Why Vapor Degreasing Solvent Is The Future of PCB Manufacturing
As technology advances, Printed Circuit Boards (PCBs) are critical components in a wide range of electronic devices, from smartphones and laptops to medical equipment and industrial controls. To ensure optimal performance and longer lifespan, cleaning is a necessary step in the PCB manufacturing process, as it eliminates any harmful contaminants and generate the following advantage to PCB;
• Improve Aesthetic Appearance of PCB
• Improve Reliability of PCB
• Prevent Corrosion on Components and PCB
• Avoid Adhesion Problems with adhesive and Conformal Coating
• Prevent Dendritic Growth from Ionic Contamination
In this article, we'll explore why using a PCB vapor degreasing solvent is essential for efficient manufacturing.
Vapor Degreasing Solvent and Its Benefits
Cleaning electronic assemblies and circuit boards can be a challenging task. With PCBs becoming more complex and smaller in size, it has become even more difficult to clean them properly.
One of the most effective and efficient types is vapor degreasing solvent. This process involves rinsing and cleaning parts in ultra-pure vapor. The vapor then condenses on the surface of the parts dissolving the contaminants. As the solvent drips off the objects, it removes the soil/stain with it. This is a closed-loop process, so the solvent is cycled over-and-over again.
The cleaning method doesn't involve water or scrubbing and can effectively eliminate all oils, films and debris created during electronic circuit production without any harm.
Vapor degreasing solvent offers several benefits over other types of cleaning solutions:
• Superior cleaning results
• Repeatability
• Independent on operator techniques and manual cleaning methods
• Enables objects to dry quickly without a secondary drying process
Choosing the Right Cleaning Solvent for Your Manufacturing Process
Choosing the right cleaning solvent for your manufacturing process can be a challenge to ensure that you select the appropriate solvent that effectively cleans your specific contaminants without causing harm to your components if they are sensitive to solvent exposure. There are several factors to consider:
• Type of contaminants you need to remove
• Materials and components on the PCB
• Safety and environmental concerns
Today, vapor degreasing solvents need to be powerful enough for effective precision cleaning while also being safe and environmentally friendly.
