Solder Materials
We've been making microelectronic soldering materials for over twenty years. Our solder product line includes solder wire, solder bars, and preformed solder preforms, mainly used in PCBA mounting, structural component soldering, and semiconductor packaging.

The Challenge
What's the biggest fear with solder wire? Core breakage. Uneven rosin distribution—the wire feeds halfway and suddenly breaks, forcing the automated line to stop for troubleshooting.
Our Solution
We added real-time rosin content monitoring to our production process, a technology that earned a national invention patent. In actual use, robotic soldering can run continuously for several hours without issues, suitable for high-speed production lines.
Alloy Systems
Our alloy systems include conventional formulas like Sn63Pb37 and Sn96.5Ag3.0Cu0.5—we can do both leaded and lead-free.
Customization
Wire diameter and rosin ratio can be customized to customer requirements, not just standard specifications.
Quality Control
Impurity content is tightly controlled, with good fluidity after melting and minimal oxidation dross.
Usage Scenarios
Solder bars use the same alloy formulas as solder wire, suitable for both wave soldering and selective soldering. The resulting solder joints have guaranteed mechanical strength and conductivity.
Preformed Solder Preforms
For connectors, sensors, power modules and such, soldering position and solder volume requirements are very precise—preformed solder preforms are made for this.
Shapes: Round, square, ring-shaped, irregular
Thickness: From 0.05mm up
Process: Just provide drawings
Flux: Coating amount is controllable
Residue: Minimal, no cleaning needed
Void Rate: Kept low for heat dissipation
Consistency: Fixed solder volume
Yield: Stable in mass production
Why it matters
Customers making power devices pay close attention to void rate—more voids mean worse heat dissipation. We keep this metric quite low through powder particle size and flux formulation. Unlike manual dispensing which varies, preforms ensure high consistency.
Key Industries
Widely used in industries with high consistency requirements like automotive electronics, photovoltaics, and communications.
How to Collaborate
Company headquarters is in Shenzhen with a technical team. Tell the engineers your soldering process parameters, substrate type, usage environment and such, and they'll recommend models or help with custom development.
