Key Features
1. High-Performance Synthetic Rosin Formula
The YCS Solder Flux Paste is formulated with premium synthetic rosin, which improves solder wetting and enhances adhesion to copper traces and metal surfaces. This specialized formula ensures optimal solder flow, resulting in smooth, uniform joints with minimal bridging.
2. Improves Soldering Efficiency
By reducing surface tension, this flux paste allows molten solder to spread evenly, creating clean and reliable connections. It effectively minimizes solder balling and ensures precise bonding, especially in delicate SMD and BGA soldering applications.
3. Strong Anti-Oxidation Properties
The YCS Flux Paste prevents oxidation on PCB pads and component leads by forming a protective layer that shields metal surfaces from air exposure. This results in better conductivity and increased durability of soldered connections.
4. Non-Corrosive and Residue-Free
This synthetic rosin flux is formulated to leave minimal residue, ensuring clean and professional-looking solder joints. The non-corrosive formula eliminates the need for aggressive cleaning after soldering, saving time and effort.
5. Enhanced Heat Resistance
The YCS Flux Paste is designed to withstand high soldering temperatures, ensuring consistent performance without burning or degrading. This feature is particularly useful in complex PCB repairs and BGA rework, where controlled heat application is crucial.
6. Ideal Viscosity for Precision Application
The paste’s smooth consistency ensures easy and precise application. Whether you’re using a brush, syringe, or flux pen, the YCS Solder Flux Paste flows evenly and adheres effectively to target areas without excessive spillage.
7. Suitable for Various Soldering Techniques
The YCS Flux Paste is compatible with multiple soldering methods, including:
✅ Hand Soldering
