Almost all existing and upcoming circuit board factories use new environmentally friendly cleaning techniques. You also need a new drying method. After aqueous washing, flux and other contaminants are removed. Furthermore, another type of purge-based cleaning part has begun the tendency of water-soluble cleaning in other industries. In addition, due to changes in aqueous inks, paints, coatings, adhesives and other solutions used in various manufacturing processes, there has been a need for air knife dryers that have never been seen before. Before the Montreal Protocol and the global industry met environmental regulatory requirements, the Air Knife business became an industry.
The length of the air knife in the production line is usually 0.25 to 200 inches and the discharge groove or opening range is 0.001 to 0.25 inches. According to applicable standards, a static wind knife configuration may require 1-10 air knifes. Air gives the desired amount of desired and air velocity of the exhaust fan through the air knife slot through the air generator slot (industrial blower or air compressor).
When choosing a compressor and blower, many applications have to consider environmental issues, efficiency, and duty cycle. Compressed air is the most inefficient when used in conjunction with air knifes for ventilation into the air, and can primarily use air. The pipe provided with an air knife is suitable for limited space as it can be reduced to 6.4 mm (1/4 inch) in diameter. The fan-operated air knifes should provide larger sizes and ducts of larger diameter air ducts, but increasing efficiency compared to compressed air is easily solved by saving on electricity costs.
