Additional Information
Reflow is a process in electronics manufacturing where solder paste is heated to melt and form reliable electrical connections between components and the printed circuit board (PCB). After heating, the solder cools and solidifies, securing the components in place.
During reflow, flux from the solder paste leaves behind residues on the PCB. These residues can affect electrical performance, cause corrosion, or impact reliability over time. Cleaning removes these contaminants, ensuring optimal functionality, long-term reliability, and a clean final product.
Types of Cleaning

Why is PCB Cleaning Required?
After reflow soldering, the PCB (printed circuit board) is cleaned to remove any leftover flux and solder paste residues.
Even though the solder is solidified and the components are attached, flux residues can be sticky or corrosive, and over time they can:
- Causes electrical leakage or short circuits
- Promote corrosion on metal surfaces
- Affect the board’s reliability and appearance
Using a cleaner like CIPEX 40 or 50, the PCB is washed to remove all residues and leave the board clean and ready for use or further assembly.
Uses pressurized jets of cleaning fluid to remove residues from surfaces and components. Effective for fast, uniform cleaning of larger areas and external parts.
Cleaning is performed directly within the equipment without disassembly, allowing the system to remain in operation or quickly return to service. Ideal for minimizing downtime in continuous production environments.
Employs high-frequency sound waves in a liquid bath to create microscopic cavitation bubbles that dislodge contaminants. Perfect for precision cleaning of small or complex components with hard-to-reach areas.
