Q:The production of silicon units do front-line production workers harmful to the body
There are still some damage, some of the silicon wafer plant dust, strong acid, alkali, more depends on the configuration of the factory environment and labor insurance supplies
Q:What are the difficulties of silicon wafer cutting?
During the cutting process, the wafer quality and rate of finished products played a major role in the grain type, viscosity of silicon carbide powder cutting fluid and particle size, the viscosity of mortar, mortar flow, steel wire speed and wire tension and workpiece feed speed.TTV: and TTV stria stria and is a headache in the wafer processing, from time to time there will be a knife, impossible to guard against. TTV is when the knife into the line, and is easy to appear in the time line bow.
Q:One hundred watts of solar panels to how many pieces of silicon wafers, 156 of single crystals and polycrystalline
As for the power, according to the W=UI formula can be obtained, since a single voltage is fixed, the resulting current size determines the power of a battery, the current per tablet produced is not fixed, with the conversion rate of the conversion rate, high current is large, the reverse is small; the same the power conversion rate is high, the area is small
Q:What is a good solar wafer testing equipment?
To develop solar energy, we must overcome two key challenges: cost and yield." In the solar panel manufacturing process, from the front to the back, from the crystal rod, wafer, chip to the module, any one of the links in error, will affect the number of solar panel products. Therefore, the solar cell needs to be able to monitor every step of the process in the production process of detection tools. QCROBOT also has many successful cases in this field.
Q:How to make monocrystalline silicon solar cells
Phosphate glassThe process is used for solar cell production in the manufacturing process, through chemical etching silicon that is immersed in hydrofluoric acid solution, complexes six fluorosilicic acid to produce chemical reaction to produce soluble phosphorus silicon glass layer, a diffusion system to remove the node after the formation of the surface of the silicon wafer. In the diffusion process, POCL3 reacts with O2 to form P2O5 on the surface of silicon wafer. P2O5 reacted with Si to produce SiO2 and phosphorus atoms, which form a layer of phosphorus containing SiO2 on the surface of the silicon wafer. Removing phosphorosilicate glass equipment is generally composed of a main body, a cleaning tank, manipulator, servo drive system, electric control system and the automatic mixing acid system components, the main power source of hydrofluoric acid, nitrogen, compressed air, water, wastewater and exhaust heat. Hydrofluoric acid is capable of dissolving silicon dioxide because of the reaction of hydrofluoric acid and silica to produce volatile four fluorinated silicon gas. If the hydrofluoric acid is too heavy, the reaction of four fluorinated silicon will further react with hydrofluoric acid to produce soluble complex and the material of the six fluorine acid.
Q:Monocrystalline silicon processing technology
The use of more than one set of cutting lines is an innovative way to increase the output of the machine under the condition of keeping the speed. The latest MaxEdge system of applied materials company uses a unique set of two independent control cutting components.MaxEdge is the industry's first use of specially designed fine wire secant system, the minimum can reach 80 M. Compared with the HCT B5 wire system applied materials industry leading, these improvements reduce the loss of the silicon material yield up to 50%.Wire system with higher productivity can reduce the number of tools in wafer yield under the same. Therefore, manufacturers can significantly reduce the cost of equipment, operators and maintenance.Reducing the consumption of silicon wafers is directly reducing the cost per watt of solar power.Wire products marketThe silicon wafer suppliers and hope to integrate the crystalline silicon PV module manufacturers to control their own slice process requires the use of wire saw device. Monocrystalline silicon and polycrystalline silicon photovoltaic technology are needed to use it.
Q:How to extract silicon from silicon wafers
Chamfer: the annealed silicon wafer is trimmed into an arc shape, which can prevent the wafer edge from cracking and lattice defect, and increase the flatness of the epitaxial layer and the photoresist layer. In this process, the silica fume is produced by water leaching to produce waste water and silicon slag. [1]
Q:There is a micro structure on the side of the silicon wafer
It is a milestone in the progress of science and technology that 160 thousand transistors have been integrated on a large grain of silicon.
Q:The benefits of silicon chip
(1) classification of silicon steel sheetA and silicon steel sheet can be divided into two kinds: low silicon and high silicon. Low silicon silicon containing less than 2.8%, it has a certain mechanical strength, mainly used in the manufacture of motor, commonly known as dynamosheet; high silicon silicon content is 2.8%-4.8%, it has good magnetic properties, but more brittle, mainly used in the manufacture of transformer core, commonly known as the transformer silicon steel sheet. There is no strict limit in the actual use, the use of large silicon wafer manufacturing large motor. B, according to production and processing process can be divided into two kinds of hot rolling and cold rolling, cold rolling can be divided into grain orientation and grain orientation of the two. Cold rolled sheet of uniform thickness, good surface quality, high magnetic, therefore, with the development of industry, the trend of hot rolled sheet is cold rolled sheet has replaced (China has explicitly requested to stop the use of hot rolled silicon steel sheet, which is called "pre cold generation of heat")
Q:How do we use the scanning electron microscope
Most of the samples prepared by silicon wafer were dispersed on the surface of silicon wafer after the dispersion of nano particles. The test results and this kind of sample is silicon pretreatment, the main drying and sample dispersion and sample, the majority of small particle size, easy to agglomerate, take the solution can take the middle or upper clear liquid
