Is LF3135NC suitable for automated soldering?

Yes. Balver Zinn specifically recommends this wire for manual, robotic, and repair soldering. The activator has an increased decomposition temperature, which ensures optimum results even with low flux content during high-heat automated processes.

How is the flux classified?

The flux is classified as REM1 (EN 61190-1-1) or RoM1 (J-STD-004). It is a halide-containing, rosin-based formulation that provides higher activation for difficult soldering tasks while remaining a true 'no-clean' product.

What is the shelf life of this wire?

When stored in a clean, dry environment at room temperature, LF3135NC cored solder wires have a minimum shelf life of 5 years.

Is Clearflow L0 truly halide-free and what tests does it pass?

Yes, Clearflow L0 is truly halide-free. It passes SIR (IPC-TM-650 2.6.3.3), Electro Migration (Bellcore GR-78), Copper Corrosion (IPC-TM-650 2.6.15), and Copper Mirror (IPC-TM-650 2.3.32) tests.

Do I need to clean Clearflow L0 residues after soldering?

No. It's a true no-clean flux. Residues are minimal, clear, non-tacky, and non-corrosive—no post-solder cleaning is required where the process allows.

What standard reel sizes are available?

Standard reel sizes include 0.25kg, 0.5kg, 2.5kg, 3kg, 5kg, 10kg, 15kg, and 25kg. Custom packaging is available on request.

What is the guaranteed shelf life?

Clearflow L0 has a 4-year guaranteed shelf life when stored in dry conditions between 10°C and 40°C. It has an indefinite shelf life with proper storage conditions.

What alloys pair with Clearflow L0?

Lead-free alloys like Sn100C and SAC305 pair perfectly with Clearflow L0.

No-Clean and Halide-Free

DKL Clearflow L0 wire is a no-clean, halide-free cored solder wire manufactured using a unique modified rosin flux system. It leaves minimal clear residue, generates no offensive odours during soldering, and is designed for high-reliability electronic assemblies where post-solder cleaning is undesirable or impractical.

Halide Free

Formulated without halides to meet ROL0 requirements under J-STD-004B, Clearflow L0 is ideal where long-term reliability and freedom from corrosion are critical.

Clear Residue

The modified rosin system produces an absolute minimum of clear, non-tacky residue, offering an excellent cosmetic finish and helping maintain high surface insulation resistance.

High Reliability

Clearflow L0 passes surface insulation resistance, electro migration, copper mirror, and copper corrosion tests, supporting robust performance in demanding electronic environments.

Typical Applications

DKL Clearflow L0 Wire is suitable for manual and robotic soldering of a wide range of electronic assemblies, including through-hole joints, rework operations, and fine electronic repairs where a no-clean, low-residue solution is preferred.

Its halide-free formulation and strong electrical reliability make it particularly attractive for high-reliability sectors such as industrial controls, instrumentation, and communication electronics.

Handling and Storage

To achieve the best performance, store Clearflow L0 in dry conditions between 10°C and 40°C and keep reels in their original packaging until use.

Under these conditions the product carries a guaranteed shelf life of 4 years and can remain usable for much longer when stored correctly.
