Is SN100C fully RoHS compliant?

Yes, it's lead-free and meets all RoHS, REACH, and ELV standards.

What is the composition of SN100C?

Tin (Sn): Balance; Copper (Cu): 0.60 - 0.70%; Nickel (Ni): 0.04 - 0.06%; Germanium (Ge): 0.005 - 0.01%. Maximum impurities: Lead (Pb) 0.05%, and others as per industry standards.

What are the minimum order quantities?

20kg for direct from DKL; smaller quantities available via Surclean.

How do I get pricing?

Contact using one of the methods below—a member of our sales team can give you a quote.

In what product formats is SN100C solder available?

SN100C is available in 1kg bars, 2kg and 3.8kg autofeed ingots, chunks, and pellets. We also supply 125g and 250g tinman sticks, as well as blowpipe solder for specialist applications.

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 recommended storage temperature for Cobar OT2 solder paste?

After receiving your solder paste from DKL Metals, it should immediately be stored between 8 °C and ambient room temperature. Unlike traditional pastes, DO NOT store Cobar OT2 in a standard refrigerator or below 8 °C, as low temperatures can compromise the stability of this specific chemistry. Always store cartridges horizontally and rotate them monthly to eliminate flux segregation.

Do I need to clean Cobar OT2 no-clean flux residues after reflow?

No. Cobar OT2 is a true no-clean formula. The clear residues remaining on the printed board assembly (PBA) after soldering are completely chemically inert, non-conductive, and safe to leave on the board. However, if cosmetic cleaning or subsequent conformal coating is required, residues can be removed using Cobar MCA-1424 aqueous cleaner. Misprints and stencil tools can be cleaned with MCI-2330.

How do I prevent graping and head-in-pillow defects with OT2 flux?

The Cobar OT2 platform features an advanced activator system specifically engineered to eliminate graping and head-in-pillow (HiP) defects during reflow. To maximize its effectiveness on poor-wetting board finishes, utilise a linear reflow profile. Ensure your flux activation time (FAT) between 150 °C and 200 °C remains between 20 to 150 seconds, with a peak reflow temperature between 240 °C and 260 °C.

What are the optimal printer squeegee settings for high-speed SMT lines?

Printing speeds between 25–100 mm/s, apply a squeegee pressure of 0.20 kg/cm. For high-speed SMT printing between 100–200 mm/s, increase pressure slightly to 0.25 kg/cm. It is recommended to decrease pressure by 5% for every 1 °C rise in ambient temperature above 23 °C. If your printing line halts for more than 4 hours, a total stencil clean is highly recommended before restarting.

How does SAC0307 compare to SAC305 in terms of cost and performance?

SAC0307 contains significantly less silver (0.3% vs 3.0%), making it a much more cost-effective alternative to SAC305. While it offers a slightly higher melting range, its wetting performance is comparable to SAC305 in most standard wave soldering applications.

What is the optimum operating temperature for a LowSAC bath?

The recommended operating temperature is 265°C ± 5°C. Operating at this temperature ensures excellent through-hole penetration and fast wetting while maintaining the stability of the alloy's fluidity during dynamic wave soldering.

How should I manage copper build-up in the solder pot?

Lead-free alloys naturally dissolve copper from PCBs. To keep copper levels within the recommended 0.6%–0.8% range, use LowSAC Type Ye copper-free top-up alloy. Regular bath analysis is essential to determine when a partial drain or top-up is required.

Is LowSAC Type Y compatible with my current flux?

Yes, this alloy is designed for high compatibility. It works effectively with low-solids, no-clean, and VOC-free flux formulations. Always refer to your flux manufacturer's data sheet to ensure the pre-heat and contact times are optimized for a 228°C liquidus.

Why does SAC alloy joints look dull compared to tin/lead?

This is a natural characteristic of lead-free SAC alloys. Due to the inherent grain structure and cooling rates, joints will appear more matte or dull than traditional SnPb joints. This does not indicate a sub-standard or weak connection; it is purely a visual difference.
