Industrial Power & Automation

Overview

Industrial power and automation equipment is trending toward higher power density and non‑stop long‑duration operation. Power‑intensive components generate substantial heat during service; thermal cyclic stress continuously acts on solder joints, making joint strength and anti‑fatigue capability decisive factors for equipment service lifetime.

Core Application Scenarios

• Inverters and servo drivers

• Industrial power supply modules

• PLC main control boards

• Power conversion assemblies

Key Technical Challenges

• Resist thermally‑induced creep and fatigue under long‑term cyclic thermal stress

• Achieve satisfactory wetting performance for heavy‑copper PCBs and large‑area pads

• Keep void ratio at low level to reduce thermal resistance of power‑device joints

• Adapt to mixed production processes including reflow and wave soldering

Solutions

Huaqing supplies high‑strength solder pastes, pre‑formed solder foils and industrial‑grade fluxes for heavy‑power scenarios. Optimized alloy systems enhance joint anti‑creep and thermal‑fatigue resistance. Our materials realize low‑void interconnection for large pads and heavy‑copper boards, lowering thermal resistance for efficient heat dissipation. They are fully compatible with mainstream industrial soldering processes for mass manufacturing.
