Aluminum PCBs, also known as Aluminum Base PCBs or Aluminum Core PCBs, are specialized Printed Circuit Boards (PCBs) that use an aluminum alloy as their foundational material instead of traditional FR-4. This unique construction provides superior heat dissipation compared to conventional boards, making them indispensable for electronics operating in high-temperature environments.
A TriWin Aluminum PCB typically features three precisely engineered layers:
Circuit Layer: This layer consists of copper foil (commonly 1–4 oz thickness) that forms the electrical pathways. It’s designed to reliably handle high current-carrying capacity.
Dielectric Layer: A thin, thermally conductive insulating layer, often made from specialized epoxy resin filled with aluminum oxide and silicon powder. It offers low thermal resistance (e.g., 1–2°C per watt for a 1.5mm thickness), effectively transferring heat from components to the aluminum base while maintaining crucial electrical isolation.
Aluminum Base: The robust aluminum layer (typically Aluminum 5052, 6061, or 1060) serves as the primary heat sink and provides essential structural stability. This base significantly enhances overall heat dissipation and offers good machinability.
At TriWin, we manufacture high-quality Aluminum PCBs that meet the rigorous demands of modern electronics, ensuring stable operation and optimal performance in thermally challenging conditions.

Key Advantages of TriWin Aluminum PCBs
Choosing TriWin’s Aluminum PCBs offers numerous benefits, providing a strategic advantage for your electronic designs
Efficient Heat Dissipation: Our aluminum PCBs effectively transfer heat away from critical components. This helps reduce operating temperatures, extends component lifespan, and can often reduce or eliminate the need for bulky external heat sinks, leading to more compact and lighter designs.
Cost-Effectiveness: Aluminum PCBs are generally more affordable than copper or stainless-steel-based PCBs. This makes them an ideal and economical choice for high-volume production where robust thermal management is required without the premium cost of copper.
Enhanced Durability & Mechanical Stability: Aluminum’s inherent high mechanical strength (elastic modulus: 72,000 MPa) provides excellent resistance to both thermal and mechanical stress. This ensures long-term reliability and minimizes breakage, making them suitable for robust applications.
Lightweight Construction: Aluminum is considerably lighter than copper, contributing to the overall lightweight design of your final product. This is beneficial for applications where weight is a critical factor.
Environmental Friendliness: Aluminum is fully recyclable and non-toxic, aligning with RoHS standards and supporting sustainable manufacturing practices.
Excellent Dimensional Stability: Aluminum PCBs maintain good size stability (typically 2.5%–3.0% change when heated from 30–140°C), ensuring consistent performance and reliability under thermal cycling
High Performance: These PCBs provide effective electromagnetic shielding and offer higher current-carrying capacity compared to standard FR-4 boards, enhancing overall reliability and power density in your applications.
Types of Aluminum PCBs TriWin Offers
TriWin Circuits provides versatile Aluminum PCB solutions to meet diverse project requirements
Single Layer Aluminum PCB
The most common type, featuring one copper circuit layer on a dielectric, bonded to the aluminum base. Ideal for simpler, high-power designs.
Double Layer Aluminum PCB
Includes two layers of copper circuitry (top and bottom) with via holes, separated by dielectric layers, all on an aluminum base. Offers greater circuit density while maintaining thermal performance.
Multi-Layer Aluminum PCB
For highly complex designs requiring even greater circuit density, TriWin can provide specialized multi-layer configurations with an aluminum core. (Please confirm if you actively offer this, as it's less common for aluminum base).
Flexible Aluminum PCB
Combines a flexible circuit layer with an aluminum heat sink, ideal for applications requiring both heat dissipation and dynamic bending.
Hybrid Aluminum PCB
Integrates traditional FR-4 layers with an aluminum base, combining the advantages of both materials for specific design challenges.
