Professional-Grade RELIFE RL-420S UV BGA Flux Paste

The RELIFE RL-420S is a high-performance UV BGA flux paste formulated specifically for professional technicians. Its advanced composition improves solder wetting, enhances bonding strength, and minimizes common soldering issues such as cold joints, bridging, and oxidation.

This flux paste is suitable for a wide range of repair tasks, including:

• BGA rework and reballing

• Chip-level motherboard repairs

• SMD component soldering

• Micro soldering under microscope

• Precision PCB repairs

With its balanced viscosity and high activation formula, the RL-420S provides excellent control during application, allowing technicians to work accurately even on the smallest components.

High Activation Formula for Superior Soldering Results

One of the key advantages of the RELIFE RL-420S UV BGA flux paste is its high activation formula. This ensures rapid oxide removal and improved solder adhesion, resulting in strong, reliable solder joints.

Benefits of the high activation formula include:

• Faster solder melting and flow

• Improved wetting on pads and component leads

• Reduced soldering time

• Stronger and more durable connections

This makes the flux paste especially effective for leaded and lead-free soldering applications, ensuring consistent performance across different repair scenarios.

UV Traceability – Clean and Controlled Repairs

A standout feature of the RELIFE RL-420S is its UV traceability. The unique UV formula allows residue to be easily detected under UV light, helping technicians identify and clean leftover flux after soldering.

Advantages of UV traceability:

• Easy inspection of post-soldering residue

• Improved cleaning accuracy

• Reduced risk of hidden contamination

• Cleaner and more professional repair results

This feature is particularly valuable in high-precision repairs where even small amounts of residue can affect long-term circuit performance.

Low Residue, No Corrosion & Low Smoke Formula

The RELIFE RL-420S UV BGA flux paste is designed with safety and board protection in mind. Its low residue formulation minimizes cleanup time while ensuring the PCB remains clean and functional.

Key safety and quality features include:

• Non-corrosive composition

• Safe for delicate PCB tracks and pads

• Low smoke during heating

• Reduced risk of board discoloration or damage

This makes it ideal for sensitive electronics and high-density circuit boards commonly found in modern smartphones, tablets, and other electronic devices.

Smooth Consistency for Precision Application

Consistency matters when working on micro-level repairs. The RL-420S flux paste has a smooth, well-balanced texture that allows precise application without spreading uncontrollably.

This ensures:

• Accurate placement on BGA pads and SMD points

• Better control under microscope

• Reduced wastage of flux paste

• Cleaner working environment

Whether applied with a syringe, spatula, or fine tip tool, the flux stays exactly where it is needed.
