Core Values

Guided by the principle of “Quality for Survival, Stability for Development,” Lingsko is committed to delivering high-quality, reliable solder powder products that meet the needs of customers worldwide, striving to become a recognized global brand in the tin-based alloy solder powder industry.

The Lingsko Process

From raw alloy to certified solder powder — a fully enclosed, inert-atmosphere production system engineered for batch-to-batch consistency.

Induction Melting
Raw Material & Alloying
High-purity Sn, Ag, Cu and other base metals are precision-weighed and melted to exact alloy composition in a controlled induction furnace.
N₂ Inert Atmosphere
Ultrasonic Atomization
Molten alloy is converted into fine, spherical droplets using high-frequency ultrasonic energy under N₂ inert atmosphere — producing powder with superior sphericity and low oxidation.
Type 3 – 7
Sieving & Classification
Solidified powder is classified by vibratory sieving and air classification into Type 3–7 grades, with tight particle size distribution verified by particle size analysis.
ICP-OES · SEM · O₂
QC & N₂ Packaging
Every batch is tested in our in-house laboratory — ICP-OES composition analysis, SEM morphology inspection, and oxygen content testing — before being sealed in nitrogen-purged jars with full Certificate of Analysis.

Global Scale & Capacity

With an annual production capacity of 1,200 tons, Lingsko delivers high-purity solder powder at scale — covering lead-free SAC alloys, low-temperature SnBi series, tin-lead grades, and high-temperature formulations. Our fully enclosed atomization system maintains strict alloy composition and particle size control across every production run.

Quality & Compliance

Every batch of solder powder is manufactured and tested to IPC J-STD-005 / J-STD-006 and REACH standards, and all lead-free grades are RoHS compliant. Our quality system combines SPC-driven process control with verification in our own in-house laboratory — no batch ships until it has been tested and released by our lab.

Our manufacturing facility is certified to:
✓
ISO 9001
✓
ISO 14001
✓
ISO 45001

SPC-Driven Consistency

Statistical Process Control is embedded into every stage of alloy preparation and atomization, minimizing batch-to-batch variation in composition, particle size, and sphericity across all alloy grades and production lots.

Quality Control Laboratory

We operate a dedicated in-house Quality Control Laboratory equipped for ICP-OES alloy composition analysis, particle size distribution analysis, SEM morphology inspection, and oxygen content testing. Every production lot is tested in-house, with a full Certificate of Analysis issued for each shipment.
