2UUL SF99 Union Repair No-Clean Soldering Flux Paste – Reliable Performance for PCB & Mobile Repairs
In professional electronics repair, achieving a strong, clean, and reliable solder joint is the foundation of success. Whether you are replacing IC chips, fixing broken PCB pads, or handling delicate mobile phone components, the right flux can determine whether your repair is flawless or fragile. The 2UUL SF99 Union Repair No-Clean Soldering Flux Paste is engineered to give technicians a high-performance, lead-free, halogen-free solution that ensures consistent, high-quality soldering results without the hassle of extensive cleanup.
Packaged in two 10 ml tubes, this flux paste offers convenience, portability, and efficiency, making it an essential tool for repair professionals and electronics enthusiasts alike.
What is 2UUL SF99 No-Clean Flux?
Flux is a chemical compound applied before soldering to clean metal surfaces, remove oxidation, and improve the flow of molten solder. A high-quality flux ensures strong electrical conductivity, reduces rework, and prevents weak joints.
The 2UUL SF99 No-Clean Flux Paste takes these benefits to the next level by offering a no-clean formulation. Unlike conventional flux that often leaves behind sticky or corrosive residues requiring post-solder cleaning, this advanced flux minimizes residue and leaves behind a clear, non-conductive, and safe finish. This saves time, improves efficiency, and protects delicate circuit boards.

Why Choose 2UUL SF99 Over Standard Flux?
Not all flux products are created equal. Many low-quality alternatives leave corrosive residues, cause poor solder flow, or even damage sensitive boards. The 2UUL SF99 is designed specifically for modern electronics and addresses these common issues:
-
Residue-Free Performance – Unlike traditional flux, SF99 dries clear without leaving sticky or corrosive buildup.
-
Safe for Sensitive Electronics – With a lead-free, halogen-free formula, it is safe for smartphones, laptops, and consumer devices.
-
Time-Saving Efficiency – The no-clean formulation reduces the number of steps in your workflow.
-
Professional Finish – Ensures clean, reliable solder joints that meet industry standards.
Applications
The 2UUL SF99 No-Clean Flux Paste is a versatile solution for a wide range of soldering jobs, including:
-
Mobile Phone Repairs – Perfect for soldering connectors, charging ports, and IC chips on motherboards.
-
PCB Rework – Cleans and prepares pads for component replacement or reinstallation.
-
BGA & IC Reballing – Ensures strong adhesion during chip soldering and reballing processes.
-
Fine-Pitch Components – Assists in soldering tiny components like SMD resistors, capacitors, and transistors.
-
General Electronics – Suitable for laptops, tablets, gaming consoles, and other consumer electronics.
How to Use
-
Apply Flux – Squeeze a small amount of flux paste onto the target area (pad, pin, or joint).
-
Heat & Solder – Use a soldering iron or hot air gun to melt solder while the flux improves flow and adhesion.
-
Minimal Cleanup Needed – Since it’s a no-clean flux, you can leave most joints as is. If desired, wipe with isopropyl alcohol.
Advantages for Repair Technicians
-
Improved Workflow – Less time wasted on post-solder cleaning.
-
Reduced Failures – Stronger joints mean fewer returns and rework.
-
Cost-Effective – Each 10 ml tube goes a long way, making it economical for professional shops.
-
Portable & Easy to Store – Compact tubes are easy to keep in your repair kit or workstation.
