Automotive PCBA Application Scenarios
1. EV Battery Management System
Widely used in new energy passenger vehicles and commercial vehicles,
the PCBA controls cell voltage sampling, temperature monitoring, charge-discharge
balance and high-voltage safety management, ensuring stable operation of power
battery packs and extending battery service life.
2. On-board Charging & Energy Conversion
Applied in on-board chargers (OBC) and DC/DC converters, the assembly supports
high-current power transmission and signal control, adapting to complex vehicle
electrical environments and meeting the reliability requirements of long-term charging
and power conversion scenarios.

Automotive PCBA Production Line
Our automotive-grade SMT production lines are equipped with high-speed
precision pick-and-place machines supporting 01005 component mounting,
and adopt nitrogen-protected vapor phase reflow soldering to ensure solder
joint reliability. The whole process is managed by MES system for full material
traceability, with strict control of temperature, humidity and ESD in the workshop.
All production processes follow IATF 16949 standards to deliver reliable automotive-
grade products.
