conductor, 可以通过掺杂和电场进行控制.
