Wires for soldering performance, wettability and reliability

The Koki range of solder wires includes products to solve the key problems associated with hand soldering, wetting performance, bright shiny joints, low residues, minimal spattering and soldering iron tip life. These considerations together with high quality products offering high reliability and solder joint quality.

Specialist applications include: specialist alloys, automotive approvals.

Solder wires with high wettability, upto 4 x longer tip life

Low AgThe S03X7Ca-72M forms a barrier layer at the iron tip surface, which inhibits erosion of the tip. S03X7Ca-72M significantly reduces wear of iron tips compared to regular lead-free solder.

The standard lead-free solder, S3X-72M, and other 72M series products contain new activators for improved wettability and new resin composition for better flux coverage. They help prevent bridging, even in defect prone conditions such as low iron tip temperatures or fast sliding speed.

Up to 4 x longer iron tip life

  • Very fast wetting action
  • Very low residue
  • Minimal spattering
  • Low fumes
  • Clear residue
  • Suitable for robotic soldering applications

S01X7Ca-72M (0.1% Ag) and S03X7Ca-72M (0.3% Ag) form an IMG layer of Sn/Fe/Co between the solder and the iron tip. This inhibits tip erosion and greatly extends tip life.

Reliability, strength and thermal resistance

S1XBIG-72M, with very small amounts of Bi and Ni and low Ag content, helps achieve more reliable solder joints. Also offers superior melting, thermal fatigue resistance and stable crystal structure over time.

Superior strength and reliability for extreme conditions

SB6N-72M, with 6% Indium, improves strength and forms reliable solder joints. Ideal for extreme service conditions experienced typically in automotive electronics, aviation and industrial applications.

Halogen free, quality wetting solder wire

halogen freeKoki S3X-60NH, despite being halogen free, delivers excellent wetting performance and workability. Excellent anti-spatter performance.

  1. S3X-60NH quickly reacts to oxide films and spreads smoothly. The product removes stubborn oxide films even from brass and nickel at once, as well as from copper.
  2. While conventional halogen-free products tend to show poor wettability, S3X-60NH swiftly spreads to the whole pad surface and forms fine solder fillets.

S3X-60NH is ideal for solder wire applications applications requiring:

  • Anti-spatter
  • Decreased frequency iron-tip cleaning
  • Halogen-free
  • No clean
  • Powerful wetting
  • Suitability for robot soldering
