Industrial Air Knife Applications PCB Cleaning, Plating & Surface Drying
Spider Air Knife and Blower Air Knife Solutions for PCB Cleaning and Plating
In electronics manufacturing, plating, cleaning, and surface treatment processes, removing water, dust, particles, and residual liquids from the product surface can be an important part of production.
Different products and production lines require different airflow arrangements. A standard air nozzle may provide concentrated airflow at one point, while an industrial air knife can create a wider and more controlled air curtain across the working area.
This video combines three application scenes to show how SCB air knife systems can be used in different industrial environments. The first scene shows a spider air knife used for PCB cleaning. The second shows an air knife application in the plating industry. The third demonstrates a blower connected to three flexible hoses and air knives, showing how a complete airflow system can be configured for multiple working positions.
Spider Air Knife for PCB Cleaning
The first scene shows a spider air knife being used for PCB cleaning.
Printed circuit boards can go through different cleaning, washing, and processing stages during manufacturing. After cleaning, liquid, dust, and small particles may remain on the surface or around different areas of the board.
A spider-style air knife provides multiple directional airflow points, allowing air to reach different areas of the PCB.
Instead of using a single concentrated air stream, the airflow can be distributed around the working area. This makes the design suitable for applications where the product has a relatively wide surface or where airflow needs to reach several positions.
For PCB cleaning and drying, the actual airflow arrangement can be adjusted according to the board dimensions, conveyor speed, cleaning process, and required drying effect.
The objective is to provide controlled airflow without unnecessary air consumption.
Air Knife Applications in the Plating Industry
The second scene shows an air knife application in the plating industry.
Plated components may need to be rinsed or cleaned during the production process. After these stages, residual water or liquid can remain on the surface of the components.
An air knife can be positioned after the rinsing or cleaning section to help remove surface moisture before the product enters the next production stage.
For plating applications, the shape and size of the components can vary considerably. Some parts have flat surfaces, while others have holes, edges, grooves, or irregular shapes.
This means that the airflow direction and air knife position need to be considered according to the actual product.
A customized industrial air knife drying system can be designed to provide airflow from different directions when required.
Depending on the application, the air knife may be installed above, below, or beside the conveyor. Multiple air knives can also be used when one airflow direction cannot cover the complete working surface.
One Blower, Multiple Air Knife Connections
The third scene shows another practical configuration: one blower connected to three flexible hoses and air knives.
This type of setup can be useful when several working positions need airflow from the same blower.
The blower provides the air source, while flexible hoses deliver the airflow to individual air knives.
This configuration provides greater flexibility when designing an industrial airflow system. Instead of installing a separate blower for every air knife, one blower can potentially supply several air outlets when the required airflow and pressure are properly calculated.
However, the final configuration should always be based on the actual airflow requirements.
The hose diameter, hose length, fittings, air knife specifications, and blower capacity all affect the performance of the system.
Incorrect pipe sizing or excessive restrictions in the airflow path may reduce the airflow reaching the air knife.
For this reason, a blower and air knife system should be considered as a complete system rather than selecting the blower and air knife separately.
Why Customized Airflow Matters
Industrial products are rarely identical.
A PCB production line may require a different airflow arrangement from a plating line. A small component may require one air knife, while a wider product or larger amount of residual liquid may require multiple air knives.
This is why SCB focuses on customized airflow solutions.
When selecting an industrial air knife, several factors should be considered:
Product size and shape
Conveyor width
Conveyor speed
Amount of residual liquid
Required drying or cleaning effect
Working distance
Available installation space
Blower airflow and pressure
Pipe and hose dimensions
These factors determine how the air should be delivered to the product.
A correctly designed airflow system can help make the drying or cleaning process more consistent and easier to integrate into an existing production line.
Air Knives for Cleaning, Drying and Surface Treatment
Air knives are not limited to one specific application.
Depending on the airflow configuration, they can be used for:
PCB cleaning and drying
Remove residual liquid, dust, and particles from electronic components and circuit boards.
Plating applications
Remove surface moisture after rinsing or cleaning processes.
Metal parts drying
Remove water from components after washing and surface treatment.
Industrial surface drying
Dry products before inspection, packaging, coating, or further processing.
Conveyor drying
Create a continuous air curtain while products move through the production line.
Dust and particle removal
Use controlled airflow to remove loose contaminants from selected product surfaces.
The actual result depends on the product and process conditions, so the air knife should be selected according to the application rather than simply using a standard configuration.
Practical Blower & Air Knife Solutions from SCB
The three scenes in this video demonstrate three different aspects of industrial airflow technology.
The spider air knife provides directional airflow for PCB cleaning and drying.
The plating application demonstrates how air knives can be integrated into surface-treatment processes.
The blower with three flexible hoses demonstrates how one air source can be connected to multiple air knives when the system is properly configured.
SCB VACUUM provides industrial blowers, air knives, spider air knives, and customized airflow solutions for manufacturing applications.
For a new project or an existing production line, customers can provide product pictures, dimensions, conveyor speed, airflow requirements, and installation conditions. Based on these details, the air knife configuration and blower capacity can be evaluated according to the actual application.
For applications involving PCB cleaning, plating, metal drying, surface drying, or industrial cleaning, the right airflow arrangement can make the system more practical, flexible, and easier to integrate.
