Once the atmospheric jet plasma cleaning machine fails, if it can not be eliminated in time, it will bring huge economic losses to enterprises. Atmospheric plasma cleaning machine and vacuum plasma cleaning machine, mechanical structure is relatively simple, in order to ensure production efficiency, the operator must have a certain ability to operate, the common troubleshooting methods are as follows: First, when the air jet plasma cleaning machine starts up, there is no plasma ejection can be divided into two situations: 1, the LCD panel does not display, the red LED indicator light is not bright: Countermeasures: Please check whether the power supply is normal and whether the power plug is in bad contact. 2, LCD display, red LED light flash (5 times per second); Countermeasures: A. Check whether the high-voltage wire falls off or is damaged, and replace it if it is damaged; B. If there is no problem with the high voltage wire, it may be the fault of the main board. Please contact the supplier to solve it as soon as possible. Two, the atmosphere jet type plasma cleaning machine after boot, instantly stop running for a period of time, red LED indicator light slowly flashing (1 times/second) : Action: Check the pressure of the pressure gauge is normal. If the pressure is too low or too high, adjust the pressure of the pressure gauge to this range. Check whether there is air leakage at the trachea connection and whether the trachea is damaged. If it is damaged, please replace the leaky joint with the damaged trachea. Three, atmospheric jet type plasma cleaning machine discharge inhomogeneity: 1. The sprinkler head should be replaced regularly: Atmospheric jet type plasma cleaning machine plasma is in the gas ionization by the nozzle spray, long time use will cause loss, will also make the nozzle internal carbonization phenomenon, and the serious loss of the nozzle will produce particles, affect the treatment effect of products, and then affect the quality of products. 2. Replace the inner electrode regularly: The inner electrode is consumable and should be checked frequently. If the loss depth is found to be around 2mm, it should be replaced. The discharge effect of atmospheric jet plasma cleaning machine will be seriously affected if the inner electrode is not replaced in time.
Wafer plasma cleaning machine source manufacturers
Wafer cleaning is divided into wet cleaning and dry cleaning, plasma cleaning belongs to the latter, mainly used to remove invisible surface contaminants on the wafer surface. In the process of cleaning, first put the chip in the vacuum reaction chamber of plasma cleaning machine, and then pumping air into vacuum state, after reaching a certain degree of vacuum, introducing the reaction gas, the reaction gas ionization plasma formation, and the chip surface, chemical and physical reactions between the volatile substances was siphoned off, make the chip surface clean water. A plasma cleaning machine for cleaning wafers: 1-1: Plasma cleaning of wafers is performed in cleanrooms of class 1000 and above, which requires extremely high particles. Any excessive particles can cause irreparable defects in the wafer. Therefore, the cavity of the plasma cleaning machine must first be aluminum, rather than stainless steel; The sliding part of the bracket where the wafer is placed should be made of materials that are not easy to produce dust and be corroded by plasma. Electrodes and brackets are easy to remove and maintain. 1-2: The electrode spacing, layer number and gas path distribution in the reaction chamber of plasma cleaner have great influence on the uniformity of wafer processing, and these indexes need to be optimized through continuous experiments. 1-3: In the process of plasma cleaning, there will be a certain amount of heat accumulation. It is necessary to keep the temperature of the electrode plate within a certain range, so the electrodes of the plasma cleaning machine are usually cooled by water. 1-4 The relatively high capacity of the multielectrode plasma cleaner allows multiple wafers to be placed on each bracket as needed, making it ideal for the removal of lithographic substrates for 4 "and 6" wafers used for discrete semiconductor devices and power electronic components. Two, plasma cleaning machine for wafer level packaging pretreatment: 2-1: WaferLevelPackage(WLP) is an advanced chip packaging method, that is, after the whole wafer production is completed, directly on the wafer packaging test, and then cut the whole wafer into a single core; The electrical connection uses copper bumps instead of lead bonding, so there is no lead bonding or glue filling process. 2-2: The purpose of wafer level packaging pretreatment is to remove the surface inorganic, reduce the oxide layer, increase the surface roughness of copper and improve the reliability of products. 2-3: Due to the needs of production capacity, there will be significant differences in the design of vacuum reaction chamber, electrode structure, airflow distribution, water cooling device, uniformity and other aspects. 2-4: After the chip is made, the residual photoresist cannot be wet-cleaned, but can only be removed by plasma. But the thickness of photoresist can not be determined, the corresponding process parameters need to be adjusted.
Plasma cleaning machine controller
Plasma cleaning machine equipment is a kind of new technology equipment used for surface treatment of electronic components and polymer materials. It is generally believed that plasma equipment has automatic control system, and the reliability and reliability of the automatic control system of the new technology machine equipment is more strict than the general equipment, the control system is as important to the equipment as the human brain. So what requirements does the device need to be met by the controller? In order to ensure that each sub-system can work normally, the plasma cleaning machine has an automatic control system (controller), which can issue work instructions to each sub-system. Systems are like our brains, and when instructed, they assign tasks to each structure to complete. There are many kinds of control panels sold on the market, the quality and price are very different, the reliability and service life of the control panel are also different. Many customers in the purchase of equipment, will stipulate the cleaning machine parts should be used which manufacturer's model specifications, some parts use domestic suppliers, some key parts are imported, manufacturers in the manufacturing process will be according to customer requirements for assembly configuration. In the production and processing of equipment, customers with higher requirements require plasma cleaning machine manufacturers equipped with imported controllers, imported controllers are expensive, but because of its reliability and service cycle and other reasons, often get the approval of manufacturers. Of course, some of the technical strength of the domestic controller manufacturers even reach the standards of imports. The control board is the key to monitor and manipulate the modulus of the control board of the vacuum plasma cleaning machine. The processing process is very complex, and the actual operation of logic and data information is carried out. Therefore, the vacuum machine can choose the high-precision control board. The key of the control board of atmospheric plasma cleaning equipment is used for precise positioning, simulation, logic operation and the setting and management of the main parameters. The PLC is used for accurate positioning and analog acquisition, and the main parameters of the system are monitored in real time according to the touch screen of the Ethernet port. Plasma cleaning machine is divided into vacuum and non-vacuum two types, non-vacuum is atmospheric pressure, or atmospheric pressure plasma cleaning machine, non-vacuum plasma cleaning machine, mainly used to clean flat objects, like mobile phone glass cover plate, or some small range of cleaning.
