Understanding Flux in Soldering
Flux is a crucial component in the soldering process, ensuring strong and reliable joints by removing oxidation, enhancing wetting, and preventing defects. Without flux, solder struggles to bond properly with metal surfaces, leading to weak connections and poor conductivity.
At Electo, we engineer advanced flux formulations designed to optimize soldering performance while ensuring long-term reliability. Our flux solutions, such as Electo PV 9190 and Electo PV 9050, are specifically developed to meet the stringent requirements of the electronics and solar industries.
Key Properties of Flux That Influence Soldering Efficiency
- Control of Total Acid Number (TAN) for Optimal Activation
The Total Acid Number (TAN) is a critical parameter in flux performance. It defines the flux’s ability to clean metal surfaces by breaking down oxides. A well-balanced acid number ensures effective cleaning without causing excessive corrosion.
Electo’s Approach: We maintain our flux formulations with an acid number around 16, aligned with international standards. This ensures sufficient activation without over-aggressive etching, preserving the integrity of delicate components.
- Anti-Corrosion Ingredients for Long-Term Reliability
While flux must be aggressive enough to remove oxides, it should also prevent corrosion that can compromise solder joints over time.
Electo’s Innovation: Our flux formulations incorporate specialized anti-corrosion additives, which neutralize acidic residues and provide long-term protection against environmental factors such as humidity and temperature fluctuations.
- Viscosity & Specific Gravity: The Role in Application and Performance
Flux viscosity determines its ability to flow evenly across the surface, while specific gravity impacts how it interacts with solder.
Viscosity Optimization: Our fluxes are engineered with controlled viscosity, ensuring smooth application through dispensing, brushing, or dipping processes.
Specific Gravity Control: Electo fluxes maintain optimal specific gravity, balancing ease of application with effective solder adhesion. This ensures consistent performance across different manufacturing processes.
- Refractive Index as a Performance Indicator
The refractive index of flux can indicate its chemical stability and effectiveness. It helps assess the purity and composition consistency, ensuring reliable results in high-precision soldering applications.
Electo’s Testing Standards: Our fluxes undergo rigorous refractive index testing to ensure high stability and performance consistency, meeting the demands of industries such as electronics, automotive, and solar panel manufacturing.
