Automotive NEV Electronics

Overview

Driven by fast‑growing penetration of new‑energy vehicles, vehicle intelligence brings explosive growth for automotive‑grade electronic components. On‑board electronics operate under highly variable service conditions and must comply with strict automotive qualification standards. Solder interconnections serve as critical safety‑related links for vehicle electronic systems.

Core Application Scenarios

• Battery Management System (BMS)

• On‑board charger and vehicle control units

• Automotive power modules and motor controllers

• Domain controllers and on‑board sensors

Key Technical Challenges

• Endure repeated wide‑range temperature cycling in real‑vehicle environments

• Solder joints shall resist fatigue and creep under continuous vibration and mechanical shock

• Pass comprehensive validation including high‑temperature aging, humidity and salt‑spray tests

• Minimize corrosive risks to prevent in‑service electronic failures

Solutions

Huaqing’s automotive‑grade solder series features tightly‑controlled impurity levels and reliability‑optimized alloy compositions. The products have undergone systematic verification of temperature cycling, high‑temperature storage, damp‑heat and vibration tests. Formulated for superior wetting performance, our materials produce mechanically robust solder joints with excellent creep‑resistance, supporting joint debugging and validation for customers’ automotive projects.
