Q:How many watts can a piece of silicon produce
The content of silicon in the earth's crust is 25.8%, which provides an inexhaustible source for the production of monocrystalline silicon. Because silicon is one of the most abundant elements in the earth, the solar battery that destined to enter the mass market (mass market) products, reserves of advantage is to become one of the reasons the main photovoltaic silicon materials.
Q:The benefits of silicon chip
The silicon steel sheet (sheet) Grade 600 to 1300Use: tableware / Accessories / motor can container / air conditioning accessories / small appliance parts / Accessories / microwave / lighting hardware accessories / furniture fittingsHardware knowledge: xigangpianElectrical silicon steel sheet or silicon steel sheet or steel sheet. As the name suggests, it is a silicon containing up to 0.8%-4.8% of electrical silicon steel, made of hot, cold rolled. General thickness below 1mm, so called sheet. The silicon steel sheet is a kind of plate, which is independent of its special use.The silicon steel sheet used in electrical engineering has excellent electromagnetic properties and is an important magnetic material in electric power, telecommunication and instrument industry.
Q:Who is the best silicon chip dryer?
Heating oil bath furnace and electric heating two ways, our company is now used in the two, it should be said that each has its advantages and disadvantages
Q:How to deal with silicon wafer annealing
Another fact: if the same "complement", can be understood as: oxygen from the surface after the removal of impurities, near the surface of the reduced defects is also reduced, the mean free path of carrier mobility increases, also increases, which leads to the decrease of resistivity.
Q:How much a piece of silicon on the board
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, whereas small;
Q:Seeking for the video: manual insert silicon wafer single crystal insert method
To solve the finger print is very simple, as long as the requirements of employees can not in the whole process of operation of the silicon bare hand contact can be, no debris is not possible, but to see the machine or man-made debris or before the procedure is cracked as, if it is man-made debris, to do a a standard specification, as long as the control that would reduce the rate of fragmentation. Or artificial debris to staff assessment, but also meet the results. I used to track debris for a long time, when all of the pieces are controlled by the descendants of the debris is very low. The main road is the most hidden crack. If the semi automatic equipment under normal circumstances will not produce debris, such as automatic equipment, such as degumming equipment will produce debris, mainly the spray pressure is too large, but the pressure is also very little fragmentation of the right. I think the main thing is to see if you have asked the staff how to do it, followed by the implementation of your employees are required. You can look at these lines on the line!
Q:Monocrystalline silicon processing technology
Cut diameterFine cutting lines mean lower kerf loss, that is to say with a piece of silicon can produce more silicon. However, the cutting line is thinner and more prone to fracture.loadThe total area of each cut is equal to the area of the wafer X the number of silicon blocks per cut X the number of chips per silicon block.Cutting speedThe cutting table cuts the speed of the web through the cutting line, which is largely determined by the cutting line moving speed, the motor power and the cutting wire tension.Easy maintenanceNeed to replace the wire cutting line and grinding slurry in cutting, maintain faster, higher overall productivity.Producers must balance these factors to maximize productivity. Higher cutting speed and greater load will increase the tension of the cutting line and increase the risk of breakage. Since all the chips on the same silicon chip are cut at the same time, as long as there is a cutting line broken, all the chips have to be discarded. However, it is not advisable to use a thicker and stronger cutting line, which reduces the number of wafers produced per cut and increases the consumption of silicon materials.
Q:What's the difference between a silicon wafer and a battery?
Silicon wafers are cut into pieces by wire cutting!The battery pack is a silicon wafer through the surface flocking, diffusion of PN junction, and then PECVD coating
Q:What are the aspects of silicon wafer testing?
Test wafer sizeThe damage degree of monocrystalline silicon wafer was measured and classified:Damage less than 30mm, can be cut into 6 inches Wafer;Broken into two pieces, can not be used;No damage;Wafer size 156*156mm;Detection speed requirements: 1.5 seconds / piece;Action process: the movement of the wafer to the detection position, the camera quickly take pictures, and then processed in the process of equipment;Wafer movement speed: about 150mm/s;
Q:What is the specific way to clean the silicon wafer suede concrete steps
. Because of the advantages of easy control, low voltage DC drive, rich color after combination, long service life and so on, it is widely used in various engineering, large screen display system. LED can be used as a display, under the control of the computer, display color changes in the video and pictures. LED is a semiconductor capable of converting electrical energy into visible light
