The Workhorse of Gestión térmica
Aluminum PCBs power over 70% of all metal-core applications worldwide. Our aluminum substrate delivers reliable thermal management at a price point that makes economic sense from prototype to mass production. With 1–10 layer capability and four structural configurations, we cover everything from simple LED boards to complex power modules.
Stack-Up & Process Under One Roof
We offer diverse MCPCB stack-up configurations backed by full fabrication processes. Structures including metal sandwich, Cu-Al hybrid and thermal-electric separation satisfy varied thermal & mechanical requirements.
Stack-Up Configurations
4 structural architectures for every thermal scenarioMetal Sandwich
Symmetrical Thermal Design
Double-sided circuits on both sides of metal core. Symmetrical heat dissipation, max rigidity.
Single-Side Multi-Layer
HD Single/Double-Sided Stack-Up
Multi-layer circuit pressed onto one side of metal core. Up to 10 layers on Al or Cu substrates.
Cu-Al Hybrid
Cost-Performance Balanced
Copper thermal layer bonded to aluminum base. Near-copper performance at a fraction of the cost.
Thermal-Electric Separation
Ultimate Thermal Performance
Components directly on copper core — zero dielectric barrier. Unlocks full 385 W/mK.
Core Processes
4 precision manufacturing techniquesPTH vias connect circuits on both sides of metal core. Higher density, dual-side placement.
FR4 layers pressed above metal core. Up to 10 layers for complex routing with thermal grounding.
FR4 and metal substrate co-laminated on one panel. Zoned thermal for cost optimization.
0.5-4 oz copper traces for high-current power. Extreme thermal + electrical load for EV/IGBT.

It depends on your thermal budget, application environment, and cost targets.
- Aluminio (1-10 W/mK, 1-10 layers) handles 80% of applications — LED, consumer, power supplies — at the best price.
- Cobre (2-385 W/mK, 1-10 layers) is for extreme heat: automotive, IGBT, EV charging.
- Iron (1-2 W/mK, 1-2 layers, μ>200) is for specialty magnetic/EMI applications.

We manufacture four structures:
- Metal Sandwich — circuits on both sides, ideal for double-sided assemblies.
- Single-Side Multi-Layer — up to 10 layers on one side, for complex routing.
- Cu-Al Hybrid — copper thermal layer on aluminum base, best cost-performance ratio.
- Thermal-Electric Separation — direct metal contact without dielectric, unlocks full 385 W/mK for maximum heat dissipation.
Our engineers will recommend the right configuration based on your thermal simulation and budget.
We support four core process technologies:
- Doble Cara — circuits on both sides with PTH vias.
- Multi-Layer Sandwich — FR4 layers pressed above metal core, up to 10 layers.
- Laminación Híbrida — FR4 and metal substrate co-laminated on the same board for zoned thermal management.
- Heavy Copper — up to 4 oz for high-current power delivery.
All processes are done in-house — no outsourcing.
Prototyping starts at just 5 pieces per design across all three substrates.
Production runs typically begin at 100 pieces, but we also accommodate low-volume production for specialized projects.
No minimums for registered customers on their first order.
- ENIG (gold) — best for fine-pitch and long shelf life.
- HASL-LF (lead-free) — cost-effective for through-hole.
- OSP — budget option for quick-turn.
- Immersion Silver — excellent for high-frequency.
We recommend ENIG for most metal core applications.
Prototyping: 24-48 hours for all three substrates.
Production: 5-7 business days.
Shipping via DHL/FedEx: 3-5 days to North America/Europe, 2-3 days within Asia.
Same-day expedited available for aluminum prototypes.
