High dependence on electronic parts industry for the dispensing process, most packaging or other work needs to be applied to potting dispensing equipment to improve the quality of the products, the surface of the chip package can be accomplished by high precision jet dispensing machine, glue coating by high precision spray valve can complete all kinds of irregular path, through the glue spray after spraying in order to achieve a comprehensive package, the package can be a long time to ensure high quality of work, and have waterproof and dustproof ability, can withstand the shock does not affect the normal work effect, effectively improve the performance and value of chip. High precision jet dispensing machine has applied in various production work, some small crafts need to carry out a full range of adhesive glue, this time need to be applied to the high precision spraying process, spray glue coating can ensure the work area, the bonding effect crafts more comprehensive and more practical, greatly improved the quality and value of Arts and crafts. Provide important help spray process for the development of China's manufacturing industry, manufacturing production requires high precision glue coating, by using high precision pointglue injection can effectively meet the job requirements of the majority of manufacturers.
