Ultrasonic Atomizer Spraying Film Preparation Method

This paper introduces a kind of ultrasonic atomizer spraying film preparation method, its main use precision ultrasonic atomization device to spray liquid atomization into super fine droplets, with the help of plus auxiliary air flow should be more evenly attached to the base material surface, to form a uniform thickness control, high quality of the coating appearance, so as to solve the existing spraying technology of surface coating uniformity is bad, the coating effect is poor, spraying is controllable and the productivity is low, to achieve the purpose of precise spraying. Compared with the existing technology, ultrasonic atomizer spraying film preparation method of coating with high efficiency, the quality of coating film is high, good repeatability, high solution efficiency and spraying area and the coating thickness can be precise control, etc.

Flux spraying pressure spraying first flux to the PCB, this way of spraying, under the action of air pressure, enhanced additionally is larger, the workshop the flavor of permeate flux, long-term inhalation can cause dizziness and nausea, if the flux is toxic, will cause irreparable consequences to human body. At the same time, high pressure spraying equipment and more difficult to maintain and trouble, residues of flux is not easy to be cleared within the equipment clean, and spraying pipe jams easily, unsafe, colleagues PCB board face remain serious, need to arrange personnel to clean. Solder joint quality stability, spraying quality consistency control is very difficult, even the employees with many years of spraying welding experience cannot be guaranteed. Considering from the personnel safety and quality of spraying, CHEERSONIC r&d ultrasonic atomizer spraying film preparation equipment, without high pressure effect flux low velocity can be gently spraying to PCB, and through the liquid velocity and quantity of the system control spraying.

Ultrasonic atomizer spraying film preparation device different from traditional high pressure sprayer, spray forming principle is different, is the use of ultrasonic vibration, the liquid interface under the effect of ultrasonic, the separated form the atomized droplets, the atomized droplets grain diameter is determined by ultrasonic frequency, the higher frequency of small particle diameter, and the low velocity of the surface of the liquid atomization effect is better, so ultrasonic spray can realize low speed soft atomization effect, cooperate CHEERSONIC independent research and development of gas system and 6 axis control system to control the direction and the way of spraying.
