Application

Industrial Control

The industrial control industry includes core automation equipment such as PLCs, industrial robots, servo drives, and inverters. The equipment operates in environments with high-frequency vibration, temperature fluctuations, and high loads for extended periods, imposing stringent requirements on welding reliability.
Industrial Control

Application Features

  • Vibration-resistant and heat-resistant, joints remain solid without cracking
  • Low voiding with high thermal conductivity, suited to high-current applications
  • Oxidation-resistant with minimal residue, stable printing definition
  • Highly process-compatible, suited to continuous large-volume production

Industry Pain Points

Long-term equipment vibration leads to fatigue cracking of solder joints

High-power devices generate heat, and voids cause overheating failure

Temperature fluctuations and humidity in industrial control sites make solder joints prone to oxidation and corrosion

24-hour continuous production leads to large amounts of solder dross and high loss


Core Advantages

Vibration and Fatigue Resistant Solder Joints

Suitable for vibration, impact, and alternating high-low temperature working conditions. Solder joints are strong and impact-resistant, reducing cold solder joint cracking and lowering equipment failure rates.

High Power, Low Void, High Current Carrying Capacity

Suitable for soldering thick copper boards and power devices. Solder joints are dense with low voids, providing stable electrical and thermal conductivity to meet high-current, high-load usage requirements.

Industrial Grade Oxidation Resistance, Mass Production Compatible

Enhanced oxidation-resistant formula ensures stable Solder Paste printing, low dross generation in solder pots, and compatibility with 24/7 large-scale production for industrial control applications.

Wide Temperature Range Wetting Compatibility

Compatible with mixed SMT and through-hole component boards, suitable for both Reflow Soldering and wave soldering. Reduces solder bridging and cold solder joints, improving soldering yield.

Corrosion Resistant, Long Service Life

High solder joint density withstands humid, dusty, and salt spray environments, ensuring reliable long-term connection for industrial control equipment.

Batch Consistency Control

Full-process closed-loop testing ensures stable alloy composition, minimal batch variation, and compatibility with long-term mass supply for industrial control products.
