The fine step of the lead bonding package begins with the cutting. After the precision wafer is thinned, the automated tool accurately slices it to ensure smooth and silky edges. The chip is then carefully bonded to the matching size pad, with the use of soft solder or polymer to enhance the stability of the connection. Gold wire bonding technology is the key link, and hot pressure welding and thermoultrasonic welding technology are used, which requires high linear accuracy and just right bonding arc.
Core process wire bonding: The traditional use of 0.025-0.032mm diameter of gold wire,The bonding process includes thermo-compression welding and thermo-ultrasonic welding. The gold wire is bonded at 100-400 ° C, and the study tries to replace it with aluminum or copper to reduce the temperature and improve the life of the device. Plasma cleaning ensures film adhesion in key steps, such as enhancing Au film adhesion on Si substrates.
Architecturally speaking, SiP integrates a variety of functional chips, including processors, memory and other functional chips in a package, so as to achieve a basically complete function. Corresponds to SOC (System on Chip). The difference is that system-level packaging is a side-by-side or superimposed package of different chips, andSocs are highly integrated chip products.
Air-cooled car: a vehicle that uses air to cool its engine. APC: May refer to punched cards, an input device for early computers. ASU: Interference suppression system for reducing interference in wireless communications. baby car: Minicar, a small, lightweight car model. backfiring: carburetor backfiring, abnormal engine combustion. baggage car: Luggage cart, a vehicle used for transporting goods.
Auto parts staff work inspirational quotes do not eat, do not sleep, play up to earn money! No education can match adversity. Success is not easy, we must redouble our efforts! Sunshine always after the rain, after the rain to see the rainbow! Only a quick axe, no wood can not be split. The most terrible enemy is not a strong belief. People are distinguished according to quality, and pay is based on performance.
Auto parts are a product that constitutes each unit of the car as a whole and serves the car. All parts, assemblies and assemblies applicable to automobiles (including them)The basic parts) and the assembly are collectively referred to as auto parts. In addition to the name, the concept includes varieties and specifications. Some are suitable for general parts of the car, and some can also be treated as auto parts, such as bearings, general electric equipment, etc.
The idioms of spare parts are: scattered stars, matching the dragon, sharing from the rainbow. Spare parts idioms are: scattered, scattered stars, sharing from the life. 2: Pinyin is, lingpeijian. 3: The structure is zero (upper and lower structure) with (left and right structure) pieces (left and right structure).
Therefore, the factory parts have the LOGO of the car brand.Auxiliary factory: refers to the spare parts produced by the manufacturer authorized by the non-automobile manufacturer, which is marked with its own factory name and has its own trademark, but does not have the LOGO of the automobile brand (otherwise it is illegal). Original factory: is the original supporting products, specifications and materials are tested, the performance has also been tested. Matching: Matching is something that can be fitted into the car, is something that can be used together.
1, that is to say wireless charging hot press , the tankUnder normal pressure wireless charging hot pressing , Beilun District liquid automatic filling machine manufacturers supply wireless charging hot pressing , only the packaging container is vacuum, Beilun District liquid automatic filling machine manufacturers supply. The liquid material depends on the pressure difference between the tank and container to be filled in order to complete the filling. This method is commonly used in China. Which liquid filling machine is better Wireless charging hot pressing ? In the packaging industry, the demand for liquid automatic filling machines is very high.
2, under the premise of continuous operation of the filling and sealing machine, you can still see the application advantages of the filling and sealing machine, Zhejiang filling and sealing machine factory supply, Zhejiang filling and sealing machine factory supply, enterprises to understand the changes in the situation, under the premise of continuous operation of the filling and sealing machine, You can still see the advantages of filling and sealing machine, and the application of this type of equipment provides a basic guarantee for the development of various industries.
