STIRRI® Sn100Ge: Ultra-Pure Selective Solder Wire

STIRRI Sn100Ge is a premium, micro-alloyed lead-free solder wire engineered for high-reliability selective soldering. Formulated with a specific Germanium (Ge) anti-oxidant additive, this alloy provides the high-luster "shiny" joints and superior wetting typically only seen in leaded alloys.

Direct Functional Equivalent

STIRRI Sn100Ge is a drop-in, seamless substitute for the industry's most trusted micro-alloyed compositions. If your process is qualified for the following, Sn100Ge is a direct replacement:

• SN100C® (Nihon Superior / AIM Solder)
• NT100Ge (FCT Assembly)
• Indalloy 291 (Indium Corporation)
• K100LD (Kester)

Why Engineers Specify Sn100Ge (Sn/Cu/Ni+Ge):

• The "Ge" Advantage: Germanium micro-additives prevent dross formation and oxidation, ensuring bridge-free performance in selective solder fountains.
• Nickel-Stabilized (Ni): Dramatically reduces copper leaching (dissolving of PCB pads) during long dwell times.
• 227°C Eutectic-Like Behavior: Offers superior "flow" and hole-fill compared to standard SAC305.

Technical Specifications

Industrial Compliance: Metal Traceability and CMART documentation are maintained for all STIRRI alloys and are available along with certificate of analysis and compliance (COA, COC).
