Description

TECHNICAL FIELD

[0002] In the field of electronic manufacturing, chemical nickel-plated products are widely used due to their good electrical conductivity and low cost. The deposition process of chemical nickel-plated products is not affected by the geometry of the workpiece, and the use of substrates is widely applicable, making product manufacturing more convenient. Chemical nickel-plated products have high corrosion resistance and high wear resistance, making the product have a longer service life in use. Chemical nickel-plated products also have good electrical conductivity and weldability, making the product more advantageous than other workpieces in subsequent secondary processing.

[0003] However, in the high-temperature and high-humidity environment of summer, these products are prone to oxidation when exposed to air, resulting in surface contamination, which in turn affects the weldability and wire bonding performance of the product. The existing cleaning device needs a long time to complete the cleaning of a product, which not only increases the time of the product exposed to the air, reduces the yield of the product, but also further affects the quality of the product due to the water quality used in the cleaning process. The existing sink often needs energy or human intervention to change water, which consumes more resources and increases production costs. The commonly used filter device will reduce the filtering quality due to the continuous use of the filter screen or filter element. More seriously, the pipeline may be blocked due to the accumulation of impurities on the filter screen, resulting in backflow or overflow of sewage and causing serious production accidents. During the use of the soaking tank, impurities will continuously adhere to the tank wall, which will continuously affect the water quality and in turn affect the product quality. Therefore, some equipment is needed to solve these problems. SUMMARY
