Flux Cleaner ｜ How to Reduce Leakage Current in Circuit Boards
Proper removal of flux residue is essential to reduce leakage current and extend the life of circuit boards used in automotive, medical, and aerospace industries.
■ Residual Flux – The Invisible Risk on Circuit Boards
Flux improves soldering, but any residue left can silently damage circuits by causing:
・Leakage current
・Corrosion
・Low insulation resistance
・Reduced reliability
For industries requiring high-reliability electronic components, such as automotive and aerospace, flux residue is a critical risk that must be managed.
■ Key Principles of Effective Flux Cleaning
To ensure long-term reliability, your cleaning process should include:
1. A flux cleaner suited to the flux type
2. Technologies like ultrasonic cleaning (ระบบอัลตราโซนิก)
3. Final drying and cleanliness inspection
■ Properties of a High-Quality Flux Cleaner
When selecting a cleaning agent, prioritize the following:
・Effectively dissolves flux without residue
・Non-corrosive to sensitive components
・Fast-drying, low-flammable, and safe for users
・Environmentally friendly
・Compatible with automation and ultrasonic cleaning systems
Always match the cleaner to your flux type: Rosin, No-Clean, or Water-Soluble.
■ Post-Cleaning Cleanliness Inspection – A Must for Reliability
Microscopic inspections and Surface Insulation Resistance (SIR) testing ensure no residue remains and help maintain long-term performance.
■ Product Recommendation: EClean 21F-6 by Kaneko Chemicals (Thailand) Co., Ltd.
EClean 21F-6 is specially formulated to clean JS-E-15X and other flux types effectively.
Key benefits:
・Highly effective with ultrasonic systems
・Air-dries, no heating required
・Non-corrosive and component-safe
・Leaves no visible residue under microscopy
Ideal for factories prioritizing PCB cleanliness and product reliability.
