The 12-inch Czochralski silicon was developed successfully in Ningbo Bonded Area for special large-scale integrated circuits. The project jointly undertaken by the State Key Laboratory of Silicon Materials of Zhejiang University, Heiner Semiconductor and Ningbo Lili Electronics Co., Ltd. was listed as a major project in the National High-Tech Research and Development Program (863 Program). 12-inch single-crystal silicon is used as the basic material for the most advanced ultra-large-scale integrated circuits in the world. Its successful development is of great significance for improving the quality and technological content of existing silicon wafers in China. This monocrystalline silicon ingot has a total length of about 60 centimeters, a diameter of 30 centimeters, and a weight of about 75 kilograms. The production process lasts for 40 hours, and the value of the raw material for light is 80,000 yuan.
twisted Paper Rope making machine
This is a good machine for making twisted paper ropes in roll, you can use the twisted ropes to wrap the gifts or for craft products, Paper Handle after knotted or tipped at the two ends or you can use it on the paper handle making to make different paper handles. It is running stably and fast and the rope diameters can be different and adjustable and customized according to customers` request. The rope can be made in different ways by using one paper roll, 2 rolls or more, which depends on the rope tightness, strongness, roundness and colors
