1, will the car chip still be short? According to the CEO of Stellantis, the semiconductor crisis may continue until 2022. The demand for chips in the automotive industry is increasing, especially under the development trend of autonomous driving and intelligence, the shortage of automotive chips is difficult to solve.
2, the car chip will be short. Semiconductor supplier company executives have revealed that the broader chip shortage could last until mid-2022, which may be an optimistic estimate. Some suppliers are evenWays are being sought to recycle old chips to help further ease the shortage. 3, according to NXP Semiconductor's forecast, the supply of automotive chips will be very tight throughout 2021, and remind the automotive industry that the chip shortage problem may continue into 2022. The chip shortage has led to an expansion of the wave of shutdowns in Europe, the United States and Japan, with major automakers including BMW, Daimler and Honda announcing the latest stoppage plans.
1, recycling pcb board price from70 yuan to 350 yuan, mainly used for one-time production, a large number of complex functional development and equipment parts manufacturing. At present, many designers use atomic communication tools to design novel communication products through a series of advanced processing work.
2, recycling circuit board 3-20 yuan or so a catty. Used circuit boards, the current basic market recycling price is about 8 yuan per catty, a ton is equal to 2000 catty, 8 times 2000 is a ton of money about 7600 yuan.
3, recycling 1 ton of waste circuit boards is about 6000 yuan, according to the differences in each region, the price will beThe material is usually copper-iron ore, and there are usually three kinds: pyrite, oxy-iron, and natural copper.
Through melting smelting and electrolytic fine fire smelting to produce cathode copper, that is, electrolytic copper, generally suitable for high-grade copper sulfide.
Copper refining process mainly uses copper sulfide concentrate as raw material, including roasting, melting, blowing and refining and other processes. Roasting is divided into semi-oxidation roasting and total oxidation roasting, the purpose is to remove sulfur and some impurities in the concentrate.
Copper is smelted from ore with the catalysis of other additives. The fourth part is purification. When silver was extracted from copper, copper became more pureHigh, the specific approach is: people add lead to the copper liquid, the lead raises the silver in the copper, the lead sinks to the bottom, and the silver copper liquid is removed in the upper part to achieve the purpose of obtaining high purity copper.
