PowerMax Pro is a double-sided, ENIG (Electroless Nickel Immersion Gold) finished PCB engineered for high-efficiency power management systems.
Featuring 2-oz copper thickness, ultra-precise impedance control (±5%), and customizable layouts, it delivers superior thermal management and electrical stability for industrial, automotive, and renewable energy applications. 
 

Unlock Next-Gen Power Efficiency with Precision Engineering
In the era of electrification, power management PCBs must balance high current handling, miniaturization, and reliability. PowerMax Pro addresses these challenges through advanced 2L ENIG technology. Our double-sided PCBs utilize 2-oz copper layers to reduce resistive losses by up to 30% compared to standard 1-oz designs, enabling efficient heat dissipation in compact spaces like EV battery controllers and server PSUs. 
 

Key Technical Innovations:

HDI-Compatible Design:
Supports 3/3 mil trace/space with laser-drilled micro-vias (0.1mm), allowing 40% higher component density for space-constrained applications like drone motor drives.

Material Excellence:
FR-4 high-Tg (170°C) base with ENIG surface finish ensures solder joint integrity under thermal cycling (-55°C~150°C), critical for automotive ADAS modules. 
 

Signal Integrity Focus:
Impedance control at ±5% tolerance through ANSYS-simulated stackups, minimizing EMI in RF power stages.
 

Customization at Core:
From rapid prototyping (72-hour samples) to volume production, we support:

Layer-specific copper weights (1–12 oz)

Mixed-material stacks (e.g., Rogers 4350B for RF + FR-4 for power planes)

Blind/buried vias for 3D routing optimization

Ideal for: 5G base station rectifiers, industrial servo drives, and solar microinverters demanding high-end PCB reliability.
 

Why Engineers Choose PowerMax Pro:

✅ 30% Higher Current Capacity
2-oz copper + ENIG coating enables 12A/mm² current density (vs. 8A/mm² in standard PCBs), reducing hotspots in BMS boards. 

✅ Zero-Failure Durability
IPC Class 3-certified manufacturing with 100% AOI/flying probe testing eliminates opens/shorts, achieving 99.2% field MTBF over 5 years. 

✅ Thermal Management Mastery
Copper-core thermal vias transfer heat 4x faster than conventional designs, slashing junction temperatures by 15°C in 100W+ PSUs. 

✅ Agile Customization
Parametric-driven design tools allow real-time DFM feedback—adjust trace widths, dielectric layers, or finish types (OSP/Immersion Silver) in 24 hours.

✅ Cost-Smart Scaling
Hybrid material layouts (e.g., aluminum substrates for LED drivers) cut system costs 20% while meeting UL94V-0 flame ratings.
