XJY-8206 VMQ Silicone resin
Methyl Vinyl MQ Silicone Resin(VMQ resin, Vinyl MQ resin, VQM resin)
XJY's hydrogen-containing series is used as a crosslinking agent, and XJY-8206 series is used as a hardening agent. The silicone rubber used in this product is widely used in the field of electronic packaging, which has good insulation and protection properties.
Electronic components are sometimes encased in silicone to increase stability against mechanical and electrical shock, radiation and vibration, a process called “potting”. Silicones are used where durability and high performance are demanded of components under hard conditions, such as in space (satellite technology). Silicones also have the advantage of little exothermic heat rise during cure, low toxicity, good electrical properties and high purity.
The wide acceptance of silicones in the electronics industry is due to several technical and mechanical properties including:
High-performance electrical materials made with silicone technology are making their way into today's increasingly demanding electronic and electrical applications. Room Temperature Vulcanizing is widely used in this field as permanently flexible rubber. Silicones can seal and protect sensitive electronic components, semiconductors, and devices from heat, contamination and accidental damage, and help ensure a continuous supply of electricity.
Electronic grade silicone adhesives sealants are the common material insulating corrosion-sensitive electronic components.
|Silicone electronic sealant is a kind of composite material that is liquid before curing, has certain fluidity, and is cured under a certain time, heating, or other conditions to form an elastomer. Its main function is used for bonding, sealing, potting and coating protection of electronic components, and plays the role of waterproof, moisture-proof, dust-proof, anti-corrosion, and shock-proof. In order to protect electronic products from the erosion of the natural environment and prolong their service life, more stringent requirements are placed on the weather resistance, heat dissipation, shock resistance, and water resistance of electronic appliances.|
Silicone sealant has stable physical and chemical properties, good high and low-temperature resistance, fast working when cure mechanism begins to contact the air, and can work for a long time in the range of -50~200 °C with stable performance. It has excellent electrical performance and insulating ability because of its high surface resistivity, good dielectric properties, and resists electrical tracking. After potting, it can effectively improve the insulation between internal components and lines, and improve the stability of electronic components. Silicone electronic sealant is soft after proper cure, and higher humidity accelerates cure, which can eliminate most mechanical stress and provide shock absorption protection.
Therefore, silicone sealants are ideally suited for the electrical properties required by electronic appliances, have been used more and more in the industry, and have been recognized by more and more customers.
During the printed circuit boards process of silicone electronic sealant, the polymer bodies are closely connected together to form a good adhesive force and will not be easily pulled apart by external forces. As if it has an attraction, it will not volatilize and not break. In order to ensure the bonding effect, do not apply too thick, just evenly. If the adhesive layer is too thick, it will affect the adhesion and cannot exert good adhesion. Don't be too greedy when smearing, just complete the seal.
Electronic grade silicone potting material has stable dielectric insulation, which is an effective guarantee to prevent environmental pollution and insulating corrosion sensitive electronic. At the same time, it can eliminate the stress caused by impact and vibration in a large temperature and humidity range. Based on the condensation system and addition curing system, there is no need for secondary curing, which can meet the special requirements of bonding, heat conduction, flame retardant and high transparency. After curing, it becomes a flexible elastomer; The curing speed is uniform, which has nothing to do with the thickness of potting and the sealing degree of the environment.
Heat conductive potting adhesive is a two-component silicone heat conductive potting adhesive, which can reliably maintain sensitive circuits and components for a long time in a wide range of temperature and humidity changes. It has excellent electrical insulation function in insulating corrosion sensitive electronic, can withstand environmental pollution and avoid harm to products caused by environmental factors such as stress, sensation and humidity. It is especially suitable for products requiring good heat dissipation of potting materials. Heat conductive potting adhesive has excellent physical and chemical resistance. After 1:1 mixing, it can be cured at room temperature or heated quickly, with minimal shortening, no heat release during the curing process, no solvent or curing by-products, repairable, and can be deeply cured into the elastomer.
Semiconductors chip manufacturing involves five production stages: wafer preparation, wafer fabrication, wafer testing/selection, assembly and packaging and testing, and final testing, which are independent of each other, while silicone specialty gases are more or less involved in each link.
For example, in order to provide the required energy to the reaction system, it is necessary to deposit a solid film on the surface of the silicon wafer by mixing gases, a process called "chemical vapor deposition (CVD)". The chemical vapor deposition process is divided into three important stages: the diffusion of the reactive gas to the surface of the substrate, the adsorption of the reactive gas on the surface of the substrate, the chemical reaction on the surface of the substrate to form solid deposits, and the produced gas phase by-products are removed from the surface of the substrate.
Among them are organosilicon silanes. Organosilicon silane is one of the main media used in the etching process. At present, there are more than 110 special gases used in the semiconductor industry, of which 20-30 are commonly used. Among them, XJY-706 1,1,3,3-Tetramethyldisiloxane and XJY-705 1,3,5,7-Tetramethylcyclotetrasiloxane can be used in chemical vapor deposition for depositing silicon film.
