Ultrasonic Spray Coating for PCB

Ultrasonic spraying technology has demonstrated its significant advantages in PCB coating preparation, such as precise control of spray flow, improved coating uniformity and efficiency, etc. This technology provides a new and efficient way to protect and enhance functions of PCBs. The following are the specific applications of ultrasonic spraying equipment for PCB spraying:

1. Nanotechnology
– Nanotechnology is increasingly used in several areas, including as protective coatings. During the PCB production process, the use of nano-coatings can cover and seal important working parts, providing reliable protection against damage. Compared with traditional conformal coatings, nanocoatings have lower porosity, higher bonding strength and hardness, and excellent oxidation resistance and corrosion resistance.
– The ultrasonic nozzle technology used in ultrasonic spray equipment can provide a uniform and efficient film. This technology not only accurately controls the atomization flow rate, but also enables continuous spraying at low flow rates, making the spray shape easy to control and shape. This method not only increases the mechanical arm of spraying, but also can prepare stable and efficient PCB board coating.

2. Spraying efficiency
-Using ultrasonic spray technology, the conversion rate of solution can be greatly improved (≥95%), thereby saving solution usage and reducing costs. This high-efficiency spraying technology ensures full utilization of raw materials, while also reducing raw material waste and air pollution caused by back-spraying.
– The use of ultrasonic nozzles revolutionizes traditional coating methods, delivering unparalleled efficiency and consistency. Since the mid-1980s, semiconductor manufacturers have applied this technology to silicon and gallium arsenide wafer substrates, achieving unprecedented high-precision photolithography. This shows that ultrasonic spray technology has excellent performance in fine processing.

3. Spraying accuracy
– Ultrasonic spray equipment can precisely control the sprayed flux and other liquid materials, which is especially important for PCB manufacturing. Ultrasonic spraying of PCB boards can achieve a highly uniform flux film applied to the target area with almost no overspray and clogging. This uniform and fine spraying effect is achieved through the high-frequency vibration of the ultrasonic nozzle. This technology does not rely on external airflow to form an atomization effect, so it can better control the spraying flow rate, speed and direction.
– Ultrasonic spray technology provides a precise, repeatable and controllable spray solution. This kind of precision is particularly needed in PCB manufacturing because it allows for an extremely uniform flux film to be sprayed on the substrate, which is critical to ensuring circuit stability and long-term operational reliability.

4. Widely used
– Ultrasonic spraying technology is not only suitable for PCB production, but also widely used in new energy, medical, microelectronics, semiconductor and other fields. For example, in the field of new energy, it is used in the manufacture of fuel cells and solar cells; in the medical field, it is used in the manufacture of balloon catheters and syringes; in the field of microelectronics and semiconductors, it involves the production of flux and photoresist. Coating and other processes. These application examples illustrate the broad applicability and revolutionary significance of ultrasonic spray technology.

In general, ultrasonic spray equipment plays an important role in the production and processing of PCBs. Through this technology, the quality and uniformity of PCB coating can be effectively improved while reducing material waste and environmental pollution. The high precision and efficiency of ultrasonic spraying equipment make it one of the indispensable tools in modern electronic product manufacturing.
