Qinji 10-Layer 1+1 HDI Board for New Energy Power Electronics

In the field of new energy power electronics (PV / energy storage / EV charging piles), PCBs are subject to extremely high requirements for precision, reliability and integration density. The 10-layer 1+1 HDI board launched by Qinji  PCB Cloud is a high-performance solution designed to meet these stringent demands.

Core Technical Specifications

Product Advantages

Ultra-Precision for High-Density Integration

With a minimum aperture of 0.1 mm and minimum BGA pitch of 0.2 mm, this PCB supports highly compact component placement, perfectly matching core control modules in new energy equipment that demand strict space and performance constraints.

High-Reliability Materials for Harsh Environments

Built with Shengyi S1000-2M base material (TG170), it features outstanding thermal resistance and mechanical strength, ensuring long-term stable operation in high-temperature, high-humidity and high-vibration environments typical of new energy applications.

Advanced Processes for Signal Integrity

Immersion gold + gold fingers (30μ") deliver excellent corrosion resistance and electrical conductivity, guaranteeing stable transmission of critical signals. Resin plug-hole and electroplating filling technology effectively improve surface flatness, providing a reliable foundation for high-density surface mounting.
