Tinspole SN100C® – SnCu0.7Ni StarCore®234E ROL0 0.8 mm 400 g
SN100C® StarCore®234E is a professional lead-free solder wire from Balver Zinn, developed for hand soldering, rework, and electronics production, where high demands are placed on solder quality, process stability, and reliability. The combination of the well-documented SN100C® alloy and the halogen-free StarCore®234E ROL0 flux provides uniform solder joints, efficient wetting, and a clean soldering result.
The 0.8 mm wire diameter makes the solder wire particularly suitable for general electronics assembly, printed circuit board repair, and daily soldering tasks in production, development, and service departments.
SN100C® – a documented lead-free solder alloy
SN100C® is a eutectic tin-copper alloy stabilized with nickel and added germanium. The alloy is designed to reduce oxidation during the soldering process and is today among the most widely used lead-free alternatives to traditional silver-containing solder alloys.
Its composition contributes to stable soldering properties, lower material consumption, and excellent solder joints with high mechanical strength. At the same time, germanium helps reduce the oxidation of the solder, which supports a more stable and economical soldering process.
StarCore®234E ROL0 flux for optimal solder quality
StarCore®234E is a halogen-free No-Clean flux classified as ROL0 according to IPC J-STD-004. The flux is developed for modern lead-free soldering processes and provides rapid activation, efficient wetting, and good flow properties.
The result is uniform solder joints with minimal flux residues and high process stability. The flux system is developed for professional electronics environments where both quality and reliability are crucial.
Ideal for electronics production, rework, and service
The popular 0.8 mm diameter makes this solder wire a versatile choice for many types of soldering tasks:
