Is the LF2220NC suitable for automated soldering?

Primarily formulated for hand soldering and manual rework. For high-heat automated processes, LF3135NC is recommended due to its specific high-temperature activator profile.

How is the flux classified, and is it halide-free?

Classified as REL0 (EN 61190-1-1) and REL0 (J-STD-004). Genuine halide-free, no-clean rosin-based formulation designed for low corrosion risk applications.

What is the shelf life of this wire?

Minimum 2 years when stored in a clean, dry environment at room temperature.

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.

Does EQ-STD solder wire require cleaning after use?

No, EQ-STD is a true 'no-clean' solution. It is formulated with modified rosins that leave a transparent, non-corrosive residue, eliminating the need for post-solder washing and ensuring long-term reliability.

Does this solder 'spit' or 'crackle' during use?

EQ-STD is engineered for minimal spatter. If you experience 'spitting,' it is often caused by moisture absorption in the flux core due to high humidity. Always store your spool in a dry, cool environment (below 22°C and 80% RH) in its original container to prevent this.

Can I use this for plumbing or heavy-duty repairs?

No. This is a rosin-based electronics solder. It should never be used for plumbing, as it does not contain the aggressive acid fluxes required for water pipes. Conversely, plumbing flux should never be used on PCBs as it will corrode electronic traces.

How do I know which wire diameter to choose?

The best diameter depends on your component size: 0.3mm-0.5mm is ideal for high-density SMT; 0.7mm-1.0mm is the standard for general through-hole and hobbyist work; 1.2mm+ is best for large connectors and heavy-gauge wires.

Is it safe to leave the residue on the board?

In most standard electronics applications, yes. EQ-STD is designed to leave a low-residue, non-corrosive finish under normal operating conditions. Cleaning is recommended for high-frequency circuits, aerospace or other high-reliability assemblies, and any project where residue removal is required for conformal coating or visual inspection.

What are the safety requirements for handling leaded solder?

When using leaded variants (like 60/40), avoid eating, drinking, or smoking in the work area. Always use fume extraction to avoid inhaling flux vapours and wash your hands thoroughly after use to prevent lead absorption.

What is the best lead-free solder for automated selective soldering?

For most automated selective soldering applications, SN100C and SAC305 (97TSC) are the industry standards. SN100C is highly valued for its lower copper dissolution and smooth, bright joints, while SAC305 offers higher tensile strength. SAC300 is often used as a replenishment alloy to balance copper levels. The choice depends on your specific thermal profile requirements and assembly standards.

Why should I use solid solder wire instead of flux-cored wire for pot top-ups?

Using solid solder wire for automated top-ups prevents flux build-up in the solder pot. Since the pot already contains liquid flux applied during the process, adding cored wire would shift the chemical balance and lead to excessive dross and contamination.

How do SN100C and SAC305 compare in terms of copper dissolution?

SN100C is specifically engineered to minimise copper leaching (dissolution), making it ideal for thin copper pads and high-reliability electronics. SAC305 has a slightly higher rate of copper dissolution but provides superior creep resistance and tensile strength (52 MPa) for high-stress environments.

What are the reel specifications for robotic soldering wire feeders?

Our lead-free auto-feed wires are supplied on DIN K125 plastic reels, weighing 4kg as standard. This format is compatible with the majority of selective soldering machines.

Is selective soldering more cost-effective than wave soldering?

Yes, by eliminating the need for expensive aperture pallets, reducing solder dross by up to 90%, and lowering nitrogen and electricity consumption, it offers a much lower cost-per-joint for PCB assemblies.

What wire diameters are standard for selective soldering top-up systems?

Standard diameters for automated top-up systems are 2.0mm and 3.0mm. These sizes allow for a fast, controlled melt rate that quickly replenishes the solder pot without significantly dropping the temperature of the molten alloy.

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.

Standards Compliant

Complies with BS 441 Rosin Class 5B, DTD 599A, and QQS 571E-RMA, aligning with widely recognised international standards for rosin-based fluxes.

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.
